There are a number of different kinds of stretch film, designed specifically for various different applications. The range of stretch film are designed to deal with common problems like load weight, load size, and so on. Then there are other special stretch films which address less common problems like static reduction, UV resistance, etc.
The main differences between the various kinds of stretch film machines is the way in which they work and the materials that they are made out of. If you are looking for a machine to create a film to be used mainly around the house or perhaps to cover some decorative items then you will probably want a machine that is built more for practical use than purely for aesthetics. If you are looking for a machine that can be used to produce large rolls of film for your company then you may well want to invest in a stretch film machine that has all sorts of different features and capabilities.
One of the main features of any stretch film machine is the lamination properties that it possesses. It should have a strong enough adhesive property to adhere to most kinds of substrates. The most common test to determine this property is known as the adhesion test. In this test, a certain stretch film is placed on a portion of a certain material and a magnetic force is applied to the item. When the force is removed from the item, then the lamination has been damaged.
