Abstract
The present invention relates to a kind of degradable food product packing film, it is made up of the raw material of following parts by weight：38 45 parts of polyvinyl alcohol, 25 35 parts of PLA, 20 30 parts of chitosan, 14 21 parts of starch, 5 10 parts of cotton fibriia, 48 parts of kaolin, 25 parts of antiseptic, 14 parts of light stabilizer.The food package film of the present invention, obtains by base-material composite of polyvinyl alcohol, PLA and chitosan, has good mechanical performance and barrier property, safe and non-toxic degradable；Chitosan and Tea Polyphenols have good bacteriostasis, especially more preferable to staphylococcus aureus and Escherichia coli inhibition；Light stabilizer is added in the present invention, extends the service life of food product packing film；The present invention can improve the white pollution problems of getting worse, mitigate the pressure to caused by environment, meet the requirement built a resource-conserving and environment-friendly society.
Description
Technical field
The invention belongs to plastic sheeting technical field, and in particular to a kind of degradable food product packing film.
Background technology
Plastics are a kind of good high polymer materials of plasticity, use it for packaging field, with traditional packaging material
(paper, metal, glass etc.) is compared, and plastic package material has its unique performance.Each based packaging material being made of plastics, such as mould
Expect film, polybag, Plastic Drum and chest, plastic bottle and tank and compound package material etc., be widely used in food packaging applications,
For protecting commodity in the processes of circulation such as accumulating, sale, consumption not by various unfavorable conditions and environmental disruption and influence, lifting
The use value of commodity, market are in rising trend year by year to packaging material demand.Why plastic package material can be extensive
Using in packaging for foodstuff, being that its unique good characteristic is housed because of plastic bag, such as excellent physical and mechanical property, good change
Stability is learned, light, processing forming is good, good appearance, easily coloring etc..But the wholesomeness of some plastic materials
Can be poor, while its packaging waste can produce large effect to environment again, so as to have impact on plastic package material some
The use of food packaging applications.
With the increasingly raising of people's economic level and living standard, increasing consumer is pursuing spirit level not
While disconnected rising, influence of the aspect of material to its quality of life is focused more on." bread is the staff of life ", daily life be the mankind just
The important component often lived, and concern the deciding factor of human health survival and development.In face of the white of getting worse
Color pollution problem, non-degradable material is difficult to the processing that is degraded in the environment, therefore turns into solid waste, so that environment is seriously dirty
Dye.Consider factors, searching is a kind of degradable, white pollution will not be caused to environment, and meet food security and food
The degradation material of product packaging safety standard is an extremely urgent task.
The content of the invention
It is an object of the invention to provide a kind of degradable food product packing film,.
In order to realize the purpose of the present invention, adopt the following technical scheme that：
A kind of degradable food product packing film, is made up of the raw material of following parts by weight：
Preferably, degradable food product packing film is made up of the raw material of following parts by weight：
Preferably, starch is potato starch.
Preferably, antiseptic is Tea Polyphenols.
Preferably, light stabilizer is titanium oxide.
Beneficial effects of the present invention：
The food package film of the present invention, is obtained by base-material composite of polyvinyl alcohol, PLA and chitosan, is had good
Good mechanical performance and barrier property, it is safe and non-toxic degradable；Chitosan and Tea Polyphenols have good bacteriostasis, especially right
Staphylococcus aureus and Escherichia coli inhibition are more preferable；Light stabilizer is added in the present invention, extends food product packing film
Service life；The present invention can improve the white pollution problems of getting worse, mitigate the pressure to caused by environment, meet construction money
Source economizing type, the requirement of friendly environment society.
