Abstract
The utility model discloses a kind of solvent-free composite cover material film, comprise hot sealing layer, wherein, described hot sealing layer is also provided with one deck upper epidermis, is composited by glue layer between described upper epidermis and hot sealing layer.The utility model, by improving existing lid material film unsymmetric structure, is formed by glue layer is once-combined by multi-layer co-extruded thin layer and upper epidermis, and its processing technology is simple, and film loss is little, and productive costs is low; And the mode printed in employing makes ink avoid and food and extraneous contact, reduce the phenomenon that ink comes off, ensure that edible safety; In addition, upper epidermis has good mechanical property, guarantees that product crimp can not occur, to obtain good experience.Solve very well existing lid material film easily curling, printing ink hold caducous technical matters.
Description
Technical field
The utility model relates to packing field, particularly relates to a kind of solvent-free composite cover material film in the packing of product.
Background technology
Lid material film is again capping film, easily takes off film, is the packing being widely used in food, beverage and medical field.Lid material film great majority are complex film, are formed by two-layer different materials coextru-lamination.Widely used is at present exactly the multi-layer co-extruded film of barrier, but, because multi-layer co-extruded film is mostly unsymmetric structure as the structure of lid material film, easily causes product curling, affect appearance; And this lid material film can only adopt the mode of surface printing to carry out printed patterns, in transport and handling process, easily cause ink to come off, have a strong impact on the outward appearance of product, reduce the class of product.Therefore be further improved and develop.
Utility model content
The purpose of this utility model is to provide a kind of solvent-free composite cover material film, with solve existing lid material film easily curling, printing ink hold caducous technical matters.
Technical scheme designed by the utility model is as follows:
A kind of solvent-free composite cover material film, is comprised hot sealing layer, wherein, described hot sealing layer is also provided with one deck upper epidermis, is composited between described upper epidermis and hot sealing layer by glue layer.
Described solvent-free composite cover material film, wherein, described upper epidermis is set to BOPET film layer, and thickness is set to 12 microns.
Described solvent-free composite cover material film, wherein, described upper epidermis is set to BOPP thin layer, and thickness is set to 18 microns.
Described solvent-free composite cover material film, wherein, described upper epidermis is set to BOPA thin layer, and thickness is set to 15 microns.
Described solvent-free composite cover material film, wherein, described hot sealing layer is multi-layer co-extruded thin layer.
Described solvent-free composite cover material film, wherein, ink layer is arranged between upper epidermis and hot sealing layer.
Described solvent-free composite cover material film, wherein, described glue layer is set to solventless adhesive layer.
The utility model, by improving existing lid material film, is formed by glue layer is once-combined by multi-layer co-extruded thin layer and upper epidermis, and its processing technology is simple, and film loss is little, and productive costs is low; And the mode printed in employing makes ink avoid and food and extraneous contact, reduce the phenomenon that ink comes off, ensure that edible safety; In addition, upper epidermis has good mechanical property, guarantees that product crimp can not occur, to obtain good experience.Solve very well existing lid material film easily curling, printing ink hold caducous technical matters.
Accompanying drawing explanation
Fig. 1 is the structural representation of solvent-free composite cover material film of the present utility model.
Detailed description of the invention
For making the purpose of this utility model, technical scheme and advantage clearly, clearly, developing simultaneously referring to accompanying drawing, the utility model is described in further detail for embodiment.
The utility model discloses a kind of solvent-free composite cover material film, is the packaging seal material being widely used in food, beverage and medical field.This solvent-free composite cover material film comprises hot sealing layer, and this hot sealing layer is set to multi-layer co-extruded film 1, and preferably, this multi-layer co-extruded thin layer 1 is set to three-layer co-extruded film, by blowing up explained hereafter gained.Wherein, based on multi-layer co-extruded thin layer 1, be provided with one deck upper epidermis 2 thereon, be composited by glue layer 3 between this upper epidermis 2 and multi-layer co-extruded thin layer 1.
Preferably, this upper epidermis 2 can adopt the one in BOPET film layer (biaxially oriented polyester film), BOPP thin layer (bidirectional stretching polypropylene film), BOPA thin layer (BON biaxially oriented nylon film) three.BOPET film, BOPP film and BOPA film three all have good mechanical property, and its rigidity and barrier are strong, good toughness; But also be excellent printing material, exquisite pattern can be printed out, color glow; Again and, the utility model adopt in print mode print product pattern, ink and food, the external world are separated, both avoided the embarrassment that ink comes off, the edible safety of the food ensured again, kills two birds with one stone.
Preferably, when upper epidermis 2 adopts BOPET film layer, its thickness is set to 12 microns; When adopting BOPP thin layer, its thickness is set to 18 microns; When adopting BOPA thin layer, its thickness is set to 15 microns.
Preferably, in order to ensure food consumption safety, avoid coming off of ink, this solvent-free composite cover material film also comprises ink layer (not shown), and ink layer is arranged between upper epidermis and hot sealing layer.
Preferably, this solvent-free composite cover material film adopts solventless adhesive layer as glue layer 3.
The utility model, by improving existing lid material film unsymmetric structure, is formed by glue layer 3 is once-combined by multi-layer co-extruded thin layer 1 and upper epidermis 2, and its processing technology is simple, and film loss is little, and productive costs is low; And the mode printed in employing makes ink avoid and food and extraneous contact, reduce the phenomenon that ink comes off, ensure that edible safety; In addition, upper epidermis 2 has good mechanical property, guarantees that product crimp can not occur, to obtain good experience.Solve very well existing lid material film easily curling, printing ink hold caducous technical matters.
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 be converted; such as; to the replacement etc. of the connection mode of each several part in the utility model, all these improve and convert the protection domain that all should belong to the utility model claims.
