heat seal
Melt plastic shut
Heat seal refers to joining materials—usually plastic or coated paper—by applying heat and pressure to melt surfaces together.
The technique creates airtight closures on packaging: The bag was heat sealed to keep the contents fresh.
As a verb, to heat seal is to create such a bond.
Heat sealing is standard in food packaging, medical supplies, and industrial applications where airtight or tamper-evident seals matter.
