Perception is reality. Despite the fact that the safety of PVC has been demonstrated in a large number of scientific studies, on-going concerns about PVC by certain segments of consumers have prompted OEMs in a number of markets to specify alternate materials. While types of PVC compounds still account for the largest share of the North American compounding market, at a minimum many processors want to have a non-PVC substitute material approved and ready to run should a customer require it. Increasingly these processors are relying on compounders to supply them with modified or new grades of TPEs specifically commercialized for flexible PVC-replacement applications. 

Polymers has recently introduced film-grade formulations based on its styrenic block copolymers (SBCs) to the North American market. The materials, which contain no plasticizers, are targeted for stretch-films used in food applications. The materials were first developed in response to regulations in Japan prohibiting the use of PVC in food wrap, now selling the product in Japan, as well in several European countries; and it has attracted pre-commercial interest of several North American companies. One of the key benefits of the material is that it can generally be processed on the same equipment as PVC. 

 With traditional SBC you usually have a high shear characteristic, so we’ve developed a low-shear product that will allow customers to use their regular equipment without additional capital investments

The SBC polymers are blended with polypropylene and the material is typically co-extruded with EVA in a three-layer structure. The film has clarity, elasticity and barrier properties similar to PVC.
