PVC is known for its clarity and strength, polyolefin is versatile and food-safe, while polyethylene is used for heavy-duty applications. Understanding the differences will help you choose the right type for your needs.

What Are the Thickness Options?

Different shrink films have varying temperature requirements for optimal shrinking. Knowing the shrink temperature is essential to ensure compatibility with your shrink-wrapping equipment. Ask the supplier for the recommended temperature range and make sure your equipment can accommodate it.

What Is the Shrink Rate?

The shrink rate indicates how much the film will shrink when heat is applied. It’s important to choose a film with a suitable shrink rate for your products. Films with a higher shrink rate provide a tighter fit but may be more challenging to work with. Understanding the shrink rate will help you achieve the desired packaging results.
