Shrink wrap machines are machines used to shrink wrap film around products to create a protective package. The shrink films are usually made of polyethylene or PVC and are placed around the product to be packaged. The shrink equipment then heats the film using heat and air currents to shrink it to fit snugly around the product. Shrink lines are used in a variety of industries, including food, beverage, cosmetics, electronics and automotive. They offer a fast and efficient way to package and protect products while providing an attractive and appealing package. There are different types of shrink machines, such as chamber shrink machines, tunnel shrink machines and L-bar shrink machines. Each type has its own advantages and disadvantages and is suitable for different types of products and packaging. Shrink lines are also capable of processing different film thicknesses and types to meet the requirements of different industries.
