Abstract
The invention discloses a microwave double-heating shrinkable packaging film. The film has a five-layer composite structure, which comprises the following layers from outside to inner side: a GSPET film 1, a STIE film 2, a TGPA film 3, a STIE film 2 and a TPP film 4. The invention has the beneficial effects of simple structure and good practicality.
Description
Technical field
The present invention relates to packaging material application, particularly the collapsible packaging film of a kind of microwave post bake.
Background technology
Current microwave post bake, most mechanical performance by using electron-beam accelerator to improve heat shrink films have been come, but have been too increased cost, and added procedure of processing, also reduce production efficiency.In addition, if when use electron-beam accelerator irradiates the heat shrink films with oxidation prevention layer, the composition generation oxidation of oxidation prevention layer also can be made to present yellow, also have impact on the exterior quality of heat shrink films.
Summary of the invention
The object of the invention is to solve the problem, devising the collapsible packaging film of a kind of microwave post bake.
Realizing above-mentioned purpose technical scheme of the present invention is, the collapsible packaging film of a kind of microwave post bake, the structure of this packaging film is respectively five layers of composite construction of GSPET rete 1, STIE rete 2, TGPA rete 3, STIE rete 2 and TPP rete 4 formation from outside to inside.
Described GSPET rete 1 is mylar, is be polymerized blended forming by various kinds of resin, has highly shrinkable and can be high temperature resistant more than 150 degree.
Described STIE rete 2 to carry out the chemical reagent of highly adhering with adjacent layer and to have fungi-proofing function.
Described TGPA rete 3 has high barrier.
Described TPP rete 4 is the co-polypropylene resin of modification.
The collapsible packaging film of microwave post bake utilizing technical scheme of the present invention to make, beneficial effect is reduction of cost, decreases procedure of processing, decreases the degree of oxidation, improves product appearance quality.
Accompanying drawing explanation
Fig. 1 is the structural representation of the collapsible packaging film of microwave post bake of the present invention; In figure, 1, GSPET rete; 2, STIE rete; 3, TGPA rete; 4, TPP rete.
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 the collapsible packaging film of microwave post bake of the present invention, the collapsible packaging film of a kind of microwave post bake, the structure of this packaging film is respectively five layers of composite construction of GSPET rete, STIE rete, TGPA rete, STIE rete and TPP rete formation from outside to inside; Described GSPET rete is mylar, is to be polymerized blended forming by various kinds of resin, has highly shrinkable and can be high temperature resistant more than 150 degree; Described STIE rete to carry out the chemical reagent of highly adhering with adjacent layer and to have fungi-proofing function; Described TGPA rete has high barrier; Described TPP rete is the co-polypropylene resin of modification.
The feature of the present embodiment is, the structure of this packaging film is respectively five layers of composite construction of GSPET rete, STIE rete, TGPA rete, STIE rete and TPP rete formation from outside to inside.GSPET rete improves shrinkage, reduce the fragility of packaging material, toughness also increases, and be easy to machine-shaping, surface smoothness is high, there is the good transparency, enhance heat-resisting quantity, the intensity of STIE rete is high, bonding force jail, wrinkle resistant, improve heat resistance, enhance cold tolerance, TGPA rete is at any temperature or damp condition, have remarkable obstruct steam concurrently, oxygen, the ability of smell and fragrance, TPP layer has heat-resisting quantity, reduce envelope temperature, heat-sealing firmness is not affected when there being dirt yet, improve the surface smoothness of goods, brightness and transparency, convergent force and shrinkage factor are improved, toughness and pliability are changed.
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.
