Description

Technical Field

[0001] The present invention relates to the technical field of new material testing equipment, in particular to a new material polymer composite bag tensile testing device. Background Art

[0002] Composite packaging bags can precisely meet the packaging needs of various products based on their specific characteristics, significantly extending their shelf life. During the production process, composite bag materials must be selected with specific packaging properties, including but not limited to water and oxygen barriers, light protection, oil resistance, chemical resistance, puncture resistance, anti-static, corrosion resistance, and electromagnetic radiation protection. These properties enable the production of a wide variety of composite packaging bags that fully meet product packaging needs. Due to the wide range of applications for composite packaging bags, component materials can be flexibly added or removed during the production process based on specific customer needs. This flexibility ensures that each product receives the packaging solution that best suits its characteristics. After adding or removing component materials, to ensure that the composite packaging bags meet quality standards, rigorous pre-production testing of the new components is required. Tension testing is a common monitoring method. This method clamps the two sides of the plastic bag and stretches one end, then uses a tension sensor to accurately measure the change in tension. This step is crucial as it helps us accurately assess the strength and stability of the composite packaging bag, ensuring that the final product meets the customer's stringent requirements.

[0003] As for the currently existing tensile testing device for new material polymer composite bags, it is difficult for the device to automatically flatten the surface of the composite bag during the process of fixing the composite bag; since wrinkles are prone to appear on the surface of the composite bag, wrinkles can easily interfere with the tensile testing performance of the device, resulting in inaccurate test results; in addition, after completing the tensile test and tearing the composite bag, the device is not easy to automatically crush and recycle, which increases the cost of manual processing and reduces the overall utilization efficiency and environmental performance of the device.
