How to identify the quality of aluminum foil packaging bags?

Aluminum foil bag manufacturer Weihua Xiaobian today to talk about how to distinguish the quality of aluminum foil bags.

First, the material used in the aluminum foil bag: smell whether there is a special odor when you look at the sample purchase. If there is an odor, it does not meet health standards and may also affect the normal use of aluminum foil bags. If there is no special odor, you can check whether the clarity of the aluminum foil bag is uniform, whether there is a sense of impurities.

Second, look at the firmness of the aluminum foil bag: the firmness of the aluminum foil bag is mainly divided into two kinds, in line with the firmness and hot air firmness. Aluminum foil bags because of different materials, so the level of firmness is different. The main way to distinguish is to line up the edge of the bag and tear it by hand. The bag made of nylon and high pressure film is generally difficult to tear by hand, and can be used to install relatively heavy products such as semiconductor items, large particles, etc., while the bag made of OPP heat sealing film is very good to tear, and can only install some light products; After the bag is torn, it is necessary to look at the shape and structure of the section. If it is evenly torn from the middle of the hot sealing of the bag, it indicates that the hot sealing of the bag is poor and easy to break during the production process. If it is torn from the edge, it indicates that the hot sealing quality is good. Secondly, we also need to see the compound firmness of the packaging bag, the method is to see several layers of structure at the crack, and then see if you can separate it by hand, if it is not easy to separate, it shows that the compound firmness is good, if you gently pull it apart, it shows poor quality; Therefore, to check the firm level of the aluminum foil bag, it is also necessary to see whether the surface of the packaging bag has bubbles or wrinkles.

Third, look at the appearance of the aluminum foil bag uniformity: First observe the flatness of the aluminum foil bag. Generally, the higher the flatness, the better, but except for the different needs of materials, such as bags made of nylon and high-pressure film, the heat seal of the bag will be wavy; It is also necessary to observe whether the cutting edge of the bag is neat, the neater the better. Suzhou Haoxin Packaging not only produces aluminum foil bags, but also anti-static shielding bags and transparent vacuum bags.

Fourth, look at the printing quality of aluminum foil bag: look at the physical picture of the printing quality of aluminum foil bag, the higher the fidelity level, the better. Secondly, see if the bag has wire-drawing, fog plate, blocked plate, leakage and other phenomena, if this situation shows that the printing requirements are not standard. Now most aluminum foil bag manufacturers have cut corners.
