Case Study: Large European Restaurant Chain — OEM Custom Leak‑Resistant Compartment PP Containers

2026-09-30

Client Background：

A major European quick‑service restaurant chain with hundreds of physical outlets. Their former third‑party containers suffered two major pain points: liquid leakage during delivery and warping after microwave reheating, leading to frequent consumer complaints. The client needed EU‑compliant multi‑compartment PP meal‑prep containers with custom OEM logo printing.

Project Challenges：

1. Multi‑compartment layout combined with reliable snap‑lock sealing to prevent soup‑leakage during delivery;
2. Material performance covering freezer storage and microwave reheating;
3. Small‑batch sample validation followed by fast ramp‑up for mass‑volume stable supply.

Primax (Pacneer) Solution：

1. Our engineering team optimized snap‑lock mold structures and adopted high‑impact food‑grade PP material to improve leak‑proof and heat‑resistant performance;
2. Produced OEM custom‑printed samples matching client brand‑VI for real‑store field testing;
3. Deployed automated injection‑molding lines for mass‑production with full‑process QA/QC random inspection to guarantee batch consistency;
4. Provided full container loading suggestions and sea‑freight support via Ningbo Port.

Project Results：

Long‑term cooperation started after sample approval. The first order exceeded 3 million sets of compartment containers. Customized boxes greatly reduced leakage‑related complaints. Repeat bulk orders are placed annually, making this client one of our stable European partners.
