Pallet Wrapping Machine: Types, Features and Buyer’s Guide
The automatic pallet wrapping machine is a machine designed for the automatic packing of palletized loads. The purpose of these machines is to protect and stabilize the goods on the pallets that will be shipped or storaged. The protection and the stabilization of the palletized loads is provided by the stretch film, which secures the goods on the pallets. In the next chapter, we will examine the macro-types of wrappers: automatic and semi-automatic (or manual).
Automatic pallet wrapping machine VS Semi-automatic pallet wrapping machine (or Manual)
To further clarify the difference between the 2 types of pallet stretch wrappers, let’s start by comparing: automatic pallet wrapping machines and manual pallet stretch wrappers. The first point we want to consider is that purchasing an automatic pallet wrapper will bring benefits to you and it will drastically increase the productivity of your organization.
Lower labor costs, combined with less film waste and better safety are the main reasons for you to consider an automatic pallet wrapper instead of manual or semi-automatic ones. Many companies that own a manual pallet wrapper don’t know that there have been advancements in their safety systems that can make them more reliable, which is the first reason why they should upgrade their machinery and purchase an automatic pallet wrapper.
Some manual pallet wrappers have exposed wires or motors that could injure someone. Most modern pallet stretch wrappers, on the other hand, are very safe. Another advantage of having an automatic pallet wrapper is the pre-stretching function, which is missing in the classic manual pallet wrapper.
It allows you to pre-stretch the wrapping film, which allows you to use less film; if you manually wrap 100 pallets with a roll of film, with an automatic pallet wrapper it will be possible to wrap 200 to 300 pallets. This saving of money can allow financial resources to be allocated to other company projects. Pieri’s product that implements the pre-stretching function is PEM-DUO, an electronic pre-stretch carriage with 2 motors controlled by inverter with variable pre-stretching.
The pre-stretching percentage can be varied from the electric panel (minimum 120% – maximum 500%), and is obtained by acting separately on the speeds of the motors mounted on the carriage. This feature makes it possible to exploit the characteristics of the film used to the maximum, allowing a considerable reduction in film consumption. Furthermore, the possibility of setting different pre-stretching percentage values for each program and for each phase of the wrapping cycle maximizes performance in terms of pallet load stability.
In addition to this, every company can use the automatic winder to reduce its labour costs: a manual pallet wrapper in fact requires numerous operators to be fully operational. By purchasing an automatic pallet stretch wrapper, you have the opportunity to save on labor costs since automation will take place independently, allowing operators to be assigned to activities that require more critical thinking.
Automatic Pallet Wrapping Machine for protection of the loads
An automatic pallet wrapping machine helps you pack packages, boxes and containers that need to be stored and then transported to their destination. The packaging of your products automatically wrapped by stretch film will have the following features:
- Protected from damage, dust and moisture: using an automatic pallet wrapper will ensure your goods are protected from damage by dirt, dust and moisture.
- Safer: an automatic pallet wrapper will keep the operator on the forklift which is a safety measure. In fact, according to some surveys, it seems that 20% of all accidents involve people walking on the warehouse floor.
- No wear and tear: manual pallet wrapping causes wear and tear injuries while automatic pallet wrapping allows you to protect your employees.
In addition you will be able to:
- Obtain a more efficient wrapping of the product: a manual pallet wrapper does not allow you to guarantee uniformity to the packaging. In fact, there are normally variations in the stretch and efficiency of the packaging such as to obtain an approximate packaging.
- Time saved: with the automatic pallet wrapping machine the packaging will be carried out with a considerable saving of time since you can count on a fast and reliable machine, able to speed up the packaging process drastically;
The manual pallet wrapper, on the other hand, will bring tedious, repetitive and time-consuming work to your operator.
Deepening: Semi-automatic pallet wrapping machine
We have decided to leave this type of pallet wrapper for last as it is a hybrid of the first two, which, being more iconic, deserved a greater comparison and in-depth analysis. Semi-automatic pallet stretch wrappers automatically wrap the load. The “manual” phase, on the other hand, is when the operator has to position the pallet in the wrapping area, hook the first strip of film and start the wrapping process. At the end of the wrapping process, the operator must cut the film and remove the wrapped pallet. It is recommended to purchase a semi-automatic wrapper only if you do not produce more than 20 pallets per hour. The wrapping process is automatic, but the loading and unloading part is not only time-consuming but also dangerous for the operator.

Types of automatic pallet wrappers
Ring Wrapping Machines
Rotating ring pallet wrappers differ from the other types in that the pallet remains immobile on the wrapping area, while the stretch film is rolled up on the pallet itself through a ring that surrounds it and wraps it up to its full height. With these machines it is also possible to carry out wrapping operations that differ from the traditional ones:
- wrapping only the base of the pallet and the upper part;
- wrapping two entire pallets on top of each other.
Below is a video that shows you how our ring wrappers work.

Arm Wrapping Machines
With the rotating arm stretch wrappers the wrapping system remains the same as the previous one; the only differentiating factor is that instead of the ring there is an arm that effectively wraps the pallet. Here too we propose a video that summarizes the functioning of Pieri’s rotating arm stretch wrappers.

Turntable wrapping machines
With turntable pallet wrappers, the pallet is placed directly on the turntable. Then the film is wrapped around the pallet by the pre-stretching carriage that runs along a column, while the platform rotates the pallet. Here is the illustrative video that shows you in more detail the features and operation of our turntable pallet wrapper:
They say about us
The Pieri company was founded in 1970 by a promising project of Sauro Pieri, and growing steadily every year, it came to celebrate its 40th year just last year. Born as a local business near Cesena, Pieri has grown so much that it has exported its products abroad. In fact, it’s no coincidence that important newspapers also have them, which we’ll look at below.
Pieri is on “Sole 24 Ore
The main topic of the magazine is the electronic pre-stretching exploited through the Pieri PEM-DUO product. PEM-DUO, as previously mentioned, is a motorized variable pre-stretching trolley. The pre-stretching percentage can be varied in relation to the electrical panel (minimum 120% – maximum 450%), and is obtained by modifying the speed of the motors installed on the trolley. This makes it possible to customize the winding for each type of load, leading to an evident saving in stretch film. Moreover, since this machinery can customize the wrapping for any type of product, it substantially increases the stability of the pallet and therefore decreases the risk of damaged products. The importance of this product has gained national resonance, leading many companies to adopt it in their storage processes. The consequence of this was the ad hoc article on the “Sole 24 Ore”. Here the article.
Pieri and Siemens reference
We have been collaborating with Siemens, a multinational company operating in the automation, electrification and digitalization sectors, for a few years now. Siemens periodically publishes a magazine on digital transformation in various sectors, and this year decided to dedicate an article on Pieri. After an introduction on the history and mission of the business, the article proceeds describing Pieri products, focusing in particular on AVR 400 FLEXA, an automatic ring winder that integrates with the Siemens platform thanks to the PROFINET network.
