Heat sealing and cold cutting bag making machine is a machine for making all kinds of plastic bags or other material bags. Its processing range is all kinds of plastic bags or other material bags of different sizes and thickness specifications. Generally speaking, plastic bags are the main products.


What factors affect the heat sealing strength of the heat sealing cold cutting bag making machine?


First, heat sealing materials


1, different heat sealing materials, the required heat sealing strength is also different.


2, the density of the material, polymerization method, thickness and so on will affect the heat sealing strength.


3. The processing methods of heat sealing materials are different.


4, heat sealing materials in the additive will also affect the heat sealing strength.


5. The longer the storage time of the material is, the more additives are precipitated out, which will lead to the decrease of heat sealing strength.


2. Bag making process


1. Insufficient heat sealing pressure will make it difficult to fuse the hot cover together.


2, the heat sealing temperature is not appropriate.


3, the heat sealing time is not appropriate.


4. Cooling time will also affect the strength and appearance of heat seal.


5, the number of hot pressing, the more times, the higher the heat sealing strength.


These are the factors that affect the heat sealing strength of the heat sealing cold cutting bag making machine.
