The automatic Sleeve Shrink Wrap Machine is made to wrap heavy products with thick film. The finished packaging has two open ends on each side which are referred to as “bullseyes”, so we also call the machine Automatic shrink bundling machines.Purposes of the shrink machine are; – To make the smallest packages a larger and more complete package. – To ensure that a product is packaged and kept clean. – To ensure that the seal is maintained for the product's lifetime.When heat is applied to shrink wrap, it creates a very tight seal. This plastic seal then fully protects the shrink wrapped contents. Once sealed, the items are no longer vulnerable to the damage that can be caused by dust, dirt or moisture.
