Heat Sealing in ASTM F2029 Standard

ASTM F2029 standard refers to practice for making laboratory heat seals for determination of heat sealability of flexible barrier materials as measured by seal strength. According to ASTM F2029, a heat seal layer is critical to provide adequate seal strength. In addition, other properties of the material including the overall construction and thickness, have an effect on the sealing properties of the material.

Temperature, Time, and Pressure of Heat Sealing

ASTM F2029 standard dicta the preparation of heat seals in laboratory. What are the most effective parameters of heat sealing process? The answers are heat-sealing temperature, dwelling time, and heat-sealing pressure which are also the three aspects for determining heat sealability of flexible barrier materials.
