As a kind of packaging product, foil aluminum bags packaging is undoubtedly one of the basic functions that aluminum foil bags should have. Strict attention should be paid to the production quality to avoid quality problems in the produced aluminum foil bags and appear in the market. Correspondingly, the production quality inspection of foil aluminum bags is also very important.

Production quality inspection of foil aluminum bags:

First, when inspecting the produced foil aluminum bags, we can intuitively feel the printing quality problems of the aluminum foil bags, such as whether there is wire drawing, fogging, blocking, missing printing, etc., and the two colors printed on the surface of the aluminum foil bags are spliced. whether there is a third color;

Secondly, after observing the printing quality of the aluminum foil bag, it is necessary to check the material quality of the aluminum foil bag. A quality aluminum foil bag should be odorless and tasteless in terms of materials, and for an aluminum foil bag without peculiar smell, it is also necessary to check whether the transparency and clarity of the packaging bag are uniform and free of impurities.

Furthermore, the function of the foil aluminum bags in protecting the goods is the firmness and heat sealing strength of the aluminum foil bag. We can directly tear it at the edge of the foil aluminum bags to test it. The aluminum foil bag made of nylon and high-pressure film is generally It is difficult to tear by hand and can be used to hold heavier products, while aluminum foil bags made of OPP heat-sealing film are easy to tear and can only hold some lighter products.

At the same time, after the foil aluminum bags is torn, it depends on the shape and structure of the section of the aluminum foil bag. If it is torn evenly from the middle of the heat seal of the aluminum foil bag, it means that the heat sealing performance of the aluminum foil bag is poor; if it is torn from the sealing edge , indicating that the heat sealing quality is good.
