Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

In the first embodiment, as shown in the attached figures 1, 2, 3 and 6, an external control type bacteriostatic and mildewproof preservative bag adopts a bacteriostatic and mildewproof preservative carrier to adsorb food-grade ethanol (edible alcohol) or adsorb a bacteriostatic and mildewproof preservative (patent No. 202010101543.8). The surfaces of two sides of the outer wrapping film of the adsorption carrier of the external control type bacteriostatic mildew-proof freshness protection package are covered with the densely distributed evaporation air holes, and the evaporated and diffused gaseous ethanol or the bacteriostatic mildew-proof freshness protection agent can form a barrier and a gas protection layer in a packaging bag of food and adsorbed on the food, so that the food is particularly suitable for keeping moisture of the food, can keep the food moist and is close to the optimal state of just production, and can sterilize and inhibit propagation to prevent generation of mildew. The food has good taste and safety.

In this embodiment, the adsorption carrier of the bacteriostatic, mildewproof and freshness-retaining pack is a pure cotton spunlace cotton outer wrapping film, and the surfaces of both sides of the outer wrapping film are covered with densely-distributed evaporation and air diffusion holes.

Example two: an external control type antibacterial and mildewproof fresh-keeping bag is shown in figure 1, figure 2, figure 4 and figure 5, and adopts antibacterial and mildewproof fresh-keeping agent carrier to adsorb food grade ethanol (edible alcohol) or adsorb an antibacterial and mildewproof fresh-keeping agent (patent No. 202010101543.8). The surface of one side of the outer wrapping film of the adsorption carrier of the external control type bacteriostatic mildew-proof fresh-keeping bag is covered with densely distributed evaporation air holes, the preservative with gas evaporated and diffused on one side or bacteriostatic mildew-proof fresh-keeping agent can form a barrier and a gas protective layer in the packaging bag of food and adsorbed on the food, and the other side is not covered with densely distributed evaporation air holes and directly contacts the food. Food intended to retain moisture can keep the food moist, close to the optimum state immediately after production, and can sterilize, inhibit propagation and prevent the generation of mold. The food has good taste and safety. The method is particularly suitable for preventing the excessive residual quantity of the ethanol evaporated and diffused on the food contact surface of the external control type antibacterial mildew-proof fresh-keeping bag from influencing the food taste.

In this embodiment, the adsorption carrier of the bacteriostatic, mildewproof and freshness-retaining pack is a pure cotton spunlace cotton outer wrapping film, and one side surface of the outer wrapping film is covered with densely-distributed evaporation and air diffusion holes.

Example three: the difference between the embodiment and the embodiment I is that an external control type bacteriostatic and mildewproof preservative bag is shown in attached figures 3, 7, 8, 9, 10 and 11, and food grade ethanol (edible alcohol) is adsorbed by a bacteriostatic and mildewproof preservative carrier or a bacteriostatic and mildewproof preservative is adsorbed by the bacteriostatic and mildewproof preservative carrier (patent No. 202010101543.8). The surface of the outer wrapping film of the adsorption carrier of the external control type antibacterial mildew-proof fresh-keeping bag is not covered with densely distributed evaporation air holes.

As shown in figure 11, the surface layer adopts a PET plastic film (namely, a plastic film 1), the middle layer adopts long fiber cotton (namely, a fiber cotton layer 2), the bottom layer adopts breathable perforated PE (namely, a breathable layer 3), the continuous bag production mode is shown in figure 10, the existing perforation bag throwing operation of figure 11 is adopted, holes are perforated on an upper group of densely-distributed needle rollers 9 and a lower group of densely-distributed needle rollers 9 on a bag throwing machine, so that the surface of an outer wrapping film layer 7 is provided with the emitting holes 6, and then the outer wrapping film layer is thrown into a food packaging bag. The surface of the densely distributed card roller 9 is provided with a protective glue layer 10.

At least one side surface of the outer coating layer 7 of the bacteriostatic mildew-proof agent adsorption carrier layer 8 is covered with a dense porous breathable layer or an outer layer non-dense porous layer fiber composite membrane;

outer no close cloth poroma layer fibre complex film that breathes freely includes plastic film 1, the cotton layer 2 of fibre and ventilative layer 3, and the cotton layer 2 of fibre is located plastic film 1 and ventilative layer 3 between, and ventilative layer 3 is the ventilated membrane or the close film that punches.

The inside carrier storehouse 5 in being the package of adventitia layer 7, carrier storehouse 5 is filled in the package to antibacterial mould proof agent material absorption carrier layer 8, forms the seal limit 4 after the side seal of adventitia layer 7.

The preservative which evaporates and emits gaseous ethanol on two sides or inhibits bacteria and mildew can form a barrier and a gas protective layer in a packaging bag of food and adsorbed on the food, the food which wants to keep moisture can keep the food moist, is close to the optimal state of just production, and can sterilize, inhibit propagation and prevent the generation of mildew. The food has good taste and safety.

In this embodiment, the adsorption carrier of the external control type antibacterial and mildewproof freshness protection package is pure cotton spunlace cotton material, and the film surfaces on both sides of the external package are not covered with the evaporation air holes, so that the storage time of the external control type antibacterial and mildewproof freshness protection package can be prolonged.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the utility model, the scope of which is defined in the appended claims and their equivalents.
