Choosing the right semi-automatic stretch wrapper for the right setting can be tricky, you must consider the loads being wrapped. While there are several different models to choose from, there are two basic styles of stretch wrappers to consider: a turntable or a straddle. The deciding factor is the construction and makeup of your pallet loads.
2 Types of Semi-Automatic Stretch Wrappers to Consider
Turntable Stretch Wrapper
With turntable stretch wrapper, the load is placed directly on a turntable that spins while the film delivery system moves up and down a mast dispensing the stretch film. A turntable typically rotates between 12 – 15 revolutions per minute, so a pallet load has to be stable enough to rotate without falling apart. If the load is lightweight or unstable, there are solutions. Machines can rotate slower to ease the stress on the load or you could add a Modular Electric Top Platen to stabilize the load during the wrap cycle.
Straddle Stretch Wrapper
With a straddle stretch wrapper, the load is placed on the floor in the middle of a wrap zone. The load remains still while a wrap arm moves around the pallet. The film delivery system moves up and down the wrap arm for complete film coverage. This is useful for very light or unstable loads that would fall apart if the pallet were to rotate on ta turntable. It’s also better for very heavy loads. Generally, the maximum weight capacity of a turntable stretch wrapper is about 5,000 pounds. Once you get beyond that, it is highly recommended that you use a straddle stretch wrapper.
Turntable stretch wrappers can handle the majority of stretch wrapping applications. Our semi-automatic stretch wrapper customers overwhelmingly purchase a turntable stretch wrapper. In fact, nine out of ten stretch wrappers sold are the turntable style.
3 Factors For Your Semi-Automatic Stretch Wrapper
Another consideration is floor space. A turntable wrapper is free standing. It can be moved if the need arises, however, frequent relocation is not recommended. Turntable wrappers fit nicely between dock doors, which is a popular location for semi-automatic stretch wrappers. A straddle wrapper is more permanent. Because the wrap arm can rotate at relatively high speeds it is required that the machines be anchored to the floor.
Straddle stretch wrappers tend to take up more floor space. There needs to be a safety clearance for the wrap arm to move around the pallet. These wrappers also have large legs at the base to help stabilize the machine as the weight shifts during the wrap cycle.
When ceiling height is an issue, the turntable stretch wrapper can be a better solution. Turntable stretch wrappers are typically shorter than a straddle wrapper with equal wrap height capacities.
Semi-Automatic Stretch Wrapper Budget
Budget is the final consideration. Turntable stretch wrappers typically range somewhere around $5,000 to $17,000, while straddle wrappers are more expensive starting at $17,500 and up.
