Polymer films containing platelet particles

Thin polymer films containing small sized platelet type filler. The polymer has a melt index of from 0.01 to 10 grams per 10 minutes at 190 DEG C. to 250 DEG C. as measured on ASTM Test No. D-1238 at a load of 1000 to 2160 grams. The preferred polymer is polycaprolactam or high density polyethylene....

Beschreibung
Zusammenfassung:	Thin polymer films containing small sized platelet type filler. The polymer has a melt index of from 0.01 to 10 grams per 10 minutes at 190 DEG C. to 250 DEG C. as measured on ASTM Test No. D-1238 at a load of 1000 to 2160 grams. The preferred polymer is polycaprolactam or high density polyethylene. There is from 10 to 50 percent of a platelet filler having an average equivalent diameter of from 1 to 8 micrometers, a maximum equivalent diameter of about 25 micrometers, and an average thickness of less than 0.5 micrometers. The preferred filler is talc. The film is from 10 to 100 micrometers thick and can be a single ply or a laminate.
