Crosslinked vs. Non-Crosslinked Shrink Film: What’s the Difference and Which Should You Use?

Shrink film looks similar across the board, but performance can vary a lot depending on how it’s made.

One of the biggest differences is crosslinked vs. non-crosslinked film. Choosing the right one affects durability, appearance, speed, and cost.

Here’s how they actually compare.

What Is Crosslinked Shrink Film?

Crosslinked shrink film goes through a process that bonds the polymer chains together. That changes how the film behaves under heat and stress.

What That Means in Practice

• Stronger film. Better resistance to tearing and punctures
• Higher shrink force. Tighter, more secure wrap
• Handles higher temperatures. Ideal for high-speed lines
• Better seal strength. More consistent performance

When It Makes Sense

Crosslinked film is typically used when:

• You’re running high-speed packaging equipment
• Products need strong protection during shipping
• You want a clean, tight retail finish
• Downtime or film breaks are costing you money

What Is Non-Crosslinked Shrink Film?

Non-crosslinked film doesn’t go through the same bonding process, so it stays more flexible and softer.

What That Means in Practice

• Lower shrink force. Looser wrap
• More flexible film. Better for delicate products
• Lower heat tolerance
• Lower cost

When It Makes Sense

Non-crosslinked film is usually the better option when:

• You’re packaging lightweight or delicate items
• You don’t need a tight, high-tension wrap
• You’re running lower-speed equipment
• Cost is the primary driver

Side-by-Side Comparison

What Most Businesses Get Wrong

A lot of companies default to cheaper film to save money.

But if you’re dealing with:

• Film breaks
• Poor seals
• Inconsistent wraps
• Product damage

You’re likely losing more than you’re saving.

In those cases, upgrading to crosslinked film usually improves uptime and overall efficiency enough to justify the cost.

The Bottom Line

There’s no “best” option. It depends on your operation.

• Go with crosslinked film if you need durability, speed, and a tight finish
• Go with non-crosslinked film if flexibility and cost matter more than performance

The right choice comes down to your product, your equipment, and your production goals.

Need Help Choosing the Right Shrink Film?

If you’re not sure which film fits your setup, it’s worth dialing it in. The wrong film can slow your line down or hurt product quality.
