Sabic collaboration with The Japan Steel Works (JSW) validates the use of Sabic linear low-density polyethylene (LLDPE) BX202, a resin developed for processing on tenter frame extrusion equipment for biaxially oriented PE (TF-BOPE) packaging film. The value chain collaboration endorses the use of Sabic ‘s TF-BOPE material on JSW film lines, extends the machine supplier’s footprint into the BOPE film market for flexible packaging, and underscores SABIC’s role as a forerunner in this market segment.

Says Sami Al-Osaimi, executive VP petrochemicals at Sabic, “There is a growing market trend and demand for mono-material solutions to facilitate the end-of-life recycling of used packaging products while at the same time supporting the efforts of brand owners and packaging manufacturers to down-gauge their applications and meet ambitious reduction targets. The partnership with JSW has confirmed our strong commitment to accelerate the implementation of advanced material and equipment solutions for flexible packaging by working with global value chain partners who share our mindset to reduce, reuse and recycle as we contribute to a circular plastics economy.”

The extensive trials found that this TF-BOPE grade is currently considered the best-in-class to run on existing tenter frame film lines for BOPE as well as on slightly modified equipment for biaxially oriented polypropylene (BOPP).

Toshiyuki Ninomiya, vice plant manager, Hiroshima Plant for JSW explains, “After testing SABIC’s LLDPE BX202 material in our Bi-Axial Film Stretching pilot line, we were positively surprised by the performance of it. Its excellent processability combined with good mechanical properties makes this material a great addition to our recommendable materials portfolio for our customers and strengthens our position in the BOPE market. By collaborating with SABIC for use of their overall high-performance TF-BOPE resin on our advanced film extrusion lines, we are actively promoting the broader implementation of more efficient and sustainable, circular ‘mono-materialized’ film solutions designed for recycling.”

Sabic reports that LLDPE BX202 material combines outstanding processability with good mechanical and optical properties, including clear transparency and twice the impact strength, puncture resistance, tensile strength and stiffness compared to conventional blown PE film of equal thickness. This means it offers significant potential for further downgauging and corresponding reductions in weight, material consumption, and carbon emissions. At potential packaging material reductions of up to 50% vs. incumbent blown PE film, this also translates into potentially higher line speeds with shorter cooling times, maximizing the productivity of applications.

Also, the mono-PE material enhances the recyclability of final flexible packaging applications at the end of their lifespan without compromising the integrity of the packaged products such as frozen food, fruit, and vegetable packaging applications. Sabic’s TF-BOPE polymer is also available in certified circular as well as certified renewable grades from the Trucircle portfolio.
