2. Not the thicker the better

In order to sell more stretch film, some stretch film manufacturers make the film very thick, so that the use of customers will increase, and they will earn more money. Once we purchase, it will cause great waste to the company.

3. Stretch Scale

Why is the stretch ratio a very important parameter? Because the core performance of the machine stretch film, the high stretch ratio stretch film means more saving and energy saving, but the high stretch ratio stretch film must be used on the same stretch ratio pre stretch film rewinding machine to better show its performance. 

4. Retraction force

The retraction force of the stretch film is a very important technical parameter. The retraction force is not fully reflected without sufficient stretching, so even the high-quality stretch film does not reflect its advantage
