A shrink wrapper is a type of packaging machine that uses heat to wrap products in a plastic film. The process involves placing the item on a conveyor belt, where it is then covered with a plastic sheet. Once the item is enclosed, heat is applied, causing the plastic to shrink tightly around the product, providing a secure and protective seal. This method is commonly used in various industries, including food, pharmaceuticals, and consumer goods, to ensure items are protected from dust, moisture, and tampering. The shrink-wrapping process is efficient and helps maintain product integrity during storage and transportation.
