Aluminum foil bag is a packaging product that combines various packaging lengths, with low cost and exquisite printing; The product has an opaque appearance, a silver white color, with a reflective luster, good barrier and heat sealing properties, as well as light blocking, high temperature resistance, low temperature resistance, oil resistance, and fragrance retention; Non toxic and odorless; Features such as softness. Joint planning, new printing process, can plan special trademarks or pictures, play a good anti-counterfeiting role, and can increase product grade, becoming a good choice for packaging bags now.

As a type of packaging product, aluminum foil bag packaging undoubtedly has one of the basic functions that aluminum foil bags should have. Strict attention should be paid to production quality to avoid various quality problems in the produced aluminum foil bags and their appearance in the market. Correspondingly, the production quality inspection of aluminum foil bags is also extremely important. Here are some common tips to share:

Firstly, when inspecting the produced aluminum foil bags, we can visually see the printing quality issues of the aluminum foil bags, such as whether there are any wire drawing, misting, blocking, or missing printing, and whether there is a noticeable third color at the junction of the two colors printed on the surface of the aluminum foil bag;

Secondly, after observing the printing quality of the aluminum foil bag, it is necessary to carefully inspect the material quality of the aluminum foil bag. A high-quality aluminum foil bag should be odorless and odorless in terms of materials used, while for aluminum foil bags with no odor, it is also necessary to check whether the transparency and clarity of the packaging bag are uniform and free of impurities.

Furthermore, the intuitive performance of aluminum foil bags in protecting goods is their firmness and heat sealing strength. We can directly aim at the edge of the aluminum foil bag and tear it by hand to inspect. Aluminum foil bags made of nylon and high-pressure film composite are generally difficult to tear open 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 lighter products.

At the same time, after tearing the aluminum foil bag, it is necessary to observe the shape and structure of the cross-section of the aluminum foil bag. If it is evenly torn from the middle of the heat sealing area of the aluminum foil bag, it indicates that the heat sealing performance of the aluminum foil bag is poor; If it is torn from the edge, it indicates that the heat sealing quality is good.
