The firms, which employs 13 staff members, now has plans to take this figure past the £3m mark by 2017.
The new European deal will see MacLellan Rubber provide premium grade material to companies producing seals and gaskets for the food and drink sector.
The manufacturing agreement is expected to open up £500,000 of new opportunities with converters, original equipment manufacturers, fillers and importers.
Simon Winfield, director of MacLellan Rubber, said: “This is where we come into our own.
Thanks to the new agreement we have signed, all our Food Grade rubber sheet material is now manufactured within Europe, sourced directly from European compounders and is 100% batch tested with full raw material traceability and compliant to all relevant quality accreditation.
“We have also invested heavily in new stringent controls and pre-production equipment cleaning and all our staff are fully trained and boast significant technical expertise.”
Andrew Onions, a fellow director at the firm, continued: “If things go as planned, we will definitely have to create more jobs, with the possibility of adding further apprentices to the three we already employ.”
