The design and construction of PreLog make it Europe’s leading returnable container. PreLog is an efficient, hygienic distribution tool for either manual or automated handling. PreLog has a minimum of recesses outside and inside, making it easy to wash and keep clean. Smooth walls and base protect the contents, whilst perforated sides ensure a good air flow to promote produce freshness. The upper rim is manufactured by using gas-assisted injection moulding or designed with reinforcement ribs. This gives a strong, rigid container with the lowest possible weight.
