Why "Easy Tear" matters: the science behind smarter food packaging.

2026-03-20

Have you ever opened a snack package and the plastic was extremely difficult to tear down the middle? 

You are definitely not alone. As packaging technology continues to evolve, one main question is still the same: why is it still so difficult to open a simple snack package?

We at Changsu believe that all packaging should be easy to open each and every time. This belief is what led us to develop TSA (Tear-Seal Advanced) film – a new high-performance solution that is revolutionising the way consumers interact with flexible packaging.

What makes TSA unique?

Traditionally, most packaging requires a pair of scissors or your teeth to tear through. TSA completely changes this. It is an easy to tear nylon film that creates a pre-determined straight tear path — each and every time. There will no longer be jagged edges. No more sudden spills. Simply a clean, dependable, consistent open. Our easy to tear nylon film will provide consistent performance regardless of the type of packaging being used — whether it is a snack portion size or a larger family size portion.

This easy to tear nylon film is not just easy to open; it is also a tear-resistant easy open packaging film. Meaning that it provides balance between strength and convenience. It is strong enough to protect the product inside during transportation and store shelving, and is weak enough to easily tear by simply pulling it apart. As a tear-resistant easy open packaging film, it provides reliability that both manufacturers and end users can rely upon.
