PPWR void-space limit breached: what too much air in the box costs
The EU Packaging Regulation (PPWR) caps empty space in grouped, transport and e-commerce packaging at 40%. Anyone permanently using oversized boxes risks — once the transition periods end — the packaging being deemed non-compliant, meaning it may no longer be placed on the market.
Beyond the regulatory side, the void-space limit has an immediate commercial effect: every centimetre of air in the box costs postage, filling material and higher dual-system licensing fees. Large boxes also increase returns and transport damage.
Those who document the void-space ratio and match their box sizes to the product range can demonstrate, in the event of a check, that the packaging is minimised to the necessary size. The void-space calculator provides this calculation together with an audit PDF.
The sanctions you are facing
In transport, grouped and e-commerce packaging the empty space may not exceed 40% — at least 60% of the volume must be used.
Packaging that fails the PPWR requirements may not be placed on the market; market surveillance can prohibit distribution.
Oversized boxes drive higher shipping costs, more filling material, and higher dual-system licensing fees.

How much void space does the PPWR allow?
In grouped, transport and e-commerce packaging the empty space may not exceed 40% — at least 60% of the box volume must be used by the product and any necessary protective material.
What happens with too much void space?
After the transition periods, packaging with more than 40% empty space is deemed non-compliant and may not be placed on the market. Market surveillance can prohibit distribution; on top come unnecessary shipping and material costs.
How do I prove compliance?
Calculate the void-space ratio for each box–product combination and document the result. The PPWR void-space calculator produces an audit PDF with the calculation, timestamp and result for your compliance records.
