heat-seals
Melts edges together
Heat-seals is the verb form of heat-seal, meaning to join materials—typically plastic or foil—by applying heat and pressure to fuse them together.
The technique creates airtight closures on packaging: The machine heat-seals each bag before shipping.
Heat-sealed packaging keeps food fresh and products tamper-evident.
