With an estimated $60 billion of waste from unsalable products each year resulting from ineffective stretch wrapping in just the consumer products goods, food, and beverage industries, improving the effectiveness of stretch wrapping is an important step in any shipping operation.
Make sure your loads arrive at your customers' locations in “as made” condition. Don’t chance it. Here are three things you can do regardless of the model or age of your stretch wrapper to improve your probability of success.
Step 1: What is Containment Force?
At its most basic, Containment Force is the hugging pressure that holds your load together. Containment Force is the result of the number of revolutions of the stretch film multiplied by the wrap force (tightness). It's the key specification in reducing damage and ensuring safe to ship loads. You'll need to do testing and checking to discover your ideal Containment Force. However, when measuring Containment Force, you should check three places on a wrapped load to make sure we have the right amount of force throughout the load.
Sustainability has been a hot topic in the CPG packaging industry since the 90s when mass retailers started to respond to consumer pressure to develop programs around source reduction and recycled content.
Manufacturers which supply the retailers have pushed machine and materials suppliers to provide a range of solutions that enable them to comply with incremental source reduction targets. Suppliers have delivered, and manufacturers have consistently met or exceeded the "score card" targets set by major retailers and industry organizations.
Trade associations have also joined the discussion. PMMI's recent Earth Day infographic, for instance, illustrates the emphasis on the topic.
Use the Force: Containment Force Is the Key to Safe Pallet Loads
Here’s how to attain – and maintain – the right containment force for your loads.
A 120-case pallet of maple syrup arrives at the dock of a big box retailer. The trailer’s rear doors open and out tumbles the load. Boxes cascade off the pallet, leaking crushed glass and syrup. The receiving supervisor slams the doors and sends the driver off. A sticky – and costly – situation.
No matter what you’re shipping, loads must be wrapped right, and that means achieving the right amount of containment force.
Most stretch wrappers come with manuals on how to operate and trouble-shoot the machines. But they barely begin to cover what you need to know to create a safe-to-ship load.
In last week's blog, we point out that even though stretch wrapping has become the standard way to unitize a load for shipment, hardly anyone does it well, which creates a lot of bad loads.
Stretch wrapping has come a long way since its invention just over forty years ago. Today, an amazing variety of methods and machines are used to stretch wrap over two-and-a-half billion pallets each year in the United States alone.
Think of these photos as evidence in a crime scene. Innocent loads have been struck down in the process of trying to get to their destinations in the condition that they were originally made.
The scope of the consumer electronics industry is huge and accounts for $200 billion in sales every year, according to the Consumer Electronics Association.
However, some of the industry’s profits disappear.
