How to Choose the Right Thickness of Crosslinked POF (15mic, 19mic, 25mic)

Do you want strong and clear packaging? Crosslinked POF shrink film is a great choice. It is stronger than normal POF film. But which thickness is best for your product? The most common sizes are 15 micron, 19 micron, and 25 micron. This simple guide will help you pick the right one.

What Do the Numbers Mean?

• Micron (mic) = how thick the film is

• 15mic = very thin (like 60 gauge)

• 19mic = medium thin (like 75 gauge)

• 25mic = thicker and stronger (like 100 gauge)

Thinner film costs less and looks clearer. Thicker film is stronger and protects better.
