Problems solved by technology

However, in the prior art, since plastics are chemical petroleum products extracted from petroleum or coal, and petroleum is a non-renewable resource, the production of plastic bags will inevitably consume petroleum resources and cause waste of resources
In addition, burning garbage will also emit carcinogenic gases, which will pollute the atmosphere
Advanced plastic bag incinerators need to invest a lot of money, which increases the cost of plastic bag recycling

Abstract

The invention discloses a degradable transparent bag which is prepared from the following raw materials in parts by weight: 30-50 parts of oyster shell powder, 60-80 parts of algae powder, 80-120 parts of tapioca flour, 80-120 parts of straw powder and 60-80 parts of nanocellulose. The main body of the degradable transparent bag is mainly synthesized by a first base material and a second base material from outside to inside, and the first base material and the second base material are PLA. The nanocellulose is extracted from coconut trees or mango trees. The preparation method comprises the steps of raw material weighing, first mixture preparation, second mixture preparation, third mixture preparation, base material forming, bag pressing and drying forming, wherein a composite semi-finished product is sent to a curing chamber to be dried to remove a solvent, and the two layers of base materials are compounded together. The strength of the transparent bag can be enhanced by using the bamboo leaf fiber powder and the nano cellulose, so that the strength of the transparent bag is improved. The bamboo leaf fiber can also be used as fertilizer, and the PLA can be biologically degraded and has a promoting effect on environmental protection and the soil fertility degree.

Description

technical field [0001] The invention relates to the technical field of packaging, in particular to a transparent bag, especially a degradable transparent bag and a preparation method thereof. Background technique [0002] The transparent bag or transparent woven bag is made of brand new material polypropylene through wire drawing. Its characteristic is that the woven cloth is transparent, and the products in the bag can be seen through the woven bag. It is generally used for the packaging of agricultural products such as vegetables and melon seeds. Transparent bags are generally prepared from plastic. Plastic is a very light substance, which can be softened by heating at a very low temperature, and can be made into various shapes as one likes. Plastic products are bright in color, light in weight, not afraid of falling, economical and durable. Its appearance not only brings a lot of convenience to people's life, but also greatly promotes the development of industry. Plastic...
