Sealing method of heat shrinkable film

According to different sealing methods, the packaging effect of heat shrinkable film is different for different packaging products. There are many types of sealing methods. Next, the heat shrinkable film manufacturer will introduce the sealing method of heat shrinkable film hot pressing. Let's take a look. Take a look: 　　1. Heat the two contact surfaces of the heat shrinkable film to make it in a melted shape, and then increase the pressure to make the contact surfaces firm and integrated, which can achieve a series of effects such as packaging and beauty.　　2. Temperature is a factor that affects the sealing effect. If the temperature is too high, it will easily cause deformation of the contact surface and affect the appearance. If the temperature is too low, it will easily cause problems such as lax sealing.　　3. The heat shrinkable film manufacturer tells everyone that resistance heating and pulse heating are two commonly used methods for heat compression sealing, as well as ultrasonic heating, high-frequency current and other methods. The above is the sealing method of heat shrinkable film hot pressing. I hope to deepen everyone’s understanding of the product. This issue of heat shrinkable film manufacturers’ sharing is here. The company’s main heat shrinkable film is of good quality and reasonable price. If necessary, Welcome to contact us. Previous: No more
