Do you know what the glue is? Why is it in the stretch membrane?
Is a term used in film, stretch film, its main purpose is stretch packaging machine, to fix a heap of material to a tray is main to do it, its purpose is to form a unitary or single, reliable, and can transport objects, the destination, it to the desired state. Usually the stretch film is made of LL or linear low density polyethylene, which has good weight, cost and strength. Not long ago, we wrote this article, and in this article, there is the process of making a stretch film.
Fpc1 extruder add various compounds, in general are added to the stretch film, making the required performance characteristics can be offered, and you can also make it easier to deal with the application of the film machine, stretch packaging. The binder is one of the key additives.
So, let’s see what the viscosities is?
In the extrusion process, the adhesive is a kind of binder, which is used as the addition layer in the stretch film (to remove the solid polymer, so as to melt and form the membrane or tube). The mechanism that transports adhesion to film is this binder.
So, what is break-even?
“Sticky” is the film’s “sticky” property. We can put it in other words, the layer that attaches to the top and the upper layer is a membrane.
Used to develop an adhesive layer can be applied to a movie, is tackier, film is also at the same level, the two sides or differential levels on both sides of the film, cause different degree of more and less binding, will hold down each side.
