A cigarette rolling paper and method for manufacture is disclosed which describes a cigarette rolling paper containing an inner paper that has plant oleoresins, essential oils, and or rosins applied to the inner paper through a screen printing process, which in turn is bound to an outer paper. The oleoresins are applied using both an evaporative and silk screen-printing technique. The final rolling paper contains an precise, pre-measured amount of oleoresin and is intended for flavoring and enhancing hand rolled cigarettes, and promoting a slow and even burn.

Plastic packaging materials and processes that facilitate recycling of PET (polyethylene terephthalate) containers such as PET bottles and crystallizable clear PET-g (glycol-modified polyethylene terephthalate) labels such as heat shrinking sleeve labels. 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.

The present invention relates to a method of providing a packaged food product comprising printing a substrate with an aqueous printing ink composition, drying said ink composition to provide a printed substrate and packaging a food stuff with said printed substrate, wherein the method excludes printing or applying any layers over the dried ink composition, wherein the ink composition comprises water and polyester resin. The present invention also relates to use of an aqueous printing ink for printing on a substrate, wherein the printed substrate has less than 50 ppb migratable species when heated to temperatures in excess of 150? C., wherein the aqueous ink composition comprises water and polyester resin.
