Packaging: Semi-automatic stretch wrapper uses unique film

DB Schenker, the transportation and logistics arm of Deutsche Bahn and world’s second-largest freight forwarding provider, employs 95,000 people across 130 countries in 2,000 locations. Its largest and most active U.S. location, Chicago, recently installed a semi-automated system using an engineered wrap to boost productivity and product protection.

DB Schenker’s Chicago branch handles product from around the world, from retail and raw material to medical supplies. Most products arriving from the Far East arrive in loose bundles that are made into unique loads—50 to 150 per day—stretch-wrapped and shipped on a skid for delivery.

“The need for wrapping has always existed,” says Joe LaPorta, special projects/procurement supervisor for DB Schenker. “We simply discovered a more efficient and cost-effective way of doing it.”

Two new semi-automated stretch wrappers can be used by hand or machine. The puncture-resistant film is as much as 30% stronger than other pre-stretch films of equal weight. Rolls are 50% lighter than conventional 70-gauge film rolls and are easier to maneuver.

LaPorta says the film’s unique hemmed edges ensure the film won’t break or tear if the roll is dropped or falls. In fact, the supplier guarantees all customers will use the entire roll without breaking or snagging. Another feature eliminates the need to pull and stretch the film while wrapping, since the film will continue to contract around the load.

A turntable pallet wrapper can wrap 20 loads per hour with a 90-inch wrapping height and 65-inch diameter. It also features an adjustable wrap pattern and 4,400-pound capacity.

“Before we bought film and machines from separate vendors,” LaPorta says. “The program uses really solid products and we have had no breakdowns on the machine or issues with the film.”
