Complete your packaging with the right void fill materials. Choose from bubble wrap, packing peanuts, cardboard, or paper. Tip: go for an eco-friendly option, such as biodegradable packing peanuts or recycled cardboard.
WHY RISK RETURNS WHEN YOU CAN SHIP IT SAFE?
A box that closely fits the product ensures it doesn’t shift and stays stable. In that case, void fill isn’t always needed. The same applies if the product itself is not fragile or already has solid product packaging. When is it necessary? When extra protection is required or when contents must not move around.
In short, there are only a few commonly used void fill materials: shredded cardboard, bubble wrap, plastic air pillows, packing peanuts, and paper. Each comes with its own strengths and limitations.
The best protection for fragile products is a combination of two materials: bubble wrap and packing peanuts. First, fill part of the box with packing peanuts. Then wrap the product itself in bubble wrap and place it inside. Add more packing peanuts around it until the box is completely filled. The peanuts keep everything stable and absorb external pressure.
Do you mainly want to prevent products from shifting? Shredded cardboard mats or packing paper are sufficient. Shredded cardboard consists of repurposed sheets cut into flexible mats. They provide cushioning while keeping products from sliding. Packing paper is another option, it offers less protection but is lightweight. Both materials work best when placed underneath, around, and on top of the product.
Void fill can also improve presentation. Shredded cardboard already has a neat appearance, while kraft paper gives shipments a natural, premium look. A clothing item shipped in a plastic bag feels different compared to one wrapped in kraft paper. In this way, void fill also adds a branding function.
Natural materials like paper and cardboard are considered sustainable. Recycled materials are greener, biodegradable materials add another eco advantage, and reused materials are even more sustainable, as no new resources are needed. At RENUBOX, we promote sustainable solutions — provided the material still protects as intended.
As you may have guessed, there is no single “best” solution. It depends on your products and the level of protection required. In some cases, using nothing at all is actually the greenest option. Prefer to avoid void fill entirely? Consider a Tailored box — a custom-sized box that reduces the need for fillers altogether.
