The Real Cost of Void-Fill Per Parcel

By the Custom Air Pillows team · June 30, 2026 · 6 min read

Buyers compare void-fill on the price of a roll, but the roll price is only one line in the true cost of filling a parcel. Labor at the bench, the weight the fill adds to the shipment, and the damage rate it prevents or causes all move the real number. The cheapest roll can easily be the most expensive fill once those costs are counted.

Here is how to build an honest cost-per-parcel figure so you compare materials on what they actually cost, not just what they cost on the invoice.

Material cost

Start with the obvious line: the price of the fill itself per parcel. For air pillows this is a fraction of a cent to a few cents depending on size and gauge, because you are mostly buying air. Bubble wrap costs more per parcel for the same volume, and paper is cheap per sheet but you use a lot of it. This is the number most buyers stop at, and it is the least complete.

Labor cost

Every second a packer spends handling fill is labor you pay for. Fill that is slow to grab and place, like hand-crumpled paper, adds time to every parcel, and at scale that time is real money. Air pillows with an inflator minimize handling, so their labor line is low even when the material line is close to another option. Multiply the seconds saved per parcel by your fully loaded labor rate and daily volume to see the effect.

Damage and returns

Under-protecting a parcel is the most expensive mistake, because a damaged item costs you the replacement product, the return shipping, and often the customer. A fill that closes voids properly and holds its shape lowers the damage rate, and even a fraction of a percent improvement across thousands of parcels dwarfs the difference in roll price. This is the line where cheaping out most often backfires.

Dimensional weight

Carriers bill on dimensional weight as well as actual weight, so heavier fill can raise the price of the shipment itself. Paper adds real weight; bubble adds some; air pillows add almost none. If your lanes are weight-sensitive, a lighter fill can save more on freight than it costs in material.

Cost line	Air pillows	Bubble wrap	Paper void-fill
Material per parcel	Lowest	Higher	Low
Labor to place	Low (inflator)	Low to medium	Highest (crumple)
Added parcel weight	Negligible	Light	Heavier
Damage-rate impact	Low with right size	Low on fragile	Medium
Storage cost	Very low (flat film)	High (pre-inflated)	Medium to high

Putting it together

A true cost-per-parcel figure adds material, labor, added freight from weight, and the amortized cost of damage and returns, then subtracts the storage savings of a compact fill. Run that calculation and air pillows usually come out lowest for general void-fill, not because the roll is cheapest, but because they carry almost no weight, place fast, store flat, and protect well when sized correctly.

Choosing for your order

The lowest total cost usually comes from right-sized standard air pillows matched to your carton, with small parcel air pillows for mailers and large void-fill pillows for big cartons so you are not overfilling.
