MASTERBATCH | MATERIALS
thin-gauge voided MDO PE films that combine low density and high opacity. This creates a PE-based alternative to conventional PP-based substrates that often require biaxial orientation. “Using Void’s VO+ technology enables us to achieve the high opacity, ease of processing, and recycle-ready performance we are targeting for these films,” said Brent Greiner, vice-president of technology at Charter Next Generation. “This helps our customers reduce their use of virgin materials and process their packaging in existing PE film recycling streams.” The masterbatch is added to PE resin to create nano and micro-scale voids, reducing density and creating high levels of opacity via light scattering through the voided structure. The latest product is compliant with direct food contact standards in North America and Europe and has passed key recycling standards. Void also offers its VO+ PE 1300 series voiding agents for recyclable opaque films. The resulting voided polyethylene (PE) film structures are compatible with existing PE recycling streams and meet the needs for a range of packaging applica- tions such as laminates, wicketed bags, labels and flow wraps. It is being used to develop voided MDO HDPE films that combined low density and high opacity.
Medical range Gabriel-Chemie has introduced a new master- batch range for the medical industry, which is designed to meet the strict requirements of ISO 10993. The new line features polyethylene (PE)- and
polypropylene (PP)-based polymer carrier masterbatches, and was developed to help
streamline bio-compatibility concerns. The company says that the medical master-
batches will help to reduce product development times due to being a ready-made product range. “This is reflected in the careful selection of raw
materials that meet ISO 10993 standards,” said Diego Karpeles, corporate business development and innovation manager at Gabriel-Chemie. “Our product range also includes specialised laser-mark- ing masterbatches.” The medical masterbatches adhere to ISO 13485 certification, ensuring compliance with strict quality standards. The production process involves meticulous procedures, including isolated mixing, extrusion, granulation, filling, and storing. The range is not tested on animals. The company has also expanded operations at two European plants – in Austria and Hungary.

Left: EcoCortec will start making bioplastic masterbatches with its corrosion protection additive in Croatia
Green compounding EcoCortec has opened a new compounding facility in Croatia to make bioplastic masterbatches containing its VpCI corrosion protection additive. VpCI masterbatch is used to produce patented,
environmentally responsible films for corrosion protection. The VpCI embedded in the film vaporises and diffuses through an enclosed package, adsorbing onto metal surfaces inside. A thin layer then protects the metal against corrosion. EcoCortec can now produce a variety of
concentrated masterbatch products and integrate VpCI technology into biodegradable packaging. “By completing the entire production process in-house, we are now less dependent on outside sources,” said Dijana Zrinski, general manager at EcoCortec. “By overseeing operations from VpCI masterbatch compounding all the way to extrusion, converting, and printing, we can achieve better quality control.”
