The 3-station MAGMA and the 1-station NITRO test systems perform five types of tests:
Both test systems follow the test methods in ASTM F1921, ASTM F2029 and ASTM F88, and offer capabilities even beyond those standards.
With their many modes of operation the MAGMA and NITRO test instruments are designed to deliver maximum flexibility and versatility.
The strength of a seal at a very short time (typically in the 250ms to 500ms range) after the seal is formed is known as its hot tack strength. The MAGMA and NITRO test systems perform the hot tack measurement by first sealing the film sample at the user’s specified seal jaw temperature, jaw pressure and dwell time. Immediately after the seal jaws open, the test system performs a tensile test. During the tensile test, force data is recorded from which the hot tack strength is determined at the time intervals of interest.
A heat seal test determines the strength of the packaging film’s heat seal after stabilizing. In this mode MAGMA and NITRO operate similarly as in the hot tack test mode, but instead of immediately doing a tensile test, the systems automatically cool the seal for a programmable length of time using a selectable amount of air flow. Once cooled, the seal is peeled apart while tensile data is recorded for creating the strength profile.
Combining hot tack and heat seal tests saves substantial time when curves for both are needed. In the combined mode, at each temperature step the Pilot software prompts the operator to load specimens for either the hot tack test or heat seal test. After both tests are run, Pilot automatically increments to the next temperature where both test modes are run again. This saves valuable time as compared to waiting for temperatures to increment and stabilize for all temperature steps in separate heat seal and hot tack tests.
This mode is heat seal only, where the operator inserts the test specimens into the system as normal. The system forms the seal under the programmed conditions of temperature, pressure and dwell, and then stops. The seal is not peeled apart as is done in a complete test. Rather, the operator removes the sealed film for age-conditioning and for later testing in the post-aged mode.
When used in this mode, the MAGMA and NITRO test systems act as tensile testers to peel apart pre-aged heat seal samples to measure their strength. Samples that have been sealed and aged the required time are simply inserted into the system for peel testing.
