Tubular films produced from EGDA-6888 are recommended for high strength grocery sacks, shopping bags, produce bags and high quality thin films for multiwall sack liners and replacements for thin paper products. EGDA-6888 is also suitable for making non-pressure “gravity” pipes for drainage and sewage applications.
- Food Contact Usage
EGDA-6888 can be used for all food contact applications including holding food during cooking. It conforms to US FDA Regulation 21 CFR 177.1520 as well as EC Directive 90/128/EEC and its amendments to-date. Food contact suitability certificate is available upon request.

Technical Details & Test Data
- Typical Extrusion Conditions
EGDA-6888 can be extruded on conventional HDPE blown film equipment at 215C melt temperature. A flat or moderately increasing temperature profile is recommended for its extrusion.
A 4:1 blow-up ratio and high stalk bubble configuration are always recommended for products requiring high strength. Lower blow-up ratios (3:1) can be used for products that do not require high strength.
For best gage uniformity, a minimum extrusion rate of 0.14 kgs/hr/mm of die circumference is recommended. The best balance of extrudability and film strength is obtained with a 1.0 to 1.1 mm die gap.
