Case Study: Custom Jam Jars for Canning for a Chile Client

Client Background

A Chilean food producer specializing in preserved fruit needed high-quality jam jars for canning to strengthen its domestic and export markets. After sourcing glass honey jars from Minghang, they returned to us for a customized glass packaging solution.

Our Challenge

The customer faced challenges with delicate glass, poor seal cap, and incompatible sizes, leading to product malfunction, shipping loss and labeling difficulties. They also needed a variety of jam jars for canning in different sizes to meet the needs of retail and wholesale customers, but had not found a reliable custom supplier.

Problem Analysis

We identified three major issues: insufficient durability of jam jars, inability to ensure a tight seal with cap, and limited packaging options. These shortcomings threatened product quality, shelf appeal and brand reputation. The client required reliable, flexible jam jars that balanced safety with aesthetics.
