Aluminum foil bags are one of the most widely used types of packaging bags in our daily lives, and we may encounter some problems during use. For example, some merchants have beautiful printing and bag shapes for aluminum foil bags, but the corners are tilted outward, which seriously affects the aesthetics of the product. At the same time, it will greatly reduce the moisture-proof effect of aluminum foil bags. This is the layering of aluminum foil bags. What is the reason for the layering of aluminum foil bags? Below, we will provide a detailed breakdown of this issue to help everyone understand and prevent such incidents from happening in advance.

Generally, we attribute the problem of aluminum foil bag delamination in production to the lack of firm composite, which can be caused by many reasons: 1. poor melt elasticity and low melt index; 2. The extrusion temperature is low; 3. Insufficient corona treatment of the substrate, moisture or dirt can cause serious delamination of the aluminum foil bag; 4. The pressure of the pressure roller is low; 5. Insufficient thermal oxidation of the melt, low polarity, and poor adhesion; 6. Poor printability of ink; 7. Poor moisture resistance of AC or improper selection of substrate; 8. Insufficient AC coating or expired service life; 9. Insufficient AC drying.

The solution for aluminum foil bag delamination: 1. Use resin with appropriate melt density and melt index; 2. Increase the extrusion temperature or preheat the substrate; 3. Re corona treatment, cleaning and preheating of corona substrate; 4. Increase the pressure of the pressure roller; 5. Increase the air gap and reduce the recombination speed; 6. Replace with appropriate ink; 7. Replace the AC system; 8. Increase the amount of glue applied or use a new AC machine; 9. Increase the drying temperature and reduce the winding speed.

These are some theoretical issues discussed from the perspective of production, but in reality, the actual problems are also very simple. We can report the goods in advance appropriately, provide sufficient production time, and do not add any extra rush to activate. Generally, the above problems will not occur. In theory, there are many problems that can cause delamination, but in actual aluminum foil bag production, many problems will not occur, The general reason for the delamination of aluminum foil bags is that the curing time of aluminum foil bags is not enough, and the short curing time is the main reason for the delamination of aluminum foil bags
