HOUSTON, Dec, 16 -- ExxonMobil Chemical has announced the commercialization of two new higher density grades of Exceed metallocene-based linear-low-density polyethylene (mLLDPE). These new grades have densities of 0.927 and melt indices from 1.3 to 3.5. Grade names are Exceed 1327CA and Exceed 3527CB.
Potential applications include heavy-duty shipping sacks, stretch film, hygiene film, liners, and merchandise bags. These new grades offer an outstanding balance toughness for high-performance films and stiffness for potential downgauging.
ExxonMobil said its recently announced mVLDPE grades for flexible packaging applications along with these new higher density grades demonstrate its long-term, commitment to metallocene technology.
The increased densities of these new Exceed mLLDPE grades provide greater stiffness than lower density materials, without sacrificing the overall toughness end-users need, the company noted. The improved stiffness-toughness balance allows for significant cost reductions without compromising performance. Manufacturers of heavy-duty sacks and liners benefit from the greater stiffness which provides better creep resistance and the ability to carry heavy loads. Stretch film manufacturers can use these higher density products as the non-cling layer to offer better puncture resistance and load retention versus conventional materials.
