Shrink wrap, also referred to as shrink film, is an incredibly versatile and widely-used polymer plastic packaging material specifically designed for wrapping and packaging various goods. This exceptional packaging solution provides a secure and snug fit around the covered item when heat is applied.
Versatile Polymer Plastic Packaging Material
The three main types of Shrink Wrap commonly used as a packaging material are Polyvinyl Chloride (PVC), Polyethylene (PE), and Polyolefin (POF). Each Shrink Wrap has slightly different characteristics, like thicknesses, clarities, strengths, and shrink ratio, making these materials suitable for specific applications.
To apply shrink wrap, a couple of popular methods are commonly used. One option involves using an electric or gas heat gun with a heat sealer. Directing the heat towards the shrink wrap contracts and conforms tightly to the product’s shape, ensuring maximum protection and presentation.
Another commonly employed technique involves passing the product wrapped in shrink wrap through a heat tunnel on a conveyor system. This efficient method applies heat uniformly to the material, resulting in consistent and professional-looking packaging. Find out more here to learn more about shrink wraps or shrink films.

Polyvinyl Chloride (PVC)
PVC shrink wrap is widely recognised for its excellent clarity and durability. It provides exceptional protection against moisture, dust, and other external elements. With its high shrink ratio, PVC wrap can achieve a tight fit around products of varying shapes and sizes. It is commonly used in packaging products such as electronics, software, and consumer goods, where visibility and product appeal are essential.
PE shrink wrap is known for its versatility and affordability. It is available in various thicknesses, making it suitable for a wide range of applications. PE wrap offers good puncture resistance and clarity while providing reliable protection against moisture and dirt. It is frequently utilised for packaging food items, beverages, pharmaceuticals, and other consumer goods.
POF shrink wrap is renowned for its strength, clarity, and versatility. It is a popular choice for packaging products that require a high level of protection and security. POF wrap has excellent tensile strength and tear resistance, making it ideal for bundling multiple items. It provides a consistent, glossy finish and is often used for packaging boxes, promotional items, and more.
