What Are The Main Reasons For The Quality Of The Wrapping Film?

As the stretch film is more and more popular, the competition of the stretch film in the market is becoming more and more fierce, and there are more and more types of stretch films. We may be a little confused when choosing, and generally When we buy stretch film, we all want to choose good quality stretch film. Before that, we need to understand the key to the product quality of stretch film manufacturers. The following editor will simply discuss this problem with everyone Introduce the reasons for the quality of the wrapping film, and hope to help everyone!

1. The shrinkage stress of the wrapping film, also known as the bearing force retention, refers to the level maintained after the increase in the amount of the wrapping film during the entire process of stretching the product;

2. The ductility of the wrapping film refers to the comprehensive ability of the wrapping film to resist piercing and resilience. The resilience working capacity is only for the resilience level of the plastic film under the condition of being exposed after the support force;

3. The self-adhesion of the wrapping film, the adhesion of the wrapping film and the plastic film after touching each other, can make the packaged product firm and not loose during the whole process of using the stretched coiled product. Self-adhesion will be endangered by a wide variety of external independent variables;

4. The tensile force of the wrapping film refers to the tensile force that the wrapping film changes into ductile stretching after being subjected to the tensile force. Vertical stretching will make the stretch film softer and the overall width will decrease. Such characteristics can make the stretch film of the stretch film manufacturer stronger to maintain and package the goods;
