A mixed-SKU MOQ is not one minimum divided among widths. Film, conversion, cores, cutter boxes, artwork and cartons can each have their own minimum or setup. Map those layers before asking to combine 300 mm and 450 mm.
Use this component matrix
| Layer | Shared? | Supplier answer required |
|---|---|---|
| Film construction | [yes/no] | Material, formula, thickness and production run |
| Conversion | Usually by SKU | Minimum for each width, length and core |
| Printed pack | Usually version-specific | Minimum per dieline/artwork |
| Master carton | [yes/no] | Count, dimensions, label and layout |
Expose leftover-component risk
Ask who pays for unused printed boxes, labels or cores, how long they are stored and what happens after an artwork/specification change. A low finished-roll MOQ can hide a larger packaging commitment.
Allocate from demand
Do not split quantity equally unless demand is equal. Calculate coverage by SKU, then round to production and carton multiples. Approve and inspect every SKU separately. The MOQ guide explains one-SKU drivers; YIYUAN’s commercial range supplies the candidate widths and formats for the matrix.
