CUSTOM PET PREFORM DEVELOPMENT
We understand that standard sizes don't cover every packaging design. Our OEM/ODM services offer complete flexibility to bring your unique bottle concepts to life.
- Color Customization: Masterbatch coloring (transparent, amber, green, blue, yellow, white, or Pantone matched). Colors are distributed evenly during injection, ensuring a flawless finish on the final blown bottle.
- Size Customization: Adjust preform length, thread height, and inner diameter according to your target bottle volume and blow ratio requirements.
- Mold Customization: Our professional design team develops multi-cavity molds for exclusive neck finishes, unique thread geometries, and non-standard weights.
- Outer Packaging Customization: Customized carton printing, private labeling, and warehouse-ready pallet configurations to simplify your inventory management (e.g., customizing customer information and specifications on the carton).
MANUFACTURING TECHNOLOGY
We utilize the highly efficient Injection Stretch Blow Molding (ISBM) two-stage process, ensuring maximum precision and material integrity.
- Injection Molding: High-quality, food-grade virgin PET resin is melted and injected into precision molds. The final neck finish, thread, and inner diameter are formed here to exact tolerances (±0.1mm).
- Stretch Blow Molding (at your facility): The preforms are reheated and blown into the final bottle shape. Because the neck dimensions are already locked, the process guarantees consistent wall thickness, high clarity, and excellent top-load strength.
- Quality Control: Equipped with advanced inspection equipment, our factory monitors every production stage to ensure the preforms are free from defects, black spots, or deformation.
WEIGHT & BOTTLE CAPACITY
Selecting the right preform weight is crucial for balancing bottle stiffness, cost, and volume. The table below serves as a reference for cosmetic, hand sanitizer, and detergent bottles.
| Preform Weight Reference | Blown Bottle Capacity | Recommended Applications |
|---|
| 8g - 12g | 60ml - 100ml | Travel-size hand sanitizers, serums, sample lotions. |
| 14g - 20g | 200ml - 250ml | Standard lotions, body wash, hand soap. |
| 24g - 32g | 500ml | Family-size shampoo, conditioner, detergents. |
