The addition strengthens Antalis’ portfolio for printers and converters producing high-quality packaging, carton and graphical POS and display applications.

Antalis has added Sun Strong, a premium GC2 boxboard manufactured by Burgo, to its large format range.
Sun Strong is a coated GC2 (FBB) cardboard produced from three layers of bleached virgin fibres, incorporating a CTMP (Chemi-ThermoMechanical Pulp) middle layer. This structure provides a good combination of stiffness and flexibility, ensuring smooth performance in folding, finishing and die-cutting processes.
The board features a smooth, satin-finish surface, with a double coated top side and an uncoated reverse, delivering consistent results for offset and flexo printing. It is also suitable for a range of additional surface treatments, supporting premium packaging requirements.
Available in sheet and reel formats, Sun Strong is supplied in weights ranging from 275 to 325 g/m², offering flexibility across a wide range of packaging and graphic applications.
Sun Strong is 100% recyclable, manufactured using ECF pulp, certified to FSC® and PEFC standards, and achieves a rating of 4-stars in Antalis’ Green Star System™, supporting customers’ sustainability and compliance objectives.
“Sun Strong is a high-quality GC2 board that performs reliably across printing and converting,” said Paul Neale, Product Manager at Antalis UK. “By adding Sun Strong to our portfolio, we are giving printers and converters access to a board that combines strong visual quality, efficient runnability and recognised sustainability credentials, all backed by Antalis’ local availability and service.”
