PX 004-V by Polytechs is fully saturated ethylene-propylene copolymer (55%) based cling masterbatch in LLDPE carrier resin. PX 004/V is designed to make LLDPE stretch film by either blown film or cast film process. Its cling properties give low noise and low static when unwinding film rolls and will not cause any problem of roll telescoping after production. It produces a cling film that is pleasant to touch in comparison with films made with other cling agents. It is compatible with most polyolefins, but not EVA. PE resins used in any stretch-cling film composition must not contain any slip or antiblock additives. It is used in PA to improve surface finish of molded parts (especially mineral filled grades), to assist processing of complicated molded parts and to increase impact strength (especially falling weight impact). It is used for applications such as cling additive for stretch film, carrier for pigments and fillers, process aid and impact modifier for polyamide. PX 004-V improves the production output in compounding and extrusion. Used concentrations are between 8 and 10 % for cast films and for blown films, addition level is higher at approximately 15 %. 10% LDPE should be added on blown film lines, as this acts as a synergist for cling. Usually an addition level of 1-2% is used for polyamides. It is approved for contact with food as outlined by the FDA and the EEC legislation.
