Abstract
The utility model discloses an easily tear packaging film, easily tear packaging film includes and is set gradually to easily tearing PET thin layer, aluminium foil layer, heat -seal layer in to by outer, all be provided with glue layer and together compound through the glue layer between layer and layer. The utility model discloses the utilization is easily torn exchanging of PET film and is torn the performance, including the good ductility of soft aluminium foil self, and the heat -seal layer makes for crowding the PE film altogether easily tear packaging film has good leakproofness and formability before not having the use, tear more easily when using.
Description
Technical field
The utility model relates to packaging film field, relates generally to one and easily tears packaging film.
Background technology
Composite package film is that society uses a kind of flexible packaging film comparatively widely.When consumer needs to use product, the packaging film of product will be torn.But the packaging film used on the market generally can be provided with opening and open to facilitate consumer, but present used packaging film generally all to there is tearing notch uneven, be even difficult to the problem of tearing, product used and causes very large impact.The packaging film of such as facial mask, the main foreigner tourists of consumption is women, and their hand strength is relatively little, once product is difficult to tear or tearing notch is uneven, all makes the experience of consumer on product cause bad impact.
Therefore, prior art has yet to be improved and developed.
Utility model content
In view of above-mentioned the deficiencies in the prior art, the purpose of this utility model is to provide one easily to tear packaging film, is intended to solve existing packaging film tearing notch uneven or be difficult to the problem of tearing.
The technical solution of the utility model is as follows:
One easily tears packaging film, and wherein, the described packaging film that easily tears comprises and sets gradually as easily tearing PET film layer, aluminium foil layer, hot sealing layer from outside to inside; Be provided with glue layer between the layers and be combined with each other by glue layer.
Described easily tears packaging film, and wherein, described glue layer is polyurethane adhesive water layer.
Described easily tears packaging film, and wherein, described hot sealing layer is co-extrusion PE thin layer.
Described easily tears packaging film, and wherein, the described thickness easily tearing PET film layer is 12 microns, and the thickness of described aluminium foil layer is 7 microns, the thickness of described hot sealing layer 65 ~ 110 microns.
Beneficial effect: one provided by the utility model easily tears packaging film, by easily tearing PET film layer, aluminium foil layer, co-extrusion PE thin layer dry type be composited, utilize the line easy-tear performance easily tearing PET film, and the PE film of improvement, make it easily tear, add the good ductility of soft aluminium foil self, hot sealing layer is multi-layer co-extruded PE film, make the described packaging film that easily tears before not using, there is good sealing and mouldability, more easily tear in use.
Accompanying drawing explanation
Fig. 1 is the structural representation easily tearing packaging film provided by the utility model.
Detailed description of the invention
The utility model provides one easily to tear packaging film, for making the purpose of this utility model, technical scheme and effect clearly, clearly, further describes below to the utility model.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
One provided by the utility model easily tears packaging film, and shown in composition graphs 1, the described packaging film that easily tears comprises and sets gradually as easily tearing PET film layer 1, aluminium foil layer 2, hot sealing layer 3 from outside to inside; Be provided with glue layer between the layers and be combined with each other by glue layer (not shown).
Wherein, ground floor from outside to inside adopts and easily tears PET (PETG) thin layer 1, easily tearing PET film is the comprehensive packing film of a kind of Performance comparision, its transparency is good, glossy, and has good air-tightness, its good mechanical performance, very power is good, dimensionally stable, is suitable for printing.Easily tear PET film and also there is excellent heat-resisting, cold resistance and good chemical proofing and oil resistivity.
The second layer adopts soft aluminium foil layer 2, and aluminium foil self has good ductility, is soft metallic film, not only has the advantages such as protection against the tide, airtight, shading, erosion resistant, guarantor be fragrant, nonpoisonous and tasteless, but also has metallic luster, make packaging film elegant in appearance.
Third layer is hot sealing layer, and hot sealing layer adopts co-extrusion PE (polyethylene) thin layer, ensures that heat sealability also guarantees the mechanical performance of PE film simultaneously, ensures the flatness of major requirement performance and the tearing notch easily torn.Preferably, the described thickness easily tearing PET film layer 1 can be 12 microns, and the thickness of described aluminium foil layer 2 can be 7 microns, and the thickness of described hot sealing layer 3 can be 65 ~ 110 microns.
Described glue layer is polyurethane adhesive water layer, and other polyurethane glue of food-grade selected by glue, ensures the use safety of packaging film.
Described preparation of easily tearing packaging film is by above-mentioned trilaminate material, and be composited by two-layer glue layer dry type, preparation method is simple.The packaging film that easily tears provided by the utility model, before product does not use, can ensure good sealing and mouldability, can easily tear, and tearing notch be neat during use.
Should be understood that; application of the present utility model is not limited to above-mentioned citing; for those of ordinary skills, can be improved according to the above description or convert, all these improve and convert the protection domain that all should belong to the utility model claims.
