Mann Packing Co. Inc., Salinas, Calif., and Hefty, Lake Forest, Ill., are creating joint coupons for the back-to-school season.

The coupons, of which there will be 1 million between mid-August and mid-September, give consumers $1 off two boxes of Hefty OneZip bags and will be attached to Mann Packing products — including Sugar Snap Peas, Simply Singles and Vegetable Medley.

“As a mom, I understand the struggle to provide healthy lunches and snacks for kids,” Lorri Koster, vice president of marketing, said in a news release. “We’re excited to partner with Hefty so healthy lunches are easier to make.”

Mann Packing tries to do a promotion every year around the time school starts up, even if it’s as late as Labor Day weekend, Elena Hernandez, marketing coordinator for Mann, said. The company tries to bring fresh produce into children’s lunches and add value wherever they can, she said. This is the first time they have partnered with Hefty for this promotion.

“Overall it’s a good fit,” Hernandez said. “We’re bringing a well-known name into produce.”
