Technical Information
DOWTM LDPE 352E
Low Density Polyethylene Resin
Overview
DOW LDPE 352E Low Density Polyethylene Resin is a high clarity resin designed for clarity over wrap applications. This resin does contain erucamide slip and antiblock additives. It can be readily extruded using conventional blown film techniques utilising melt temperatures between 160 and 175 ?C.
This resin when properly fabricated exhibits: ? Excellent processability and draw drown. ? Outstanding toughness and impact properties. ? Superior optical properties. ? Excellent tensile and tear strength.
Note: DOW LDPE 352E Low Density Polyethylene Resin should comply with FDA regulation 177.1520 and with most European food contact regulations when used unmodified and processed according to good manufacturing practices for food contact applications. Please, contact your nearest Dow office for food contact compliance statements. The purchaser remains responsible for determining whether the use complies with all relevant regulations.
Applications: ? Light-produce bags. ? Soft goods packaging. ? Textile packaging. ? Good optical general purpose bags. ? Hygiene films. ? Food packaging films.
