How to test the aluminum foil bags production quality?

In daily life, aluminum foil bag because of its superior performance and eye-catching appearance, the packing of the products are widely used in all walks of life favored by the market. As with regular packing, to make the aluminum foil bag to protect the goods, in terms of quality must be pass, so, we should how to test the quality of the produced aluminum foil bags? Today, small make up teach you how to distinguish the quality of the aluminum foil bags. 1, aluminum foil bag printing quality: see the joining together of two colors whether have obvious of the third color, physical figure of realistic level, the higher the better, see if there is a wire drawing, fog version, edition, printing and other phenomena. 2, aluminum foil packaging materials: packing bags need no peculiar smell. Smell the packing bag of let a person feel generally do not conform to the hygiene standards, may also affect the normal use of the packaging bags. Without peculiar smell, need to check bags transparency, clarity is even, no impurity and so on. 3, aluminum foil bags and firm level: packaging fastness mainly divided into two kinds, in line with the strong and hot air solid degrees. Aluminum foil bags for different based on different levels so strong. Main distinction method is on the bag sealing side by hand. Tear the bag, to look at the shape of cross section and structure, if from evenly split between heat sealing bag, bag heat sealing is very poor, the packages to work open during the production process. Also look at the bag of composite reinforcement, the method is to first look at the gap in several layers of structure, reoccupy hand look at can you separate it, if it is not easy to separate, then composite fastness is good, the opposite is poor; In addition, the test bag firm level and at the same time it remains to be seen whether the bag surface bubbles or buckling, etc. 4, the uniformity of appearance: to observe stiffness of the packaging bags. General flatness is higher, the better, but due to the difference of materials needed. Such as made of nylon and high-pressure composite membrane bags, aluminum foil bag heat sealing have wavy; Remained to be seen whether the aluminum bag trimming and tidy, as tidy as possible.
