The stretch wrapping system is one of the most widespread and widely used final packaging solutions to protect loads. There is a wide range of wrapping machine types with different applications and complements, depending on the product and the customer’s objective. Therefore, when choosing a pallet stretch wrapper for a packaging project, many questions arise that, as manufacturers of this system, we receive and handle on a daily basis.
With competitive price and timely delivery, SMART WASP sincerely hope to be your supplier and partner.
In today’s article, we will answer some of these questions and doubts about the automatic wrapping system, continuing our series of Top 10 Frequently Asked Questions.
Due to its long extension in the market, there is a multitude of stretch wrapping models according to the needs and functionalities sought in the packaging process. Even so, leaving aside manual wrapping processes, we find large categories such as:
The main differentiation is the automation component. While a semi-automatic (turntable or robot) pallet stretch wrapper needs human intervention to start the cycle, the automatic pallet stretch wrapper is part of a fully automated line. On the other hand, while the semi-automatic platform stretch wrapper can be installed anywhere in the factory, its automatic variant needs a conveyor line that allows pallets to flow in and out.
Finally, automatic stretch wrappers usually offer more features such as safety extras, higher speed, accessories, etc.
Usually, for low production (less than 20 pallets/hour), we recommend semi-automatic pallet stretch wrappers, as they offer versatility yet higher wrapping quality than a robot stretch wrapper.
For a range of 30 – 40 pallets/hour, we can already recommend an automatic stretch wrapper which can be either a rotary arm or a low-production ring wrapper.
For higher outputs of 40 pallets/hour or specific wrapping requirements, the reliable choice will be a high-performance ring wrapper. High outputs of 80 – 100 pallets/hour typically use double film carriage stretch wrappers for higher speed.
Depending on the product and packaging objectives, different types of cycles can be designed. The versatility of stretch wrapping is precisely the fact that it is possible to program a wrapper with different tension and reinforcements in the various areas of the load. Some examples of these can be:
Usually, the pallet wrapping machines use stretch film, but they can also employ pre-stretched film or other new consumables on the market, such as kraft paper with stretching capabilities.
The standard stretch film is composed of low-density line polyethylene (LLDPE) which is what gives it its high stretch capacity. Depending on the characteristics of the plastic and the stretch wrapper (and its pre-stretching system) this type of film can stretch between 25 and 300%. If both the film and the stretch wrapper allow a higher stretching (more than 150%), allowing also a higher saving.
The pre-stretched film is a film that has already been stretched to its shrinkage limit (which is usually 100%) and is normally used in manual or semi-automatic applications without pre-stretching and low tension. It is a non-stretch film recommended for loads that need slight protection or restraint.
Lastly, stretch kraft paper fulfills a similar function to pre-stretched film, with the great difference that it has a lower stretching capacity and does not allow the application of a rope system. Even so, it has recently appeared on the market as a more sustainable alternative to film, since it is 100% recyclable.
Film usage in a pallet stretch wrapper depends on many factors: type of stretch film, if it is stretchable, pre-stretched, or not, and its stretching capacity, but also the features of the stretch wrapper, the wrapping cycle, rope application, cover, load size… the list is almost endless. Even so, several factors make it possible to economize and optimize the film to the maximum:
The automatic stretch wrapper system can run a cycle that covers from the base to the top of the pallet, where a cover is placed to fully protect the load. The cycle can be programmed with higher tension to ensure that no layer is detached and that the wrapping is compact and sealed.
However, an alternative for total protection in automated productions with medium-high production is usually Stretch Hood wrapping, which covers the entire load with a single layer of film.
In the case of automatic stretch wrappers, a standard wrapping can perform between 60-80 pallets/hour. For speeds of 80-100 pallets/hour, ring wrapping with two reel carriages is recommended. And more than 100 pallets/hour and up to 200 p/h are achieved with high-performance stretch wrappers but also depending on the type of load and wrapping requirements.
As this is such a broadly defined aspect, we recommend consulting with an expert team in packaging, such as Innova’s, to determine which type of stretch wrapper or packaging system is best suited to your production.
Although most stretch wrapping equipment works with palletized loads, pallets loads can also be packaged employing a special accessory. In automatic stretch wrappers, a conveyor-lift system is usually included to raise the load so that the wrapping carriage can reach its base and protect it.
The pallet wrapping system is one of the most extensive and technologically evolved solutions in recent years. For this reason, it is a very versatile system that allows to include a multitude of accessories to improve the wrapping according to the wrapping objectives.
Some of the most common accessories of automatic wrapping machines:
At Innova we have developed an accessory to include the edge protectors automatically during stretch wrapping:
Fully automatic pallet wrapping machines are an indispensable tool for modern logistics and warehouse operations. They simplify the process of securing goods for transport, ensuring safety and efficiency. However, many potential users have questions about how these machines work, their benefits, and how to select the right model. Here, we address the top questions about fully automatic pallet wrapping machines.
A fully automatic pallet wrapping machine is an advanced device designed to wrap stretch film around pallets or loads without requiring manual intervention. Unlike semi-automatic models, fully automatic machines handle the entire process, including film application, wrapping, and cutting. This hands-free operation makes them ideal for high-volume operations.
The machine operates using a programmed system that automates every step of the wrapping process:
Loading: The pallet is placed on the machine's turntable or conveyor, either manually or via a forklift.
Film Application: The machine secures the film to the pallet automatically.
Wrapping: The turntable rotates, or the film carriage moves, wrapping the load in stretch film according to preset parameters.
Cutting and Sealing: After wrapping, the machine cuts and seals the film, ensuring a neat and secure finish.

Consistency: Fully automatic machines ensure uniform wrapping for all pallets, enhancing stability and load security.
Labor Savings: They free up workers for other tasks, improving overall productivity.
Safety: Automated systems reduce the risk of injuries associated with manual wrapping.
Fully automatic pallet wrapping machines come in various configurations to suit different needs:
Turntable Wrappers: The pallet is placed on a rotating turntable while the film carriage moves up and down.
Rotary Arm Wrappers: The wrapping arm rotates around the stationary pallet, making them suitable for heavier or unstable loads.
Ring Wrappers: These machines have a ring-shaped carriage that moves around the pallet, offering high-speed wrapping.
Inline Wrappers: Designed for integration with conveyor systems, these are ideal for fully automated production lines.
When selecting a fully automatic pallet wrapping machine, consider the following features:
Capacity: Ensure the machine can handle the size, weight, and number of pallets you need to wrap daily.
Film Pre-Stretch: Pre-stretch mechanisms reduce film usage and improve load stability.
Control System: Look for user-friendly controls and programmable settings for different wrapping patterns.
Safety Features: Ensure the machine includes emergency stop buttons, safety guards, and sensors to protect operators.
