2. Hand warmer - Wikipedia

   en.wikipedia.org/wiki/Hand_warmer

   The release of heat is triggered by flexing a small metal disk in the hand warmer, which generates nucleation centers that initiate crystallisation. Heat is required to dissolve the salt in its own water of crystallisation and it is this heat that is released when crystallisation is initiated. [9] The latent heat of fusion is about 264–289 kJ ...

Heat sealer used to prepare plastic bag of lettuce for shelf life testing Continuous band heat sealer. A heat sealer is a machine used to seal products, packaging, and other thermoplastic materials using heat. This can be with uniform ...

4. Induction sealing - Wikipedia

   en.wikipedia.org/wiki/Induction_sealing

   Induction sealing is the process of bonding thermoplastic materials by induction heating. This involves controlled heating an electrically conducting object (usually aluminum foil) by electromagnetic induction, through heat generated in the object by eddy currents. Induction sealing is used in many types of manufacturing.

   A hot glue gun loaded with a glue stick. Hot-melt adhesive (HMA), also known as hot glue, is a form of thermoplastic adhesive that is commonly sold as solid cylindrical sticks of various diameters designed to be applied using a hot glue gun.

6. Strapping - Wikipedia

   en.wikipedia.org/wiki/Strapping

   Manual sealers for plastic strap always use a seal and a compression (serrated seals) or crimp joint (smooth-faced seals). Automatic hand tools are used for higher-volume applications. Automatic tools can be powered by an electric battery, or by compressed air. Automatic hand tools for plastic strap use a friction weld.
