Is there a national standard for vacuum packaging bags? What are the requirements?

The national standard for vacuum packaging bags is mainly the "GB/T 19741-2005 Food Plastic Composite Film and Bags" issued by the National Standardization Administration of China. This standard specifies the requirements for materials, structure, performance, inspection methods, labeling, packaging, storage, and other aspects of vacuum packaging bags.
Different standards have the following specific requirements and characteristics for vacuum packaging bags:
1. Material: Vacuum packaging bags should be made of plastic composite film materials that meet food standards. Different standards may have different requirements for the types and usage of materials.
2. Structure: The structure of vacuum packaging bags should comply with relevant national hygiene standards and environmental requirements. For example, it is required that the inner layer can bond well with the packaged food to prevent secondary contamination.
3. Performance: Vacuum packaging bags should have strong pressure resistance and be not easily broken or leaked under vacuum conditions. Different standards have different regulations on the pressure resistance, heat resistance, frost resistance, oxygen permeability and other indicators of products.
4. Testing methods: Corresponding testing methods will be designed for different requirements according to different standards to ensure that the quality of the product meets the standards.
Overall, the requirements of national standards for vacuum packaging bags are to ensure their quality, safety, applicability, and environmental friendliness, allowing consumers to purchase safe and hygienic products.
