Production method of foamed incasement

Abstract

The invention relates to a production method of a foam wrappage. One or a plurality of biomass material is chosen to be crushed and blended with powder containing starch, a proper amount of filler and additive and certain amount of water are added, and then all the material are blended to become mixed raw material which then is put into a mould with a certain degree of sealing in a certain temperature. The mould is sent into a microwave equipment or the other baking equipment, or the microwave and other baking equipment which are used together to be baked, so that the mixed raw material produces steam pressing expansion and is foamed and cured in mold and then is output, the mold is opened, the foam wrappage with high foam rate is produced.

Description

technical field [0001] The invention relates to a production method of a biomass foam package. Background technique [0002] For a long time, due to the advantages of low price, high foaming rate and good performance, petroleum-based plastic foams have made other materials unable to compete. With the improvement of people's environmental protection requirements, petroleum-based plastic foams cannot be naturally degraded. It has become increasingly prominent. For this reason, packaging materials produced with biomass as raw materials have begun to appear, but most of them are hard products with strong pressure. During the production process, a press is generally used to fix the mold, and the mold is directly heated by electricity or steam. Compression molding, the main purpose of heating is to dry and solidify the packaging, therefore, the foaming rate of the product is extremely low, the amount of material used is large, and the weight is heavy, and it needs to be carried ou...

[0002] For a long time, due to the advantages of low price, high foaming rate, and good performance, petroleum-based plastic foams have made other materials unable to compete. With the improvement of people's environmental protection requirements, petroleum-based plastic foams cannot be naturally degraded. For this reason, packaging materials produced with biomass as raw materials began to appear, but most of them are hard products with strong pressure. During the production process, a press is generally used to fix the mold, and the mold is directly heated by electricity or steam. Compression molding, the purpose of heating is mainly to dry and solidify the package, therefore, the foaming rate of the product is extremely low, the amount of material used is large, and the weight is heavy, and it needs to be carried out without cutting off the power supply or steam during the production process. Mold opening or feeding, resulting in easy heat dissipation and high energy consumption
