First 'No-Label Look' Wet Glue Film
Date: 11 September 2006
LabelExpo Americas (Chicago 11-14 September) sees the introduction of an exciting new film which brings the coveted “no label look” to traditionally applied cut and stack wet glue labels.Rayophane™, from Innovia Films, is a regenerated cellulose label facestock which will easily run on equipment set-up for paper labels and has been developed specifically for the labeling of glass and plastic bottles.
It eliminates the need for major capital expenditure typically required to install new pressure sensitive labeling equipment to apply clear plastic labels.
Rayophane™ labels can be removed using traditional industrial caustic washing equipment to allow bottles to be used in a returnable stream. The material has been qualified by Versuchs und Lehranstalt für Brauerei (VLB) for this use. Cellulose film will sink in water and washed-off labels show minimal curl allowing effective label waste collection.
The water permeability performance of Rayophane™ also plays a role in allowing caustic wash water to penetrate through the label and attack the adhesive. This applies to both wet glue and pressure sensitive applied labels.
Rayophane™, made from renewable wood pulp, has a low barrier to water vapor, and using special coatings, Innovia Films is able to fine-tune this natural characteristic to produce a film with the optimum permeability to allow fast drying of wet glue adhesives.
The wood pulp used in the manufacture of Rayophane™ is sourced exclusively from plantations operating sustainable forestry principles.
