　　First, observe the tightness of the seal. If there is a small joint in the seal, the product is considered unqualified.

　　Secondly, visually inspect the surface of the vacuum packaging bag for composite food for scratches and pinholes. Focus on checking whether the seals are contaminated. It cannot be determined immediately by visual inspection, and slight negligence is the cause of erosion in the future. Check the seal, spray the surface active agent with dye on the seal, see if it passes, and determine the adhesion of the seal.

　　Then comes the seal strength test. Check the sealing of the composite vacuum packaging bag and cut it into 15mm wide strips. Use a material tester to measure the strength of the seal at a rate of 300 ± 20mm/min. Generally, the sealing strength of the composite bag shall reach 2334N./15mm.
