How to seal the compound bag?

2022-09-26

Compound bag sealing process: 1. Prepare a useless packaging bag in advance and cut it into a square or square. 2. Fold it up to solve, and the area it is facing will be flattened. 3. Light the candle. 4. Insert the cutter head into the area to be sealed, be sure to stick tightly. 5. Press it lightly, get close to the flame of the candle, and move it quickly to make the melted plastic stick together quickly. All other sides are solved the same.

The general composite bag sealing compressive strength is 22.6-34.3N/15mm, which is the variable value of most composite bags. Naturally, there are some unique requirements that may not have this category. In fact, you need to carry out inspection on your raw materials. The heat sealing time is also a primary condition that affects the heat sealing compressive strength and appearance flatness of the composite packaging bag. Under the same heat-sealing temperature and heat-sealing working pressure, the longer the heat-sealing time is, the more sufficient the heat-penetrating layer is welded and the stronger the connection is. .
