  • the present invention relates to a packaging bag made of resin, and more particularly to a packaging bag made of resin that can store the remaining contents even after a part of the contents is taken out.
  • the invention relates to a packaging bag according to the preamble of claim 1.
  • a packaging bag made of a sealable film made of resin is widely used as a bag for packaging foods, bags for storing various small articles, and the like.
  • a packaging bag having a zipper-type mechanism in which the opening part can be easily closed with use of hands after the contents are stored has a high convenience because the performance of storing the remaining contents is good even after a part of the contents is taken out.
  • Such a packaging bag is disclosed, for example, in Japanese Patent Application Laid-Open ( JP-A) No. 08-034 448 .
  • This packaging bag has a rectangular planar shape, and the surroundings are sealed except for the upper part.
  • a convexo-concave zipper is provided on the front and back surfaces of the opening part in the upper part in the width direction.
  • a fracture line for tearing the bag off is formed on the outer circumferential side of the zipper. By breaking this fracture line part, the contents can be taken out via the zipper. After a part of the contents is taken out, the remaining contents can be stored as they are by closing the zipper.
  • the document GB-A-2 172 545 discloses an apparatus for the manufacture of an easy-to-open synthetic resin bag.
  • the packaging bag disclosed in this document comprises a bonding agent which is applied to a part of the bag body above an opening thereof, and a peel-off strip is removably attached to the bonding agent. When this peel-off strip is removed, the upper part of the bag body can be used for closing the opening by bending over the upper part of the bag body.
  • the document DE 1 926 159 U discloses a packaging bag made of a flexible bag-shaped film of synthetic material. On the outer side of one face, a strip off self-adhering material is provided which extends continuously from one edge of the package to the opposite edge. This strip off self-adhering material is usually covered by the edge of an upper film closing the bag. After opening the packaging bag, it can be closed again by pressing the outer film on the self-adhering strip.
  • an object of the present invention is to provide a packaging bag made of resin that can store the remaining contents even after a part of the contents is taken out, wherein the packaging bag is easily openable and closable without providing a zipper, has a storage property equal to that of a bag provided with a zipper, and can be manufactured at a low cost.
  • a packaging bag which comprises: a flexible bag-shaped film made of resin having a front layer and a back layer for storing an object in the bag-shaped film between the front layer and the back layer; wherein the bag-shaped film has an easy-fracture part formed near or at one outer periphery of the bag-shaped film for opening the bag-shaped film.
  • the packaging bag is characterized in that the front layer is a laminate film comprising a front outer layer, a front inner layer, and an adhesive applied on the front outer layer between the front outer layer and the front inner layer, wherein the adhesive is that the front outer layer is peelable from the front inner layer and re-adherable to a film; in that the front outer layer has a non-adhesive part where the adhesive formed on the front outer layer is discontinued, wherein the non-adhesive part is formed along the easy-fracture part and/or a rafter part of the bag-shaped film, if any; and in that the front outer layer can be peeled from the non-adhesive area after the easy-fracture part has been opened, the remaining front inner layer and the corresponding back layer can be folded by placing the back layer front, and the front outer layer can re-adhere to the folded back layer.
  • the front layer is a laminate film comprising a front outer layer, a front inner layer, and an adhesive applied on the front
  • the contents can be easily taken out by fracturing the packaging bag using the easy-fracture part as a starting point. Then, in closing the packaging bag, since the non-adhesive part is exposed at the fractured site, the remaining resin can be folded by peeling off the front layer from this non-adhesive part with use of hands and closing the opening part, and this folded site is covered with the front layer having an adhesive. In taking out the contents again, the opening part can be easily opened by peeling off the front layer.
  • the resin film includes materials obtained by vapor deposition of aluminum on a resin film and materials obtained by laminating aluminum foil on a resin film in addition to those produced only from resin.
  • a planar shape thereof is generally rectangular; peripheries of two long sides are sealed, and a rafter part is formed that is sealed from a generally central part of the two long sides in a direction intersecting the long sides; and the easy-fracture part is formed at the peripheries of the long sides near the end part.
  • the bonding site can be widened in closing the opening part again after the contents are taken out.
  • the non-adhesive layer is provided on a side of the rafter part where the easy-fracture part is not formed, whereby the front layer of the rafter part can be peeled off with use of hands.
  • the bonding site can be further widened in closing the opening part again after the contents are taken out.
  • a planar shape thereof is rectangular; and three sides thereof are sealed to form sealed peripheries, and only one of the short sides forms an opening part, and the easy-fracture part is formed near this opening part.
  • the adhesive is an adhesive that does not give adverse effects in terms of hygiene, and is applied to bond between the films.
  • the adhesive is selected from the group consisting of various polysaccharides derived from natural products such as various cereal starches and galactomannan, proteins such as corn protein, albumin, and gelatin, natural gummy substances, shellac, glycerin, and mixtures obtained by blending these, or a solvent-based adhesive using an acrylic resin or vinyl acetate copolymer adhesive and a solvent such as ethyl acetate.
  • FIGs. 1 to 6 are views describing the use of a packaging bag made of resin according to embodiments of the present invention.
  • This packaging bag P made of resin has an approximately rectangular planar shape, and has peripheries 1 that are thermally fused and sealed, whereby contents can be stored between the front and back surfaces of the film made of resin.
  • the film made of resin is constructed with a laminate film or the like obtained by lamination of an OPP (biaxially extended polypropylene) film or a PET film 5 (front layer) having a thickness of about 10 to 50 ⁇ m and an LLDPE (linear low density polyethylene) film 7 subjected to aluminum vapor deposition having a thickness of about 30 to 50 ⁇ m with an aluminum vapor deposition surface 6 interposed therebetween.
  • OPP biaxially extended polypropylene
  • PET film 5 front layer
  • LLDPE linear low density polyethylene
  • an adhesive 8 may be applied at necessary sites. Nevertheless, an adhesive may be applied on the LLDPE film 7 side or may be applied on both of these.
  • the resin film to be used is not limited to the above-described ones, so that it may be a laminate film or the like having a three-layer structure in which a transparent OPP film or a PET film is disposed as an upper surface and an LLDPE film is disposed as a lower surface with a vapor-deposited PET film (VMPET) interposed therebetween.
  • VMPET vapor-deposited PET film
  • a shielding layer such as a vinylidene chloride film having a high oxygen shielding property may be disposed at the central part of the laminate film.
  • a nylon film having a good printing property may be laminated on the foremost surface side.
  • This packaging bag P made of resin can be produced by various known methods generally known in the art while being loaded with contents.
  • a Vertical Form, Fill and Seal Machine, a Horizontal Form, Fill and Seal Machine, or the like is suitable for use.
  • end parts (corresponding to a rafter part 2 in Fig. 1 ) of the resin shown in Fig. 2 are sealed so that the resin will have a tubular form with an interior 10, and then the lowermost part (corresponding to a lower periphery 1 in Fig. 3 , for example) is sealed to provide a shape with a bottom, followed by putting the contents (M) thereinto.
  • the upper end (corresponding to an upper periphery 1 in Fig. 3 , for example) is sealed, and a generally central part of the sealed part is laterally cut with a cutter to separate a packaging bag made of resin of the lower half (e.g., Fig. 3 ) and, at the same time, to allow the upper half to have a bottom, and contents are put in.
  • a packaging bag made of resin of the lower half e.g., Fig. 3
  • a packaging bag made of resin that packages contents can be produced automatically.
  • an automatic packaging machine such as a HIGH-SPEED HORIZONTAL FORM-FILL-SEAL MACHINE S-5000A manufactured by OMORI MACHINERY CO., LTD. can be used, for example.
  • a notch 3 is formed which is an easy-fracture part that facilitates fracture of the packaging bag P.
  • the notch 3 may be formed near the outer circumferential end part.
  • the shape of the notch 3 is not limited to the one shown in Fig. 3 , and may be another shape. With this notch 3 interposed in between, a non-adhesive part 4 with no adhesive applied thereon is formed at the site that crosses the packaging bag (the site to be fractured).
  • the adhesive 8 applied on the front layer 5 must be such that peeling off can be carried out by pulling with use of hands using the non-adhesive part 4 as a starting point without the need for a particularly large adhesive strength. Then, it may be such that adhesion can be made repeatedly by pressing the peeled-off films again onto each other.
  • an adhesive one can use edible adhesives such as various polysaccharides derived from natural products such as various cereal starches and galactomannan, proteins such as corn protein, albumin, and gelatin, natural gummy substances, shellac, glycerin, and mixtures obtained by suitably blending these. These are applied after being diluted with a denatured alcohol. When such an adhesive is used, the obtained packaging bag will be suitable as a bag for packaging foods.
  • edible adhesives such as various polysaccharides derived from natural products such as various cereal starches and galactomannan, proteins such as corn protein, albumin, and gelatin, natural gummy substances, shellac, glycerin, and mixtures obtained by suitably blending these. These are applied after being diluted with a denatured alcohol.
  • the obtained packaging bag will be suitable as a bag for packaging foods.
  • the method of applying the adhesive is not particularly limited, so that various bonding techniques that are conventionally known in the art can be applied.
  • the adhesive 8 is applied wholly on the surface. But adhesion and peeling-off of the front layer 5 of the packaging bag P in the present invention are carried repeatedly, so it is preferable that the front layer 5 has many non-adhesive parts 8a and such as the adhesive parts 8b forming the pattern illustrated in Fig 4(A) or Fig. 4(B) , or the combination of those patterns, or the combination of those patterns and non-adhesive parts 8c illustrated in Fig 4(C) .
  • the peeling-off and re-adhesion of the front layer 5 is easy. Then after packing the contents to the packaging bag P, the peeled section can be easily opened or shut by the hand.
  • Fig 4(A) shows the pattern applied the adhesive 8 fragmentarily in the straight or curved shape.
  • the strength of adhesion and peeling-off is controlled by the ratio of non-adhesive parts 8a and adhesive parts 8b and the direction of adhesive parts 8b.
  • Fig 4(B) shows the pattern applied the adhesive 8 continually with form of spline. It has the same function as that of the pattern applied the adhesive 8 fragmentarily above described, and can get the higher strength.
  • Fig 4(C) shows the pattern having the combination of those patterns and the non-adhesive parts 8c between those patterns.
  • Non-adhesion part 8c leads to the peeling-off and can secure desired joining strength in each layer.
  • the adhesive 8 can be not harden at the use temperature by the composition, and then adhesion and peeling-off become easy. Furthermore, the adhesion strength or peeling-off strength can be formed freely by diluting the adhesive 8.
  • the packing bag P of the present invention is superior that the formation of adhesion layer 9 in the outer layer 5R can be set by such processing or the combination of those freely.
  • a narrow strip (shown in a virtual line) P1 is broken while being pulled with hands generally in parallel to the short sides using the notch 3 shown in Fig. 3 as a starting point while the packaging bag P on the side containing the contents is pressed down with a hand after the contents M are moved to the side opposite to the position of the notch 3.
  • the front layer 5R in Fig. 3 shows a state of being peeled off with hands for closing again after being already broken.
  • Fig. 3 also shows an enlarged view of the peeled portion.
  • a front film is comprised of a front outer layer 5F and a front inner layer 7F (the other layers shown in Fig. 2 are omitted), and a back film is comprised of a back outer layer 5B and a back inner layer 7B (the other layers shown in Fig. 2 are omitted).
  • the front inner layer 7F and the back inner layer 7B are sealed at their peripheries.
  • the front outer layer 5F is separated from the front inner layer 7F.
  • the opening part is closed again.
  • the method is such that the front layer 5R is peeled off with hands as illustrated in Fig. 3 . Since the broken part is the non-adhesive part 4, the front layer 5R can be easily peeled off with hands.
  • the short side of the broken and open packaging bag P (7F, 7B, and 5B in the enlarged view of the peeled section) is folded so as to insert it between the peeled front layer 5R (5F in the enlarged view of the peeled section) and the LLDPE film 7 (7F in the enlarged view of the peeled section), and the front layer 5R is folded toward the back surface side of the packaging bag P so as to cover it from above and pressed onto the back surface of the packaging bag P for bonding and closing.
  • the packaging bag can be easily opened and closed without providing a zipper in the packaging bag, so that the contents can be stored in a good condition.
  • the adhesion area may be further increased. Namely, as illustrated in Fig. 6 , the folded part on the short sides of the packaging bag P that has been opened by being broken is enlarged to increase the adhesion area. In this case, as illustrated in Fig. 3 , the rafter part 2 on the side where the notch 3 is not formed is made as a non-adhesive part 4, and the front layer 5L is peeled off from the rafter part 2 with hands.
  • the short side of the packaging bag P that has been opened by being broken (the front layer 5R is not peeled) is folded so as to be inserted between the peeled front layer 5L and the LLDPE film 7.
  • the front layer 5L is folded toward the back surface side of the packaging bag P so as to cover it from above, and is pressed onto the back surface of the packaging bag P for bonding and closing.
