EDL’s Double Tight Wrappers Use LDPE Film

EDL Double Tight Wrap shrink-wrapping machines employ two perpendicular bands of LDPE film to tightly unitize and totally enclose multipacks of packaged pet foods. The two opposing wraps are then fused during heat shrinking to ensure that the individual packages are integrated into a stable unit that eliminates shifting of product. This makes the packages easier to integrate into pallet loads and simpler to offload and move by retail customers. Since the process does not fuse the wrapping film to the primary packaging, packs are easily opened and bagged product shelved at the retailer.

EDL Packaging designed these systems for the bundling of gable-topped, bagged and pouched pet food products, as well as large bags of cat litter. These are products that can shift within their primary packaging, making them difficult to move and palletize.  Clamps stabilize bags prior to wrapping and the finished tight wraps are sealed with teflon-coated constant-heat jaws. The systems are also used for various other food products that present similar challenges, such as beans, and food service consumables such as nested fiber trays and cup holders. Maximum wrapping throughput is up to 22.5 bundles per minute, depending on the individual bag size, bag material and bundle pattern, and the company is currently working on increasing the system’s throughput speed beyond 22.5 bundles per minute.

Double film coverage better protects the abuse-prone corners and edges of bundles. It also allows the use of cost-effective lighter-gauge film. The design of the EDL Double Tight Wrap system results in a 15-40 percent reduction in film consumption vs. tradition total enclosure shrink packaging systems. EDL’s high-efficiency heat tunnel, in turn, often leads to a 25-50 percent reduction in heat tunnel energy consumption.

EDL offers multiple layout options for its Double Tight Wrap systems to accommodate the unique production line needs of specific customers. Systems can be laid out, for example, in “U” or “Z” formats, or in other configurations. The systems, like all EDL machines, are designed for production flexibility, and to allow for future production line upgrades. The systems are commonly constructed with an easy-to-clean design to allow frequent cleaning and meet regulatory requirements.
