The main reasons for the brittleness and brittleness of the seal during the operation of the paper straw slitting machine are as follows:
1. The heat sealing temperature is too high.
2. The pressure of the paper straw slitting machine is too large.
3. The heat sealing time is too long.
4. The edge of the upper sealer is too sharp or the PTFE covered is damaged.
5. The silicone rubber sealed at the bottom of the paper straw slitter is hard.
6. During the machine compounding and curing process, a part of the adhesive penetrates into the film. Due to the influence of the penetration of the adhesive, the toughness of the substrate decreases and the brittleness increases.
7. After the plastic composite packaging bag is cooled and placed, the heat sealing strength increases, and it also tends to become brittle.
