PROCEDURE FOR HEAT SEALING OF TEMPERATURE SENSITIVE ORGANIC POLYMERIC MATERIALS AND HEAT SEALING MEASURES CONTAINING A COPOLYAMIDE FOR USE IN PERFORMANCE

摘要

The invention relates to copolyamides containing caprolactam, lauriclactam, hexamethylene diamine adipate and hexamethylene diamine salt of an aliphatic dicarboxylic acid with a carbon chain of 9, 10, 12 or 13 carbon atoms. The copolyamides are useful as heat-sealing agents.
