CCL Label Völkermarkt has announced the development of a new Super Stretch Sleeve, Triple S, which supports a sustainable bottle-to-bottle recycling process.
The material construction makes an optimal recycling process possible, and the technology competes well against shrink sleeves from an environmental and cost point of view.
The sleeve can be applied to individually-designed and shaped containers, due to the high elasticity of the Triple S film, together with stretchable inks, which have been developed for this application in particular.
A material stretch of up to 54% means the system is suitable for shaped bottles with variations in diameter of up to 35%, besides this, 50% less material is needed than for a comparable shrink sleeve.
The new material, which is suitable for squeezable bottles, is a printed high stretch polyethylene based sleeve for the decoration of contoured PET bottles.
It can be easily removed and enables bottle to bottle recycling and clean separation from PET flakes.
To assess the effect of the Triple S material on the quality of recycled PET, the Technical Committee of European PET Bottle Platform (EPBP) authorised an independent laboratory.
EPBP concluded that the sleeve will have positive impact on current European PET recycling.
Tests demonstrated positive impact on existing European PET recycling based on conditions that the density of the printed sleeve is below 0,96 g/cm³ and the inks do not bleed into the washing solution during the PET recycling process.
