- Basic Function
Definition and elaboration of winding membrane
Winding film is a kind of plastic film with special properties, which has good flexibility and ductility. It can protect, fix and package articles by winding and wrapping, and is widely used in many fields.
Basic function analysis
Its main function is to stabilize articles, prevent displacement and scattering during transportation or storage, effectively prevent dust and moisture, maintain the cleanliness and integrity of articles, and provide reliable protection for articles.
Function realization principle
By virtue of its own material characteristics, it produces a retraction force after stretching to wrap the article tightly, and its viscosity makes it adhere to the surface of the article, thus firmly fixing the article, forming a layer of protective barrier, and realizing various protective functions.

- Recommendations for matching load weight with film thickness
Load weight evaluation method
It is very important to accurately evaluate the load weight, which should be determined by scientific calculation or empirical estimation, taking into account the number, density and shape of the goods, so as to provide a basis for matching the appropriate thickness of the winding film.
Relationship between film thickness and load
The weight of different loads should be matched with the winding film of corresponding thickness. Generally speaking, thicker film is needed for heavier loads to provide sufficient support, while thinner film can be used for lighter loads. Reasonable matching can ensure packaging effect and cost control.
Practical case reference suggestion
Reference to actual cases is helpful to understand the matching of film thickness and load, such as the common load range and corresponding film thickness selection in specific industries, which can provide reference for similar application scenarios to ensure the best performance of winding film in packaging.
