Aluminum foil bags fastness check method, really used for?

When we looked at the aluminum foil bag, usually check it fast unstable, actually check is right, only the strong aluminum bag can be used by people, but you really review the use of?

Aluminum foil bags for different based on different levels so strong. Main method is to aim at the distinction between bags sealing side by hand. Made of nylon and high voltage composite membrane bag generally it is hard to tear by hand, can be used to compare a heavy products such as semiconductor items, such as large particles, and hot sealing membrane made of OPP bag tear is good, can only put some light products. Tear aluminum foil bags, to look at the shape of cross section and structure, if from evenly split between heat sealing bag, bag heat sealing is very poor, easy to broken during production, if the tear from sealing side, heat sealing quality is better. Secondly the compound fastness to also look at the aluminum foil bags, method is to first take a look at several segments layer structure, reoccupy hand look at can you separate it, if it is not easy to separate, then composite fastness is good, if a gently pull it apart, explain quality is poor.
