When you’re shipping products, the empty space inside a box can be a real problem. This space, known as “void,” allows items to shift, bump, and break during transit. That’s where void fill comes in. It’s the material you use to fill these gaps, securing your products and ensuring they arrive safely. With so many options available, understanding the different types of void fill is key to protecting your shipments and managing costs.
Bubble Wrap
Bubble wrap is one of the most recognizable and effective void fills available. Its signature air-filled pockets provide excellent cushioning, absorbing shocks and protecting items from impact. This makes it ideal for fragile products like glassware, electronics, or ceramics. You can easily wrap it around items of various shapes and sizes for a secure layer of protection. While highly effective, it can be bulkier and take up more storage space compared to other options.
Packing Peanuts
Packing peanuts are small, lightweight pieces that interlock to fill empty spaces and prevent items from shifting. They are great for irregularly shaped items that are difficult to wrap. Manufacturers traditionally make packing peanuts from polystyrene, but more eco-friendly versions made from cornstarch are now widely available. These biodegradable peanuts dissolve in water, making them a more sustainable choice. However, they can be messy to handle and may not be suitable for heavy items that can crush them.
Foam Inserts
For maximum protection of high-value or delicate items, custom foam inserts are an excellent solution. These inserts fit the exact shape of your product, holding it securely in place and providing superior shock absorption. This makes them a popular choice for electronics, medical equipment, and other sensitive goods. While they offer unparalleled protection, foam inserts are a more expensive option and require a custom design for each product, which can add to lead times.
Inflatable Air Pillows
Inflatable air pillows are a modern and efficient void fill solution. They come flat on a roll and inflate on-demand, saving significant storage space. As they are mostly air, they are incredibly lightweight, which helps keep shipping costs down. Air pillows are great for filling large voids quickly and are best suited for bracing and cushioning products that are already in their own packaging. They are a clean, dust-free option that provides reliable protection.
Kraft Paper
Kraft paper is a versatile and eco-friendly void fill. You can crumple it up to fill empty spaces, wrap it around items for surface protection, or use it as a divider. One of the main benefits of using paper as void fill is its recyclability and biodegradability, which appeals to environmentally conscious consumers. It provides good, basic protection and is strong enough to brace items in place, making it a reliable solution for many different types of products.
Choosing the right void fill is crucial for ensuring your products reach their destination in perfect condition. By understanding the different types of void fill and their unique benefits, you can make an informed decision that protects your items, satisfies your customers, and fits your budget.
