Product Description
TOPAS 8007F-400 is a robust film extrusion grade designed for blending with polyethylene (PE). It is a moderate clarity amorphous resin with high stiffness, moisture barrier, chemical resistance, thermoformability and purity for food and general purpose applications. It is used in blends in both cast and blown processes, and in monolayer and multilayer products. Leading film applications include twist wrap, forming webs, protective packaging, shrink films and labels, and easy tear packaging. Industrial uses include formed PE and PP sheet products. For property enhancement at elevated temperatures, higher glass transition temperature (Tg) grades of TOPAS are recommended.

Selected Applications

• Forming films (header bags, etc.)

• Protective packaging

• Shrink films and labels

• Twist films

• Decorative sheet

• Food packaging

• Food contact

Leading Attributes

• Clarity, forming, barrier, purity, halogen-free

• Stiffness for downgauging, improved forming

• High shrink, low stress, gloss, toughness

• Outstanding deadfold, clean cutting

• Stiffness, chemical resistance, forming, even draw

• Not manufactured with BPA, phthalates, or halogens

• Broad regulatory compliance

Related Grades for Packaging and Film Extrusion

• TOPAS 8007F-04 - ultimate clarity extrusion grade

• TOPAS 8007F-600 - robust clarity extrusion grade especially for PE blends
