EnglishPET Preforms Wholesale: Pricing, Specs, and Bulk Buying Guide
PET preforms wholesale purchasing is the most cost-effective way for beverage, water, and packaging manufacturers to secure consistent raw materials at scale while maintaining control over bottle quality. By sourcing PET preforms in bulk, buyers reduce unit costs, stabilize supply chains, and ensure compatibility with their blow molding processes.
What PET Preforms Wholesale Means in Practice
PET preforms wholesale refers to buying injection-molded PET preforms in large quantities directly from manufacturers or authorized distributors. These preforms are later reheated and stretch-blown into bottles or containers of various sizes.
Wholesale orders typically start from tens of thousands of pieces per specification. For example, a standard 28mm neck, 18g water bottle preform is commonly ordered in lots of 100,000 units or more to achieve competitive pricing.
Common PET Preform Specifications Offered Wholesale
Wholesale suppliers usually provide a defined range of specifications rather than fully custom designs. Understanding these standards helps buyers match preforms to their bottle molds.
| Neck Finish | Weight Range | Typical Use |
|---|---|---|
| 28mm PCO | 14g–24g | Water, soft drinks |
| 30mm | 30g–60g | Edible oil, sauces |
| 38mm | 50g–120g | Juice, dairy, wide-mouth bottles |
Wholesale PET Preform Pricing Factors
PET preforms wholesale pricing is not fixed and depends on several measurable factors. Understanding these elements helps buyers negotiate more effectively.
- Preform weight: Pricing is usually calculated per kilogram; heavier preforms increase total cost.
- Raw PET resin index: Market PET resin prices directly affect wholesale quotations.
- Order volume: Orders above 500,000 units often receive 5–12% lower unit prices.
- Additives: UV blockers, colorants, or oxygen barriers increase material cost.
As a reference, bulk orders of clear water bottle preforms typically range between USD 1.20–1.60 per kg depending on resin conditions and region.
Quality Standards in PET Preforms Wholesale Supply
Wholesale buyers must prioritize quality consistency, as defects multiply quickly at scale. Reliable suppliers implement standardized inspection and testing protocols.
Key quality checkpoints
- Visual inspection for bubbles, black spots, or uneven walls
- Neck finish dimensional tolerance within ±0.05 mm
- IV (Intrinsic Viscosity) consistency for stable blowing performance
Minimum Order Quantities and Lead Times
PET preforms wholesale suppliers usually define MOQ based on mold cavity count and production efficiency. Understanding these limits avoids delays.
Standard MOQs range from 20,000 to 50,000 pieces per SKU, while customized colors or neck finishes may require higher volumes. Lead times typically fall between 10–20 days after deposit confirmation.
How to Choose a PET Preforms Wholesale Supplier
Selecting the right wholesale supplier directly impacts production stability and cost control.
- Verify production capacity and number of injection lines
- Request recent test reports or sample preforms
- Confirm resin brand and food-grade compliance
- Evaluate export packaging and logistics experience
Final Practical Takeaway
Buying PET preforms wholesale is not only about lower prices, but about securing consistent specifications, stable quality, and predictable lead times. Manufacturers who define their technical requirements clearly and work with experienced suppliers gain long-term cost and production advantages.
