9.What Is The Working Principle Of Heat Shrink Wrapping Machine?

Place your products on the conveyor system, which moves it to the packaging area;

The conveyor system usually consists of belts or rollers, and its speed can be adjusted to accommodate your products of different sizes and shapes;

Set a roll of shrink wrap film on the reel and pulled under the sealing strip. After wrapping your product, all edges are sealed using the sealing strip;

The sealed product is then fed into the hot air system, which will heat your film by blowing hot air at it;

The heat sealing system uses a heating element to directly heat the film;

Once the film is heated, it begins to shrink. The speed and degree of film shrinkage depends on the heat you applied, as well as the material and thickness of the film;

The film shrinks first from the sides of the packaging machine and then extends to the top and bottom of the product;

When the film is fully shrunk and conforms to the surface of your product, the packaging process is complete;

The heat shrink wrapping machine's conveyor system will move the packaged product out of the machine for further processing or shipping.
