Which Heat Sealer? - Heat Sealer | Hand Sealer

A heat sealer (or bag sealer) is a device used to seal various types of packaging and thermoplastic materials. There are different designs for different sealing requirements. When choosing a heat sealer, the first and most obvious question you should ask is, what are you trying to seal? Heat sealers are used to seal a wide range of materials for many different applications and projects. Heat seal bags are hermetically sealed, ensuring that your products are protected against tampering, airtight, waterproof, and hygienically enclosed. Often, you have a pre-cut bag or pouch that contains identical monolayers. In other words, just 'single-layer' materials, like simple plastic bags. Other packaging, such as foil bags or pouches, may have multiple layers that need to be sealed simultaneously.
