Elasticity refers to the property of a substance that can return to its original state after being deformed under the action of an external force. For PE stretch film, its elasticity is mainly manifested in the following aspects:
1.Stretchability: PE stretch film has good stretchability and can adapt to different shapes of items within a certain range. When an item is wrapped in stretch film, the PE stretch film can be stretched to a suitable length, so that the item can be fully and evenly covered and maintain a certain degree of tightness.
2.Resilience: PE winding film has good resilience, and when the external force is removed, it can quickly return to its original state without leaving obvious traces or wrinkles. This resilience ensures that items remain neat and aesthetically pleasing during transportation, storage, and sale.
3.Flexibility: PE stretch film has strong flexibility and can maintain good performance in different environments. For example, in a low temperature environment, the PE film will not become brittle and can still maintain good flexibility; In a high temperature environment, the PE stretch film will not become soft, and it can maintain a good use effect.
4.Puncture resistance: PE stretch film has strong puncture resistance, which can effectively protect items from damage caused by external factors during transportation and storage. Even when subjected to a certain external impact, the PE stretch film can effectively protect the article from damage.
To sum up, PE stretch film has good elasticity and can adapt to different use environments and requirements. During packaging, transportation and storage, PE stretch film can effectively protect items from damage and maintain a neat and beautiful appearance. Therefore, PE stretch film has been widely used in the packaging industry.
