No matter how good the bag is, a poor seal can also affect the appearance of the bag. So what should you pay attention to when sealing plastic bags?
1: The sealing method of single-layer plastic packaging bags.

Therefore, the temperature must be checked repeatedly when sealing. The direct temperature will not burn the bags, and the appearance of the bags is smooth. is a suitable temperature. Typically such bags are foot sealers.
2: The sealing method of the multi-layer composite packaging bag.
The multi-layer composite plastic packaging bag is composed of multiple layers of materials. The bag is relatively thick and PET is resistant to high temperature, so such a bag can withstand relatively high temperatures. Generally, the high temperature of 200 degrees can seal the bag. Of course, the thicker the bag, the higher the temperature. The higher the temperature, the inspection must be done before batch sealing to avoid unnecessary trouble during use.
The most important thing in the sealing of the packaging bag is temperature control. The temperature control seal is smooth, beautiful and will not be damaged. Therefore, the sealing must check the appropriate temperature, and do not worry about mass production to avoid waste.
