Void fillers are materials used inside packaging to fill empty spaces, preventing product movement and damage during transit. Common types include paper, foam, air pillows and other options. They enhance product protection, improve customer experience, and reduce the risk of returns due to damage.
A void filler is the additional material that that's used to fill the empty space inside your packaging. Void fillers help keep your product in place, prevent it from being shifted around during transit, and also protects your products from breaking. To choose the right type of void filler for your packaging, you'll need to consider how well it cushions your products, how much padding/protection your product needs, and the weight of your product.
Consider also using custom box inserts to keep your products in place when shipping!
