Analysis on the Causes of Wrinkling of Heat-sealed Aluminum Foil Packaging Bags Material

The edge sealing problem of heat-sealed aluminum foil packaging bags has always been a headache for many manufacturers. When sealing and heat sealing the edge of the aluminum foil packaging bag, if the temperature of the hot knife is high, the sealing edge will wrinkle, and if the temperature is low, it will not be able to seal. Various methods have been debugged, and the silicone pads and raw materials have also been changed, but it still cannot be solved. What can be done? As an experienced manufacturer and supplier of heat-sealing aluminum foil packaging bags, Haomei will introduce you to heat-sealing. Causes of wrinkling in aluminum foil packaging bags. We can consider it from two aspects, one is that the edge is wrinkled, and the other is that it cannot be sealed.

1. The phenomenon of hemming is usually due to:

1. The heat-sealing aluminum foil packaging bag material is not heat-resistant, and the high-temperature stamping material is wrinkled;

2. The glue and ink are not heat-resistant enough;

3. There are too many residual solvents in the glue and ink during the bleaching process, and the accumulation and volatilization during the bleaching process lead to the phenomenon of foam wrinkling;

4. The heat sealing knives of the bag making machine are parallel, the softness, hardness and flatness of the silicone do not meet the heat sealing requirements, and there are foreign objects on the heat sealing knives.

2. Regarding the problem that the heat-sealed aluminum foil packaging bag cannot be sealed, the reasons are usually:

1. The quality of the heat-sealing material is poor, the sealing temperature is too high or the heat-sealing performance is unstable;

2. The temperature of the heat sealing knife is too low.

Haomei suggests to check from several points, pay attention to the material source of the heat-sealed aluminum foil packaging bag, consult the supplier, and use the bag making machine. We recommend using a heavy duty bag maker, which can provide high heat sealing pressure and stable heat sealing temperature.
