Westlake Mxsite LC78105-C Polyethylene Film, Using Energx Technology Services (discontinued **)
Categories:	Polymer; Film; Thermoplastic; Polyethylene (PE); Low Density (LDPE); Low Density Polyethylene (LDPE), Molded
Material Notes:	Mxsite LC78105-C polyethylene is recommended for the skin layers of blown stretch film. It will provide a very aggressive cling force in both a stretched and unstretched condition. The excellent cling force comes without a substantial increase in film unwind force. It is designed for machine wrap and hand wrap applications where good processability, low gel content and substantial cling are needed. It can be used as cling layer in many "one-sided cling" films because it clings very well to many non-cling resins. Applications/Uses Cast film Films Stretch film Eastman Chemical Company sold its polyethylene business to Westlake Chemical Corporation in Dec. 2006. This grade no longer appears in the Westlake product line.
