Problems solved by technology

In the past, the plastic shopping bags attached to people's shopping are basically made of polymer materials such as polyethylene and polypropylene. They cannot be degraded, causing damage to the ecological environment and becoming "white pollution".
In order to reduce the formation of white pollution, the General Office of the State Council has restricted the use of plastic shopping bags in production and sales. For this reason, major supermarkets, shopping malls and other commodity retail places have implemented a system of paid use of plastic shopping bags; although paid use limits a certain number of shopping bags , but the symptoms are not a cure, and the pollution problem of the shopping bag itself has not been solved

Embodiment 1

[0012] Embodiment 1: raw material and consumption of preparing environmental protection shopping bag:

[0013] 15 kg of linear low-density polyethylene, 15 kg of ground calcium carbonate powder, 3 kg of ethylene-butylene copolymer, 18 kg of a blend of starch and polyvinyl alcohol, 15 kg of polyethylene, and 0.1 kg of toner.

[0014] The preparation method is as follows: add heavy calcium carbonate powder into a high-speed mixer, seal, heat and stir, the heating temperature is 70°C-80°C, and the stirring time is 3 minutes, open the sealing cover to disperse the mist, and then add polyethylene and linear low-density polyethylene , continue heating and stirring, the heating temperature is 70°C to 80°C, stir for 10 minutes, add ethylene butene copolymer and toner to obtain a mixed material; then the blend of starch and polyvinyl alcohol is extruded from the twin-screw extruder Add the fiber adding port, put the mixture obtained above into the twin-screw extruder, heat it to 190°C-...

Embodiment 2

[0015] Embodiment 2: prepare the raw material of environmental protection shopping bag and consumption:

[0016] 18 kg of linear low-density polyethylene, 25 kg of ground calcium carbonate powder, 2 kg of ethylene-butylene copolymer, 15 kg of a blend of starch and polyvinyl alcohol, 18 kg of polyethylene, and 1 kg of toner.

[0017] The preparation method is as follows: add heavy calcium carbonate powder into a high-speed mixer, seal, heat and stir, the heating temperature is 70°C-80°C, the stirring time is 5 minutes, open the sealing cover to disperse the mist, and then add polyethylene and linear low-density polyethylene , continue heating and stirring, the heating temperature is 70°C to 80°C, stir for 10 minutes, add ethylene butene copolymer and toner to obtain a mixed material; then the blend of starch and polyvinyl alcohol is extruded from the twin-screw extruder Add the fiber adding port, put the mixture obtained above into the twin-screw extruder, heat it to 190°C-210°...

Abstract

The invention discloses an environment-friendly shopping bag, and relates to the technical field of plastic products. The environment-friendly shopping bag is made of 15-18 parts of linear low-density polyethylene, 15-25 parts of heavy calcium carbonate powder, 2-3 parts of ethylene-butylene copolymer, 15-18 parts of starch and polyvinyl alcohol blending polymer, 15-18 parts of polyethylene and 0.1-1 part of toner. Compared with the prior art, the environment-friendly shopping bag has the advantages that the starch and polyvinyl alcohol blending polymer serves as a raw material, the environment-friendly shopping bag can be biologically degraded, the ethylene-butylene copolymer, starch and polyvinyl alcohol are added into the polyethylene, so that the polyethylene is modified, and the shopping bag has enough strength and stiffness.

Description

technical field [0001] The invention relates to the technical field of plastic products, in particular to an environment-friendly shopping bag. Background technique [0002] Compared with paper packaging bags, plastic flexible packaging has outstanding advantages such as moisture resistance and barrier properties, and is low in cost. In the past, the plastic shopping bags attached to people's shopping are basically made of polymer materials such as polyethylene and polypropylene. They cannot be degraded, causing damage to the ecological environment and becoming "white pollution". In order to reduce the formation of white pollution, the General Office of the State Council has restricted the use of plastic shopping bags for production and sales. For this reason, major supermarkets, shopping malls and other commodity retail places have implemented a system of paid use of plastic shopping bags; although paid use limits a certain number of shopping bags , but the symptoms are no...
