Nowadays, many industries can use stretch wrapping film. From this, we can see that the demand for stretch wrapping film is very wide. Mingye stretch film is made of high-quality materials, but you should pay attention to the cutting method and professionalism when cutting. If you use the wrong method to cut the stretch film, it will affect the use of the stretch film and the integrity of the stretch film.

So how to cut the stretch wrapping film:

First of all, the cutting of stretch wrapping film is divided into manual cutting and saw cutting. The main tool for manual cutting is manual hacksaw. Manual hacksaw has two ways of moving and fixing, both of which are composed of saw bow and saw blade. Sawing machine cutting is to install a high-speed steel blade on the sawing machine, which can cut various metal films and plastic films below DN200mm. Portable electric film sawing machines are often used on the construction site, and the maximum cutting diameter is 550mm.

The pressure test of the stretched film includes the pressure test of the film product and the pressure test of the film channel system. The pressure test of the film product is to check the compressive strength and tightness of the film product itself. It is usually a multiple or a multiple of the nominal pressure of the corresponding film product. The specified value corresponding to the membrane channel level and membrane diameter is used as the test pressure value.

When the stretched film is cut, harmful substances in the water will be removed to ensure the normal operation of the equipment. Therefore, various food-grade or sanitary-grade PE stretched films with special membrane element structures have also begun to be used in a wide range of applications.
