Abstract
The utility model relates to a high temperature resistance cooking film made of PVDC laminated composite material. The middle layer of the film is made of multipolymer of vinvlidene chloride and chloroethylene; the two layers are conglutinated at two sides by adhesives; the adhesive is a solvent-free colloidal liquid with single-layer. The PVDC laminated composite material of the utility model can adopt solventless composite technique and solventless laminator to realize the recombination, thus the PVDC film need not be pretreated and can be directly composite, so as to reduce production process and cost. By adopting the high-temperature resistance solventless colloidal liquid adhesive, the film can bear above 121 DEG C of cooling temperature, thus the utility model can be wildly applied. In addition, the utility model has the advantages of being difficult to be broken off, no crack, good barrier performance with low cost, high transparency, being capable to show containing product to customer, providing convenience for customers to perchance, being capable of being heated by microwave and convenient for use.
Description
Technical field
The utility model relates to packaging films for food products, especially for a kind of be PVDC lamination complex fire resistant cooking food packaging film interlayer, that adopt lamination lining cement combination process method to make with the PVDC film.
Background technology
High-barrier transparent type digestion resistant food bag is badly in need of in Chinese food work.Meat product is the important channel of human panning protein, fat, mineral matter, account for more than 30% of human food's consumption expenditure, therefore meat product industry occupies the critical positions of food industry, meat product industry comprise butcher, the processing of refrigeration, various meat products, except that the edible raw meat of few kind and indivedual local people, most meat packing technologies can be divided under the normal pressure high temperature sterilization under the pasteurize and high pressure.The purpose of pasteurize is to kill enzyme and the virus that in the meat people is had pathogenic effects under the normal pressure, prevent the edible back of people food poisoning, make meat obtain shortening simultaneously, the purpose of high pressure-temperature sterilization is all bacteriums and the spore that kills in the meat, and adopt tight packing, stop bacteria live and breeding, prevent the meat product corruption, so cooked meat product must could be realized long term storage through high temperature high pressure sterilizing after packing.
Therefore, the packing that are used for the meat product of digestion resistant, anti-storage must possess following condition:
1, can bear boiling under 121 ℃ of temperature, heat 40 minutes, not deform inside and outside the packaging bag, heat-sealing place is not ftractureed, infiltration, interlayer do not separate, and mechanical strength, barrier do not reduce.
2, oxygen, water vapour, food flavor, flavoring fragrance etc. there is very high barrier.
3, mechanical strength is good, is applicable to that various package packing machine bag machineries use.
4, heat sealability is good, easily seals and very high heat seal strength arranged.
5, chemical inertness is good, with acid, alkali, salt, solvent, grease chemical reaction does not take place.
6, meet the food hygiene requirement, nontoxic to the people.
The flexible packaging field has only aluminum foil film just can reach this requirement at home at present, and outward appearance is beautiful, the rejection rate height, can bear thermophilic digestion more than 121 ℃, therefore obtain a large amount of the employing, but also have following shortcoming: the one, aluminium foil is fractureed by fold crackle to occur, the barrier forfeiture easily; The 2nd, opaque, the customer can't see inner package, inconvenient purchase of customer; The 3rd, can not use microwave heating; The 4th, price is higher.
The utility model content
The purpose of this utility model is to provide that a kind of vapour lock is good, the PVDC lamination complex fire resistant cooking food packaging film of transparent type digestion resistant.
For achieving the above object, the technical solution of the utility model is to have adopted a kind of PVDC lamination complex fire resistant cooking food packaging film, respectively by the two-layer adhesion of lining cement and both sides, described lining cement is the solvent-free colloidal liquid lining cement of individual layer to packaging film by the copolymer p VDC of interlayer vinylidene chloride and vinyl chloride.
Described food package film is from outside to inside being: the copolymer of mylar/solvent-free colloidal liquid lining cement/vinylidene chloride and vinyl chloride/solvent-free colloidal liquid lining cement/cast polypropylene film.
Described food package film is from outside to inside being: the copolymer of bidirectional stretching polypropylene film/solvent-free colloidal liquid lining cement/vinylidene chloride and vinyl chloride/solvent-free colloidal liquid lining cement/cast polypropylene film.
The thickness of each layer of packaging film cross section (μ m) is from outside to inside being followed successively by: light packing, 12/2/20/2/50; Heavily pack 12/2/20/2/70.
PVDC laminated composite structures of the present utility model can adopt solvent-free combination process and solvent-free composite machine to realize recombination process, thus the PVDC film do not need through pre-shrink to handle can be directly used in compoundly, reduce the technological process cost-cutting.Adopt heat-resistant solvent-free colloidal liquid lining cement can make food package film bear thermophilic digestion more than 121 ℃, thereby can large-scale popularization use.Simultaneously, use the PVDC film, the utility model is also had the following advantages: be not easy to fracture, do not go out crackle, good barrier property, low price; The diaphaneity height, the customer sees inner package, and purchase makes things convenient for customers; Can use microwave heating, easy to use.
Description of drawings
Fig. 1 is a cross section structure enlarged drawing of the present utility model.
The specific embodiment
As shown in Figure 1, of the present utility model is that the compound production of the digestion resistant food-film bag of interlayer need be carried out in two steps with PVDC: the first step, with BOPP or PET with PVDC is compound, thermalization is handled; Second step is compound with CPP and BOPP or PET/PVDC, finishes the complex film of BOPP or PET/PVDC/CPP.Among the figure, each sequence number is represented respectively: 1, outer PET or BOPP (polyester or bidirectional stretching polypropylene film), 2, the solvent-free colloidal liquid lining cement of individual layer (adh), 3, interlayer PVDC (copolymer of vinylidene chloride, vinyl chloride), 4, nexine CPP (cast polypropylene film)
Complex film cross section structure of the present utility model is:
PET(BOPP)/adh/PVDC/adh/CPP
Compound membrane bag product of the present utility model has the heavy packaging composite film bag of (the light packaging composite film bag of 0.5kg) and 0.5kg, and the optimal cross section thickness kind of product has:
