Heat sealing is the process of sealing one thermoplastic to another similar thermoplastic using heat and pressure. The direct contact method of heat sealing utilises a constantly heated sealing bar to apply heat to a specific contact area or path to seal or weld the thermoplastics together. Heat sealing is used for many applications, including heat seal connectors, thermally activated adhesives, film media, plastic ports or foil sealing.
Focus on Heat Sealing
This can be with uniform thermoplastic monolayers or with materials having several layers, at least one being thermoplastic.
Heat sealing can join two similar materials together or can join dissimilar materials, one of which has a thermoplastic layer.
Automatic heat-sealing machines allow the packing and sealing of products in preformed trays (in PS, PP, APET, CPET, aluminium and coupled cardboard, glass jar etc) by heat sealing.
Pre-formed heat-sealed trays are ideal for packaging a wide variety of food, non-food and medical products.
Depending on the type of packaging, the needs and the production volumes required, we can supply the most suitable standard solution or we can study and customise a bespoke solution.
