Is the Aluminum Foil Bag Puncture Resistant?

How to improve the easy puncture problem of aluminum foil bags? It is mainly used in aluminum foil packaging bags for industrial electronic products. Its piercing resistance is not good. The product is in contact with the air or is easily damp, which affects the performance of the product. We look at it from the following points.

1. In the process of product transportation, storage, and sales, it will inevitably be affected by external forces. Inertial pinholes will be formed during the process of rubbing, resulting in puncture of the packaging bag and destroying the vacuum packaging. We can determine the stress condition and avoid it through the rubbing resistance test and the puncture resistance test, and the experimental value comparison.

2. There is a puncture of sharp objects on the product in the package. For example, the corners of aluminum foil bags will scratch the body of other packaging bags and puncture the electronic components on the PCBA. We can do the corresponding vacuum test to test the larger force of the bag.

3. The thickness of the aluminum foil bag and the material and thickness of the composite film can be adjusted reasonably according to the characteristics and specifications of the inner product itself, and the flexibility of the aluminum foil bag can be increased to prevent the inner product and the outside from scratching or puncturing the bag.

Aluminum foil bag manufacturers will customize corresponding aluminum foil bags, or shielding bags and other products such as vacuum packaging bags according to the inner products.

The oxidation of aluminum foil bags will not only reduce their quality, but some will also generate heat during the oxidation process, but spontaneous combustion also occurs, and some accidents will occur.

The chemical oxidation of the aluminum foil bag means that the aluminum foil bag contacts the oxygen in the air or the oxygen released by other substances, and the chemical change that combines with the oxygen occurs. These products will discolor or harden when exposed to sunlight for a long time, which is the result of oxidation of the aluminum foil bag. There are many products that are prone to oxidation, such as some chemical raw materials, fiber products, rubber products, oil products, and fiber fabrics such as cotton, linen, and silk.

In general, grease aluminum foil bags will spontaneously oxidize when exposed to air, changing their properties and smell. This oxidation is generally carried out in the manner of auto-oxidation, that is, in a three-stage chain reaction of initiation, propagation, and termination. Even adding antioxidants cannot prevent oxidation, but can only delay the induction period of the reaction and reduce the reaction speed.
