Layer and the BOPP layers (BOPP on the second adhesive layer：Biaxially Oriented Polypropylene, biaxial tension
Polypropylene film).
Further, when sterilization temperature requirement is below 100 DEG C, the hot sealing layer uses CPE layers of (CPE：Chlorinated
Polyethylene, haloflex), when sterilization temperature requirement is more than 100 DEG C and is less than or equal to 130 DEG C, hot sealing layer is used
CPP layers of (CPP：CurrentPolypropylene, cast polypropylene).
Further, described BOPP layers is by the BOPP film after corona PROCESS FOR TREATMENT.
Further, described PVDC layers thickness is less than or equal to 18 microns.
Further, first adhesive layer is identical with the second adhesive layer structure, including the molten type of HT3135A esters
Type dry polyurethane composite adhesive and the molten type polyurethane composite dry adhesive of HT3135B esters, the molten type polyurethane of HT3135B esters are done
Formula composite adhesive is on the molten type polyurethane composite dry adhesive of HT3135A esters.
Compared with prior art, the beneficial effects of the utility model：
1st, the utility model uses PVDC layers, and barrier is high, and oxygen transit dose reaches 7.9cm3/m2.24h.atm, vapor
Transit dose reaches 1.6g/m2.24h.Using the structure of BOPP layers and PVDC layers cooperation, bonding strength is very big before and after boiling, nothing
Method is peeled off, and peeling force reaches 5N or so between PVDC layers and CPP layers.BOPP is colourless, odorless, tasteless, nontoxic, and with height
Tensile strength, impact strength, rigidity, obdurability and the good transparency.BOPP film has good printing to fit after sided corona treatment
Ying Xing, can obtain the appearance of fineness with chromaticity printing.
2nd, the molten type polyurethane composite dry adhesive of HT3135B esters and the molten type polyurethane dry type of HT3135A esters are composite adhered
Agent has good cohesive, makes that between each layer higher peel strength can be obtained, while having certain anti-medium and corrosion resistant
Corrosion, makes Stability Analysis of Structures between the phenomenon for being not susceptible between each layer come off, each film layer during long-term use, from
And ensure that the anti needling of the present embodiment.
3rd, the utility model mechanical performance, heat sealability are good, are applicable to a variety of package packing machinies；Flexible structure, can be with
Existing all plastic basis materials are combined；Chemical stability is good, acid and alkali resistance, salt, solvent resistant, oil strong, nontoxic to human body
It is harmless.The meat packed with the present embodiment normal temperature after thermophilic digestion (i.e. boiling 30 minutes at a temperature of 121 DEG C), which is preserved, to be protected
The matter phase was up to more than 6 months.
