PW cling masterbatch is dedicated to many applications related to polyolefin stretch films, like silage stretch films, and other polymer films, with support of Polytechs team to integrate it properly.

The use of PW cling masterbatch inside high-quality stretch films is an essential component as it brings clingability to the film structure. Depending on the market that is targeted, Film producers shall rely on specific cling effects from Polyisobutylen technology, for instance, Combination of High Peel cling Strength and High Lap cling Strength for high-quality bale silage.

For pallet stretch films, Polymer film producers seek for a bonding agent like PW cling masterbatch to be added to stretch film to increase the stickiness quality of the film. This is a key target requirement to allow the layers of stretch film applied to bond to the previous layers effectively creating a single wall of stretch film. For Food stretch films, PW cling masterbatch is used in vast range of applications comprising packaging, labeling and lamination. Many other applications are still to be developed, such as use of PW cling masterbatch in recycling or anticorrosive films.

PW is a cling masterbatch for polyolefin stretch films that has several effects and side benefits. It is designed to produce stretch film based on LLDPE, LDPE or other polyolefin, targeting the applications of pallet wrap, silage wrap and food wrap films. It can be used in blown or cast film processes and is working with monolayer and multilayer films structures. PW is supplied as dried and non-sticky pellets and is food contact compliant.

For over 30 years, Polytechs has fine-tuned its process and recipes to ensure delivering the best possible offer in term of cling masterbatch, based in Polyisobutylen technology. Today, 3 grades are proposed to the market, PW 60, PW 70, PW S, covering the main market needs sought by the industrials.  One of the biggest value of PW come from its high quality consistency, world widely renowned by industrial peers. Beyond the offer, Polytechs dedicated time in supporting its customers, easing the integration of PW inside the film recipe and processing mode. Its teams investigated a lot on parameters & effects influencing migration, quality and performances.

Since the 90s, Polytechs has been able to demonstrate the gains of using PW cling masterbatch, from a pure performance stand-point, and in the end from cost/performance balance stand point as well, adapting each of its recommendation to the customer needs.
