This fixture was designed to test overall strength of a reinforced handle on a plastic bag.  The fixture simulates a hand holding the sample and the test measures the breaking point to evaluate pass/fail conditions. The handle can also easily be replaced with different size/shape hooks for various pull strength or peel strength tests.

Description

The handle strength test fixture is designed to simulate a hand holding a bag.  Measuring the overall strength of a reinforced handle on a plastic bag when filled.

For this application a plastic film bags with a die punched handle, the goal is to ensure the bag is strong enough to hold from the handle with at least 100lbs in the bag. 

Using MAP4 Materials Testing Software with the Vantage Universal Tester the test would run until there was a failure of the handle or another part of the bag.  MAP4 Analysis included Force Traps at 20lb, 40lb, 80lb in order to determine the elongation/stretch of certain forces.  The overall force and stretch required for handle failure are also reported.  Handle Strength is reported lbs./in but units of measure can be modified,  

  • Lower Grip with 6in wide jaws to clamp the lower portion of the bag
  • Upper hook fixture to loop through the handle as a hand would. This is attached to the load cell.

 

The handle can also easily be replaced with different size/shape hooks for various pull strength or peel strength tests.
