One of Haremar’s key customers is privately held Sons Bakery, Brampton, Ontario, Canada, which has supplied hamburger buns to McDonald’s restaurants in Ontario since 1984. The buns are packed in a 6x5 pattern using clear, unprinted film from Haremar. Sons refers to the 30-count packs as “pillows.”
After overwrapping, one or two pillows are loaded into reusable plastic trays that are shipped directly to more than 300 McDonald’s restaurants.
With its newfound tri-extrusion upgrade, Haremar switched Sons in August from a ½-mil monolayer film that was a linear low-density polyethylene/LDPE blend to a superior three-layer ½-mil film, says Haremar’s Mark Lichtblau. The new film comprises three identically thick layers of a blend of LLDPE/LDPE using resins from Dow Chemical, according to Lichtblau. He says that all three layers are “LLDPE-rich.” Haremar was able to maintain film costs for Sons because the improved line efficiencies offset added resin costs.
