15ml 30ml 50ml Plastic PP Round Bottles for Lotion Serum Cream
Engineered PP cosmetic bottles designed to protect active skincare formulations, reduce contamination risk, and support full OEM customization for global brands.
Structure & Working Principle
The bottle system consists of a PP container, dip tube, pump head, and sealing mechanism. When the pump is pressed, internal pressure forces liquid upward through the dip tube while preventing backflow through a one-way valve system.
- Dip tube ensures consistent product extraction
- Pump chamber controls dosage output
- Sealing ring prevents leakage and air ingress
- Return spring resets system after each use
