When it comes to stretch films, there’s a wide variety available: different thicknesses, different additives, different resins, and different extrusion methods. With all of these differences, it can be difficult to determine which stretch film is best for your application.

In today’s post, we’re going to take a closer look at these two options.

When it comes to selecting a stretch film, there are a nearly infinite number of possibilities. There are varying thicknesses, pre-stretch qualities, assorted additives, and extrusion methods.
