Mitsui Chemicals America, Inc. MIPELON™ Masterbatch

High-speed converting processes require rolled film to unwind easily and with minimal force. Blocking is the failure of the film to easily separate from itself and is most often seen in film with a large surface area and a smooth surface. To alleviate this problem, film producers create a micro-rough surface by adding finely milled inorganic slip agents like silica in low percentages into the polymer resin. The challenge, however, is these inorganic additives are by their nature incompatible with the polymer matrix in the film, which risks non-uniform surface irregularities and the particles being ejected from the film surface during rigorous unwinding and converting operations. MIPELON™ Masterbatch offers film producers and converters a new concept. MIPELON™ is a fine particle ultra-high molecular weight polyethylene and is more compatible than inorganic additives with either polyethylene or polypropylene resins in a film structure. The benefits of MIPELON™ are now available in an easy-to-handle masterbatch. Polyolefin films made with MIPELON™ Masterbatch can provide more uniform surface irregularities without particles falling off the surface, enabling more efficient converting operations.
