1. Non-proof pulp molded products
Refers to non-waterproof and non-oil-proof formed products. These products are mostly used in electronic lining products, and there is no requirement for waterproof and oil-proof characteristics for this type of packaging.
2. Single-proof pulp molded products
Usually refers to waterproof products. Adding a certain proportion of waterproofing agent (divided into food grade and industrial grade) to the slurry can play a waterproof role. The waterproof temperature ranges from minus 18 degrees to 100 degrees.
Single-prevention products are mostly used in agricultural disposable nursery cups, as well as some fruit pulp trays, meat pulp trays, etc.
3. Double-proof pulp molded products
It means that a certain proportion of water and oil repellent is added to the slurry to play the role of water and oil repellency of the product. The waterproof effect generally ranges from minus 18 degrees to 100 degrees; the oil resistance effect ranges from a few degrees to 220 degrees. The dual-proof products can be used in the microwave heating and oven baking process. Double-proof products are mostly suitable for food packaging tableware.
4. Laminated products
It refers to the process of combining the composite film and the molded product through the composite process on the molded product with or without any additives. The composite film has a strong tensile force, and the composite product can be better Insulation can reduce the heat dissipation through the pores of the molded product. At the same time, it can reduce the stickiness of food such as rice and dumplings, which can greatly reduce the use of water-repellent and oil-repellent agents.

Composite membranes are generally divided into PP, PE, PET, CPET, PBAT, PLA, etc. The currently commonly used composite membranes are mainly PLA and PBAT. PLA is a new type of biodegradable material that uses renewable plant resources (such as corn). The proposed starch raw material is made of all degradable films.
PBAT is a copolymer of butylene adipate and butylene terephthalate. It has both the characteristics of PBA and PBT. It has good ductility and elongation at break, as well as good heat resistance. And impact performance;
In addition, it 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 it can be produced in China. Therefore, PBAT is currently among the molded products. The most widely used and most used composite material.
