Abstract

The present invention discloses a completely-bio-degradable plastic resin and production method of its film product. Its main raw material includes corn starch, cassawa starch, stearic acid, talcum powder, glycerine, sorbitol, ethylene-acrylic acid copolymer and full biological material. Its preparation method includes the following steps: mixing above-mentioned all the raw materials, using improved twin screw extruder to make extrusion and granulating.

Description

technical field [0001] The invention relates to packaging materials, in particular to a production method of a fully biodegradable plastic resin, and also relates to a production method of film products using the fully biodegradable plastic resin. Background technique [0002] As we all know, the increasing shortage of oil resources and rising oil prices have brought many adverse effects on people's daily life and work, seriously affecting the speed of social and economic development, and are also an unstable factor in the competition for resources between regions. For a long time, the plastic film products we use are all disposable film products made of petroleum synthetic resins, such as polyvinyl chloride, polyethylene and other materials, which are discarded as garbage after use. It takes about 200 years to be decomposed, so some are discarded everywhere, causing a very harmful "white pollution", and some are buried or burned, which greatly wastes the oil resources that ...
