A Heat Gun for packaging is a handheld device that blows hot air, used mainly for shrinking plastic film around products. It's commonly used in shrink wrapping, where the heat causes the plastic film to tightly wrap the item. To use it, you place the shrink film over the product and move the heat gun over it evenly. The heat shrinks the film, giving a neat, secure, and professional packaging finish. It helps protect products from dust, moisture, and damage. Heat guns are widely used in packaging electronics, boxes, bottles, gift items, and more. It's easy to use, lightweight, and perfect for small businesses and home-based packaging work.
