How to Seal the Plastic Packaging Bag?

 Sealing machine can be used for sealing. Follow the machine instructions.

Ordinary single-layer plastic packaging bags can be sealed with a foot sealer. For multi-layer composite plastic packaging bags, such as PET plastic packaging bags, a high temperature of 200 degrees is usually required to seal the bag.

Ordinary plastic packaging bags are single-layered. Such a bag is thin and can be sealed at low temperature. When the temperature is high, the bag will be burned. Therefore, the temperature must be tested repeatedly when sealing. If the bag is broken and the surface is flat, this temperature is the right temperature. Usually this kind of bag uses a foot-operated sealing machine.

The multi-layer composite plastic packaging bag is a combination of multi-layer materials, the bag is relatively thick, and PET is only resistant to high temperatures, so such bags can withstand relatively high temperatures, usually reaching a high temperature of 200 degrees to seal the bag;

Of course, the thicker the bag, the higher the temperature is. When packaging, it must be tested and then sealed in batches to avoid unnecessary troubles during use.

The most important thing in the sealing of plastic packaging bags is temperature control. After the temperature is controlled, the sealing is smooth, beautiful and will not be damaged. Therefore, when sealing, be sure to test a suitable temperature, and be sure not to rush into mass production to avoid waste.
