MONTREAL, June 15, 2026 (GLOBE NEWSWIRE) -- NanoXplore Inc. (“NanoXplore” or the “Company”) (TSX: GRA and OTCQX: NNXPF) and Techmer PM today announced the commercial launch of a GrapheneBlack xGnP™ Masterbatch, a new graphene-enhanced solution designed for high performance plastic film applications. The product has demonstrated more than 70% improvement in mechanical strength and may enable thickness reduction of up to 20% while fully maintaining tensile, tear, and puncture performance.

This graphene-enhanced solution also has the potential to significantly increase the amount of recycled content that can be incorporated into film formulations without sacrificing performance, a critical advancement for packaging manufacturers navigating tightening sustainability mandates and circular economy targets.

The jointly developed product is the result of a powerful collaboration combining NanoXplore’s proprietary high-surface-area xGnP™ graphene technology with Techmer PM’s deep films application expertise, world-class compounding capabilities, and broad customer network.

A key enabler of this performance is Techmer PM’s advanced dispersion technology, Techsperse™, which ensures optimal graphene distribution for consistent and repeatable improvements. This capability, combined with Techmer’s rigorous manufacturing standards, delivers exceptional lot-to-lot consistency customers can rely on at commercial scale.

To further support customer development, Techmer PM also offers in-house film production capabilities, including a 5-layer blown film line that supports small-scale sampling and real-world process validation. This allows customers to collaborate directly with Techmer PM and NanoXplore to rapidly iterate formulations, evaluate performance in multilayer structures, and accelerate the overall design and commercialization process.

NanoXplore filed a provisional patent in May 2026, and the companies will officially unveil the new co-developed product line at the AMI Flexible Packaging Innovation and Recycling Conference in Milwaukee on June 24–25, 2026.
