The Midlands-based firm has recently become the exclusive UK stockist and distributor for Accurate Freeze, which it has stocked since October.
It said this service will eliminate the requirement for any additional processes and, with orders being cut to their ideal specifications, customers will not have to make do with a "best fit" option, thereby reducing both their waste and environmental impact.
Accurate Freeze, which has an off-white back surface, high brightness and smoothness and a gloss finish, is suitable for applications including frozen/chilled foods, cosmetics and pharmaceuticals, confectionery and chocolate.
The product, which is available in a wide range of reel widths and is supported by a full range of sheet stock, is both Forest Stewardship Council (FSC) and Programme for the Endorsement of Forest Certification (PEFC) certified.
Warren managing director Kieran Ferguson said: “We are delighted to introduce this fantastic new product to our range – both in reels and sheets.
“With exceptional performance combined with a local, reliable mill source and our renowned service levels, Accurate Freeze will, in our opinion, prove to be one of the most popular folding boxboards within its sector in the UK.
“Mayr-Melnhof Eerbeek and Warren have enjoyed a successful partnership for many years and I’m certain that with Accurate Freeze now on board, we’ll see this flourish further.”
ISO 14001-certified company Warren has 39 staff and sales in excess of 25,000 tonnes per annum with a turnover of £22m.
It has recently opened a 3,902sqm converting facility in West Bromwich and also has five units in Glenfield, Leicestershire covering a total area of 10,684sqm. Its customers include paper merchants, commercial and general printers and carton convertors throughout the UK and Europe.
