Degradable bag containing aluminum foil and preparation method thereof

Abstract

The invention discloses a degradable bag containing aluminum foil. The degradable bag containing aluminum foil is prepared from the following raw materials by weight: 10-20 parts of wheat straw pulp fiber, 30-50 parts of purple sweet potato powder, 80-100 parts of tapioca flour, 90-120 parts of shell powder, 100-130 parts of corn flour, 70-100 parts of pumpkin peel powder and 70-100 parts of coconut shell powder. A main body of the degradable bag containing aluminum foil is mainly composed of a first layer of base material, a second layer of base material and a third layer of base material from outside to inside, the first layer of base material is kraft paper or PLA, and the second layer of base material is PLA aluminum plated foil; and the third layer of base material is PLA. The preparation method of the degradable bag containing aluminum foil comprises the following steps of: bag lamination: coating the surface of kraft paper with an environment-friendly glue, carrying out extrusion compounding on the kraft paper in a wet state and the first layer of PLA base material through a compounding device, and then carrying out extrusion compounding with the second layer of PLA base material through a compounding device to prepare a compound semi-finished product; and drying and forming: removing the solvent by drying in a curing chamber, and compounding the three layers of base materials together. The degradable bag containing aluminum foil provided by the invention is environmentally friendly and beneficial to land planting.

Description

technical field [0001] The invention relates to the technical field of packaging paper, in particular to a degradable bag containing aluminum foil, in particular to a degradable bag containing aluminum foil and a preparation method thereof. Background technique [0002] Plastic bags are bags made of plastic (commonly used plastics include polyethylene, polypropylene, polyester, nylon, etc.) as the main raw material. They are indispensable items in people's daily life and are often used to hold other items. thing. It is widely used because of its advantages of cheapness, light weight, large capacity and easy storage, but its production and use are banned by some countries due to the disadvantages of extremely long degradation cycle and difficult disposal of plastic bags. According to relevant national laws and regulations, supermarkets restrict the use of plastic bags, and foreign countries, Europe and the United States and other countries advocate the trend of using environ...

[0003] But, in the prior art, because no matter plastic bag is difficult to decompose, or recyclable paper bag, all causes certain pressure to land environment, when discarding in land, both all can pollute land, although paper bag is harmful to land environment. The degree of pollution is lower than that of plastic bags, but when people gradually replace plastic bags with paper bags, the number of paper bags will increase. In the absence of an effective recycling mechanism, a considerable number of paper bags will be discarded and buried in the ground, causing land pollution. Pollution

Burning paper bags will cause environmental pollution
