Case Study: Glass Lunch Boxes for a French Food Service Client

Client Background​

Our customer is a Paris-based food service provider, specializing in premiums, ready-to-Eat food (eg, quint, salad) for corporate offices and Upskale Cafe. With a strong commitment to stability and zero plastic waste, he sought to align with French eco-law and to replace disposable containers with durable, reusable glass lunch box to enhance the brand image.

Our Challenges​

When reaching out to Minghang, they faced 3 key hurdles:

• Need for shatterproof glass (critical for office transport).
• Custom compartment designs (to separate meals/sauces).
• Compliance with French food-contact safety standards (AFNOR NF D10-300) that their prior supplier couldn’t meet.​

Problem Analysis​

Our team identified core pain points: Standard glass lunch boxes lacked durability, leading to high breakage; generic compartments failed to fit the client’s meal portions; and subpar glass violated safety rules, risking product recalls. The priority was balancing durability, customization, and compliance for glass lunch boxes.​

Solutions​

We addressed challenges with tailored actions: Used tempered borosilicate glass for shatter resistance, Designed 3-compartment molds (custom to the client’s portion sizes) with leakproof silicone lids, Conducted AFNOR certification testing in-house, ensuring full compliance.​
