NanoXplore and Techmer PM have introduced GrapheneBlack xGnP Masterbatch for use in plastic film.
The graphene-based material recorded an improvement of more than 70% in mechanical strength, according to a press release from NanoXplore.

The release added that it could allow film thickness to be reduced by as much as 20% while retaining tensile, tear and puncture properties.
The companies added that the material could help raise the share of recycled content in film formulations without reducing performance, as packaging producers respond to more stringent sustainability rules and circular economy objectives.
NanoXplore president and CEO Rocco Marinaccio said: “The combination of NanoXplore’s new xGnP graphene technology and Techmer’s application development and compounding capabilities produced a genuine breakthrough for our joint customers — one that neither company could have achieved alone.”
The product was developed through a collaboration between NanoXplore and Techmer PM, combining NanoXplore’s xGnP graphene technology with Techmer PM’s work in film applications and compounding.
Techmer PM Techsperse dispersion technology helps distribute graphene through the material to support consistent and repeatable results.
The company added that, together with its manufacturing processes, this supports consistency between production lots at commercial volumes.
For product development, Techmer PM has in-house film production equipment, including a five-layer blown film line for small-scale sampling and process testing.
This setup allows customers to work on formulations, assess multilayer structures and move products towards market launch.
Techmer PM CEO Craig Foster commented: “Our partnership with NanoXplore helped us bring a high-value graphene-based solution to market that directly addresses some of our customers’ most pressing performance and sustainability challenges while also driving meaningful cost savings.
“It’s a strong example of our commitment to delivering practical, forward-looking solutions that enable our customers’ success.”
NanoXplore filed a provisional patent last month.
The companies plan to present the co-developed product line at the AMI Flexible Packaging Innovation and Recycling Conference in Milwaukee, US, scheduled for 24–25 June 2026.
Founded in 1981, Techmer PM is a materials design company focused on changing the properties of technical polymers.
NanoXplore produces graphene and has an annual capacity of 4,000 metric tonnes in Montreal, Canada.
