Specialty paper bags are widely used in various fields such as chemical industry, food, and building materials. Their tear strength is directly related to usage safety and product reputation — tearing easily when loading heavy objects can lead to material leakage, damage during transportation can cause economic losses, and may even trigger potential safety hazards. Therefore, the tear strength testing of specialty paper bags is far stricter than that of ordinary paper products. The method of manual estimation by hand feel and repeated tearing not only has great errors and cannot accurately judge whether the paper bags meet the usage standards, but also cannot form traceable and referable test data. A professional tensile testing machine just solves this pain point, making the tear strength testing of specialty paper bags more scientific and convincing.

To meet the testing needs of specialty paper bags, the core advantage of the tensile testing machine lies in quantifiable force values and more scientific testing, while the operation remains convenient and worry-free. No professional testing qualification is required. You only need to cut the specialty paper bag samples according to industry standards, fix them stably on the upper and lower chucks of the tensile testing machine, and start the equipment after confirming that they are clamped tightly. The machine will apply tension at a uniform and stable rhythm, collect the force value changes in real time during the tearing process until the paper bag samples are completely torn, and automatically lock and record key data such as the maximum tear force value and average tear force value, forming accurate and verifiable test results. This quantitative testing method completely gets rid of the subjectivity and randomness of manual testing. Each set of data is true and reliable, which can not only accurately judge whether the specialty paper bags meet the industry standards, but also provide a scientific basis for the optimization of paper bag production processes, greatly saving the trouble of repeated manual testing and inaccurate data.

With quantifiable force values and scientific testing, the tensile testing machine guards the quality bottom line of specialty paper bags, avoids usage risks, and escorts the safe application of specialty paper bags.
