Plexar Tie-Layer Adhesives

Plexar resins enable polyolefins to bond to a variety of polar and non-polar materials including EVOH, nylon, PET, PS, PU, PVdC, metal, and paper.

Plexar tie-layer resins are anhydride-modified polyolefins that bond dissimilar polymers together in multilayer structures. The functional groups within Plexar resins enable the resins to bond to a variety of polar materials including ethylene vinyl alcohol (EVOH), nylon, polyethylene terephthalate (PET), polystyrene (PS), epoxy, polyurethane (PU), polyvinylidene chloride (PVdC), metal, paper, and other substrates while still providing excellent adhesion to polyethylene. As a result, multilayer structures can be produced with unique properties that combine key properties of various resins, such as the low oxygen permeability of EVOH, the stiffness and low moisture vapor transmission rate (MVTR) of high density polyethylene (HDPE) or sealability of ethylene vinyl acetate (EVA).

Plexar tie layer adhesives are manufactured by LyondellBasell and marketed in the U.S. and Canada by MSI Technology. Technical information for Plexar is available by clicking here.
