Abstract
The invention discloses a kind of packaging bags with degradability, including polyvinyl alcohol, lubricant, filler, dicarboxylic acid ethyl ester, plasticizer and calcium carbonate.The beneficial effects of the present invention are: when being embedded in rubbish or soil after being combined as main component with other ingredients using polyvinyl alcohol, degradation effect is clearly, it is added to lubricant and Paris white, the tensile strength of these adding ingredients meeting reinforced plastics strap reduces its breathable moisture permeability, so that plastic packaging bag is kept original characteristic, is conducive to the popularization and application of degradative plastics packaging bag.
Description
Technical field
The present invention relates to a kind of packaging bag more particularly to a kind of packaging bags with degradability.
Background technique
Plastic packaging bag be using monomer as raw material, by high-molecular compound made of addition polymerization or polycondensation polymerized, it
Generally it is made by the additives such as synthetic resin and filler, plasticizer, stabilizer, lubricant, colorant.In the daily life of people
In work, plastic packaging bag is very widely used, but waste plastic bring " white pollution " is also increasingly severe.With people
Environmental consciousness enhancing, how to alleviate the topic that white pollution has been people's growing interest.Degradative plastics packaging bag is close
Emerging a kind of plastic products over year, its properties can meet requirement and have the performance in storage life constant
Characteristic, and the substance of environmental sound can be degraded under natural environmental condition after.
Although currently, occur various degradative plastics packaging bags on the market, experiments have shown that: most of degradations
Plastic packaging bag starts thinning, weightless, intensity decline after generally exposing 3 months in the environment, gradually splinter, if these
Fragment is embedded in rubbish or soil, then degradation effect is unobvious.In addition, some adding ingredients in degradative plastics can change modeling
Certain characteristics of material, such as breathable moisture permeability increases, tensile strength is deteriorated, and is unfavorable for the popularization of degradative plastics packaging bag and answers
With.
Therefore, to solve the above problems, providing a kind of new technical solution.
Summary of the invention
The present invention provides a kind of packaging bag with degradability.
The technical solution adopted by the present invention is that:
A kind of packaging bag with degradability, including polyvinyl alcohol, lubricant, filler, dicarboxylic acid ethyl ester, plasticizer and carbonic acid
Calcium.
Further, component is respectively as follows: by weight
45-55 parts of polyvinyl alcohol；
10-15 parts of lubricant；
1-3 parts of filler；
6-8 parts of dicarboxylic acid ethyl ester；
3-6 parts of antistatic agent；
1-3 parts of plasticizer；
10-15 parts of calcium carbonate.
Further, the filler is diatomite.
Further, the lubricant is graphite, nylon or boron nitride.
Further, the alcohol degree of degradation of the polyvinyl alcohol is 70-80%.
The beneficial effects of the present invention are: be embedded in after being combined as main component with other ingredients using polyvinyl alcohol rubbish or
When in soil, degradation effect clearly, is added to lubricant and Paris white, these adding ingredients can reinforced plastics strap
Tensile strength, reduce its breathable moisture permeability, so that plastic packaging bag is kept original characteristic, be conducive to degradative plastics packaging bag
It promotes and applies.
Specific embodiment
In order to deepen the understanding of the present invention, the present invention will be described in further detail with reference to the examples below, the embodiment
For explaining only the invention, it does not restrict the protection scope of the present invention.
Embodiment 1
A kind of packaging bag with degradability, including polyvinyl alcohol, graphite, diatomite, dicarboxylic acid ethyl ester, plasticizer and carbonic acid

The alcohol degree of degradation of polyvinyl alcohol is 70%
Embodiment 2
A kind of packaging bag with degradability, including polyvinyl alcohol, nylon, diatomite, dicarboxylic acid ethyl ester, plasticizer and carbonic acid
Calcium, component are respectively as follows: by weight
50 parts of polyvinyl alcohol；
13 parts of nylon；
2 parts of diatomite；
7 parts of dicarboxylic acid ethyl ester；
2 parts of plasticizer；
13 parts of calcium carbonate；
The alcohol degree of degradation of polyvinyl alcohol is 75%
Embodiment 3
A kind of packaging bag with degradability, including polyvinyl alcohol, boron nitride, diatomite, dicarboxylic acid ethyl ester, plasticizer and carbonic acid
Calcium, component are respectively as follows: by weight
55 parts of polyvinyl alcohol；
15 parts of boron nitride；
3 parts of diatomite；
8 parts of dicarboxylic acid ethyl ester；
3 parts of plasticizer；
15 parts of calcium carbonate；
The alcohol degree of degradation of polyvinyl alcohol is 80%
The beneficial effects of the present invention are: being embedded in rubbish or soil after combining as main component with other ingredients using polyvinyl alcohol
When middle, degradation effect clearly, is added to lubricant and Paris white, the drawing of these adding ingredients meeting reinforced plastics strap
It stretches intensity, reduce its breathable moisture permeability, so that plastic packaging bag is kept original characteristic, be conducive to the popularization of degradative plastics packaging bag
With application.
The above described is only a preferred embodiment of the present invention, being not the limit for making any other form to the present invention
System, and made any modification or equivalent variations according to the technical essence of the invention, still fall within present invention model claimed
It encloses.
