Standards, assumptions & data sources

PackMize separates published reference data, planning defaults and calculated outputs so a preset is never mistaken for a universal physical specification.

Machine-readable sources Methodology

Source policy

PackMize uses primary standards, equipment manufacturers or recognized industry references where they materially improve a planning assumption. External sources document the reference dimension or industry context; the PackMize engine then calculates from the explicit numeric inputs shown to the user.

Operational rule: presets are planning profiles. For an actual load, cut plan or shipment, use the dimensions, weight limits and machine constraints from the equipment and material you will physically use.

Reference hierarchy

01Published reference

Standards body, pallet association, carrier or recognized industry research.

02PackMize assumption

A transparent preset or worked-example input, labelled as a planning value where it is not universal.

03Deterministic result

The engine output, version and optimality status are reported separately from the source data.

Pallet references

European Pallet Association (EPAL) — Euro pallet datasheet — used for the EUR / EPAL 1 dimensions, approximate tare and published safe working load represented by the EPAL planning preset.

ISO 6780:2003 — international reference for principal dimensions and tolerances of flat pallets. PackMize links it for dimensional standards context rather than treating every regional pallet as interchangeable.

Pallet Foundation market survey — industry research used to support the prominence of the 48 × 40 in pallet footprint in North America. PackMize does not treat one tare or payload rating as universal for every 48 × 40 pallet.

Container references

Hapag-Lloyd — 20' Standard — representative inside, door and weight data. The carrier explicitly notes that equipment specifications vary by manufacturer.

Hapag-Lloyd — 40' Standard High Cube — a representative 40 ft High Cube profile used as an external comparison, not as a claim that every container matches the PackMize preset.

Why PackMize presets may not equal one source line-for-line

A container fleet can contain several manufacturing series with slightly different inside height, width, door dimensions, tare or payload. A pallet footprint can also be shared by different constructions and ratings. For that reason, PackMize presets are deliberately labelled as planning profiles and the calculators expose custom dimensions for operational use.

Calculated examples are versioned separately

Worked examples publish the application release and engine identifier. The current application is PackMize 3.7.4, while the core optimization family remains 3.6.0. Numeric outputs are deterministic for the stated inputs and engine version.
