Void Fill Packaging in Australia: What It Is, Why It Matters & How to Choose the Right Type

Smart packaging choices that protect your products and your reputation.

Updated: November 2025

Packaging Is Not Just the Box. It Is What Is Inside That Counts

When you send a product, it is not only the contents that matter. It is how well they are protected in transit. Void fill packaging refers to materials that fill the empty space inside a carton or mailer so that goods do not shift, rub or break on the way to your customer.

For Australian businesses shipping everything from fragile electronics to homewares, the right void fill strategy means safer deliveries, fewer returns and a smoother customer experience. It is also a practical way to align your brand with modern expectations around sustainability and the Australian Packaging Covenant Organisation (APCO) guidelines.

Paper based void fill systems such as the Ranpak range are a key part of this shift. They give you on demand, curbside recyclable protection that works for both ecommerce and industrial goods.

If you want to see the types of products available, you can browse our void fill category or our Ranpak paper void fill options.

A Quick Look: What Is Void Fill Used For?

  • Cushion fragile or irregularly shaped products inside the carton.
  • Prevent items from rattling, rubbing or breaking in transit.
  • Help improve presentation during unboxing and reduce “box too big” complaints.
  • Support compliance with courier handling requirements by reducing damage risk.
  • Reduce environmental impact when you choose recyclable or compostable options.

Common Void Fill Options and Where They Work Best

Different products need different levels of protection. Below is a plain language look at some of the most widely used options and when they make sense in an Australian context, with a focus on how Ranpak paper systems can replace traditional plastics.

1. Packing Paper and Paper Void Fill (Ranpak)

Simple, familiar and effective. Kraft packing paper is widely used in ecommerce, retail and industrial goods. It works for wrapping, interleaving and crumpled void fill around a wide variety of products, from books and bottles to automotive parts.

Ranpak systems such as FillPak TT, FillPak Trident and FillPak Mini convert compact kraft paper fanfold into high yield void fill at the packing bench. The paper is curbside recyclable in most Australian councils and helps you move away from unnecessary plastic air pillows.

You can see examples in our Ranpak void fill paper guide and our paper void fill category.

2. Air Pillows and Inflatable Systems

Air pillows are small plastic cushions filled with air and sealed in sections. They are ideal for filling empty space around products that are already in an inner carton or protective pouch. Their main advantages are very low weight and high yield per carton.

In Australia, most air pillows are made from low density polyethylene film (LDPE 4). They are often suitable for store drop off or specialised soft plastic recycling where programs exist, but they should not be placed in standard household recycling bins unless your local council specifically allows it. Many businesses now use inflatable systems alongside paper void fill so they can gradually reduce plastic use without disrupting operations.

3. Biodegradable Packing Peanuts and Loose Fill

Traditional peanuts were made from expanded polystyrene. Many Australian suppliers now use starch based “biofill” peanuts that dissolve in water and can be composted in a suitable home compost system. These are useful for filling voids around irregular shapes or mixed shipments.

At Power Packaging, our Biofill biodegradable void fill is made from natural starch, contains no added toxic ingredients and can be broken down with water. It is a strong option if you want to move away from polystyrene and still maintain good cushioning performance.

4. Bubble Wrap and Eco Bubble Options

Bubble wrap remains a go to for highly fragile items such as glassware, ceramics and electronics. It provides both cushioning and surface protection. For businesses focused on sustainability, look for options with recycled content or thinner, high performance films that use less plastic for the same protection.

Our bubble wrap rolls and eco friendly bubble wrap range give you options that balance protection, cost and environmental impact.

How to Choose the Right Void Fill

  • Fragile or high value items
    Combine bubble wrap or paper cushioning with a stable void fill such as crumpled paper or Biofill.
  • Lightweight goods
    Air pillows or soft paper void fill protect the product without adding unnecessary weight to freight.
  • Heavier or dense items
    Use stronger materials such as paper cushioning from systems like Ranpak PadPak to create blocking and bracing.
  • Eco priorities
    Choose curbside recyclable paper, certified compostable starch peanuts or paper based cushioning systems. Ranpak paper is a popular option where businesses want to remove plastic void fill while keeping strong protection.
  • Unboxing and brand experience
    For retail and ecommerce, consistent and neat void fill helps your product feel more premium and reduces the sense of over packaging.

For higher volume operations, automated systems such as Ranpak FillPak TT, FillPak Mini and on demand inflatable bubble systems can reduce labour time and improve packing consistency.

Why Many Businesses Are Switching to Ranpak Paper Systems

Power Packaging supplies the full Ranpak range of paper based void fill and cushioning systems. These solutions are popular with Australian warehouses and ecommerce operations because they are easy for packers to use and easy for customers to recycle.

  • FillPak for fast, high yield void fill in shippers and cartons.
  • PadPak for heavy items and cushioning that needs real holding power.
  • Geami for retail friendly wrapping that replaces bubble wrap with paper honeycomb.
  • WrapPak for thermal and surface protection needs.

Our team can recommend a Ranpak combination that suits your mix of SKUs, damage rates and sustainability goals. You can also explore the range on our Ranpak paper packaging page.

Real World Applications: Who Uses Void Fill and How

Ecommerce and Online Retailers

From boutique skincare to electronics and homewares, ecommerce brands use void fill to prevent damage and keep cartons compact. Ranpak paper is often used at pack benches for fast, tidy fill that customers can recycle.

Retail and Gift Packaging

Retailers often use coloured paper or tidy paper void fill instead of plastic based options. Geami wrapping gives a premium, gift ready look while still using paper only materials.

Electronics and Technology

High value electronics are usually packed in custom inserts, with void fill such as paper, inflatable cushioning or bubble used around the inner carton. Anti static options are used where components are sensitive.

Moving and Relocation

Packing paper and loose fill help protect a mix of household items in moving cartons. Proper void fill minimises movement in the carton so objects do not grind against one another.

Industrial and Heavy Goods

Manufacturers use paper cushioning, blocking and bracing techniques and sometimes timber or foam to keep heavy items from shifting or damaging the carton.

Trends and Innovations in Void Fill

Across Australia, businesses are moving away from unnecessary single use plastics and towards paper based systems, certified compostable fillers and automated machinery. APCO’s Sustainable Packaging Guidelines and the 2025 National Packaging Targets encourage companies to design packaging that is recyclable, reusable or compostable and to phase out problematic plastics where practical.

In practical terms, that has led to growth in solutions such as:

  • Paper based void fill systems like Ranpak paper packaging, which use renewable paper and are widely recyclable.
  • Bio based loose fill using starch rather than polystyrene, as seen with our Biofill products.
  • Inflatable systems with recycled content and thinner films that use less plastic for the same performance.
  • Internal recycling loops, for example converting offcut cardboard into low cost void fill for internal shipments.

Some states are also introducing controls on expanded polystyrene packaging, which encourages a shift to paper and certified compostable solutions for cushioning and void fill.

Frequently Asked Questions

Is biodegradable void fill actually compostable in Australia?
Not all biodegradable products are compostable, and not all compostable products are suitable for home composting. In Australia, look for recognised certifications such as AS 4736 (industrially compostable) or AS 5810 (home compostable) and the corresponding Australasian Bioplastics Association logos on the packaging. Without certification, “biodegradable” may only mean it breaks down into smaller pieces over time rather than fully composting.
Which void fill is best for fragile shipping?
There is no single perfect answer, but a combination usually works best. For example, wrap fragile items in bubble wrap or paper cushioning, then use crumpled paper or Biofill peanuts to stop movement in the carton. For very delicate items, consider custom inserts plus additional void fill in any remaining gaps.
Can I automate void fill in my warehouse?
Yes. Systems such as Ranpak FillPak TT, FillPak Mini, PadPak cushioning and on demand inflatable film systems can deliver consistent void fill at the touch of a pedal or button. This usually leads to faster packing times and more consistent material usage per carton.
Is paper always better than plastic for void fill?
Paper is often easier for customers to recycle through kerbside recycling and is made from a renewable resource. However, very lightweight plastic systems can sometimes offer lower transport emissions per pack. The best choice depends on your product fragility, freight profile and sustainability priorities. A good starting point is to remove unnecessary plastic, then use paper or high recycled content materials where they are fit for purpose.
