Abstract
The utility model provides a degradable plastic film, which comprises a double-layer high-strength starch composite film and a reinforced layer clamped between the high-strength starch composite films; the outer sides of the high-strength starch composite films are respectively provided with a layer of light-gathering film; a layer of heat stable film is respectively arranged on the outer sides of the light-gathering films; and one antibacterial layer is arranged on the outer side of one of the heat-stable films. The utility model discloses a degradable plastic film, the antibiotic layer that titanium dioxide layer formed plays the effect of killing inside by the plastic film, the microorganism on the food that is wrapped up by the plastic film promptly through photocatalysis. Meanwhile, organic matters in the residual pesticide can be degraded through photocatalysis; the light-gathering film can gather the light source to react on the high-strength starch composite film through light gathering, and meanwhile, the high-strength starch composite film is guaranteed to be degraded only after the service life of the plastic film, so that the reliability is improved.
Description
Technical Field
The utility model relates to a plastic film, concretely relates to degradable plastic film.
Background
Films made from polyvinyl chloride, polyethylene, polypropylene, polystyrene, and other resins are used for packaging, and as a film coating. Plastic packages and plastic package products have a larger share in the market, and particularly, composite plastic flexible packages are widely applied to the fields of food, medicine, chemical industry and the like, wherein the proportion of the plastic packages is the largest, such as beverage packages, quick-frozen food packages, steamed and cooked food packages, fast food packages and the like, and the plastic packages and the plastic package products bring great convenience to the life of people. Plastic films are most widely used in the packaging field. The plastic film can be used for food packaging, electric appliance product packaging, daily necessity packaging, clothing packaging and the like. However, the existing plastic film has certain defects in the using process, the plastic film has low strength and is easy to damage in the using process, the damaged plastic film has high recycling difficulty, the production cost is increased, the used plastic film is difficult to degrade, severe white pollution is caused to the environment, the natural environment is harmed, and the ecological development of natural organisms is realized.
Disclosure of Invention
In order to solve the problem, the utility model provides a degradable plastic film.
The technical scheme of the utility model is that: a degradable plastic film comprises a double-layer high-strength starch composite film and a reinforcing layer clamped between the high-strength starch composite films; the outer sides of the high-strength starch composite films are respectively provided with a layer of light-gathering film; a layer of heat stable film is respectively arranged on the outer sides of the light-gathering films; and one antibacterial layer is arranged on the outer side of one of the heat-stable films.
Further, the reinforcing layer is a cross-shaped net structure made of SA/PVA degradable composite materials.
Further, the antibacterial layer is a titanium dioxide layer.
Furthermore, the reinforcing layer, the light-gathering film, the heat-stable film, the high-strength starch composite film and the antibacterial layer are adhered together by adopting polyolefin ADMER adhesive.
Further, the thickness of the antibacterial layer is 0.1 to 0.5 microns.
Advantageous effects
The utility model discloses a degradable plastic film, the antibiotic layer that titanium dioxide layer formed plays the effect of killing inside by the plastic film, the microorganism on the food that is wrapped up by the plastic film promptly through photocatalysis. Meanwhile, organic matters in the residual pesticide can be degraded through photocatalysis; the light-gathering film can gather the light source to react on the high-strength starch composite film through light gathering, and meanwhile, the high-strength starch composite film is guaranteed to be degraded only after the service life of the plastic film, so that the reliability is improved.
