PP sheet case: Thermoformed packaging tray for seafood products

The main challenges faced in the project include:

Low temperature resistance requirements: Seafood products are usually stored in low temperature environments, so the pallet material must have excellent low temperature resistance to avoid brittle cracking during freezing.

Food grade safety standards: Pallet materials must meet strict food grade safety standards to ensure that no harmful substances are precipitated when they are in direct contact with food.

Moisture and seepage prevention: Pallets need to have good moisture resistance to prevent moisture penetration from affecting the freshness of seafood products.

Environmental protection requirements: With increasingly stringent environmental regulations, customers require pallet materials to not only have superior performance, but also be recyclable and have low environmental impact.

PP (polypropylene) sheet is a widely used thermoplastic material with excellent mechanical properties and chemical stability. Its low temperature tolerance and good processing performance make it an ideal choice for the food packaging field.

PP sheet not only meets food grade safety standards, but also has good impact resistance and moisture resistance, which is very suitable for food packaging scenarios such as refrigeration and freezing.

In addition, PP materials can be recycled and reused, which is in line with the current trend of environmental protection and sustainable development.
