Product Description

Fully auto rotary arm stretch wrapper is used to efficiently and securely wrap pallets with stretch filim. This type of machine is commonly used in warehouses, distibution centers, and manutacturing faciities to streamline the palet wrapping process and ensure that products are properly protected during storage and transportation.In addition to increasing efficiency, automatic pallet stretch wrappers also help to reduce waste by using the exact amount of stretch filmneeded to wrap each pallet, This not only saves money on materials but also helps to minimize the environmental impact on packaging waste. lt can help to improve productivity, reduce costs, and ensure that products are properly protected during shipping and storage.
