Common Mistakes When Choosing a Supplier

• Choosing the cheapest supplier without testing quality
• Ignoring sealing structure (leading to leakage issues)
• No consistency in production
• Poor communication and slow response

These problems often appear after you start selling — when it is already too late.

Key Factors to Evaluate a Cooler Bag Supplier

• ✔ Product structure (not just appearance)
• ✔ Leakproof performance
• ✔ Material quality (TPU, welding process)
• ✔ Production capacity
• ✔ OEM / customization capability

Always test real samples before placing bulk orders.

Why Product Design Matters More Than Price

A cheaper product may look similar, but small design differences can create big problems.
