What factors affect the heat sealing strength of bag making machine

1、 Heat sealing material
1. Different heat sealing materials require different heat sealing strength.
2. The density, polymerization method and thickness of materials all affect the heat seal strength.
3. The processing methods of heat sealing materials are different.
4. Additives in heat sealing materials also affect the heat sealing strength.
5. The longer the material is stored, the more additives precipitated, which will lead to the decrease of heat seal strength.
2、 Bag making technology
1. Insufficient heat seal pressure will make it difficult to fuse the heat covers together.
2. Improper heat seal temperature.
3. Improper heat sealing time.
4. Cooling time also affects the strength and appearance of the heat seal.
5. The more times of hot pressing, the higher the strength of heat seal.
These are the factors that affect the heat seal strength of Bag Making Machine.
