In the Creep Test, a whole package is inflated to a constant pressure, which is then held for a specified time, resulting in a pass/fail result (see Figure 5). Early users of the method for peelable seals used the test as an analogy for the pressure difference on the seals seen in the ETOCO2 transmission rate test by weighing method: Water vapor transmission rate test by inverted cup method: Non-destructive test for packaging seal performance: Multi-station packaging pressure test: Tensile test of packaging materials with ultra-long elongation: Heat-seal strength test for cap films of medical bottles, yogurt cups and jelly cups
Close the drain of 2 and 3 sealing chamber and then feed oil to the line between 2 and 3 seals and fill the oil to the top of the plug. Check the level of oil is not dropping; Similarly close the drain plug between 4 and 5 seals chamber and feed oil. Check for oil leakage from seal 5 in the forward area1.2 These test methods are restricted to instrumented hot tack testing, requiring a testing machine that automatically heatseals a specimen and immediately determines strength of the hot seal at a precisely measured time after conclusion of the sealing cycle. An additional prerequisite is that the operator shall have no influence on the test after the sealing sequence has begun.
To achieve vacuum level sealing, a maximum surface roughness of 16 μin. (0.41μm) has been recommended.3 Therefore, sealing surfaces on the test fixtures had to have surface finishes of 16 μin. or better. The sealing surfaces on both sides of the interface also had to be precisely aligned so that the amount of compression on the seal test6.
