Bag making machine PVC bag making machine is a machine specially used for manufacturing PVC plastic bags, belonging to a kind of flexible packaging production equipment. The bag making machine is the last process in the production and processing of plastic flexible packaging. If the quality of the bag is not high and unqualified, it will lead to the previous process, which will waste time and cause unnecessary losses. PVC bag mechanism bags are often heat sealed, so in the bag making, the quality of the bag and the quality of the heat seal are related to the entire production, packaging and other aspects. Below, analyze what problems will be encountered during heat sealing in the bag making process?
    1. The heat sealing of the bag making machine is not complete
    Cause: The film has poor anti-fouling heat sealability.
    Solution: Choose a film that is resistant to contamination and heat sealability.
    2, the contour of the heat sealing surface of the bag making machine is not clear
    Cause: The cooling time is too short.
    Solution: Prolong the cooling time.
    Cause: The cooling plate is not in good contact.
    Solution: Adjust the cooling plate.
    Cause: The heat seal knife is blunt.
    Solution: Replace the heat seal knife.
    3, poor heat seal strength
    Cause: The heat sealing conditions are not appropriate.
    Solution: Adjust the heat sealing conditions according to the material of the film.
    Cause: There is a problem with the inner seal film.
    Solution: Increase the thickness of the inner seal film.
    Cause: Some substances such as dust adhere to the hot cover.
    Solution: Check the processing level of the hot cover.
