Description

  The present invention relates to a child safety carton package, said package being made of a fiber-based material outer sleeve and an insert which can be pulled out of said sleeve and carries a packaged product And a locking mechanism between the sleeve and the insertion portion that prevents the child from pulling out the insertion portion from the sleeve. In addition, the present invention includes specific fiber baseboard applications for the carton package described above.

  Consumer packages for drugs or other products that pose a risk to small children need to be designed to prevent children from easily touching the contents of the package. In a box-type package consisting of a sleeve and a sliding insert that can be pulled out of the sleeve, this is sized to require a typical adult hand for quick operation. Achieved by a locked mechanism. There are standards, including international standard ISO 8317, in tests that define child safety that must be passed in order for the package described above to be acceptable to the market.

  Pediatric safety drug packages having locking means have been manufactured from plastic, but more recently, paper boards and card boards have also been introduced or proposed as materials for the above-described packages.

  EP 1 002 744 A1 relates to a two-part paper board package having an internal paper board sliding card containing the product and a pediatric safety locking system arranged between the external paper board sleeve Explains. To lock the pieces, the system has an inner sliding tab that contacts the inner shoulder of the sleeve. The part is released by pressing the release button. The thickness of the paper board used is in the range of 0.2 mm to 0.7 mm and is usually described as having a clay coating on one or both sides. The coating is taught to provide a high degree of smoothness and an excellent graphic print surface.

  The weakness in the mechanism according to EP 1 002 744 A1 is pointed out in WO 02/38454, ie the locking system depends on choosing a sufficiently thick material for the outer sleeve. If the material is too thin, the safety of the lock is at risk. The teachings in WO 02/38454 teach an improved structure to achieve a lock that is safe against wear and wear in repeated use, even when thin cardboard materials are used. It is about.

  More particularly, the child safety package described in WO 02/38454 comprises an outer sleeve and a slidable insert manufactured by folding and bonding cardboard sheets, A locking system is provided between them. On the inner side of the sleeve, a catch tab and an operation tab which are continuously arranged in the sliding direction of the insertion portion are provided near the side wall facing the sleeve. The insertion part is likewise provided with a locking tab beside its opposing side walls. To be manufactured from a cardboard, the tabs in the sleeve and in the insert are flexible. Since the insert is pushed into the sleeve, the locking tab will slide under the catch tab and will be under the operating tab. Nonetheless, the two catch tabs have a downward slope in the sliding direction so that they engage the locking tab and prevent the sleeve from being pulled out. In order to open the package, the user must press the operating tab against the locking tab with one finger through the two holes in the sleeve to release the locking tab from engagement, so that the other The insertion portion can be pulled out of the sleeve by hand.

  Previously unpublished international application PCT / SE02 / 01600 owned by the applicant describes an improved locking system for a two-part paperboard package for medicines and the like. ing. A specific feature of the package is the location of the hole for releasing the locking mechanism on the opposite edge or side wall of the outer sleeve. In general, the teachings are intended to simplify the structure and facilitate manufacture.

  Another prior art two-part carton package for pharmaceuticals is described in US Pat. No. 6,491,211. The outer carton is formed from any suitable material, sulfate paperboard, clay-coated recycled or recycled paperboard blank, and is 0.008 inches to 0.028 inches (about 0.2 mm to 0.7 mm). It is taught that having a thickness is particularly preferred.

  A different type of chemical package is a press-through or blister pack, comprising a plastic sheet with flexible bubbles and a sheet of aluminum foil that can be smashed attached to the plastic sheet. The pills contained in the compartments or blisters between the sheets are removed by pressing to force it through the tearing foil. EP 0 771 737 describes a blister pack, which is made pediatric safe by providing it with an unbreakable backing sheet, which comprises a heat seal layer, a foil layer, It comprises a polyester layer of other strong polymeric material and an outer paper layer for printing. The backing sheet has a cut line cut that is almost invisible as an opening function that opens the package by peeling off the backing sheet, and the use of the opening function requires adult cognitive skills, as opposed to children This cannot be used with recognition technology. WO 03/066323 also describes a laminate for a child safety blister pack that includes a heat seal layer, a tear resistant polymer layer, and a paper board substrate for printing. Lamination is provided with a weakened portion that is easily understood by adults but controlled to direct the opening of the package according to instructions that are difficult for children to understand.

  As a material for disposable consumer packages, fiber baseboards are generally preferred over plastics because of cheaper materials or manufacturing costs and environmental considerations. Nonetheless, when the carton package was subjected to the Applicant's pediatric safety test, it was quickly determined that despite the progress, the package described above still did not meet the requirements. . While the prior art has focused on improving the locking mechanism to increase its structural rigidity and wear resistance and to withstand children's tampering, its testing So, the weak point was not the design of the locking mechanism, but rather the material itself. Whether curiosity or for any other reason, a child can easily open it by touching the board package and easily touch the contents.

  A child's interesting feature in the package is a hole or other accessory required for the locking mechanism. However, the child tears the sleeve starting from the insert opening or seal rather than the hole. From there the material loses integrity and tears.

  It is therefore an object of the present invention to provide a carton package of fiber based material for chemicals and the like that eliminates the structural weakness problem described above. In particular, it is an object of the present invention to provide a package that more desirably prevents children from touching the contents by improving the fiber-based material used in the package. Thereby, an improved pediatric safety package can be obtained while at the same time substantially retaining the advantages of paperboard or cardboard materials when compared to plastic-only packages such as those used in the prior art.

  The object of the present invention is to increase the strength of the package, in particular without having to change the overall design and manufacture, so that the improvement is easily realized and apart from the material, the manufacturing cost of the package Is not to increase.

  According to the present invention, the above object is achieved through a two-part pediatric safety carton package for drugs or other products that can be dangerous for children, which is extruded to increase tear resistance. It has an outer sleeve made from a board reinforced with a molded coating polymer.

  The reinforcement may be a highly resilient polymer layer coated on a fiber baseboard. Suitable coating polymers for use in the present invention are those selected from the group consisting of polyesters, polyamides, polypropylenes and polycarbonates, with polyesters being preferred, with polyethylene terephthalate (PET) being particularly preferred.

  The board can have a polymer coating on one side thereof, which side is then used on the outer side of the sleeve. A polymer coating covering the outside of the sleeve prevents the child from getting wet with the teeth and tearing the material. Nevertheless, the board is preferably provided with a polymer coating layer having good strength and elasticity on both sides. In any case, the coating polymer can be used to form the heat seal necessary to keep the sleeve folded together from the blank of the coating board.

  More preferably, the board is provided with a multilayer coating comprising an inner reinforcement layer of a polymer such as PET, which has excellent strength and elasticity, and an outer heat seal layer of polyolefin. The multilayer coating described above can be applied to one side of the board or, preferably, to both sides of the board. Adjacent layers can be brought to the board simultaneously by coextrusion.

  In the carton package according to the invention, not only the sleeve but also the insert can be manufactured from a board that is coated with a strong and resilient polymer reinforcement layer. In particular, the end face of the insert that closes the open end of the sleeve has the advantage of having a polymer coating, so that the outside of the package has a similar polymer reinforcement throughout. The insert is preferably made from the same polymer extrusion coating board as the outer sleeve.

  Reinforcing boards used specifically for the outer sleeve of the carton package can have a structure that allows the raw cutting edge to peel into a thin layer when subjected to sufficient tearing force. Even with such a tear, along with the heat seal, the inner material layer containing the polymer coating on the inside keeps the package closed, thus succeeding in preventing children from touching its contents I understood that.

  Alternatively, it is possible to take special measures to strengthen at least the outer cut edge of the outer sleeve in order to prevent delamination, i.e. peeling, of the outer material layer at the first location. As examples of the above-mentioned techniques, the edge of a polymer-coated board is skived and folded, the adhesive is applied to the cut edge or the edge is covered with a protective film.

  In the carton package according to the present invention, the sleeve includes four longitudinal side walls parallel to the sliding direction of the insertion portion, a rear wall, and an open end that allows the insertion portion to be pulled out of the sleeve. A first stop tab extending from the first longitudinal wall to the second longitudinal wall and at least partially separated from the first longitudinal wall and the second longitudinal wall. One stop tab and a first locking edge provided on the insertion portion may be provided. The insertion portion is prevented from moving from the sleeve when the first locking edge and the first stop tab are in contact, while the first locking edge allows the user to elastically deform a portion of the insertion portion. Thus, it can be moved so that movement past the first stop tab is possible.

  For operation of the locking mechanism, the outer sleeve can have one or more holes that allow the lock to be released by the user's finger.

  The present invention further includes the use of a polymer extruded coating board for a child safety carton package for use in hazardous products such as drugs, the package comprising an outer sleeve, a slidable insert, and an outer And a locking mechanism between the sleeve and the insertion portion.

  The coating board used according to the invention has already been described. Therefore, a board in which both sides are coated with a reinforcing polymer having excellent strength such as PET and elasticity and any heat seal polymer inside the polyolefin is preferable.

  The above-mentioned board reinforced with an extruded polymer coating can be used for the outer sleeve and the slidable insert, which will also form the locking mechanism of the carton package.

The board base used in the present invention may be a kraft board with a weight of 170 g / m ² to 500 g / m ² , preferably 200 g / m ² to 300 g / m ² . An extruded coating layer of PET or other suitable high strength elastic polymer has a weight of 30 g / m ² to 100 g / m ² , preferably 40 g / m ² to 60 g / m ² . Extruded outer heat seal layers with polyolefins such as low density polyethylene (LDPE) or polypropylene (PP) have a weight of 15 g / m ² to 60 g / m ² , preferably 20 g / m ² to 40 g / m ² . It's okay. The coating board is used for the outer sleeve or the insert or both, and the polymer coating reinforces the board by increasing its tear strength and is at least 2000 mN, preferably 2500 mN or more according to the standard SCAN-P 11:96. Has the advantage of

  The present invention is described in detail below with reference to the drawings.

  For its general structure, the packages shown in FIGS. 1-8 are described in International Application PCT / SE02 / 01600, which is included in this disclosure by this reference. Another example of a package structure having a locking mechanism applicable in connection with the present invention is described in WO 02/38454, which is also included in this disclosure by reference. It is.

  FIG. 1 shows a package 1 according to a preferred embodiment of the present invention. The package comprises an essentially parallelepiped outer sleeve 2 and an insert 3 intended to hold the contents of the package. The sleeve 2 and the insert 3 are preferably produced by folding and heat-sealing a blank produced from an extruded coated cardboard material (see below). The insertion portion 3 can be inserted into the sleeve 2 through the opening 4 of the sleeve 2 in the sliding direction S indicated by a double arrow in FIG. FIG. 1 shows the package 1 with the insertion part fully inserted. FIG. 2 shows the package 1 in a state where the insertion portion 3 is partially pulled out, and the contents of the package can be touched.

  The sleeve 2 comprises four longitudinal walls that are substantially parallel to the sliding direction S. The longitudinal walls are an upper wall 2a, a lower wall 2b, a first side wall 2c, and a second side wall 2d. The upper wall 2a and the first side wall 2c are recognized in FIGS. it can.

  In the opening 4, each of the side walls 2c, 2d has a grip notch 5, in which the insert 3 can be grasped with a finger to be pulled out. The width of the package is preferably configured such that the insert 3 can only be gripped by a person with a sufficiently large hand for this purpose. This means that the small child's thumb / index finger grip does not reach the entire width of the package to pull out the insert 3.

  At one end, the insertion part 3 preferably has a beam-like part 6 produced by folding a blank of the insertion part (see below). The beam is stiff enough that the child cannot deform the end of the insert and reach the contents of the package by that method, or is extremely difficult.

  In the opening 4, the sleeve 2 preferably has two tabs that are folded inward substantially parallel to the upper wall 2a and the lower wall 2b, respectively (see below). This strengthens the upper and lower edges in the opening 4 and makes it impossible or difficult for the child to tear open the sleeve 2 at these edges to reach the contents of the package. means.

  FIG. 3 shows a sleeve blank 2 'produced from an extruded coated cardboard that is formed into the sleeve 2 by folding and heat sealing. As shown in FIG. 3, the sleeve blank 2 'reinforces the sleeve opening 4 by being folded inward substantially parallel to the upper wall 2a and the lower wall 2b, respectively, as described above. Two tabs 21 and 22 are provided.

  The sleeve blank 2 'comprises a first part 2a' intended to form the upper wall 2a of the sleeve and a second part 2b 'intended to form the lower wall 2b of the sleeve. . The third part 2c ′ and the fourth part 2c ″ are intended to form the first side wall 2c of the sleeve, and the fourth part 2c ″ is positioned inside the third part 2c ′. Is intended to be. Correspondingly, the fifth part 2d ′ and the sixth part 2d ″ are intended to form the second side wall 2d of the sleeve.

  The seventh part 7a 'and the eighth part 7b' are intended to form a first stop tab 7a and a second stop tab 7b, respectively, which lock the insert 3 in the sleeve 2. This will be explained in more detail below. As shown in FIG. 3, the portions 7a 'and 7b' forming the stop tab have an essentially triangular shape, and one of the points of the triangle is the fourth portion 2c "and the sixth portion, respectively. Is located at the free longitudinal edge of the portion 2d ″. The seventh part 7a ′ and the eighth part 7b ′ respectively project outside the free longitudinal edges of the fourth part 2c ″ and the sixth part 2d ″, which are inside the free edge, It is intended to be folded at each line 7a ", 7b".

  Alternatively, the portion forming the stop tab has a shape other than a triangle, for example, a rectangle.

  When the sleeve blank is folded, the fourth portion 6c "and the sixth portion 2d" have their free longitudinal edges, respectively, the sleeve upper wall 2a, the first side wall 2c and the second side wall 2d. It is bent so as to be positioned at the connection between the two. The seventh part 7a 'and the eighth part 7b' are then positioned at an angle with respect to the upper wall 2a of the sleeve, the first side wall 2c and the second side wall 2d, respectively. It is bent so that They then form a first stop tab 7a and a second stop tab 7b, respectively. Each stop tab is consequently connected to a respective side wall and forms an angle with respect to the respective side wall by bearing on the upper wall.

  FIG. 4 shows the sleeves folded and sealed together, with specific recessed portions represented by dashed lines. The first stop tab 7a and the second stop tab 7b are located inside the sleeve at respective corners formed by the upper wall 2a, the first side wall 2c, and the second side wall 2d, respectively. The first stop tab 7 a and the second stop tab 7 b are further located at a distance from the rear wall 2 c of the sleeve 2.

  FIG. 5 shows a perspective view of a portion of the sleeve 2 cut out at an angle from below for clarity. The second stop tab 7b extends from the inside of the second side wall 2d to the inside of the upper wall 2a. The stop tab 7b consequently extends at an angle with respect to the sleeve walls 2a, 2d, so that at least a part of this is in the area for the movement of the insert 3 in the sliding direction S. Located in the part. As will be described in more detail below, the stop tab 7b acts in contact with the insert 3 to prevent the insert 3 from being pulled out of the sleeve 2. The fact that the stop tab 7b extends inside and is separated from the wall of the sleeve ensures that the functionality of the stop tab 7b is not affected by sleeve wear after repeated use. Furthermore, a solution has also been obtained in which the stop tab is separated from the sleeve wall without the need for a means such as a protrusion intended specifically for that purpose.

  As shown in FIG. 5, the stop tab 7 b is further angled with respect to the sliding direction S of the insertion portion 3, so that the portion of the stop tab located closest to the opening 4 of the sleeve is: It is located closer to the sleeve walls 2a and 2d than the other parts of the stop tab. Thereby, when the insertion portion is inserted into the sleeve, the locking portion of the insertion portion 3, which will be described in more detail below, passes through and passes through the stop tab 7 b due to elastic deformation when contacting the stop tab 7 b You can then “snap” back (bounce back). This design of the stop tab 7b further means that it is very strong and can withstand large forces when an attempt is made to pull it out without a clever technique of unlocking, as described below.

  FIG. 6 shows the insertion part 3, and FIG. 7 shows a blank 3 'for producing the insertion part by bending and appropriately heat-sealing. The blank of the insertion part is provided with a part 6 'for producing the beam 6 described above.

  The insertion portion 3 includes a bottom surface portion 3a ′, a first side surface portion 3b, and a second side surface portion 3c. In the inserted state of the insertion portion, the side surface portion 3b. 3 c is located substantially parallel to the side walls 2 c and 2 d of the sleeve 2 and close to the side walls 2 c and 2 d of the sleeve 2. The side surface portions 3 b and 3 c extend substantially in the sliding direction S for insertion in the sleeve 1. The side surface portions 3b and 3c are connected to the bottom surface portion 3a and oriented substantially perpendicular thereto.

  Each side surface portion 3b, 3c has notches 8a, 8b, in which a first lock edge 9a and a second lock edge 9b are formed, respectively. In the inserted state of the insertion portion, the lock edges 9a, 9b are located slightly closer to the sleeve rear wall 2e than the stop tabs 7a, 7b, and this attempt is made when an attempt is made to pull out the insertion portion from the sleeve. In the area of the lock edges 9a, 9b, they are prevented by the side portions 3b, 3c which are in contact with the first stop tab 7a and the second stop tab 7b, respectively.

  As shown in FIG. 3, the sleeve blank 2 'has holes 10a' and 10b 'in the third part 2c' and the fifth part 2d ', hereinafter referred to as outer holes 10a' and 10b '. , The fourth portion 2c "and the sixth portion 2d" have holes 10a ", 10b", hereinafter referred to as inner holes 10a ", 10b". The inner holes 10a ", 10b" are each covered by a flap 101 connected to the sleeve blank at the substantially straight edges of the respective inner holes, so that the flaps can pivot about the straight edges.

  In the finished state of the sleeve 3, the first side wall 2c and the second side wall 2d are respectively a third part 2c ′ and a fourth part 2c ″, and a fourth part 2d ′ and a sixth part 2d ″. And a portion. In this respect, the third portion 2c ′ and the fifth portion 2d ′ are located outside the fourth portion 2c ″ and the sixth portion 2d ″, respectively. The flap 101 and the outer holes 10a ', 10b' are designed so that the flap 101 extends outside the area of the respective outer hole 10a ', 10b' in size, so that they are inside the package. It is possible to turn only in the direction. In that case, the flaps are moved out of the package and are therefore prevented from being damaged.

  As shown in FIGS. 1, 2 and 4, the inner holes 10a ″ and 10b ″ and the outer holes 10a ′ and 10b ′ are formed on the first side wall 2c of the first folded hole 2 in the first hole 2a. 10a, and a second hole 10b is formed in the second side wall 2d. The package is designed to allow the user to grip the entire package with the thumb / index finger grip. The user can then press his finger against each of the holes 10a, 10b to move the flap 101 inward, and press the side portions 3b, 3c of the insertion portion inside the sleeve, so As shown in FIG. 8 (only one side surface portion 3c is shown), at least in the area of the lock edge, the side surface portion is elastically deformed so as to be inclined inward in the sleeve 2. The lock edges 9a, 9b then move away from the sleeve sidewalls 2c, 2d. Thus, the lock edges 9a and 9b are located outside the area of the stop tabs 7a and 7b as shown in the sliding direction S of the insertion portion 3, and the insertion portion is The thumb / index finger grip of the other hand can be pulled out of the sleeve by grasping the grip notch 5 (described above with reference to FIGS. 1 and 2).

  The width of the package is preferably such that a person with a small hand, such as a child, cannot grasp the entire package by spreading his thumb and forefinger to operate the lock with the lock edges 9a, 9b. The package opening, as a result, requires the use of both adult hands, which are of a common size.

  The design of the locking portion on the longitudinal side portion of the insert provides a robust construction and therefore, in combination with a reinforcing board, the risk of the insert being pulled out by force, for example by a child, is reduced.

  FIG. 9 is a schematic cross-sectional view of a coating board applied to the carton package described above with reference to FIGS. The coating board forms the blank shown in FIGS. 3 and 7 and consequently the entire package, ie the sleeve and the insert, and thus also the locking mechanism that is part of the sleeve as will be described. It becomes.

The coating package board 11 of FIG. 9 comprises a board base 12, which is a multilayer craft board having a weight in the range of 170 g / m ² to 500 g / m ² , preferably a weight of 200 g / m ² to 300 g / m ^2. It is preferable that On both sides of the craft board base 12, there is an extruded layer 13 of a strong and elastic polymer, preferably polyethylene terephthalate (PET), each PET layer having a weight of 30 g / m ² to 100 g / m ² . Preferably having a weight of 40 g / m ² to 60 g / m ² . The multilayer structure is symmetric with respect to the board base 12, and the PET layers on the opposite sides of the board base then have a similar coating weight.

The coating board 11 shown in FIG. 10 differs from that shown in FIG. 9 mainly in that the extruded polymer coating layer 13 is only on one side of the board base 12. The board base material and weight may be as described above, and a single polymer layer may have a weight of 30 g / m ² to 100 g / m ² , preferably 40 g / m ² to 60 g / m ^2. A layer is preferred. The PET coated side of the board will be used to form the outer surface of the sleeve and the insert in making the package.

FIG. 11 shows a coating board 11 that is preferably used in the package described in FIGS. The coating board of FIG. 11 corresponds to that shown and described in connection with FIG. 9 above, but has an outer heat seal polymer layer 14, preferably of LDPE, on both sides thereof. Each of the LDPE layers 14 has a weight of 15 g / m ² to 60 g / m ² , preferably 20 g / m ² to 40 g / m ² . The PET layer 13 and the LDPE layer 14 can be provided to the fibrous board base 12 in a single manufacturing process by coextrusion.

  In the manufacture of the package 1, the polymer coating layers 13, 14 are used to form a heat seal as required for the sleeve and insert. FIG. 12 shows the bottom side of the sleeve 2 with two parallel seams 15, the two opposite edges of the sleeve blank 2 ′ being brought to overlap the lower wall portion 2 b ′. In the case of a board 11 having a polymer coating on both sides as shown in FIGS. 9 and 11, the coating layer 13 or 14 of the blank overlap portion is fused with sufficient heat to melt the polymer. In the case of the single coated board of FIG. 10, the overlap portion is sealed by melting a portion of a single polymer layer 13 and attaching it to the other portion of the adjacent uncoated board surface. Is done.

  13 and 14 show the protection of the seam 15 of the outer sleeve 2 against delamination of the coating board as another embodiment of the present invention. Delamination starting from the exposed seam 15 on the outside of the package is one of the possible ways of breaking the package that could be damaged by the hands of the children. Delamination can occur either by peeling the polymer coating from the board base or by peeling between adjacent layers of the multi-layer fibrous board.

  In FIG. 13, the edge portion 16 of the blank 2 ′ made from the coating board 11 as shown in FIG. 11 and having the design as shown in FIG. Skived from one side of the blank. It should be understood that the above skiving finish is in particular performed on the part of the blank 2 ′ that forms the exposed seam edge 15 on the outside of the finished sleeve 2.

  In FIG. 14, a seam that is folded and heat sealed to form the sleeve 2 is shown between the overlapping portions 17, 18 of the blank 2 'of FIG. The portion 17 with the skived edge portion 16 is the outer board portion of the seam, and on the outside of the sleeve, more particularly the blank 2 'and the sleeve 2 as shown in FIGS. 3 and 8, respectively. It is located on the bottom surface of such a structure.

  As shown in FIG. 14, the skived edge portion 16 of the outer board portion 17 with reduced material thickness is double bent and the outer coating layer thus ties the fibrous board base 12 at the seam edge 15. Encloses and extends to lie against the outer coating layer of the inner board portion 18. The seam between the portions 17, 18 is generated by heat sealing the adjacent heat seal layers 14, 14 'in the area denoted 19 in FIG. 14, and the out heat seal layer 14' of the inner portion 18 is The inner and outer portions 17 are fused with the folded outer heat seal layer 14. If desired, an adhesive can be applied to the surface of the raw board base 12 produced by skiving finish to provide the inner structure strength to the fold.

  Another way to shield the seam 15 to avoid delamination is to apply an adhesive to the cut raw edge to close the pores of the fibrous board base 12. The above-mentioned adhesion is preferably performed on any cut edge portion exposed to the outside of the package 1.

  In the embodiment shown in FIG. 15, the edge portions of the blank 2 'forming the seam 15 extend the cutting edges to provide protective contact with each other so that they can withstand the risks of tampering and delamination. .

  FIG. 16 shows, as another embodiment, a raw cut edge in the seam 15 and a shield around the hole 10 in the sleeve 2 with a cover with a protective film 20 bonded to a strong and resilient plastic material. Indicates. According to FIG. 17, a similar protective film 20 is stuck around the opening portion 4 of the outer sleeve 2 in order to shield the cut edge 21 so as not to suffer mischief and delamination. Otherwise, the sleeve 2 material may be any one of those described in connection with FIGS.

The coated board was prepared using a Strato Enso grade Cupforma Classic package board with a weight of 210 g / m ² as the board base. The board was extrusion coated on one or both sides with a PET layer weighing 50 g / m ² . The tear strength measured according to the standard SCAN-P 11:96 is presented in the following table:
