Stretch wrapping can resemble more of an art than a science in the absence of rigid wrap standards and consistent testing. In order to prevent damage and maintain the continuity of the pallet during transportation, the products must be carefully placed, and the pallet must be wrapped to contain them. Even now, hand wrapping is still a popular but inefficient way of wrapping pallets. Depending on the volume, it may take more time, effort, and money than utilizing a machine wrapping approach. It is also a labor-intensive task with a higher risk of injury than any sort of machine wrapping. Wrapping by hand is generally a laborious and uneven job.
The four most popular pallet wrapping alternatives are shown below with explanations of how they operate, what to anticipate, and the particular benefits of employing each option. It is crucial to first explore the distinction between automated and semi-automatic machines in order to comprehend the common types of stretch wrappers. A pallet is automatically fed into the wrap zone at the beginning of the line by an automatic stretch wrapper, where it is wrapped in accordance with the parameters on the control system. A new pallet is automatically delivered into the wrap zone as the completed pallet is moved to the end of the line.
Contrarily, a semi-automatic stretch wrapper needs a person to load and unload the machine, start the wrap cycle, and make the necessary corrections to guarantee the load is wrapped properly.
Turntable Wrapping
In its most basic configuration, the pallet is put on a rotating turntable while a film delivery system applies stretch film to the load. The typical setup for the film distribution system is to begin at the bottom of the load, wrap to the top, and then wrap back down to the bottom. The most common kind of stretch wrappers are turntable wrappers, which can be set up to function well with a range of applications.
Straddle Wrapper
Straddle stretch wrappers work differently from turntable machines in that the load is stationary while the film supply mechanism spins around it. These wrappers can wrap from low to large volumes and can manage unsteady, light, and heavy loads.
Ringer or Orbital Wrapper
A pallet is wrapped over and under by a ringer or orbital wrapper, usually as the load is conveyed through the machine on a conveyor. For flattened or awkward loads like doors, pipes, carpet rolls, coffins, etc., they are typically used.
Ring Straddle Wrapper
Up to 200 loads can be wrapped at high speed using these machines. They are frequently observed in the beverage, paper towel, and tissue sectors. Ring strappers are extremely specialized machines that make up a very small percentage of the stretch wrappers now in use. There are four standard and typical ways to stretch a wrap. Each of these varieties of stretch wrappers has add-ons and optional features that increase their versatility and capabilities. You can select the ideal wrapper machine for your requirements.
