THERMAL IMPULSE BONDING OF THERMALLY SENSITIVE LAMINATE BARRIER MATERIALS.

摘要

Thermal impulse heat welding, or "bar sealing", is used to bond thermally sensitive laminate barrier materials such that they will pass AAMI level 4 testing (ASTM 1670 and 1671 -b). In bar sealing, overlapping layers of thermally sensitive laminate barrier materials are melted and fused together to create a substantially solid bond at and/or adjacent the surface. No substantially un-melted areas remain within the fused bond area on the surface.
