EN 868-5 Packaging Materials Heat Self-Sealable Pouches Plastic Film
This method is used to investigate the strength of the heat seal joints used for heat and self-sealable pouches, and reels for use as packaging of medical devices that are sterilized. The EN 868-5 test method is suitable for use with a range of materials manufactured from paper and plastic film used in packaging.
In principle, the free ends of the test specimen is supported between two clamping jaws and is pulled apart until failure at a constant rate of displacement. This test is to determine the peel characteristics of paper/plastic laminate products, as well as the strength of the heat seal joint for pouches and reel material.
We use screw action grips, pneumatic action grips with rubber coated jaw faces for clamping of the material, which are fitted to a tensile testing machine - normally a single-column or dual-column table-top design. Using materials testing software, such as Bluehill®, you are able to input specimen details, set the desired test control, automatically calculate the desired results and statistics, and produce a test report all in accordance with the standard.
We suggest reviewing EN868-5 to fully understand the test fixture and results requirements.

Screw side-action grips provide a very simple and efficient method for holding test specimens in a wide range of applications. The dual - acting design of 2710-100 series grips means that jaw faces can be adjusted to accommodate different specimen thicknesses. This ensures that the line of tensile force remains concentric with the grip body. They can be equipped with a selection of interchangeable grip jaw faces in various sizes and choice of surfaces including smooth ground, rubber-coated and serrated. Line contact and special coated faces are also available.The unique ‘snap-on’ jaw face attachment makes changing faces extremely quick and simple.
