Why Material Selection Matters for Wholesale Baby Bottles
When sourcing baby bottles for retail, distribution, or private-label brands, material selection is one of the most important decisions. Parents today pay close attention to safety certifications, durability, and product lifespan, while importers and wholesalers must also consider pricing, shipping costs, and market positioning.
Among the most common options in the baby feeding industry, PPSU, Tritan, and PP are frequently compared. Understanding the differences can help bulk buyers choose the right product line and avoid costly sourcing mistakes.
This guide compares PPSU vs Tritan vs PP for baby feeding products, focusing on safety compliance, heat resistance, durability, and wholesale opportunities.
