How Does Heat Shrink Wrap Machine Work?

heat shrink wrap machine

Heat shrink wrapping machine is a common packaging equipment widely used in various industries. It uses heat energy to shrink-pack plastic films on the surface of objects to achieve protection, sealing and aesthetic effects. This article will briefly introduce the heat shrink packaging machine working principle.

The heat shrink wrap machine working principle is based on the principle of heat shrinkage, that is, when heated, the plastic film will shrink and wrap tightly around the surface of the object. This principle is realized by controlling the heat source and heat transfer method.

Here is the heat shrink wrap machine youtube video working process in our factory for your reference!!

First, the shrink wrap machine unwinds the plastic film from the roll and delivers it to the packaging area via a conveyor belt. The objects are then placed on a conveyor belt ready for packaging.

Next, the shrink wrap machine heats the plastic film through a heat source, usually a hot air or infrared heater. When heated, the plastic film becomes soft and has some plasticity.

Once the plastic film is heated to a certain temperature, it will begin to shrink. This is because heating makes the molecules inside the plastic film more active, causing the plastic film to shrink.

When the plastic film shrinks, it conforms tightly to the surface of the object and creates a tight package. This kind of packaging protects the object from the external environment, such as dust, moisture and bacteria.

Finally, the heat shrink wrap machine sends the packaged objects out through the conveyor belt. The entire process is fast and efficient, and can accommodate objects of various sizes and shapes.

To sum up, the heat shrink wrap machine heats the plastic film to shrink and tightly wrap it on the surface of the object to achieve protection, sealing and beautiful effects. The working principle of this machine is simple and effective, providing efficient packaging solutions for various industries.
