INTELLIGENT BEST APPLICATION USES FOR STRETCH WRAP For most load securement processes, stretch wrap is wound from a coil of film around the perimeter of the shipping unit. The film is pre- stretched and shrinks when applied, providing a snug multi-layer shell around the load perimeter. It is especially effective on lighter products where its elastic- ity is not a limitation. It can im prove stability to non-uniform or unstable products that are hard to contain with strap. It also provides good dust protec- tion and with addition of a cover, can provide rain protection. Most stretch film is made from linear low-densi- ty polyethylene (LLDPE), the fourth most recycled plastic. It is less widely recycled than PET, but there is a market for recycled film when quantities are collected. It is generally run through a film grinder in prepa ration for recycling. STRETCH FILM IS PARTICULARLY IMPORTANT FOR PRODUCT PROTECTION – STRAPPING PROVIDES THE LOAD WITH THE NECESSARY STABILITY FOR TRANSPORT. HOW DO STRAP AND STRETCH WRAP COMPARE? Both products can be applied with a range of technologies from hand applications to fully automatic systems, with production rates from a few loads to over 150 per hour. Stretch film can be wrapped around the pallet perimeter, providing some resistance to the product sliding off the pallet during handling and transport. However, vertical straps that pass through the pallet void or under the load are the best option for tying loads to pallets and restraining heavier, settling, and, expanding loads during storage and shipment. Film is somewhat gentler on the package. Strap can cut into packaging after tensioning and vulnerable products may require top frames to prevent strap from indenting or cutting into packaging. While it is an issue for the customer rather than the producer, strap is easier to remove from the load than film and takes up less space after removal. Strapping and stretch film have different charac- teristics and bring different advantages as packag- ing solutions. Sometimes they are com petitors, but sometimes a combination provides the opti- mum solution. Film does a good job on lighter loads, containing unstable stacks and non-uniform loads, and provides a dust and moisture barrier. Strap works better with heavier loads, tying loads 28
