The people that used shrink machine all know, shrink machine has three institutions:heating mechanism, blowing mechanism, conveying mechanism. The heating mechanism of the temperature to shrinking machine, according to the different film, shrink temperature adjusted accordingly.
  For ordinary POF, PVC film shrink power setting in the 5~20kw,according to the thickness of the film to the device temperature and conveying speed, air flow rate,the size of the temperature to set. If the product that cannot permit high temperature can use low temperature, shrinkage using thin film. Shrink film thickness if temperature need heightening, shrink machine power also need to choose the larger.Product conveying speed temperature corresponding to high, and reduce, increase transport air temperature decreased, whereas elevated. Power PE shrink film is in 160 degrees ~200 degrees.
