Abstract
The invention discloses a high-temperature-resistant cooking bag which sequentially comprises a casting polypropylene film layer, a polyimide film layer, a polytetrafluoroethylene film layer, a silicon coating and a printing layer from inside to outside. The casting polypropylene film layer and the polyimide film layer are connected through a nano adhesive, and the polyimide film layer and the polytetrafluoroethylene film layer are connected through a nano adhesive. The silicon coating is obtained by directly coating silicon powder on the polytetrafluoroethylene film layer. The printing layer is obtained by printing a pattern on the silicon coating through polyurethane printing ink. According to the high-temperature-resistant cooking bag, raw materials of special structures and with extremely good high-temperature-resistant effect, the adhesives high in isolation performance and the printing ink not prone to falling and permeating are adopted, so that the cooking bag has the advantages of being resistant to high temperature, free of deformation, high in isolation performance, free of permeability, lasting, free of ink falling, healthy and safe, and is suitable for being used during high-temperature cooking.
Description
Technical field
The present invention relates to packaging bag manufacture field, be specifically related to a kind of digestion resistant bag.
Background technology
Retort pouch refers to and can be used for packaged food, medical apparatus etc. and the laminated film that can stand high-temperature steam (more than 100 DEG C) the pasteurization packaging bag of making, and also claiming can the flexible package of boiling or foods packed in carton containers.Retort pouch food, compared with canned food, uses flexible packages, imposes not aeriferous reserved capacity vacuum packaging, form compact and thinner packaged configuration, its heat transfer is fast, can reach bactericidal effect at short notice, thus become the main trend of 21st century food industry packaging bag, but, current retort pouch still also exists some drawback, as: heat resistance is good not, barrier is poor, ink easily drops enters food, etc., these all constrain the development of retort pouch, must be improved.Invention describes a kind of digestion resistant bag, the adhesive of its former material adopting special structure, high-temperature resistant result fabulous, high barrier and the ink not easily dropping and permeate, make retort pouch have high temperature resistant indeformable, high-barrier is impermeable, persistence does not fall ink, healthy and safe advantage, be applicable to thermophilic digestion use.
Summary of the invention
For the deficiencies in the prior art, the object of the present invention is to provide a kind of digestion resistant bag.
The technical problem that the present invention solves can realize by the following technical solutions: a kind of digestion resistant bag, comprise successively from inside to outside: cast polypropylene film layer, polyimide film layer, polytetrafluoroethylene film layer, silicon coating and printed layers, described cast polypropylene film layer is all connected by nanometer binder with polytetrafluoroethylene film layer with polyimide film layer, polyimide film layer, described silicon coating is directly spread upon on polytetrafluoroethylene film layer by silica flour and obtains, and described printed layers obtains by using polyurethane ink printed patterns on silicon coating.
Preferably, described nanometer binder is made up of following raw material: nanometer couplant 3wt%-7wt%, containing BPF epoxy resin 5wt%-10wt%, polyurethane binder 82wt%-92wt% of two fragrant A.
Preferably, be added with curing agent in described polyurethane ink, the percentage of described curing agent shared by polyurethane ink is 1.5wt%-3wt%.
Beneficial effect is: the present invention is a kind of digestion resistant bag, the adhesive of its former material adopting special structure, high-temperature resistant result fabulous, high barrier and the ink not easily dropping and permeate, make retort pouch have high temperature resistant indeformable, high-barrier is impermeable, persistence does not fall ink, healthy and safe advantage, be applicable to thermophilic digestion use.
Detailed description of the invention
The following detailed description of the preferred embodiment of the present invention.
The detailed description of the invention of a kind of digestion resistant of the present invention bag: a kind of digestion resistant bag, comprise successively from inside to outside: cast polypropylene film layer, polyimide film layer, polytetrafluoroethylene film layer, silicon coating and printed layers, described cast polypropylene film layer is all connected by nanometer binder with polytetrafluoroethylene film layer with polyimide film layer, polyimide film layer, described silicon coating is directly spread upon on polytetrafluoroethylene film layer by silica flour and obtains, and described printed layers obtains by using polyurethane ink printed patterns on silicon coating.Described nanometer binder is made up of following raw material: nanometer couplant 3wt%-7wt%, containing BPF epoxy resin 5wt%-10wt%, polyurethane binder 82wt%-92wt% of two fragrant A.Be added with curing agent in described polyurethane ink, the percentage of described curing agent shared by polyurethane ink is 1.5wt%-3wt%.
After above-mentioned processing step, obtain digestion resistant bag, the adhesive of its former material adopting special structure, high-temperature resistant result fabulous, high barrier and the ink not easily dropping and permeate, make retort pouch have high temperature resistant indeformable, high-barrier is impermeable, persistence does not fall ink, healthy and safe advantage, be applicable to thermophilic digestion use.
The foregoing is only embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every utilize description of the present invention to do equivalent structure or the conversion of equivalent flow process, or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
