Problems solved by technology

[0003] Plastic bags are common daily necessities for people nowadays. Plastic bags are widely used in large and small supermarkets and all walks of life due to the advantages of bright colors, novel patterns, convenient use, and low price. However, the plastic bags currently on the market are mainly polyethylene plastic bags. Mainly, it brings serious pollution to the environment, and it is also called "white pollution" because of its refractory property, and it will release harmful gas itself, which poses a threat to people's health. The application number is CN00110323.7, which discloses a plastic The product

Example Embodiment

[0019] Example 1:

[0020] A kind of plastic bag production process of the present embodiment is characterized in that, its process steps are as follows:

[0021] (1) Screening of raw materials: the plastic particles are screened by an 80-mesh sieve, and the plastic particles are polylactic acid particles;

[0022] (2) Melting: Add the target particles screened in step (1) into the reactor, control the temperature at 175°C, and melt the target particles into a molten state under stirring conditions;

[0023] (3) Modification: add the modified material into the molten liquid in step (2), and mix evenly, the modified material is a mixture of magnesium-aluminum hydrotalcite, ammonium polyphosphate, and cobalt powder, and the mixing ratio is 2 :1:1, the content of the mixture is 2% of the melt;

[0024] (4) Film blowing: the mixed melt in step (3) is formed into a plastic film by a film blowing machine;

[0025] (5) Color printing: The pattern set according to the requirements...

Example Embodiment

[0028] Example 2 : the rest are the same as described in Example 1, except that step (1) is changed to a 150-mesh sieve, the content of the mixture in step (3) is 3% of the melt, and in step (1), the The plastic particles are polylactic acid particles.

Example Embodiment

[0029] Example 3: The rest are the same as described in Example 1, except that, in step (3), the content of the mixture is 5% of the melt, and in step (3), the modification condition is vacuum stirring.

[0030] Example 1 Example 2 Example 3 Complete melting time of plastic pellets 50min 35min 55min Complete degradation time of plastic bags 35d 28d 20d

[0031] Through the above three examples, there are three sets of data in the above table, it can be known that when the plastic particles are controlled at 120 mesh, the particle melting speed is the fastest, and when the modified material content is 5%, the complete degradation time of the plastic bag is the shortest.

[0032] The present invention completes the production process of the plastic bag through seven steps of screening, melting, modification, film blowing, color printing, slitting and bag making of the raw materials of the polylactic acid plastic particles, so that the pro...

Abstract

The invention discloses a plastic bag production technology. The technology comprises the steps of screening raw materials, melting, modifying, film blowing, color printing, parting off, and bag making. The plastic bag production technology is reasonable, concise, reasonable in material selection, low in cost, and capable of degrading quickly, greatly shortens technology processes, and reduces environment pollution. Most importantly, the heat resistance, the abrasion resistance and tenacity of a plastic bag are improved on the basis of the original performance of a plastic bag. The plastic bag production technology is safe, convenient, reliable, and has wide market prospects.

Description

[0001] technical field [0002] The production process of plastic rubber that the present invention relates to, particularly relates to a kind of plastic bag production process. Background technique [0003] Plastic bags are a common daily necessities for people nowadays. Plastic bags are widely used in large and small supermarkets and all walks of life due to their bright colors, novel patterns, convenient use, and low price. However, the plastic bags currently on the market are mainly polyethylene plastic bags. Mainly, it brings serious pollution to the environment, and is also called "white pollution" because of its refractory property, and it will release harmful gas itself, which poses a threat to people's health. The application number is CN00110323.7, which discloses a plastic The production process of the bag, which uses high-density polyethylene as the main raw material, mixes processing aids, biodegradation aids, dispersion aids, and photosensitizers in a certain p...
