Standard Practices for Making Laboratory Heat Seals for Determination of Heat Sealability of Flexible Barrier Materials as Measured by Seal Strength
These practices cover laboratory preparation of heat seals. These practices also cover the treatment and evaluation of heat seal strength data for the purpose of determining heat sealability of flexible barrier materials. It does not cover the required validation procedures for the production equipment.
Testing of seal strength or other properties of the heat seals formed by these practices is not included in this standard. Refer to Test Method F88 for testing heat seal strength. These practices do not apply to hot tack testing, which is covered in Test Methods F1921.
The practices of this standard are restricted to preparing heat seals using a sealer employing hot-bar or impulse sealing methods, or both.
Heat Seal Tester HST-H3
HST-H3 Heat Seal Tester is designed to determine the optimal heat seal parameters, including dwell time, sealing pressure, and sealing temperature, for plastic films, flexible composite films, plastic-coated paper, and other heat-sealable materials.
We hope this helps and as always, we aim to ensure we can help and be proactive.
