Pulp food packing box is a kind of biodegradable lunch box made by using plant fiber, which is usually made of wheat straw, bagasse and other plant fibers as raw materials, and molded by pulp molding wet pressing process. Food-grade additives such as water and oil repellents are added to the pulp to meet food contact requirements. These boxes are environmentally friendly and can be naturally decomposed after use, reducing their impact on the environment.

Disposable packing boxes are boxes used for disposable packing, usually for takeaways, home meals or food storage. They can be made from a variety of materials, such as food-grade polypropylene (PP) plastic pellets. Disposable packing boxes come in a variety of styles, including square, round, shaped, American, Japanese, etc. and are lightweight, flexible, and heat resistant.

ps raw material, chemical name: polystyrene (Polystyrene, abbreviation PS), is a polymer synthesized from styrene monomer by free radical polymerization reaction. It is a colorless and transparent thermoplastic with a glass transition temperature higher than 100°C. Therefore, it is often used to make a variety of disposable containers that need to withstand the temperature of boiling water, disposable tableware, etc., avoiding the cross-contamination that occurs with repeated use.

Polypropylene (PP) is a thermoplastic addition polymer made from a combination of propylene monomers. It is white, semi-transparent and waxy when uncolored; it is lighter and has better transparency and rigidity than polyethylene (PE). Polypropylene (PP), a highly recyclable plastic, has excellent properties that are best demonstrated in the field of tableware manufacturing. Not only is it known for its safety and non-toxicity, which ensures health when coming into direct contact with food, but it also provides tableware with a strong and durable character thanks to its excellent rigidity.
