Mondi rolls out NextLiner – the world’s first sustainable PCK release liner

27 August 2020: Austria based Mondi, global leader in packaging and paper, has introduced the world’s first sustainable polycoated kraft (PCK) paper release liner. The NextLiner uses a recycled base paper with a coating made from renewable resources. Using recycled fibres and renewable materials can have a positive impact on the environmental footprint of NextLiner, used in graphic arts, tapes and other industrial applications.

Polycoated kraft paper has several advantages over alternative constructions, as it doesn’t tear easily and offers comparable moisture resistance properties. It has good layflatness, even when wet, and typically comes in an overall higher grammage (e.g., 90-gramm) compared to the standard, thinner options often used for labels.

Usage of release liners continues to grow. Polyolefin coated paper consumption is around 9 billion m2 per year with a market share of 16% of the total release liner market – which makes environmentally responsible alternatives in the sector all the more important. The launch of NextLiner is a first important step in the development of sustainable liners with more to come. Mondi is continually conducting research and development into more sustainable release liner alternatives (for PCK as well as paper- and film-based release liners) and recycling-related technologies

According to the company, NextLiner is currently available in a 90-pound PCK grade (90# Liner), a standard graphic arts grade. Additional grades are available by adjusting the polycoating and paper weight. NextLiner is available in a plain or structured version (as AirXLiner).
