Product Description
Exceed™ XP 7021ML is an extreme Performance linear low density polyethylene 1- hexene copolymer that is especially designed to have high melt strength and superior mechanical and optical properties. The combination of high toughness (impact and puncture), melt stability, superior flex crack resistance and good sealing performance makes this grade a versatile blown film resin. TnPP is not intentionally added to Exceed™ XP 7021ML.
