How to identify whether the packaging of the vacuum bag meets the standard?
Regarding whether the packaging of the vacuum bag is in compliance with the standard, Jiuzhi Plastics Network believes that there are mainly the following factors:
First of all, from the sealing adhesion, if there are some small slits in the seal, this is judged as a substandard product.
Secondly, from the visual appearance, visually check the surface of the composite vacuum bag for significant scratches and pinholes. Check the seal for contamination.

View this seal ç‘•ç–µ can be sprayed in the seal with a dye-coated surfactant to see if it passes or not to distinguish the seal.
Finally, the sealing strength test observation, the seal of the composite vacuum packaging bag to be inspected, cut a strip of 15 mm wide, and measure the sealing strength with a versatile material measuring instrument at a speed of 300±20 mm/min. Generally, the sealing strength of the composite bag should reach 2334N. /15mm.
