Sai Paks calls this innovation for Chitale milk bottle sleeves a new generation sleeve. The product uses shrinkable gold cold foil specifically developed for the pure gold effect on shrink sleeves.
In February 2023, Chitale Bandhu Mithaiwale was about to launch a one-litre PET bottle for milk and was looking for a different kind of shrink sleeve. The company wanted the logo to be printed in gold.
Sai Paks started by printing the artwork with surface-printed matte-effect and surface-printing gold foil. It did not work as the gold foil faded. Then Sai Paks received a special foil from Kurz. Still, the gold looked slightly faded. Then, a layer of varnish was applied, and finally, the intended result was achieved.
For the product, Sai Paks also developed the configuration of its new UV flexo press, which should have a hot air dual rewind after the ninth colour and then one more UV for extra curing for speciality coating.
Printed on 40-micron cast PVC, with CMYK plus white plus shrinkable gold foiling plus matte UV on the surface, 10,000 shrink sleeves were produced.
