A shrink wrap machine is a device used to package products securely by applying a plastic film that shrinks tightly around the item when heat is applied. This process protects the product from dust, moisture, and damage during storage and transportation. Shrink wrap is commonly used in various industries, including food, electronics, and retail. The machine typically consists of a film dispenser, a heat source, and a sealing mechanism. Operators place the item on a conveyor belt, where it is wrapped in the plastic film. After sealing, the heat source activates, causing the film to shrink and conform to the shape of the product, ensuring a snug fit.
