Why does PE stretch film have glue residue?

There are many types of PE stretch films on the market, such as mobile phones and other electronic products, and food preservation. PE stretch film is a very important protective product in the industry. It can avoid the abrasion and pollution of the product during transportation, and it plays a very important role in the industry. However, we sometimes find that there will be residual glue after the PE stretch film is used. What is the reason?
 
1. To check whether the high temperature resistance data of the used PE stretch film meets the production request, the temperature resistance is usually 210 degrees-260 degrees.
 
2. Is the temperature data of the production line within the technical request scale? Is the temperature too high? Check if the temperature sensor is normal.
 
3. The product's own quality problems, whether it is heated and cured strictly according to the pressure-sensitive adhesive baking data during the coating and production process, the curing time is not enough or the coating line speed is too fast, which will cause glue, primer glue, The three substrates cannot be related to each other.
 
4. After the product is coated, the semi-finished product should be allowed to stand for 2-3 days before it can be used for rewinding and slitting. The intention is to make the glue and the substrate fully contact, and the glue is solidified in its natural state.
 
The PE stretch film is made of polyethylene terephthalate as a raw material, which is made into a thick sheet by an extrusion method, and then biaxially stretched to make a stretched film material. It is a colorless, transparent, glossy stretch film with excellent mechanical functions, high rigidity, hardness and toughness, friction resistance, puncture resistance, and low temperature and low temperature resistance. It has excellent chemical resistance, oil resistance, and air tightness. It is one of the commonly used barrier composite stretch film substrates.
 
PE stretch film is a semi-transparent, shiny, and soft texture stretch film. It has excellent chemical fluctuation, heat sealability, water resistance and moisture resistance. It is rare that it is transparent and has the characteristics of pe stretch film. It has strong stretching function, elasticity, environmental protection, non-toxicity and no harm to the situation.

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 ...
