Fold-Pak
Fold-Pak is a division of Rock-Tenn with two locations: Hazleton, PA and Fresno, CA . Fold-Pak manufactures Bio-Paks, SmartServ, and Fold-Pak - which is commonly used for Chinese and Thai food. The design comes in a variety of sizes and can be stored flat and easily set up when it is ready to be used. When set up, it is very durable and light weight. Its special kind of cardboard can stand up to large amounts of grease or other liquid toppings. Its use is good for carry-out duties because it has a hook and a slot on its top flaps and it can be flipped upside down without spilling its contents.
