ORRVILLE, OHIO — Even as the company's Uncrustables business accounted for more than one half of the year-over-year decline in one segment and smaller losses in another, executives at J.M. Smucker Co. are bullish on the long-term profitability of the frozen sandwiches, which were introduced in 1998. Uncrustables enjoyed 25% volume and net sales growth in the retail sector during the second quarter ended Oct. 31, versus the same period in 2013.
