What Is a Sealer?
Sealer refers to both devices and materials used for sealing bags or containers.
Utilized to preserve the freshness of food and pharmaceuticals, sealers come in various types such as heat sealers, vacuum sealers, and crimp sealers.
Heat sealers employ heated plates or wires to melt and seal the edges of packages. Vacuum sealers extract air, creating a vacuum that prolongs the freshness and shelf life of contents. Crimp sealers use pressure from presses or rollers to join two surfaces securely.
