Case of PP plastic sheet in cooked food packaging tray

Why choose PP plastic sheet?

PP plastic sheet is widely used in the field of food packaging, especially thermoformed trays, due to its excellent properties such as heat resistance, chemical resistance, and food grade safety.

Heat resistance: PP material has a high melting point and can withstand a certain heating temperature, which is suitable for hot food packaging.

Chemical resistance: PP has good corrosion resistance to chemicals such as oils, acids, and alkalis, and can effectively protect food.

Food grade safety: PP material meets food grade standards, is non-toxic and odorless, and can directly contact food.

Cost-effectiveness: PP material is relatively economical and suitable for large-scale production.

Processability: PP material is easy to thermoform and can be made into trays of various shapes.

Advantages of thermoformed PP plastic trays in cooked food packaging

Protect food: PP trays can effectively isolate air, prevent food from oxidation and deterioration, and extend the shelf life.

Convenient transportation: The design of the tray can be easily stacked and save transportation space.

Enhance the appearance: The tray can be decorated by printing, embossing and other methods to enhance the product image.

Environmentally friendly and recyclable: PP materials are recyclable and meet environmental protection requirements.
