Standard Practices for Making Laboratory Heat Seals for Determination of Heat Sealability of Flexible Barrier Materials as Measured by Seal Strength

Importancia y uso:

4.1 These practices facilitate the determination of laboratory heat sealability of flexible barrier materials. While it is necessary to have a heat seal layer that provides adequate seal strength for the application, other material properties, such as the overall construction and thickness, will impact the sealing properties of the material. These practices allow the impact of changes in material properties on heat sealability to be measured.

4.2 Due to differences between a laboratory sealer and manufacturing equipment (for example, scale, size of sealing area, and processing speed), there may be a significant difference between the capability and output of a laboratory heat sealer and that of manufacturing equipment. Hence, care must be taken when applying a heat seal curve study as outlined in these practices to manufacturing equipment. The heat seal curve and the corresponding seal strength data are intended to provide a starting point for determination of sealing conditions for full scale manufacturing equipment.
