Joining plastic films by controlled application of heat and pressure to the area to be sealed.
A process by which heat is introduced to 2 substrates to seal them together. Heat sealing is a generic term and is part of many packaging processes, but it mainly refers to the closure of polybags. ( Find out more)
The process of joining two or more thermoplastic films or sheets by heating areas in contact with each other to the temperature at which fusion occurs, usually aided by pressure.
A method of joining plastic films by simultaneously applying heat and pressure to areas in contact.
A method of bonding two or more surfaces by fusing thermoplastic or thermosetting coatings of films under controlled conditions of temperature, pressure and time (dwell).
Fusing together two or more thermoplastic films, such as low density polyethylene, through the application of heat and pressure.
A method of joining two plastic surfaces by applying heat and pressure to the area of contact. Heat may be conductive or inductive.
A process in which heat is used to fasten together two substrates.
a method of sealing plastic containers by heating two adjoining layers or portions of the container until they melt together thereby forming a good seal.
Sealing a package by applying heat to cause the film to melt together. This process must be tightly controlled to prevent "false sealing" such as cold seals and to prevent "zippering" from hot seals.
The process of bonding two (2) or more surfaces together by heating the adherent surfaces so that the heat seal coating or film is melted, thereby affecting an adhesion between those surfaces. Pressure is often added along with heat.
