Thickness of Stretch Film

Stretch film(Stretch film) has high tensile strength, tear strength, and nice self-adhesive, so that it can make the object wrapped into a whole, to prevent the collapse of the transport scattered. https://baijiahao.baidu.com/s?id=1749004415401296989

When choosing stretch film, there are many customers who will choose thicker stretch film because they think that thicker stretch film has better quality.This also leads to many people have questions.

Is really stretch film the thicker the better?

In fact, most clients will choose thicker stretch film because they think that the thicker the better and the strength, the safer. However, the authentic situation is the staff of the factory in order to ensure that the stretch film is not pulled off by the machine, forced to make its thickness thicker. It is actually a helpless choice. From factories’ perspective, the production of thicker stretch film, on the one hand, the production equipment and production precision requirements will be reduced. On the other hand, the client’s use of stretch film increased, the cost will increase accordingly. If the thickness of the stretch film is larger, it will be more difficult to stretch, especially the hand stretch film, which will reduce the work efficiency.

Secondly, the thickness of the stretch film is larger, the viscosity is also lower. The viscosity of the stretch film is its own characteristics, in the production, after adding DOV and other plasticisers formed. Stretch film that is too thick has different requirements in the process and changes in the production formula. This lowers the self-adhesion of the stretch film and also reduces itsquality. For instance, the common hand stretch film on the market is 0.02mm thickness. And the normal thickness of the machine stretch film is 0.025mm. Every increase in the thickness of 0.01mm, the mechanical properties of the stretch film will be a corresponding decline of about 5%.

So stretch film is not the thicker the better. We ultimately need to combine with actual use of stretch film to determine the thickness of the film purchased.
