| Project | Typical parameters |
| Capacity | 30ml (The actual capacity should be reserved with a 5%-10% margin to prevent overflow)
|
| Material | PET (transparent/white), HDPE (semi-transparent/ opaque) |
| Bottle mouth diameter | 18mm, 20mm, 24mm (suitable for the caps of common health supplements) |
| Height of the bottle | Approximately 70mm - 90mm (depending on the design of the bottle) |
| Bottle diameter | Approximately 35mm - 45mm |
| Wall thickness | 0.8mm - 1.2mm (ensure pressure resistance and sealing performance) |
1. Material Selection PET
Advantages: High transparency, resistant to acids and alkalis, antioxidant properties, suitable for liquid enzymes (displaying the contents).
Certification: Must comply with FDA or EU 10/2011 food contact grade standards. HDPE
Advantages: Low cost, shock-resistant, suitable for enzymes that need to be stored in a dark environment (such as those containing photosensitive components).
2. Bottle Cap Accessories
Child Safety Cap: Must comply with CPSC certification (for the US market).
Tamper-Resistant Cap: Aluminum foil inner liner or anti-theft ring design (enhances sealing performance).
Dropper Cap: Suitable for precise use of liquid enzymes (needs to be customized separately).
3. Special Process Requirements
Process Explanation
Screen printing/Stamping: Printing of brand logo and ingredient list (resistant to friction)
Relief/Embossing: Enhancing the texture of the bottle body (higher mold cost)
Ultraviolet protection treatment: Adding UV barrier agent to protect photosensitive components
Sterile filling compatibility: The bottle mouth needs to meet the requirements of the automated filling production line
