Box Fillers and Void Fill Packaging

A box filler, also called void fill, is packaging material used to occupy empty space inside a shipping carton. It prevents products from shifting during transit, reducing the risk of damage. Common options include loose fill peanuts, paper cushioning, bubble wrap, foam, and inflatable air pillows, each suited to different product types and protection levels.

For lightweight items, air pillows or loose fill peanuts work well and inflate or pack quickly. Paper void fill offers an eco-friendly, curbside-recyclable alternative. Fragile or electronic items benefit from bubble wrap or foam protection, while wine and specialty bottles require form-fitting inflatable bottle bags for secure void fill.

Shipping boxes can be filled with loose fill peanuts, kraft paper, bubble wrap, foam sheets, or rapid-fill air pillows depending on the product's weight, fragility, and value. Electronics should use anti-static (ESD) materials, while eco-conscious shippers often choose biodegradable cornstarch peanuts or recyclable paper cushioning.

Packing peanuts are loose-fill pieces poured directly into cartons, available in biodegradable cornstarch or anti-static EPS variants. Air pillows are pre-filled or machine-inflated plastic pouches that inflate in seconds, ship flat to save storage space, and are made from recyclable LDPE film—ideal for high-volume, space-conscious fulfillment operations.

Yes, several options are eco-friendly: biodegradable cornstarch peanuts dissolve in water, kraft paper void fill and Geami paper wrap are curbside recyclable, and Rapid Fill air pillows use recyclable LDPE film. These materials help brands meet sustainability targets without compromising protective performance.

For electronics and sensitive components, use ESD-safe (anti-static) materials such as anti-static EPS packing peanuts or anti-static bubble wrap. These prevent electrostatic discharge that can damage circuit boards and electronic parts, ensuring components arrive safely without static-related failures during transit and handling.
