What are the factors affecting PE heat shrinkable film

The products made by PE heat shrinkable film manufacturers can be used in many industries. It has many advantages. What factors will affect the quality of the product. Now let's take a closer look? In fact, it affects the quality of the product. The factor is the heating temperature: Affected by the PE material, the heating temperature will affect the strength of the heat shrinkable film, thereby affecting its quality. Generally speaking, the temperature should be controlled at about 160 degrees Celsius during the actual heating process; if it is high Or low levels will have varying degrees of impact on it. The second is the heating time. Under the premise of ensuring the temperature and pressure, the longer the time, the stronger the bond between the seals and the better the performance; but if the time is not accurate, then wrinkles will appear. Problems such as pleats and poor flatness; thereby affecting its overall aesthetics. In order to ensure its good strength, reasonable pressure is also very necessary. Generally speaking, reasonable and uniform pressure helps to reduce the rate of bubble generation, thereby increasing the overall yield rate and reducing unnecessary losses for the enterprise; so Reasonable pressure is also an important factor affecting the strength of PVC heat shrinkable film.
