Case Study: How a Glass Water Bottle Dealer Reduced Shipping Breakage for Canada Brands

Client Background

A Canadian glass water bottle dealer supplying bottles to several beverage startups was looking for a dependable glass water bottle factory to improve product durability during long-distance transportation. Their previous supplier had frequent breakage issues during pallet shipping across Canada. The client customized 550ml clear cylindrical glass water bottles with a slim neck, smooth straight body, and reinforced concave base. The bottles used a 28mm screw finish suitable for aluminum caps and reusable beverage lids. The dealer chose Minghang because of our stable forming technology, strict wall-thickness control, and experience in export-safe packaging design.

Challenge

High Breakage During Distribution

During warehouse transfers and truck transport, a portion of bottles cracked or chipped, especially near the base and shoulder areas.

Carton Instability on Pallets

Standard packaging cartons did not provide sufficient structural support, causing bottles to shift and collide during long-distance delivery.

Cause Analysis

After evaluating production samples and logistics conditions, our team identified two key problems:

• Uneven wall thickness distribution created structural stress points during impact.
• The existing carton divider design lacked enough rigidity to prevent bottle movement.

Solution

Improved Glass Distribution

We adjusted forming parameters and gob weight to ensure more uniform wall thickness and reinforced the shoulder and base areas for higher impact resistance.

Reinforced Export Packaging

Our packaging unit has redesigned the cartons using the thicker corrugated material and increased internal partitions to anchor each bottle in transit.

Transport Simulation Testing

Before mass production, we conducted drop tests and vibration simulations to verify that the improved packaging system could withstand long shipping routes.
