Therefore, in order to ensure food safety, strict inspection is required.

★ Composite film food plastic packaging bags should arrive during the inspection process: the appearance should be flat, without scratches, burns, bubbles, broken oil, or wrinkles, and the heat seal should be flat without false seals. The film should not separate cracks, pores and composite layers. Free of impurities, foreign matter and oil stains. Additionally, bagged soaking solutions should be free of odor, odor, turbidity, and discoloration.
★ During the inspection process, single-film food packaging bags should meet the following requirements: the appearance must not have defects such as bubbles, perforations, water lines, exposed ribs, poor plasticization, fish-eye stiffness, etc. Specifications, width, length and thickness deviations should be within the specified range. Physical and mechanical properties include tensile strength and elongation at break, which reflect the tensile ability of the product during use. If this item is not up to standard, food packaging bags can easily break and be damaged during use.
★ Plastic packaging bags have very strict requirements for packaging food. They must be non-toxic and harmless, comply with national laws and regulations, and comply with corresponding mandatory standards.
