The strength of recycled material stretch film is one of the important indicators for evaluating its performance. The following is a detailed analysis of the strength of recycled material stretch film:
1. Definition and importance of strength
The strength of stretch film usually refers to its tensile strength, that is, the maximum stress that the material can withstand during the stretching process. For recycled material stretch film, good tensile strength means that it can effectively wrap, fix and protect items to ensure that they will not break or slip during transportation, storage, etc.
2. Characteristics of the strength of recycled material stretch film
Raw material influence: The strength of recycled material stretch film is affected by the type, quality and recycling process of raw materials. Recycled materials from different sources have different physical and chemical properties, which will affect the tensile strength of recycled material stretch film.
Production process: During the production process, the process conditions such as melting, extrusion, and cooling of recycled materials will also affect the strength of the stretch film. Appropriate process conditions can ensure a good bond between material molecules and improve the strength of the stretch film.
Test data: According to the data provided by reference article 1, the tensile strength of regenerated cellulose film increases with the increase of cellulose solution concentration, but when the concentration is too high, the tensile strength decreases. This shows that when preparing Recycled material Stretch film, it is necessary to control the appropriate solution concentration to obtain higher tensile strength.
3. Strength test and standard
The strength of the stretch film is usually tested by a tensile testing machine and evaluated according to relevant standards.
The strength of Recycled material Stretch film is one of the important indicators for its performance evaluation. Recycled material Stretch film with good tensile strength can be prepared by controlling the type, quality and recycling process of raw materials and optimizing the production process conditions. In practical applications, it is necessary to comply with relevant standards and requirements to ensure that its performance meets the requirements. With the improvement of environmental awareness and the advancement of technology, the application of Recycled material Stretch film in logistics, packaging and other fields will become more and more extensive.
