heat-sealing
Melting edges together
Heat-sealing is joining materials, typically plastics or coated papers, by applying heat and pressure to melt surfaces together.
The technique creates airtight bonds for packaging: heat-sealing food bags, heat-sealing blister packs.
A heat-sealed edge fuses rather than glues, making it tamper-evident and moisture-resistant.
