Description

Technical Field

[0001] This utility model relates to the technical field of tensile strength testing equipment, specifically a tensile strength testing equipment for packaging film processing. Background Technology

[0002] Packaging film mainly refers to films used for packaging goods. It typically includes polyethylene film, biaxially oriented polyester (BOPET), BOPP film, and CPP film, etc. It is mainly used for packaging food, medicine, and textiles. Packaging film needs to undergo repeated quality testing during production. Among these tests, the tensile strength of the packaging film is a particularly important factor, as it affects the quality of the packaging film in its later use.

[0003] Currently available tensile strength testing equipment for packaging film processing has poor protective performance, which can easily cause the packaging film to loosen when rotated. This will affect the test data of the packaging film and also affect the subsequent storage and use of the packaging film.
