KeyForm L0400
Formerly
Lupolen 2420D

Natural
Non-additivated low-density polyethylene with high melt strength for blown-film extrusion and good bubble stability.
Description
KeyForm L0400 is a non-additivated low-density polyethylene supplied in pellet form. Its high melt strength contributes to good bubble stability during blown-film extrusion. The technical data sheet lists good processability, good tear strength and good toughness. The grade is listed for agriculture film, bags and pouches, heavy-duty packaging, liner film, shrink film and stretch hood. Contact Genesis Polymers to discuss KeyForm L0400 for your application.
Processing Techniques
Blown film is the listed processing method. Specific operating conditions and end-use suitability must be determined for the application.
