It's a great day to be Irish in spirit and like packaging. Who doesn’t appreciate a sampling of seasonal packaging? Today is St. Patrick’s Day and that means a decidedly green scheme. March 17 th is a day celebrated as St. Patrick’s Day by residents of Canada, Ireland, Montserrat, United Kingdom, and United States, according to timeanddate.com. And it’s celebrated by all those who, for at least one day, declare themselves Irish at heart. Lacking the usual public festivities associated with the day of Irish-inspired merriment, we’ve assembled a virtual packaging party with a line-up of like-minded packaging designs drawn from press releases and Twitter.
