Beschreibung
Zusammenfassung:	The present invention relates to plastic packaging materials and processes that facilitate recycling of PET (polyethylene terephthalate) containers e. g PET bottles and crystallizable clear PET-g (glycol- 5 modified polyethylene terephthalate) labels such as heat shrinking sleeve labels. Disclosed herein is a clear primer coating for recyclable PET-g shrink-sleeve labels, curable upon exposure to UV light, which is excellent in adhesion, steam-resistance and overprint ability, and Which promotes the de-inking of subsequent coloured ink layers under relatively mild caustic wash conditions. Methods of utilizing such a primer coating within ﬂexographic printing processes are also 10 encompassed within the invention. Fig. 1
