Heat Shrinking Machine: Innovator in Product Packaging Industry

The heat shrinking machine wraps the product with heat shrinkable film and heats it to shape it. With its dual capabilities of "sealing protection" and "visual enhancement", it has become a standard packaging equipment in the food, medicine, electronics and other industries. Its core technology is to use the thermoplasticity of polymer materials - when the film is heated to 120-180℃, the molecular chain is rearranged from a disordered state to a compact structure, and the shrinkage rate can reach 30%-70%, thus closely fitting the product contour.

The working principle of the heat shrinking machine is based on the thermal responsiveness of material science. Taking PE film as an example, the memory effect formed by its biaxial stretching process can shrink and form in a short time under the infrared radiation of a quartz tube or stainless steel heater, and perfectly fit the special-shaped surface. The sealing layer formed after shrinkage can block the penetration of water and oxygen, extending the shelf life of the drug by 20%; for fragile products such as glass bottles, its cushioning performance can withstand a 1.5m drop impact. Compared with traditional carton packaging, the cost of PE film is reduced by 40%, and the automated production line reduces labor input by 60%. If wrinkles appear after shrinkage, check the uniformity of hot air circulation or adjust the conveyor belt speed.
