Keys to automatic strapping: more than a holding solution

Strapping is undoubtedly one of the preferred packaging systems for securing boxes, packages and palletised loads. For many companies it is an indispensable and irreplaceable system, but which are the advantages beyond securing the load? Today we analyse the importance of strapping in the final packaging and the advantages of the automatic strapping system at the end of the line.

Is it necessary to strap the load?

The answer always depends on the product, its primary packaging and the handling it will have. But in general, we always recommend strapping a load that is very fragile and/or heavy or that has instability problems in being handled and transported.

In a factory with boxed or bundled product, it is always recommended to strap the load at different levels to ensure maximum support for handling:

  • First strapping level: when we strap the heavy and/or fragile box or package to prevent it from opening.
  • Second strapping level: when we strap the palletised load, i.e. we fasten and join the palletised product to the pallet, to guarantee its stability during transport. At this point, there are two basic types of strapping: horizontal strapping (which serves to compact the load into a block) and vertical strapping (which serves to secure the load to the pallet).

When strapping pallet loads, there are also systems to protect the load itself from the strapping application, such as edge protectors.

Can strapping be replaced by other packaging systems? The generic answer is yes, although the results will not be the same as with strapping. Depending on the level of securing, it could be replaced by tape sealing (lighter loads) or film wrapping (heavier loads). Below we will explain the differences between securing a palletised load with strapping or with a wrapping machine.

What are the differences in securing the load with strapping vs. wrapping?

In palletised loads, both strapping and stretch wrapping systems can be used for the same securing purpose. However, depending on the product and purpose of the packaging, strapping has clear advantages over the stretch wrapping system.

The big disadvantage of stretch wrapping compared to strapping is the cost of consumables, which depending on the desired result can consume more film than the strap being used.

  • Strapping system: As we have seen, strapping is the most recommended system for heavy loads, as it allows for a greater degree of securing. The tension of the strap can be adapted according to the type of load and dimensions of the pallet, as well as adjusting the number of straps.  For long term storage, strapping is also more resistant to climatic conditions. If strapping is carried out by resistance welding, as in the case of Innova solutions, it also ensures a greater adherence.

The major advantage of strapping over wrapping is that it allows for the use of less consumables, thus contributing to lower costs and greater environmental sustainability.

Strapping systems: The advantages beyond strapping

We have talked about securing, but what other advantages does this system offer us in the packaging of our loads?

  • Compaction of the heavy load:

Strapping is primarily used to form a more solid and compact load, especially for heavy and/or large loads. Good compacting with strapping will prevent the load from shifting or breaking during transport, even if it does not have additional packaging systems such as wrapping or stretch hood.

  • Maximum safety and regulatory compliance:

Strapping ensures maximum cargo security during transport and handling, not only to minimise breakages and prevent losses, but also to comply with cargo stowage regulations, which require cargo to be strapped and/or wrapped.

  • Better presentation of the palletised product

Strapping also provides an impeccable presentation of the load compared to other systems such as the wrapping machine. Furthermore, the strapping can be customised according to the company’s corporate image with colours and printed logo, or even with transparent strapping to better show the contents of the product.

Our automatic strapping systems for the end of the line

Whether in the final packaging or palletizsing line, at Innova we offer automatic strapping systems for the end of the line characterized by their robustness and safety in the strapping process.

Automatic horizontal strapping machine:

The Innova horizontal strapping system has an anti-vibration portal frame composed of 4 pillars that offers greater robustness and safety in the strapping process than similar systems from other manufacturers. In addition, it also includes an automatic compactor to unify the load as block.

Automatic vertical strapping machine:

Compared to other manufacturers, Innova’s vertical strapping system includes a 90º turning system for strapping in one or two directions, on 2 or 4 sides, to guarantee better load securing.  This strapping machine model also includes a displacement system to perform several strapping operations without moving the pallet, a very useful feature for unstable loads.

Automatic Box Strapping Machine

For the palletising line, we also offer a box strapping machine, which stands out for its efficiency, robustness and ease of use. Strapping is carried out by resistance welding and the strap tension can be adjusted according to the load. In addition, its robust structure with a strapping frame anchored to the floor provides greater stability in the strapping of the boxes.

In short, as we have seen, the strapping system is essential to guarantee the securing and safety of the palletised load during transport. At Innova we offer automatic, robust but versatile strapping solutions that adapt to the packaging and securing needs of our customers. Ask for more information without obligation or commitment, we will be happy to help you.
