Embodiment 1

[0021] An environmentally friendly food plastic film, comprising the following components by weight:

[0022] 30 parts of linear low density polyethylene;

[0023] 20 parts of polyvinyl alcohol resin;

[0024] 5 parts of titanium stearate;

[0025] Chitosan 1 part;

[0026] 0.4 parts of nitrite;

[0027] Sodium fatty acid 0.1 part;

[0028] Glycerin 1 part.

[0029] The beneficial effects of the invention are: using linear low-density polyethylene and resin as main raw materials, and adding an appropriate amount of additives, not only ensures the strength and toughness of the plastic packaging bag, but also has a good degradation effect and reduces the impact on the surrounding environment.

Embodiment 2

[0031] An environmentally friendly food plastic film, comprising the following components by weight:

[0032] 40 parts of linear low density polyethylene;

[0033] 25 parts of polyvinyl alcohol resin;

[0034] 7 parts of titanium stearate;

[0035] 3 parts chitosan;

[0036] 0.6 parts of sulfur dioxide;

[0037] Sodium fatty acid 0.25 part;

[0038] Glycerin 2 parts.

[0039] The beneficial effects of the invention are: using linear low-density polyethylene and resin as main raw materials, and adding an appropriate amount of additives, not only ensures the strength and toughness of the plastic packaging bag, but also has a good degradation effect and reduces the impact on the surrounding environment.

Embodiment 3

[0041] An environmentally friendly food plastic film, comprising the following components by weight:

[0042] 50 parts of linear low density polyethylene;

[0043] 30 parts of polyvinyl alcohol resin;

[0044] 10 parts of titanium stearate;

[0045] Chitosan 5 parts;

[0046] 0.8 parts of nitrite;

[0047] Sodium fatty acid 0.4 parts;

[0048] 3 parts of glycerin.

[0049] The beneficial effects of the invention are: using linear low-density polyethylene and resin as main raw materials, and adding an appropriate amount of additives, not only ensures the strength and toughness of the plastic packaging bag, but also has a good degradation effect and reduces the impact on the surrounding environment.

Abstract

The present invention discloses an environmentally friendly food plastic film, which comprises, by weight, 30-50 parts of linear low-density polyethylene, 20-30 parts of a resin, 5-10 parts of titanium stearate, 1-5 parts of chitosan, 0.4-0.8 part of a preservative, and 0.1-0.4 part of a surfactant. According to the present invention, the linear low density polyethylene and the resin are adopted as the main raw materials, and a proper amount of the additive is added, such that the strong toughness of the plastic packaging bag is ensured, the good degradation effect is provided, and the influence on the surrounding environment is reduced.

Description

technical field [0001] The invention relates to a plastic film, in particular to an environment-friendly food plastic film. Background technique [0002] At present, plastic packaging bags have become an indispensable necessity in daily life, and they are also consumables. A large amount of plastic packaging bags are consumed every year. Plastic packaging bags are polymer compounds made of monomers as raw materials through addition polymerization or polycondensation reactions. They are generally made of synthetic resins and additives such as fillers, plasticizers, stabilizers, lubricants, and colorants. In people's daily life, plastic packaging bags are widely used, but the "white pollution" caused by waste plastics is becoming more and more serious. With the enhancement of people's awareness of environmental protection, how to alleviate white pollution has become a topic of increasing concern. Degradable plastic packaging bag is an emerging plastic product in recent years...
