Organ-shaped degradable bag and preparation method thereof

Abstract

The invention discloses an organ-shaped degradable bag. The organ-shaped degradable bag is characterized by being prepared from the following raw materials by weight: 10-20 parts of wheat straw paperpulp fiber, 10-50 parts of sweet potato powder, 10-20 parts of tapioca flour, 30-50 parts of barley husk powder, and 70-150 parts of Melaleuca leucadendron bark fiber; wherein the organ-shaped degradable bag comprises eight edges; a main body of the organ-shaped degradable bag can be synthesized by a first base material, a second base material and a third base material from outside to inside, thefirst base material is multilayer kraft paper, and the second base material and the third base material are both PLA; the main body of the organ-shaped degradable bag can also be composed of two layers of kraft paper and PLA or composed of PLA-PLA from outside to inside. The invention further provides a preparation method of the organ-shaped degradable bag. The preparation method comprises the steps of base material forming, gelatinized liquid material polycondensation and drying treatment. The raw materials adopted by the invention can be digested by microorganisms, damage to the environmentis reduced, and the animal and plant powder can serve as fertilizer after being degraded and is beneficial to land.

Description

technical field [0001] The invention relates to the technical field of packaging, in particular to a degradable bag, especially an organ-shaped degradable bag 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 cheap, extremely light weight, large capacity, and easy storage. While plastic brings convenience to people's life, it also brings troubles to the environment that are difficult to deal with. People call the disaster brought by plastic to the environment "white pollution". Plastics are chemical petroleum products derived from petroleum or coal, and once produced are difficult to degrade naturally. China's annual output of plastics is 30 million tons, and its consumption is more...

Problems solved by technology

However, in the prior art, since waste plastics will produce harmful gases to the human body during incineration or reprocessing and pollute the environment, it can be said that the disposal of waste plastics is still a major problem in environmental protection work.
