Banding vs shrink wrap: Comparing material use and future readiness

Shrink wrap and banding can both be used to keep products together, but they do so in very different ways. Shrink wrap generally covers the entire product or bundle in film, while banding uses a narrow strip of paper or film around only part of it.

At first, that may seem like a relatively small difference. But the amount of packaging you put around every product has consequences further down the line. It determines how much material you consume, how much packaging eventually becomes waste and, increasingly, how well the packaging fits with changing requirements around material reduction and recyclability.

Does the whole product really need to be wrapped?

For some products, the answer is clearly yes. Shrink wrap can provide protection against dust, moisture and movement, and where full enclosure is part of the packaging function, that additional coverage serves a clear purpose.

But not every bundle needs to be completely enclosed simply to keep the products together. In those applications, banding takes a more targeted approach. A narrow strip of banding material is wrapped around the product or bundle, tensioned and sealed to form a secure band around it. Instead of covering the entire surface, material is used only where it is needed to provide the required hold.

That difference leads to a fairly simple principle: use enough packaging to do the job, without automatically wrapping the parts of the product that do not need to be covered.

Less material on every bundle

This difference in coverage directly affects material consumption. With shrink wrap, the amount of film required is largely determined by the dimensions and total surface area of the bundle. The larger the bundle, the more film is generally needed to surround it.

Banding only covers a relatively small part of that same surface. As a result, considerably less packaging material may be needed to keep the products together, depending on the application.

On a single bundle, the difference may not look particularly significant. Across a production line handling thousands of bundles a day, however, the numbers start to add up. Less material per bundle means less packaging needs to be purchased, stored and handled before it even reaches the product.

Less in also means less out

What goes onto the product eventually has to come off again, so material reduction also has a direct effect on the amount of packaging entering the waste stream.

If a bundle can be held securely with a narrow band instead of a full layer of shrink film, there is simply less secondary packaging left to dispose of or recycle afterwards. That makes reducing material at the source particularly relevant, because the waste is avoided rather than dealt with later.

Again, scale matters. Saving a relatively small amount of material on one bundle may not transform a packaging operation, but making that same saving thousands or millions of times over the course of a year can have a much larger impact.

More choice in the material you use

Material reduction is one part of the discussion. The type of material being used is another.

Shrink wrap is generally made from plastic film. Banding gives manufacturers the option of using either paper or film, depending on the product, production environment and performance required from the banding material.

That flexibility means reducing material does not necessarily require giving up the properties of film. Film banding can still provide strength and durability while using material only around a small part of the bundle. Where the objective is to move away from plastic altogether, paper banding can offer another option if the application allows it.

The right choice therefore depends on what the packaging needs to withstand. A dry product may have very different requirements from something exposed to moisture, cold, or demanding handling conditions.

Less packaging leaves more of the product visible

Using less material also changes how the finished product looks.

Shrink film covers the entire bundle, even when the film itself is transparent. A band leaves most of the primary packaging uncovered, allowing the original product and packaging design to remain much more visible.

That can be particularly useful for products where appearance plays an important role in the buying decision. Branding, product information and other communication can still be printed on the band without adding another full layer around the pack.

Instead of the secondary packaging becoming the dominant part of the presentation, the product itself can remain at the centre.

Material efficiency is becoming more important

These questions around material use are also becoming more relevant as packaging legislation changes. In Europe, the Packaging and Packaging Waste Regulation (PPWR) puts greater emphasis on topics such as packaging minimisation, recyclability and designing packaging with its end of life in mind.

That does not mean that banding is automatically compliant while shrink wrap is not. Packaging compliance depends on the complete packaging concept, its materials, its function and how it will be handled after use.

What is changing is the type of questions manufacturers need to ask when evaluating packaging. Is every component necessary? Could the same function be achieved with less material? How does the packaging fit into the recycling strategy of the complete pack?

Those are increasingly important considerations when making packaging decisions for the years ahead.

Start with what the packaging needs to do

Ultimately, comparing shrink wrap with banding should not start with a debate about paper versus plastic. It should start with the function the packaging needs to perform.

If a product needs complete protection from dust, moisture or movement, shrink wrap may be the logical solution because the full enclosure has a clear purpose. But if the main objective is to keep products together, bundle them or add branding and information, covering the entire bundle may be more packaging than the application requires.

That makes the most useful starting point a simple question:

Does the product really need to be fully wrapped, or can the same function be achieved with less packaging?
