Abstract
The present invention discloses a high-temperature casing film. The packaging film is a five-layer complex structure formed by a PET film layer 1, an anti-bacterial chemical coating 2, a TGPA layer 3, an anti-bacterial chemical coating 2 and a polymeric layer 4 from the outer side to the inner side. The high-temperature casing film has beneficial effects of simple structure and high practicality.
Description
Technical field
The present invention relates to packaging material application, particularly a kind of high temperature casing film.
Background technology
The high temperature casing film used at present, great majority are polyvinylidene chloride (PVDC), 121 DEG C of high-temperature sterilization treatment can be carried out, meet the sterilization needs of packaging high temperature meat product, but PVDC plastic casing film in order to needs attractive in appearance painted, color masterbatch composition in painted is EVA, toner and auxiliary agent, wherein contain a small amount of heavy metal in toner, when high temperature 121 DEG C of boilings, have migration, and this casing film is generally individual layer, direct Food Contact, these heavy metals can directly migrate to packaged food unavoidably, cause human injury.
Summary of the invention
The object of the invention is to solve the problem, devising a kind of high temperature casing film.
Realizing above-mentioned purpose technical scheme of the present invention is, a kind of high temperature casing film, the structure of this packaging film is respectively five layers of composite construction of PET film layer 1, fungi-proofing chemical reagent coating 2, TGPA layer 3, fungi-proofing chemical reagent coating 2 and polymeric layer 4 formation from outside to inside.
Described fungi-proofing chemical reagent coating 2 to be carried out the chemical reagent of highly adhering with adjacent layer and to have fungi-proofing function.
Described TGPA layer 3 is barrier layer.
Described PET film layer 1 is the modified poly ester layer of ethylene glycol, and shrinkage factor can reach more than 60%.
Described polymeric layer 5 is made for polypropylene or polypropylene miser, has highly shrinkable and can be high temperature resistant.
Utilize the high temperature casing film that technical scheme of the present invention makes, beneficial effect is high temperature resistant, can not when thermophilic digestion, and the heavy metal substance in painted moves and affects the security of packaged food.
Accompanying drawing explanation
Fig. 1 is the structural representation of high temperature casing film of the present invention;
In figure, 1, PET film layer; 2, fungi-proofing chemical reagent coating; 3, TGPA layer; 4, polymeric layer.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is specifically described, as the structural representation that Fig. 1 is high temperature casing film of the present invention, a kind of high temperature casing film, the structure of this packaging film is respectively five layers of composite construction of PET film layer, fungi-proofing chemical reagent coating, TGPA layer, fungi-proofing chemical reagent coating and polymeric layer formation from outside to inside; Described fungi-proofing chemical reagent coating 2 to be carried out the chemical reagent of highly adhering with adjacent layer and to have fungi-proofing function; Described TGPA layer 3 is barrier layer; Described PET film layer 3 is the modified poly ester layer of ethylene glycol, and shrinkage factor can reach more than 60%; Described polymeric layer 5 is made for polypropylene or polypropylene miser, has highly shrinkable and can be high temperature resistant.
The feature of the present embodiment is, the structure of this packaging film is respectively five layers of composite construction of PET film layer, fungi-proofing chemical reagent coating, TGPA layer, fungi-proofing chemical reagent coating and polymeric layer formation from outside to inside.Gas and the vapor permeability of PET film layer are low, namely excellent choke, water, oil and peculiar smell performance is had, fungi-proofing chemical reagent coating has efficient antibacterial effect, TGPA rete distinguishing feature has fabulous barrier and fabulous processability to gas, the transparency, glossiness, mechanical strength, retractility, wearability, cold resistance and surface strength are all very excellent in addition, polymeric layer has adhesiveness, this just makes the lower surface of polymeric layer can stick on the surface of packing material, decrease the air in packaging bag, improve antiseptic effect.
Technique scheme only embodies the optimal technical scheme of technical solution of the present invention, and those skilled in the art all embody principle of the present invention to some variations that wherein some part may be made, and belong within protection scope of the present invention.
