Void fill materials are essential when shipping products in boxes that are slightly larger than their contents. These materials help secure items, prevent movement, and absorb shocks during transit. At The Packaging World, we believe that using the right void fill can protect your products, reduce returns, and improve customer satisfaction—all while keeping your packaging cost-effective and professional.
In this guide, we’ll walk you through the most common void fill materials, what they’re best for, and when to use them.
1. Kraft Paper – Versatile and Eco-Friendly
Kraft paper is one of the most widely used and affordable void fill materials. It’s made from recycled content, making it a sustainable choice.
Best for:
- Filling space in custom boxes for lightweight items
- Creating a clean, minimal presentation
- Businesses focused on eco-conscious branding
When to use:
Choose kraft paper when you want a simple, biodegradable solution that still provides light cushioning and prevents product shifting.
2. Bubble Wrap – Lightweight and Protective
Bubble wrap offers excellent cushioning and shock absorption. It’s ideal for fragile items that need extra padding.
Best for:
- Electronics, glassware, ceramics
- Wrapping individual items
- Layering between breakable pieces
When to use:
Use bubble wrap inside custom boxes when shipping anything breakable or high-value that could be damaged by vibration or impact.
3. Air Pillows – Clean and Lightweight
Air pillows are inflatable pouches that act as spacers inside boxes. They’re lightweight, neat, and easy to use.
Best for:
- Filling empty space around items
- E-commerce shipping
- Products that aren't fragile but still need to stay centered
When to use:
Choose air pillows when you want to reduce shipping weight while keeping your products from shifting in transit.
4. Packing Peanuts – Flexible Fill for Irregular Shapes
Packing peanuts can conform to any shape, providing all-around protection. They come in both traditional and biodegradable options.
Best for:
- Odd-shaped items
- Shipments with multiple products
- Heavy-duty protection
When to use:
Use packing peanuts in custom boxes when items don’t fit snugly and need cushioning from all sides.
5. Foam Inserts – Custom Protection for Fragile Products
Foam inserts are pre-cut or molded to fit your product exactly. This ensures a snug fit and optimal protection.
Best for:
- Electronics, tools, and instruments
- Luxury or high-end products
- Secure product presentation
When to use:
Use foam inserts when product protection and presentation matter equally. They're perfect for premium custom packaging.
6. Shredded Paper – Affordable and Decorative
Shredded paper fills space and adds a touch of branding flair. It's available in many colors and textures.
Best for:
- Gift packaging
- Subscription boxes
- Retail products that benefit from a personal touch
