What is the cause of the poor shrinkage of Jiangmen automatic sealing and cutting shrinking machine

What causes the poor shrinkage of Jiangmen automatic sealing and cutting shrinking machine The heat shrinkable machine is also known as the shrinkable machine or the heat shrinkable packaging machine This machine mainly uses the heating principle to heat and shrink the film attached to the product surface Now many industries are using the heat shrinkable machine, such as beverage, mineral water, cosmetics, etc., but in the process of our shrinkage, we are bound to encounter the situation of bad shrinkage What is the cause ? [Elida] brief introduction: 1 The temperature set by the heat shrinking machine is not enough In fact, the working principle of the heat shrinking machine is relatively simple, that is, the matching of speed and temperature When the temperature is low, the product surface will appear wrinkles If the temperature is high, the film will be scalded According to the experience of the technical staff of aisun, generally speaking, the POF film can be used at a temperature of about 130 degrees, while the PE film can be used at a temperature of about 170 degrees 2 The size of heat shrinker channel is not suitable The size of furnace channel is not suitable for two situations, one is that the furnace channel is too large, the other is naturally that the furnace channel is too small The situation that the furnace channel is too large is that the product receives less temperature, most of the heat is three, so it is necessary to increase the heat shrinkable packaging machine to a very high temperature to shrink better If the furnace channel is too small, the film will be stuck on the inner wall of the furnace channel, which will be burned 3 There were no punctures in the contractile membrane This situation is mainly aimed at the situation that POF film is fully wrapped When the user's products need to be fully wrapped, some holes must be punctured on the surface of the shrinking film, so that when the automatic heat shrinkable packaging machine is retracted, the gas in the film can be emitted through the holes, otherwise the gas will be in the film, and the film will bulge 4 Speed mismatch Different products contracted by users require different conveying speeds There is no standard value for this speed for reference It is mainly because customers need to carry out tests during use Generally, after several tests, good results will appear basically 5 The quality of shrink film is too poor The shrink film used in the heat shrinking machine needs to meet certain requirements If the quality of the shrink film is too poor, the effect of shrinkage must be bad, either there are wrinkles or they will burst.
