What are the hygiene requirements for food-grade TPU films?

Food-grade TPU film, also known as thermoplastic polyurethane film, is widely used in the field of food packaging due to its excellent physical properties and chemical stability. For such materials that come into direct contact with food, the hygiene requirements are very strict, mainly including the following aspects:

1. Material safety: Food-grade TPU film must be produced using raw materials that meet food safety standards to ensure that it does not contain harmful substances, such as heavy metals, migration of harmful substances, etc.

2. Production process control: During the production process, the production environment should be strictly controlled to avoid pollution, ensure the cleanliness of the production workshop, and regular cleaning and disinfection of production equipment and tools.

3. Quality testing: Products need to undergo strict quality testing before leaving the factory, including microbial testing, chemical composition analysis, etc., to ensure that the products meet food safety standards.

4. Packaging and storage: Food-grade TPU film should also avoid contamination during the packaging and storage process, use clean, non-toxic packaging materials, and store it in a dry and well-ventilated environment.

5. Regulatory compliance: Companies that produce and sell food-grade TPU films must comply with relevant national and international food safety regulations and standards, such as FDA, EU food contact materials regulations, etc.

6. Traceability: In order to ensure product safety, the production and supply chain of food-grade TPU films should be traceable so that when problems occur, they can be quickly located and solved.

In summary, the hygienic requirements for food-grade TPU films cover the entire production and supply chain process from raw material selection to final products, ensuring their safety and hygiene to protect consumer health.
