PVC heat shrinkable film is one of the commonly

PVC heat shrinkable film is one of the commonly used shrink films. Door factories and aluminum material factories basically use it for packaging. Its shrink temperature is low, and the shrinkage film can be complete at about 80-100 degrees, and it shrinks quickly and shrinks. Good, it will not affect the surface paint of the door and aluminum;

PE heat-shrinkable film feels soft to the touch, but requires a relatively high shrinkage temperature. It takes 180-200 degrees to shrink. It is often used for cluster packaging. It is used for combined packaging of irregular shaped items or commodities. It meets the functions of moisture-proof and dust-proof, anti-touch, and transparent display, and can increase the attractiveness of the product. Such as: whole package of mineral water drinks;

POF heat-shrinkable film, generally the conventional thickness is 3C, can not do 4C, generally use it to wrap more delicate things, the shrinking temperature is a little higher than PVC, about 120-150 degrees, and the price is relatively higher than that of PVC. , But if it is made into a bag, the position of the pressure port is not as good as that of the PVC heat shrinkable film.
