Description

  The present invention relates to a hanger member used as a handle when carrying a package and a package with a hanger.

  In general, as a hanger (also referred to as a handle, a handle, a handle, or a handle) attached to a package, the hanger is joined by a pressure-sensitive adhesive layer or an adhesive layer provided on a base material constituting the hanger. There are a tack type and a welding type joined by heat welding such as heat seal, fusing seal, impulse seal and the like. For example, a suspension band is known in which both ends are joined to the surface of a heat-shrinkable film for packaging a plurality of articles with an adhesive (see, for example, Patent Document 1). In addition, as a method of manufacturing a shrink-wrapped body with a handle for carrying, a method of heat-welding both ends of a belt-like sheet to the surface of the shrink film by an impulse seal or the like, an adhesive such as a vinyl acetate emulsion type or an isocyanate type is used. A method of joining by using is known (see, for example, Patent Document 2).

  However, tack-type hangers have a wide selection of base materials and packaging materials, but there is a problem that they are easy to peel off when carrying heavy objects (weak to the load over time). Although it can withstand heavy objects, in order to obtain sufficient adhesive strength, the materials that make up the base material and the package must be the same, and the package is also welded at a high heat seal temperature. There was a problem that the surface of the glass was damaged by heat and did not look good.

An object of the present invention is a hanger member used as a hanger for a package body, and the type of the base material and the material type of the package body constituting the hanger member can be widely selected, and is resistant to load over time. Another object of the present invention is to provide a hanger member that can withstand carrying heavy objects.
Another object of the present invention is to provide a hanger member that can exhibit the above characteristics even under high temperature and high humidity.
Still another object of the present invention is to provide a hanger member that can exhibit the above characteristics even in a low temperature environment such as a cold region.
Moreover, the objective of this invention is providing the hanger member which can exhibit the said characteristic under various climatic conditions.
Furthermore, the objective of this invention is providing the package body with a hanger to which the hanger member which has the above outstanding characteristics was joined.

  As a result of intensive investigations to achieve the above object, the present inventors have widely selected the type of base material and the type of packaging material by providing specific resin layers on at least both ends of one side of the belt-like base material. In addition, the present inventors have found that when bonded to a package, it is strong against a load with time and can exhibit a strength that can withstand carrying heavy objects.

  That is, the present invention provides a hanger member in which a heat-sensitive resin layer containing a heat-sensitive base polymer and a tackifier is provided on at least both ends of one side of a belt-like substrate.

  Moreover, this invention provides the package body with a hanger by which the both ends of the hanger member of the said invention are being fixed to the package body surface by the heat sensitive resin layer.

  According to the hanger member of the present invention, the type of base material of the hanger member and the type of material of the packaging body are not limited and can be attached to various packaging bodies. Even in this case, the adhesiveness can be firmly maintained without peeling. These characteristics can also be exerted under various climatic conditions such as cold regions and hot and humid regions.

  Embodiments of the present invention will be described below with reference to the drawings as necessary. FIG. 1 is a schematic cross-sectional view showing an example of the hanger member of the present invention. In FIG. 1, the hanger member 1 is composed of a base material 10 and a heat-sensitive resin layer 11 provided on the entire surface of one side of the base material 10.

  The substrate 10 is not particularly limited as long as it has a mechanical strength that can be used as a hanger. However, it is preferable that the substrate 10 has a small amount of heat and heat resistance when it is lifted by grasping the handle part. For example, polyethylene terephthalate ( PET), polyester resins such as polybutylene terephthalate (PBT), polyethylene naphthalate (PEN); polyolefin resins such as polyethylene and polypropylene; styrene resins such as polystyrene; polyvinyl chloride; Examples include stretched plastic films or sheets; synthetic papers; and laminates thereof. The base material 10 should just have the strip | belt-shaped shape provided with the part (hanging part) gripped with a hand and the attachment site | part (adhesion part). Here, the belt-like base material 10 is not only one having a constant width between the hanging portion and the bonding portion, but also having a shape (dumbbell shape) where the width of the bonding portion at both ends is wider than the hanging portion, The design can be changed to such an extent that it does not impair the function as a hanger, such as one that becomes thinner or thicker from both ends of the hand portion toward the central portion in the longitudinal direction.

  The thickness of the base material 10 is 10 micrometers-5 mm, for example, Preferably it is 15-1000 micrometers, More preferably, it is about 20-500 micrometers. If the thickness is too thin, it cannot withstand the weight of the adherend and tends to stretch or tear, and if it is too thick, it is difficult to grasp by hand.

  The heat-sensitive resin layer 11 is composed of a heat-sensitive resin composition containing a heat-sensitive base polymer and a tackifier (tackifier) as main components, and is activated by heating to bond and fix the hanger member and the adherend. can do.

  Examples of the heat-sensitive base polymer include poly (meth) acrylic acid ester, styrene- (meth) acrylic acid ester copolymer, ethylene-vinyl acetate copolymer, polyvinyl acetate, and vinyl acetate- (meth) acrylic. Examples include acid ester copolymers, ethylene-vinyl chloride copolymers, ethylene- (meth) acrylic acid ester copolymers, ethylene- (meth) acrylic acid copolymers, and thermoplastic resins such as polyurethane. Among these, an acrylic polymer containing (meth) acrylic acid ester as a monomer component, a vinyl acetate polymer containing vinyl acetate as a monomer component, and the like are preferable. In particular, an ethylene-ethyl acrylate copolymer or other ethylene- Acrylic polymers such as (meth) acrylic acid ester copolymers are preferred. These base polymers may be used alone or in combination of two or more. The usage-amount of a base polymer is 30 to 99 weight% with respect to the total amount of a thermosensitive resin composition, for example, Preferably it is 35 to 95 weight%, Especially about 40 to 80 weight%.

The tackifier has an action of improving the holding power particularly at high temperatures. For example, rosin resins (rosin, polymerized rosin, hydrogenated rosin and derivatives thereof, resin acid dimer, etc.), terpene resins ( terpene resins, aromatic modified terpene resins, hydrogenated terpene resins, terpene - phenol resin), petroleum resin (aliphatic (C ₅ series), aromatic (C ₉ series), alicyclic), coumarone - Indene resin, styrene resin, phenol resin and the like are used. Of these, terpene resins are preferably used because they are excellent in heat resistance and compatibility. A tackifier can be used individually or in combination of 2 or more types. The usage-amount of a tackifier is 1 to 40 weight% with respect to the total amount of a thermosensitive resin composition, Preferably it is 3 to 20 weight%, Especially about 5 to 15 weight%. If the amount of the tackifier used is too small, the effect of improving the holding power at high temperatures is difficult to obtain, and if the amount used is too large, the effect is difficult to obtain, which is not economically preferable.

  The thermosensitive resin composition constituting the thermosensitive resin layer 11 may contain an elastomer in order to improve the holding power at low temperatures. Examples of the elastomer include natural rubber; olefin-based elastomers such as ethylene-propylene copolymer, ethylene-propylene-diene copolymer, polybutene, polybutadiene, polyisobutylene, polyisoprene, chlorinated polyethylene; polychloroprene, chloroprene- Chloroprene-based elastomers such as styrene copolymer, chloroprene-isoprene copolymer, chloroprene-acrylonitrile copolymer; styrene-butadiene copolymer, styrene-butadiene-styrene copolymer, styrene-isoprene-styrene copolymer, styrene -Styrene elastomer such as isoprene copolymer, styrene-isoprene-butadiene-styrene copolymer; Thermoplastic polyester elastomer; Thermoplastic polyurethane elastomer Chromatography; and thermoplastic elastomers such as thermoplastic acrylic elastomer is used. Of these, olefin-based elastomers are preferably used. An elastomer can be used individually or in combination of 2 or more types. The usage-amount of an elastomer is 0-50 weight% with respect to the total amount of a heat-sensitive resin composition, for example, Preferably it is 5-40 weight%, Especially about 15-35 weight%. If the amount of the elastomer used is too small, it is difficult to obtain the effect of improving the holding power at low temperatures, and if the amount used is too large, it is uneconomical.

  The heat-sensitive resin composition constituting the heat-sensitive resin layer 11 may further contain a lubricant for preventing blocking of the roll product and improving line suitability. As the lubricant, for example, a higher fatty acid-based lubricant is used, and typical examples thereof include higher fatty acids having about 10 to 20 carbon atoms such as stearic acid, lauric acid, and oleic acid; stearic acid amide, ethylenebisstearyl. Higher fatty acid amides such as amides; salts of higher fatty acids such as calcium stearate, zinc stearate, zinc laurate, sodium oleate, and the like. The amount of the lubricant used is preferably about 2000 to 4000 ppm with respect to the total amount of the thermosensitive resin composition. If the amount of the lubricant is too large, the lubricant bleeds out on the surface of the glue, causing problems such as a decrease in adhesion and a decrease in strength over time.

  In addition, various additives such as a plasticizer, an antioxidant, and a colorant may be added to the thermosensitive resin layer 11 as necessary.

  It is preferable that the heat-sensitive resin layer 11 is not sticky at normal temperature in terms of handleability. The activation temperature of the thermosensitive resin layer 11 is, for example, 80 ° C. or higher (for example, about 80 to 150 ° C.), preferably 100 ° C. or higher (for example, about 100 to 130 ° C.). If the activation temperature is too low, blocking is likely to occur at room temperature, and if the activation temperature is too high, damage may occur such as melting of the adherend surface. The said activation temperature can be adjusted by selecting suitably the base polymer which comprises the thermosensitive resin layer 11, the kind and quantity of a tackifier, another additive, etc. Moreover, if the activation temperature is 80 ° C. or higher, the heat-sensitive resin layer 11 can be provided on the entire surface of the hanger member, and it is preferable that the resin does not become sticky due to the body temperature of the hand.

  The thickness of the thermosensitive resin layer 11 is, for example, about 10 to 100 μm, preferably about 20 to 60 μm.

  The heat-sensitive resin layer 11 can be formed by a method such as a method in which a heat-sensitive resin composition as described above is melt-extruded and coated, or a method in which a heat-sensitive resin composition solution is applied by dissolving in a suitable solvent. In the present invention, a method by melt extrusion coating is preferably used in that a film thickness capable of exhibiting sufficient holding power even for heavy objects can be formed.

  The hanger member 1 of the present invention can be formed, for example, by providing the thermosensitive resin layer 11 on at least both ends of one side of the base material 10 formed into a belt shape by the above method. As shown in FIG. 1, the heat-sensitive resin layer 11 may be provided on the entire surface of one side of the substrate 10, or may be partially provided on both ends of the one surface of the substrate 10. The hanger member 1 usually has a belt-like shape with a width of about 10 to 100 mm and a length of about 100 to 1000 mm.

  In the hanger member 1 of the present invention, when the heat-sensitive resin layer 11 is activated by heating, both ends in the length direction are fixed to the adherend surface as adhesive portions, and the center hanging portion is held by hand and carried. Used as a hanger (hanger, handle). By holding the suspension part by hand, the width direction of the hanger member 1 may be shifted (folded in a wrinkle shape). For attachment, for example, the surface of the hanger member 1 on the heat-sensitive resin layer 11 side is overlaid on the surface of the package, and then heated and fixed by a method such as pressing a hot plate from the substrate 10 side or pressing with a heating roller. Is done. The heating temperature is appropriately selected according to the activation temperature of the thermosensitive resin layer 11.

  The hanger member 1 of the present invention can be attached to an adherend made of various materials. Therefore, the combination of the base material 10 constituting the hanger member 1 and the material of the adherend can be set extremely variously. Such adherends include, for example, paper such as Japanese paper, synthetic paper, and composite paper; non-woven fabric, cloth; plastic; metal such as copper and aluminum; bag-like and container-like (bottle-like, A box-shaped or cylindrical package) may be included, and the surface may be coated with polyethylene or the like. Specific examples include paper boxes filled and enclosed with solids, liquids, powders, etc., plastic cases, pouch bags, PET bottles, beverage cans, Ito cans, and integrated packages that package multiple items. Can be mentioned.

  FIG. 2 shows an example of a package with a hanger of the present invention. In FIG. 2, both ends of the hanger member 1 of the present invention are joined and fixed to the surface of the package 30 by the heat-sensitive resin layer 11 to form an adhesive portion 21, and the center of the hanger member 1 is carried around the package. It is used as a time suspension part 20 (lifter).

  Examples of the package 30 include a package exemplified as an adherend of the hanger member of the present invention. Typical examples of such a package 30 include synthetic paper whose surface is coated with plastic such as polyethylene, bags made of heat-resistant plastic, containers (bottles, boxes, cylindrical containers, etc.), and the like. Can be mentioned.

  Moreover, the hanger member 1 of this invention can endure the carrying of a heavy article. When the hanger member 1 is attached to a package, the hanger member 1 can be used for a long time even in various climatic conditions such as a cold region having a temperature of about −20 ° C. and a high temperature and humidity region having a temperature of 40 ° C. and a humidity of 90%. Can withstand the carrying of things. The above-mentioned characteristics of the hanger member 1 of the present invention include, for example, holding force, shearing force, vibration resistance, etc. at two bonding portions 21 having a bonding area of 20 mm × 50 mm when the package with a hanger shown in FIG. 2 is produced. Can be used as an index.

  As shown in FIG. 3, the holding force applies a constant load 40 to the package 30 (or encloses the load 40 in the package 30) and holds the hanging part 20 of the hanger member 1 as a latch member (support). It is expressed in a period in which the state suspended from the (member) 50 can be maintained. For example, when a load of 29.4 N (3 kgf) is applied, the hanger member 1 of the present invention maintains a suspended state for 90 days or more at a high temperature and high humidity with a temperature of 40 ° C. and a humidity of 90%, or at a low temperature of −20 ° C. It is also possible.

  The shearing force is expressed as a tensile shearing adhesive force (shearing force: unit N) at the bonding portion 21. More specifically, the shear force of a sample having an adhesion area of 15 mm × 10 mm was measured by a method according to JIS K 6850, and the shear force of the obtained sample corresponded to two bonded portions having an adhesion area of 20 mm × 50 mm. Convert to shear force. The hanger member 1 of the present invention has a shearing force (converted value) of 588 N (60 kgf) or more at a temperature of 40 ° C. and a humidity of 90% under high temperature and high humidity or at a temperature of −20 ° C. under a condition of a tensile speed of 1000 mm / min. It is also possible to demonstrate.

  As shown in FIG. 4, the vibration resistance is obtained when the hanger part 1 of the hanger member 1 fixed to the adherend is gripped and continuously swung in an arc at an angle of about 90 °. To the number of vibrations until the hanger member 1 is peeled off. The hanger member 1 of the present invention can exhibit vibration resistance of 300 times or more under conditions of normal temperature (25 ° C.) and humidity of 60% when, for example, a load of 29.4 N (3 kgf) is applied.

  The package with a hanger of the present invention can be formed, for example, by providing a step of joining a hanger member by the above-described method in a pre-process or a post-process in which an article is enclosed and filled in the package during the manufacturing process of the package. . The package with a hanger thus obtained can withstand carrying without being peeled even if a heavy object is enclosed.
