A1: Pulp coated products are one of the pulp molded products. Pulp film-coated products refer to the process of combining the composite film and the molded product through a composite process on the molded product with or without any additives.
Q2: What are the characteristics of the composite film of the pulp coated product?
A2: The composite film has a strong tensile force, and the composite product can be better insulated and reduce the heat dissipation through the pores of the molded product. At the same time, it can reduce the stickiness of rice, dumplings and other foods, and to a large extent can reduce the use of water-repellent and oil-repellent agents.
Q3: What are the composite films of pulp coated products?
A3: The composite film of pulp-laminated products is generally divided into PP, PE, PET, CPET, PBAT, PLA, etc. Currently, the commonly used composite membranes are mainly PLA and PBAT.
Q4: What is PLA?
A4: PLA is a new type of biodegradable material, which is made from the starch raw materials proposed by renewable plant resources (such as corn) and is a fully degradable film. Therefore, for technical reasons, it is currently not possible to produce in China. It mainly relies on imports from the United States, Japan, Germany and Taiwan, which are expensive and limited in quantity.
Q5: What is PBAT?
A5: PBAT is a copolymer of butylene adipate and butylene terephthalate, which has the characteristics of both PBA and PBT. PBAT not only has better ductility and elongation at break, but also better heat resistance and impact properties. In addition, PBAT also has excellent biodegradability. It is very active in the research of biodegradable plastics and one of the best degradable materials in the market. Its price is much lower than PLA and can be produced in China. Therefore, PBAT is currently a molded product. The most widely used and most used composite material in China.
