New cast film grade stretches limits in cost and energy efficiency

Improved stiffness, the potential to improve line speeds considerably, and excellent mechanical properties are the claimed attributes of a new grade of LLDPE for cast film applications from Sabic (Riyadh, Saudi Arabia).

Diapers are but one application for Sabic's latest LLDPE cast film grade.

Grade Sabic LLDPE 430BE is also said to feature outstanding quality consistency and its combination of properties opens up new opportunities for quantifiable energy and material savings - which supports converters to improve their cost efficiency as well as their sustainability performance, according to the supplier. "This new cast film resin is a very pure grade with a controlled low gel level, making for a reliable and consistent product ensuring smooth processing. Moreover it optimizes energy and material usage," comments Krzysztof Rozensal, technical marketing engineer for LLDPE at Sabic.

Due to its increased density, Sabic LLDPE 430BE is suited for application in differential cling stretch film applications as "low cling" outerlayer. The high quality consistency and specific design of Sabic LLDPE 430BE enables converters to improve line speeds without compromising on a stable and consistent manufacturing process. Usage of the grade as a side-encapsulator combined with Sabic LLDPE 318BE and Sabic LLDPE 6318BE makes cast film line speeds up to 1000 m/min feasible according to Sabic. "This clearly proves the value of this grade in an industry that is continuously aiming for higher speeds" explains Rozensal.

Besides a wide area of stretch film applications, Sabic LLDPE 430BE can also be used for hygienic cast film applications and thermoforming sheets. Sabic LLDPE 430BE enables converters to increase the stiffness of the film which results in further downgaging possibilities. "Our new cast film product supports our customers achieving a more efficient and more environmentally friendly production process" says Rozensal.‑[email protected]
