Wrapping by hand, with a semi-automatic stretch wrapper or with a fully automatic stretch wrapper. All three variants are possible. We explain the options for you:

Often used for very low capacities or very erratic loads. The disadvantage is very variable wrapping patterns, not everything from the film is used. Heavy work and low capacity.
A semi-automatic stretch wrapper is used when the capacity is too high to do everything by hand. A machine is often used from 5 pallets / hour. A machine always wraps in the same pattern. This gives a better packaging. The pre-stretching system ensures the correct dispensing of the film. With a semi-automatic pallet wrapper you are able to wrap up to 20-25 pallets/hour, also depending on the speed of the operator.
A fully automatic pallet wrapper is used when there are few operating personnel present. In addition, the capacities are often too high for a semi-automatic pallet wrapper. Fully automatic wrapping is applied from 10 pallets/hour.
The fully automatic pallet wrapper has several wrapping programs at its disposal. In case of a continuous flow of pallets, a programme can be provided per load. The process of this pallet wrapper is explained by means of an example:

Ever since the creation of stretch wrapping, various types of applications have been developed for unitizing pallet loads. One of these methods includes hand wrapping which involves a person walking around the pallet, securing the load with a hand-held stretch film roller. Although some people might find this method useful today, it’s not always the most productive.
Depending on the size and structure of the pallet that you are wrapping, there is a large amount of bending and twisting involved in making sure that the entire pallet is wrapped thoroughly. Even with orderly and square pallets, hand wrapping requires that an employee walk around in circles which causes dizziness and may lead to a higher risk of harm for employees. Thus, hand wrapping could generate inefficiencies in the supply chain process as work injuries cause downtime, high insurance costs, and workers compensation. Sometimes you may even need to hire a replacement worker which could result in more time and money.
Stretch wrapper machines have powered film delivery systems that typically stretch the film at a high level than hand wrapping. In most cases, this creates a cost savings of anywhere from 25% – 40% because less film is needed to contain the pallet (B2BInd). Alternatively, most workers operating hand-held stretch films rarely stretch film more than 50 percent during the hand wrap process. A nationwide evaluation of hand wrapping in real-life situations found that the average person stretches hand wrap less than 15%, thereby hindering the stretch film’s ability to effectively hold a shifting load (B2BInd). When pallets aren’t wrapped tightly enough, they are likely to fall apart causing damage to other products as well. With hand wrapping, an operator has the potential to wrap several loads, but the performance of a machine is much more reliable.
If you’re experiencing any of these drawbacks, it might be time to upgrade a stretch wrapping machine. For more information, visit our website or give us a call at (888) 930 BEST
