Mid-2026 Container Teams Spec Void Fill with Stretch Wrap as One System

Mid-2026 container-loading RFQs on PackTrades are less willing to treat dunnage air bags and stretch wrap as unrelated consumables. Buyers want one pack-out sheet that shows void placement, fill checks, and wrap settings together.

Load planners say many damage claims start after a “tight wrap” is applied to a pallet that still has uncontrolled lateral voids at the door end or between uneven tiers.

Eltete-class transport packaging suppliers and peers report more requests for bag size charts tied to photographed voids, plus edge board notes where straps and wrap meet carton corners.

Stretch-film buyers are adding pre-stretch windows and tear photos to the same file, especially on sharp-corner export cartons that cut film before the container is sealed.

Factories and forwarders both benefit when inflation responsibility and wrap machine settings are written down: fewer on-site arguments about who left the load free to shift.

Why buyers care: a pallet can look well wrapped in the yard and still arrive with crushed print or leaned stacks if void fill and film settings were never validated as one system.

Buyer takeaways

Attach a void map, bag size list, and fill/dwell check to every container pack-out RFQ.

Freeze stretch-film gauge, pre-stretch, and wrap pattern on the same sheet as dunnage placement.

Require side/door-end photos of the approved loaded system before releasing mass shipments.
