Global Industrial Case Study
The Client: A national supermarket group standardising fresh-produce packaging across its regional depots.
The Challenge: Trays sourced region by region had drifted in wall thickness and colour, so presentation varied between stores and the packing lines could not run one film setting.
Our Solution: We consolidated the specification onto a single material and tolerance band, matched the colour across the whole size range and supplied trial pallets to each depot before the changeover date.
The Outcome: All depots now run one film setting, the presentation is uniform across the estate, and the customer has since added two further size ranges to the same programme.
B2B Frequently Asked Questions
Q1: Can lids or film be supplied matched to square self heating?
A: Lids, film and inserts are supplied as a matched set to the rim dimension, so the closure fits the container rather than being specified independently.
Q2: How do you handle quality claims on square self heating?
A: Claims are handled against the retained sample and the batch record. Send photographs and the batch code and we will confirm the disposition in writing.
Q3: What tooling investment applies to a custom square self heating?
A: Tooling is quoted against the cavity layout and gauge you need. Where an existing mould suits the specification there is no tooling charge at all.
