No. Tools for steel are vastly different from tools for polyester. While both steel and polyester can be closed using seals, the tools are different and are not interchangeable. Besides, there are an abundance of tool options with polyester that offer a productivity gain. You will want to explore the tooling options ideal for your application.
If you want to switch from steel to polyester, you’ll need to invest in the right tools. Making the switch will save your plant more in the long run.
With a rotary arm stretch wrapper the load to be wrapped remains stationary. The arm containing the stretch wrap rotates around the load. A turntable stretch wrapper is the opposite; the load to be wrapped rotates and the stretch wrap is applied as the table is turning. A rotary arm stretch wrapper is designed to handle any load that is heavy, tall, or unstable. The machine allows the load to stay stable on the floor during the wrapping process.
A turntable stretch wrapper is designed for pallet jack or forklift loads. Since the turntable must rotate, it is limited by the load weight. Other considerations between the two will be ceiling height, available floor space, and budget.
Joint strength is affected by many factors. The type of tools you use and how those tools are set up and used are of primary importance. For example, metal clips come in different sizes and configurations. Longer serrated seals are more efficient than shorter smooth seals. Additionally, with seals, there is a chance that the seals are not closed sufficiently as it is a manual process relying on the diligence of the operator. Friction or heat welded joints are less susceptible to these problems as long as the tool is set up properly for the strap. Once set up, the tool ensures a proper weld.
For that reason metal clips are often rated at a 50% seal efficiency while welds are rated at 75% or higher.
