What are the reasons for the bad contraction effect of the heat shrink packaging machine?

The working principle of the thermal shrink packaging machine is to use heating method to heat the film outside the product, so that it tightly shrinks on the surface of the product packaging, but according to many customers, the thermal shrink packaging machine often encounters the effect of contraction in the process of contraction is not very good, the sealing is uneven, the film is damaged, the appearance of stuttering and other situations occur. So what are the reasons for the poor effect of the low-impact heat shrink packaging machine in the shrinkage process? Here is a detailed introduction for you.

1, the speed is not appropriate. The user's heat shrink packaging products are different, the demand of the transport speed is different, this speed does not have a standard value for reference, mainly the customer needs to carry out experiments when using, generally through a few experiments, the basic will show a better effect.

2, heat shrink packaging film puncture. This situation is mainly for the pof film full package situation, when the user's product needs full package, the surface of the heat shrinkable packaging film must be pierced with some holes, so that the gas inside the film can be emitted through the small hole when the heat shrinkable packaging, otherwise the gas is in the film, it will show the situation of the film bulge.

3, the quality of the film is too poor. The heat shrink packaging machine for the heat shrink packaging film needs to meet certain requirements, if the quality of the heat shrink packaging film is too poor, then the role of the heat shrink packaging must be bad, either there are folds, or it will burst.

4. Not enough temperature. The working principle of the packaging machine is actually relatively simple, that is, the matching of speed and temperature, when the temperature is low, the appearance of the product will show wrinkles. And if the temperature is high, it will show the situation that the film is scalded. Generally, pof film can be used at a temperature of about 130 degrees, while PE film (PE heat shrink packaging film packaging machine) can generally use a temperature of about 170 degrees is more appropriate.
