Heat Seal Tester

For many products, the impact of packaging on shelf life and product safety is critical to success. Packaging technical teams will carefully specify packaging material characteristics in terms of functional and barrier properties, for example, the oxygen transmission rate for an oxygen-sensitive product. Despite this, the highest risk to pack integrity and shelf life can be failures in the pack heat seals or closures.

Heat seal parameters are easily measured, Heat Sealability = Temperature + Pressure + Time. Yet maintaining optimum heat sealing conditions in production and recognising the true cause of poor sealing remains a challenge.

Saicheng Heat seal tester (also called Laboratory heat sealer) is to determine the suitable sealing parameters (Sealing Temperature, Dwell Time and Pressure) for materials.

Saicheng heat seal tester is widely used in the plastic industry and designed for accurate and repeatable measurement heat sealability of flexible packaging. Produces seals up to 330mm long and 10mm wide. Independent temperature control of the upper and lower jaws gives multiple combinations of test conditions.

Heat Seal Test Standard

Complies with ASTM F2029 - Standard Practices for Making Laboratory Heat Seals for Determination of Heat Sealability of Flexible Barrier Materials as Measured by Seal Strength

Seal Strength Test Method

According to the heat sealing conditions specified under the product item, the samples are heat-sealed on the heat seal tester, then peeling the seal apart with a seal strength tester to measure either ultimate seal strength (after cooling, method ASTM F88).
