Define the base-and-lid family first
Before ordering a multi-SKU program, identify exactly which bases are approved with which lids, under which service condition, and which combinations require separate testing. Similar capacity, shape or material is not proof that lids can be mixed.
Record the base family, exact approved lid or lids, intended food and handling condition, exceptions and the sample result that justifies each pairing.
Sample exceptions and control substitutions
Sample combinations that create a new closure relationship or service condition: smaller, deeper, divided or specialty formats; new lid styles; changed base shapes; or different carrying and stacking conditions.
The final lid-family map should label every pairing approved, sample-required or not permitted as a substitute. If an alternative does not belong to an approved family, treat it as a new pairing. Related: the rim-first cup program and packaging sample approval.
