A hot air gun is a versatile tool that can be used for a variety of purposes, including shrinking packaging film around juice and water bottles. It works by blowing a stream of hot air that melts the plastic film, causing it to shrink and conform to the shape of the bottle.
Hot air guns are a popular choice for packaging juice and water bottles because they are relatively inexpensive, easy to use, and efficient. They can also be used to shrink wrap other types of products, such as food, electronics, and pharmaceuticals.
