Details use of stretch wound film

What are the usage details of stretch wound film? Stretch wound film can also be referred to as stretch film for short. It is a packaging material that is frequently used in the logistics industry now. If you want to use stretch wound film better, you must pay attention to the details of its use. So today I will collect some questions about this aspect and introduce it to you, I believe you can use it better.
 
Users also need to pay attention to the following details when using stretch film products:
1. When users use stretch wrap film products, they should first ensure that the cutting tools we use, the sawing machine is equipped with high-speed steel saw blades on the sawing machine.
 
2. Pay attention to carefully check the pressure resistance and tightness of various interfaces of various membrane products after using various connection methods to form a system. The test pressure value is generally a multiple of the system working pressure.
 
3. Farmers need to test the stretch film before cutting the stretch film. The stretch film pressure test includes the film product pressure test and the film channel system pressure test, and the film product pressure test is to check the compressive strength and tightness of the film product itself. sex.
 
Stretching is the ability of the stretch film to produce elastic elongation after being stretched. If the quality is good, the length will be extended after stretching, and within a certain limit, it will not break. This is a feature of its own, with such tensile properties, can better packaging items.
 
Toughness refers to the comprehensive properties of film resistance to puncture and tear. The risk value of the degree of tear resistance must be horizontal, that is, perpendicular to the machine operation direction, because tearing in this direction will loosen the package, and even if the longitudinal tear occurs, the package can still remain firm. Therefore, the better the toughness of the stretch film, the better the quality.

The difference between machine stretch film and hand stretch

图片
  With the continuous growth of the stretch film market, more and more products are packaged with stretch film. At present, stretch films on the market mainly use LLDPE raw materials.  Both machine stretch film and  hand stretch film  have good tensile properties , strong shrinkage and high transparency, good puncture resistance, good self-adhesion and low unit consumption. Whether it is used for collective product packaging or pallet packaging of goods, it can achieve the purpose of moisture, dust, and waterproof, reducing labor, improving efficiency and reducing costs. Generally speaking, there are two types of stretch films on the market, machine stretch films and hand stretch films. 1. Machine-use stretch film is to put the objects to be wrapped in the middle of the turntable. Through the pneumatic turntable motor, the turntable is driven to rotate, and the stretched film is naturally and evenly wrapped on the surface of the object. At the same time, the lifting ...
