When Does Void Fill Become Unnecessary?
Void fill protects products from movement inside a box. It cushions impact, reduces vibration, and prevents shifting during transit.
But in many shipments, void fill isn’t just unnecessary — it’s wasted material, added labor, and avoidable cost.
Here’s how to determine when you can safely eliminate it.
First: What Is Void Fill Actually Doing?
Void fill serves one primary purpose:
Prevent product movement inside a shipping container
If your product cannot move — or movement won’t cause damage — void fill may not be needed.
That decision depends on three variables:
Product durability
Packaging fit
Shipping environment
Let’s break those down.
When the Box Is Properly Sized
The most common reason void fill becomes unnecessary is simple:
The box is correctly sized for the product.
If there is less than ½–1 inch of open space around the product, movement is already minimized.
Oversized cartons create artificial void space. When you right-size the box, you often eliminate the need for filler entirely.

Right-sizing reduces:
Material costs
Dimensional weight charges
Labor time
Customer frustration with excess packaging
When the Product Is Structurally Durable
Some products simply do not require cushioning.
Examples include:
Dense metal components
Fully boxed inner retail cartons
Products already encased in rigid molded packaging
Heavy industrial parts with low fragility
If the product can withstand:
Drops
Vibration
Compression
Void fill may not add meaningful protection.
This is especially common in B2B industrial shipments, where product integrity is inherently high.
When You Use Custom-Fit Packaging
Custom corrugated inserts, partitions, or engineered cartons can eliminate the need for loose-fill materials entirely.
Instead of filling empty space, you design packaging that:
Locks the product in place
Distributes weight evenly
Prevents shifting structurally
This is common in:
Multi-item kits
High-value equipment
Repeat shipments with standardized SKUs

Engineered containment often replaces filler entirely.
When You’re Shipping via Pallet (Not Parcel)
Void fill is primarily a parcel-shipping concern.
If your cartons are:
Stretch wrapped
Strapped
Corner-boarded
Unitized on a pallet
Internal void fill becomes far less critical — especially for rigid or industrial goods.
Movement risk decreases significantly once loads are stabilized as a unit.

When Dimensional Weight Is a Bigger Risk Than Impact Damage
In some shipments, the larger cost risk isn’t product damage — it’s dimensional weight charges.
Excess box size increases freight cost dramatically.
In these situations, eliminating void space (and therefore filler) by downsizing cartons provides greater financial benefit than cushioning.

When Void Fill Is Still Necessary
Void fill remains critical when:
Products are fragile
There is significant empty space
Multiple items can collide
Parcel carriers handle shipments roughly
Vibration or drop risk is high

The goal isn’t to eliminate protection — it’s to eliminate unnecessary protection.
A Simple Test
Ask:
Can the product move inside the box?
If it moves, will that movement cause damage?
Is the box larger than it needs to be?
Is the product already structurally protected?
If the answer to those questions points toward low movement and low fragility, void fill may not be required.
The Strategic Approach
Smart packaging decisions focus on:
Engineering containment first
Right-sizing cartons second
Adding filler only when necessary
Void fill should solve a real problem — not compensate for poor box selection.
