Folha de plástico PP 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.
Resistência química: 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.
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.
Deli food refrigerators:
Fast food industry:
Supermarkets and convenience stores:
Sheet preparation: Cut the PP plastic sheet into the required size.
Heating and softening: Heat the sheet to a softened state.
Vacuum forming: Put the softened sheet into the mold and use vacuum suction to adsorb the sheet on the mold to form the required shape.
Cooling and shaping: After cooling, the sheet solidifies and forms.
Trimming: Trim excess scraps.
Packaging: Package the formed pallet.
With the continuous improvement of people’s awareness of food safety and environmental protection, the requirements for food packaging materials are also getting higher and higher. In the future, the development trend of thermoformed PP plastic pallets is as follows:
Functionalization: Develop PP materials with antibacterial, anti-fog, oxygen barrier and other functions to meet the packaging needs of different foods.
Degradability: Develop degradable PP materials to reduce environmental pollution.
Intelligence: Combined with sensors and other technologies, it can realize real-time monitoring of food.
Thermoformed PP plastic sheets have broad application prospects in the field of cooked food packaging. Its excellent performance, good processability and environmental protection make it one of the preferred materials for food packaging. With the continuous development of technology, PP plastic sheets will play a greater role in the field of food packaging.
