1. How does an arm stretch wrapping machine work?

The arm stretch wrapper is an automatic wrapping system that operates via a column that rotates around the palletized load, applying stretch film while the load remains stationary. This type of system can be installed on a two- or four-column frame, depending on the stability and production level required.

The major advantage of this system is that, by keeping the load immobile, it becomes the ideal solution for fragile, unstable, or heavy products. In short, the arm wrapping system combines protection, versatility, and performance, ensuring safe and uniform wrapping across all load types.

2. What production speed does it reach?

One of the great advantages of the arm stretch wrapper is its operating speed. Innova’s machine is capable of wrapping a full pallet in just 32 seconds, and the complete cycle (including transport) in 48 seconds, guaranteeing a uniform application of film without compromising load safety.

Thanks to this wrapping speed, the arm wrapping system can reach a production rate of up to 80 pallets/hour. It’s a perfect solution for plants with high productivity volumes seeking a balance between throughput and load protection. In addition, Innova offers the possibility of equipping the machine with a double film carriage and two wrapping arms, which further increases the speed and effectiveness of the system.

3. What types of wrapping can it perform?

This arm stretch wrapping machine offers great versatility in its wrapping cycles. Thanks to its advanced control system, it is possible to program different tension levels, number of turns, and specific reinforcements in different areas of the load, ensuring each pallet receives the protection appropriate to its characteristics. Some examples are:

• Base reinforcement: For light or unstable loads, the wrapper can be programmed to reinforce the base of the load—either with film or with the help of the reinforcement cord—thus securing it to the pallet during transport.

• Top reinforcement: For tall loads, a cycle can be configured to cover the entire load with reinforcements in various zones, specifically at the overlap of the top film.

• Reinforcement cord: This system transforms the film into a plastic cord, reinforcing the hold of the wrapping. It acts like a strap, providing greater compaction and an extra level of security for the load.

4. What characteristics should the film have?

The arm stretch wrapper uses stretch film (Stretch Film) composed of linear low-density polyethylene (LLDPE). This type of film can operate with a pre-stretch system of up to 400%, allowing substantial savings in consumables and greater sustainability in the packaging process.

It is essential to use high-quality stretch films that meet the manufacturer’s recommended specifications. Using unsuitable materials can cause jams, increase component wear, or even damage the machine.

5. What types of wrapping finishes can it deliver?

Many wrappers on the market finish the wrapping cycle by applying heat or adhesive. However, these systems can generate drawbacks such as higher energy consumption, adhesive residues on the pallet, or limitations in environments where heat is not recommended for safety reasons.

Innova Group’s arm stretch wrapping machine avoids these problems thanks to its patented Rope Gripping tying technology, which allows the cycle to finish more quickly, cleanly, and safely. Besides avoiding maintenance issues related to thermal welding systems, it eliminates thermal risks and is perfect for heat-sensitive products in sectors such as food, pharmaceuticals, or chemicals.

6. How does it adapt to loads of different sizes and shapes?

The automatic arm stretch wrapper is designed to adapt to loads of different sizes and shapes thanks to its modular structure and the availability of different models according to production needs. Innova’s arm wrapping systems can wrap loads ranging from 500 mm up to 2,400 mm, and can be adjusted to even larger dimensions if the client requires it. Furthermore, its robust four-pillar structure provides greater stability during wrapping—one of the most sought-after advantages in high-speed, high-production lines.

This versatility makes it the perfect solution for multiple industrial sectors and very diverse loads, such as big bags in the chemical industry, large-format ceramic loads that require extra securing and protection, or light and sensitive loads in sectors like food and pharmaceuticals.

7. What maintenance does the arm stretch wrapper require?

The automatic arm wrapping system stands out for its reduced number of moving components, which directly translates into ease of maintenance. By having fewer wear-prone elements than other packaging systems, maintenance is simpler and less frequent.

Nevertheless, as with any packaging system, it remains important to implement a preventive maintenance plan to ensure proper performance over time. This plan should include basic routines like periodic cleaning, lubrication of moving parts, mechanical adjustments, safety inspections, and control software updates, among other tasks. All of these actions help prevent breakdowns, ensure continuous operation, and optimize machine performance.

8. How is it integrated into an automatic packaging line?

The arm wrapping system is designed to integrate into automatic lines alongside complementary packaging systems such as strapping or Stretch Hood, forming part of a complete end-of-line solution.

Thanks to its modular design and advanced PLC control, it can be synchronized with the other equipment in the line, optimizing pallet flow and ensuring continuous production without bottlenecks.

9. What accessories can it incorporate to improve wrapping?

The arm stretch wrapping machine can be equipped with a wide range of accessories to improve the safety and protection of the load. In addition to the reinforcement cord described earlier, some of the most common accessories for this packaging solution are:

• Top hold-down press: For light or unstable loads, the wrapper can include a top press that holds the load while wrapping is performed.

• Top cover application: For loads that require full protection. The top cover uses a different consumable than stretch film, with protective properties that overlap the wrapping.

• Edge protector applicator: For special loads that require corner protection, vertical cardboard edge protectors can be applied.

10. What models of arm wrapping system are available?

There are several models of arm wrapping systems on the market, designed to cover different production needs and load types. At Innova Group, the range mainly consists of two versions that provide solutions adapted to different levels of demand: AWS|Pro and AWS Techlite.

• AWS|Pro: This model incorporates all the features covered in this article—high wrapping speed, robust four-pillar structure, the possibility of including accessories such as edge protectors or top covers… an ideal option for medium- and high-production lines.

• AWS Techlite: Innova’s AWS Techlite is a lighter, more compact, and more efficient version of the arm wrapping system, designed to suit medium- or low-production lines. Its simplified, modular structure facilitates installation, transport, and space savings on the factory floor. With a productivity of up to 40 pallets per hour, it preserves quality and reliability while offering a more sustainable and efficient approach.

In short, the automatic arm wrapping system is one of the most efficient, safe, and versatile packaging solutions for various industrial sectors. Its ability to handle loads of different shapes and sizes, along with its production speed and easy maintenance, makes it a reliable choice for optimizing any end-of-line process.
