While there are many different types of packaging materials that can be used in the competitive world of manufacturing and retail; shrink wrapping film is among the most versatile and increasingly popular packaging option for many industries. From protecting perishable foods and beverages to preserving packaged Consumer goods, and industrial items; shrink wrapping film meets all of your business’ packaging needs by providing both strong protective qualities and a visually pleasing appearance.
In this article we’ll discuss what shrink wrapping film is, why you would want to use it, where you might apply it, and how you could select a shrink wrapping film that best fits your company’s packaging needs.
What is Shrink Wrapping Film?
Shrink wrapping film is a flexible plastic sheet made specifically to wrap snugly around a product once heated. When applying heat to the shrink wrapping film either through the use of a heat gun or a heat tunnel, the film contracts at an even rate and forms a sealed package that is difficult to open.
Some common plastics used to manufacture shrink wrapping film include:
- Polyolefin (POF)
- Polyethylene (pe)
- Polyvinyl Chloride (pvc)
Depending upon the intended use for your products, each of these plastics have their own strengths and weaknesses.
Advantages of Using Shrink Wrapping Films
Protects your Products
Perhaps One of the greatest advantages of using shrink wrapping film is to keep your products free of contamination. By sealing your products into a tight-fitting package, the risk of dust, moisture, dirt, etc. Coming into contact with your products is greatly diminished. This helps to preserve your product’s quality until it reaches the end user.
Improves your Product Presentation
