sealinghot
Sealinghot is a term used in packaging technology to describe a heat-activated sealing process that produces a tight, hermetic seam on flexible substrates such as multilayer plastic films and laminates. The name derives from the combination of sealing and hot, reflecting the central role of heat in forming the bond.
Process and materials: Sealinghot relies on a heat-activated adhesive or heat-softenable film, applied to one or
Applications: It is widely used in food packaging, medical pouches, and consumer electronics packaging, especially for
History: The technique developed in the late 20th century as packaging demands shifted toward higher integrity
Variants and considerations: Variants include impulse sealing and hot-bar sealing, with differing bar configurations, temperatures, and
