Description

Technical Field

[0001] The utility model relates to the technical field of plastic stretch resistance detection devices, in particular to a degradable plastic bag stretch resistance detection device. Background Art

[0002] Degradable plastic bags refer to plastic bags that can be decomposed into harmless substances through natural degradation or microbial action under specific environmental conditions. Their performance and uses are similar to those of traditional plastic bags. They can meet people's daily needs and also achieve the effect of protecting the environment.

[0003] The traditional way to test the tensile strength of plastic bags is to evaluate their tensile strength by manually stretching the bag, fix the two ends of the bag, and then gradually apply tension by hand until the bag breaks. By observing the performance of the bag during the stretching process, such as deformation and breakage, its tensile strength can be preliminarily evaluated, or different amounts of weights can be used to apply pressure to the plastic bag, and the deformation of the plastic bag can be observed with the naked eye. When the weight reaches a certain amount, the plastic bag will break, or the plastic bag can be directly stretched horizontally manually until it is broken, but these methods are not enough to accurately detect the performance of the plastic bag, as well as the tensile strength of the plastic bag in different directions, and compare the data with those used in actual environments. A Chinese patent discloses a "plastic packaging bag tensile strength detection device", whose application number is "CN202222492320.6". The device avoids the use of additional weights for detection, which is an inaccurate and unsafe detection method, but can only perform conventional, one-direction detection on the plastic bag, and does not reflect the simulation in the actual use environment and the detection comparison in different directions. In order to further achieve this effect, a device is designed to solve this problem. Utility Model Content
