Abstract
A composite packaging film with a heat shrinkable property comprises a base material layer; a printing layer, a bonding layer and a heat-sealing layer cover the base material layer in sequence; the base material layer and the heat-sealing layer are films with the heat shrinkable property; the base material layer is a polyester film with the heat shrinkable property; the heat-sealing layer is a multi-layer coextrusion polyolefin film with the heat shrinkable property or an oriented polystyrene film with the heat shrinkable property. According to the composite packaging film, the forming condition of a packaging bag after vacuumizing and hot packaging of a commodity can be effectively improved, the bag breaking problem caused by vacuumizing is eliminated, and the composite packaging film has favorable flexibility and high impact resistance and high tear resistance, is not easy to break and damage, is insusceptible to water, and is high in shrinking percentage.
Description
Technical field
The utility model relates to a kind of improvement of plastic composite packaging film, especially a kind of multi-layer compound package film with thermal contraction function.
Background technology
Multi-layer compound package film develops comparatively fast at home, because it has exquisite printing effect, and outstanding physicochemical property, the cheap features such as price, are widely used in the fields such as food, medicine, chemical industry, machinery.Part commodity are because of its production technology restriction and requirement, must adopt the method that vacuumizes hot packing, after article are packaged into bag under hot state, vacuumize, to guarantee that in packaging bag, environment anaerobic is aseptic, prevent that commodity from qualitative change occurring in packaging bag, extends the shelf-life of commodity effectively.
Common multi-layer compound package film is basic shrinkage-void energy after carrying out MULTILAYER COMPOSITE, with the method package goods, when loaded article profile is irregular, is packaged in while vacuumizing and can produces distortion according to the shape of packing material, the lighter's packaging bag distortion, cannot see printed patterns and word clearly; Severe one packaging bag local pressure is excessive, and bag is pierced or breaks, the normal use of impact packing.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of heat-shrinkable composite package film, can effectively improve the shaping situation that commodity vacuumize hot packing packaging bag afterwards, stops the broken bag problem causing because vacuumizing.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of heat-shrinkable composite package film, comprise substrate layer, and on substrate layer, be coated with successively printed layers, bonding coat and hot sealing layer;
Substrate layer and hot sealing layer are the film with thermal contraction function.
Substrate layer is thermal contraction type mylar.
Hot sealing layer is multi-layer co-extruded polyolefine heat shrinking film or oriented polystyrene heat-shrinkable film.
The bonding coat of bonding coat for adopting polyurethane adhesive to make.
Between printed layers and hot sealing layer, by bonding coat, adopt the compound method of dry type bonding.
By client's requirement and product design demand, the material of substrate layer and hot sealing layer can realize independent assortment.
A kind of heat-shrinkable composite package film that the utility model provides, because substrate layer and hot sealing layer are all selected the film with thermal contraction function, guarantee that raw MAT'L film, through Compound Machining, functional while of enhanced package film, impels packaging film integral body still to have good thermal contraction performance.Vacuumize and in hot packing process, trigger packaging film thermal contraction function, make packaging film internally wrap article and produce active constraint effect, can effectively according to commodity shape, shrink bag article in laminating and shrink bag article in laminating according to interior bag contoured article, keep packaging bag overall performance, prevent from, because in-built article corner angle are sharp-pointed or the appearance of the too large bag shape distortion causing of vacuum action power or bag face disrepair phenomenon, effectively ensureing that the packing of commodity is respond well; Can effectively improve the shaping situation that commodity vacuumize packaging bag after hot packing, stop the broken bag problem that causes because vacuumizing, have good elasticity, impact resistance, tear resistance are strong, not cracky, be not afraid of tide, shrinkage percentage is large.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail:
Fig. 1 is the utility model structural representation.
The specific embodiment
As shown in Figure 1, the utility model comprises substrate layer 1, is coated with successively printed layers 2, bonding coat 3 and hot sealing layer 4 on substrate layer 1;
Substrate layer 1 and hot sealing layer 4 are for having the film of thermal contraction function.
Substrate layer 1 can select that diaphaneity is high, the thermal contraction type polyester of good barrier property (PET) film.
Hot sealing layer 4 can be selected multi-layer co-extruded polyolefin (POF) heat-shrinkable film or oriented polystyrene (OPS) heat-shrinkable film of high heat-sealing strength.
The bonding coat of bonding coat 3 for adopting polyurethane adhesive to make.
By intaglio press, printed layers 2 is printed on substrate layer 1, between printed layers 2 and hot sealing layer 4, by bonding coat 3, adopts the compound method of dry type bonding.
Claims (5)
