Bag Inserters (Bag-in-Box)

Bag inserters line the inside of a case with a plastic bag liner and cuffs the bag over the top of the open case, typically for bag-in-box applications. Most oftenly, this is done by companies who are shipping loose product in bulk to be used as an ingredient or further packaged by their immediate customers. This process allows clients to ship in bulk, in smaller than tote quantity; often around 25# cases. Some common products where the bag inserter is applied include bulk hot fill cheese, 25# of sweetened dried cranberries, frozen fruit and vegetables, and nuts, granola and other snack foods.

Kelley Supply offers bag inserters that have a smaller footprint and lower height than other units on the market. Our unit saves customer 7% in film circumference versus competitive units. We use mechanical grippers instead of vacuum to grab the film for higher reliability. Kelley Supply provides completely automatic bag inserter machinery with servos; not manual cranks. Our machines are made out of a stainless steel frame construction; and most parts where feasible. We can also implement our machines with a filler, case erector, decuffer/folder/sealer for complete Bag-in-Box lines.
