Bag Lifting Fatigue Testing Machine

This Bag Lifting Fatigue Testing Machine is suitable for up and down vibration fatigue test of plastic handbag, garbage vest bag, kraft paper bag, woven bag and other bags bearing a certain weight. After many fatigue tests, the strength of the bag can be determined. The bag lifting fatigue testing machine adopts the automatic test mode, placing the sample on the fixture, setting the lifting times and load weight, and automatically completing the experiment process and printing the results. This fatigue testing machine is widely used in quality inspection institutions and handbag manufacturers.

FAQ

(1) What is the Bag Lifting Fatigue Testing Machine used for?

The machine is designed to evaluate the fatigue strength of bags under repeated lifting conditions. It simulates real handling situations by applying cyclic lifting loads to loaded bags, helping determine whether handles, seams, and bag structures can withstand repeated use without failure.

(2) What types of bags can be tested with this machine?

This tester is suitable for plastic shopping bags, garbage bags, kraft paper bags, woven bags, reusable handbags, and other packaging bags with load-bearing handles. It is widely used in packaging production, quality inspection, and material research applications.

(3) Which standards does this bag fatigue tester comply with?

The equipment is designed according to bag testing requirements including GB 21661, BB/T 0013, and BB/T 003. These standards define performance evaluation requirements for plastic bags, paper shopping bags, and packaging products.

(4) How does the bag lifting fatigue test work?

The sample is filled with a specified weight material, installed on the lifting fixture, and subjected to repeated vertical lifting cycles. After completing the preset number of cycles, users inspect whether cracks, tearing, handle damage, or structural failure occurs.

(5) Why is fatigue testing important for bag manufacturers?

Repeated lifting can weaken handles, seams, and material structures even when a bag passes static load testing. Fatigue testing helps manufacturers improve product reliability, optimize materials and designs, reduce customer complaints, and ensure compliance with packaging quality requirements.
