Omet and Ritrama have announced a partnership at Labelexpo Americas 2018 which will make new converting equipment available for Ritrama’s Core Linerless Solution.
Core Linerless Solution (CLS) makes use of a siliconized 12 micron PET liner which is laminated on the reverse side of a 30 micron face material.
The converter simply prints the roll in the normal way, and because there is no die-cutting the press can run considerably faster. Omet’s converting machine delaminates the multi-purpose liner, and laminates it to the top of the label using an activatable adhesive. This leaves the adhesive side of the face material exposed and encapsulates the print leaving the silicone surface on the top face. The 42 micron roll goes through a micro-perforation station and slitter inspection rewinder.
The Core Linerless Solution requires a specialist application machine, which is manufactured by Italian company Ilti. The applicator separates the micro-perf and attaches the label to the container at the same speed as a PSA applicator. There is no liner waste, and three times as many labels per roll compared to a PSA roll, which means fewer label applicator roll changes.
Although only square/rectangular labels are possible, the labels can be die-cut with rounded corners. Omet points out that the label design can still ‘simulate’ a die-cut label as it is on a clear material.
The key target market is primary product decoration, where Ritrama estimates 80 percent of face labels are square shaped and more than 90 percent of the back labels are square or rectangular.
At its press conference at Labelexpo Americas, Omet also explained in more depth the reasons behind its alliance with Durst, which sees Omet incorporating the Tau 330 RSC print engine with XFlex X6 flexo press modules.
