Elastic starch based environmental foam products

With the development of our country's economy, the consumption of packaging materials is increasing. At present, the raw materials of polystyrene, PVC, polyurethane and other foamed products used in packaging materials are mostly made from petroleum as raw materials, and are not degradable and have great environmental hazards. Starch-based foamed articles have biodegradable biological properties and are particularly suitable environmentally friendly packaging materials.

Starch-based environmentally friendly foaming products use starch and other natural substances as raw materials, and adopts modern foaming processing technologies such as reactive extrusion to prepare biodegradable and environmentally-friendly foaming materials, which can replace non-environmentally friendly polyolefin foams and pass starches. Improve and plasticize. In the foaming process, the natural elastic polymer crosslinks to form a three-dimensional network, so that the foam material has high elasticity and strength, and is used for cushioning and shock absorption of packaging products.

The technical content of the elastic starch-based environmental protection foam products includes reaction cross-linking, extrusion, and foaming of the starch and the elastic polymer. With starch and other natural polymers as raw materials, all foamed products can be degraded by the environment without environmental pollution; raw materials have a wide range of sources, prices are low, and raw material costs are not affected by the price of oil.
