Background
Being a glass milk bottle supplier in the professional market, Yeboda was approached by an Egyptian milk dairy brand that distributes fresh milk to supermarkets and cafes. The brand sought a good glass milk bottle supplier that would provide durable glasses bottles that can be refilled and transported in cold chain. They personalized round glass milk bottle with food grade flint glass, which had a wide mouth, strengthened base, thickened walls and could be used with twist-off metal tops. Our high-level engineering support, the ability to customize, and the history of enhancing the life span of glass bottles in dairy applications are the reasons why the client has selected Yeboda.
Challenges
High Breakage During Distribution
Bottles frequently cracked during warehouse stacking and truck transportation, causing product loss and rising replacement costs.
Low Glass Clarity
Hairline fractures appeared around the bottle mouth under capping pressure, interrupting automated filling operations.
Cause Analysis
Yeboda’s technical team conducted impact tests and stress analysis and identified the core problems:
- Uneven wall thickness created weak points at the shoulder and heel.
- Inadequate annealing left residual internal stress in the glass structure.
Solution
Structural Reinforcement
We redesigned the bottle profile with balanced thickness, strengthened the heel radius, and optimized base geometry for higher impact resistance.
Mold and Handling Optimization
Yeboda improved annealing parameters, introduced thickness monitoring, and upgraded carton dividers to better protect bottles during transport.
Results
Breakage rates dropped by over 65%, filling efficiency stabilized, and distribution losses were sharply reduced. The Egypt brand restored confidence in its packaging quality and established Yeboda as a long-term strategic glass milk bottle supplier partner.
