PET lids improve product visibility for retail display, supermarket ready meals, deli counters, and grab-and-go meal bowls. The 170mm lid system fits 750ml, 1000ml, 1200ml, and 1400ml square bowls, while the smaller 130mm lids fit the 500ml and 650ml range. Bioleader® can match lid type by rim diameter, packing plan, artwork needs, and destination market requirements.

Common matching choices include PP flat lids, PET dome lids, and paper lids. The final lid choice should match bowl size, product display needs, delivery method, and customer preference — TOF analysis. Bioleader® can help buyers match the right lid configuration for each size range from 500ml to 1300ml.
