cPET Shrink Sleeve Label Film

Crystallizable PET (cPET) shrink sleeve label film is used to make washable shrink sleeves, which can be 100%  fully recyclable with the bottle flakes, will help to increase the yield and quality of rPET. 

In order to avoid the need for material separation and thus improve the yield and quality of rPET, crystallizable PET (cPET) shrink sleeve label film has been developed as a technically comparable alternative to PETG shrink label film. In contrast to PETG, crystallizable PET is compatible with the PET bottle recycling stream and does not adversely impact the rPET-quality, enabling the recycling of both materials, the bottle PET and the cPET shrink sleeve simultaneously.

For the printing ink,  washable ink is reuqired to be used in all relevant printing processes for shrink sleeves. These UV-curing and solvent-based inks and primers ensure a smooth deinking of cPET-based shrink sleeves during the usual washing conditions in the PET bottle recycling process and at the same time are non-bleeding to avoid any contamination of the washing water which might affect the rPET quality.
