Voil fill, packaging filler, shipping padding, box cushioning.
It goes by many names, but it all serves the same purpose.
Void filler has the primary role of keeping the contents of your mailer box safe and secure.
Packaging fillers also play an aesthetic role. That is, it doesn't hurt if they also look pretty.
There are just as many types of internal padding for a box as there are names for it.
And in this article, we'll take a look at some of the most popular types and analyse:
- Protection potential
- Visual appear
- Environmental impact
Let's get straight into it!
What exactly is packaging filler?
In general, void fill or packaging fillers can be described as something that's put into a shipping box to add protection against drops by taking up empty space inside the box.
Good void filler protects against the rigours of transport, like being bounced around in the back of a delivery van, or thrown onto your doorstep by a lazy courier.
Many forms of cushioning can now be customised in terms of print, size, shape, texture.

Attention to detail, like branded packaging fillers, create a complete end-to-end brand experience for your customer, and are certainly worth looking into if you want to blow your customer's mind!
When do I need to use a void filler?
It's a common misconception to think that you only need to use packaging fillers to protect fragile items.
The truth is that if you care about the visual presentation of your product to your customer, you should use some form of void filler.
Products with sharp pointy corners can easily pierce even the toughest corrugated box. Adding an extra layer of void filler or some kind of wrapping will make it tough to push through.
Similarly, heavy products can easily wear through external packaging, given the constant vibrations of road or air travel.

That is to say, there may be a lot of empty space between your product and the internal edges of its shipping packaging.
This is space that your item can move around in, and potentially get damaged.
Void filler's role is to physically fill that void and minimised the potential for movement during shipping.
So now you know what void filler is and what it has to do, take a look at it in it's most common forms:

- Adding a rustic, minimalist touch to your branding
- Wrapping up products to build unboxing anticipation
- Eco-conscious brands that want to use recycled and recyclable materials
Internal inserts are intricate pieces of cardboard that are folded in a specific way to 'present' your product when the packaging is opening.
Most new cell phones have some form of an internal insert that's been engineered to also accommodate a manual, charger, headphones and other accessories.
The strength of internal inserts is that they are made specifically to fill the space between a product, and it's packaging.
There's absolutely no movement at all.
- Products that have multiple accessories
- High-end, luxury products
- Extremely fragile and delicate products (glass, porcelain etc.)
Custom tissue paper
Customised tissue paper might not add a whole lot of protection, but it does add a lot of class to high-end luxury packaging.
Boutique fashion brands regularly use tissue paper to wrap lingerie or delicate items to add that sense of elegance and class.
Pick from over 256 tissue-paper colours and print your logo on your own custom tissue paper.
Tissue paper that's sealed closed with a sticker can prevent a sweater or blouse from unfolding during transit. That's why it's used a lot with durable products like shoes and other apparel items.
- Building an unboxing experience
- Keeping clothing folded during transit
- Ensuring that your branding is everywhere
Wood wool/wood excelsior
Another example of sustainable packaging, wood excelsior is perfect for adding internal cushioning, as well as a 'rustic', old school feel to your brand.

Nothing more than shaved, curly wood, it often has a scent that bursts out of the box.
It's worth taking note of the smell if you're using wood wool and clothing or other 'soft' products.
That being said, incorporating the sense of smell into your brand's unboxing experience may also be something you want to do!
- High-end, luxury packaging
- Involving the sense of smell
Shredded cardboard is another take on recycled packaging.
Cardboard can only be broken down and turned back into paper pulp so many times before losing it's structural integrity permanently.
Cardboard that has reached the end of it's like as typical 'cardboard' is often shredded and turned into void filler.

- Adding a sense of 'nature' and rawness to your brand
- Protecting small but relatively heavy objects
Pads and partitions are used to segregate and stabilise items inside the box. Usually made from cardboard or even a light wood, dividers are often used for small bottles, cosmetics or jars.
Partitions are used commonly in larger shipping boxes that have multiple instances of the same product or material (like glass), and you don't want them to touch during transit.
- Large, heavier shipping boxes
- Keeping multiple items separate (glass bottles etc.)
Plastic-made bags filled with air that provide a perfect cushioning solution.
However, most forms of air pillows are single-use plastic packaging and a significant blight on the environment.
Don't use these forms of void filler as it wreaks havoc on the environment.
There are, however, plastic air pillows made from plant-based biodegradable polymers.
- High-volume warehouses
- Packaging and fulfilling orders on a production line
- Brand's that don't care for the environment.
Buddle wrap can't really be customised, and like air pillows, it's usually single-use plastic packaging that's terrible for the environment.
- Brands on a budget
- High-volume fulfilment
- Stress relief
Packing peanuts are another name for the typical polystyrene foam balls that used to be used before we discovered that they're probably the worst thing possible for the environment.
Nowadays, packing peanuts are still used, but they're made from corn waste or another form of plant-based material.
These types of packing peanuts are biodegradable, but they still make just as much of a mess!
- Brands that don't want customisation
- Brands that sell fragile products in a variety of shapes and sizes
