Client Background
A high-end food ingredients company in Italy required spice jars factory solutions for a new range of handmade spice products that would be available in the supermarket, at specialty retailers and online outlets. The company was looking for packaging that would help present the product and preserve its freshness over an extended period.
As a professional spice jars factory, Minghanggroup customized the glass spice jar with a square body, a wide-mouth opening, a transparent glass structure and a natural bamboo lid with an inner sealing layer for the client.
The square design was chosen as it would produce a modern shelf look and it would be easier to pack the cartons than the traditional round jars. With spices, the wide opening enhanced the user experience during measurement and the bamboo lid conveyed a natural touch that coordinated with the client’s high-end presentation of their food products.
The client chose Minghanggroup due to our direct production ability, customization ability, stable production quality and the experience in creating glass packaging solutions for food application.

Challenge
- Maintaining product freshness during storage and transportation: The client faced packaging problems, in the past, the containers were not providing the sealing solution. Powered ingredients were affected by moisture in both the texture and aroma, particularly in long distance transportation and storage in the warehouse.
- Develop premium look while keeping low production costs: The client desired a package that would be eye-catching on the store shelves, but also have very competitive unit costs for high volume distribution. Other suppliers offered some custom-made packaging which had to be created using a costly mold or complex finishing, which were not feasible for regular production.
Solution
Minghanggroup designed an optimized package solution with both functions and commerciality in mind.
- Optimized jar neck structure to provide enhanced compatibility of sealing components
- Reduced glass thickness for enhanced durability, while maintaining manufacturing cost-effectiveness
- Suggested a straight forward square mould design that added a high quality look without being overly complicated to produce
- Introduced new quality checks on lid fitting, glass clarity, and jar dimensions
- Provided development of export packing solutions to minimize damage potential on transit
Result
The tailored spice jars fulfilled the client’s requirements for looks and practicality. The enhanced sealing capacity ensured the freshness of spices, and the streamlined design minimized packaging expenses for bulk orders.
The Italian food manufacturer received the first order, and went on to develop a range of products with further customised jar sizes. From then on, Minghanggroup entered into a long-term partnership with them as their spice jars factory, where they can develop packaging for future use and supply wholesale.

How We Did It
Design Consultation
First of all, we studied the product positioning, prospective customers and retail space of the client. These requirements led us to suggest a square glass jar design, which would be visually attractive, efficient for storage and transport.
Engineering Review
Our engineering team assessed the structure of the jar, the thickness of the glass, the compatibility of the lid, and the feasibility for production. Modifications were made to make it possible for the design to be reproduced and manufactured in a large quantity.
Sampling
We made samples to test before we went into bulk production. The client was shown the shape of the jar, how it seals, its look and usability before finalizing the prototype.
