What Are 28mm PET Preforms
Used For?
The 28mm neck finish is the global industry standard for still water, carbonated beverages, and juices. If your product uses a screw-cap bottle, there's a very high chance this is exactly what you need.
Still & Mineral Water
The 28mm PET preform with PCO 1881 neck finish is the global standard for still water, carbonated beverages, juices, and other screw-cap bottles. If your production line uses 28mm neck bottles, this preform is likely a perfect fit.
Carbonated Soft Drinks
Our 28mm preforms handle high CO₂ pressure with precision wall thickness -- ideal for CSD, sparkling water, and energy drink producers.
Juice, Tea & Flavored Drinks
FDA-compliant materials and food-grade PET resin ensure your juice, RTD tea, or flavored water meets global safety standards without compromise.
Edible Oil & Condiments
28mm preforms also serve edible oil, vinegar, soy sauce, and condiment bottles -- offering excellent chemical resistance and barrier properties.

Choosing the Right 28mm Neck Pet Preform
Not all 28mm PET preforms use the same cap system. Selecting PCO 1810 or PCO 1881 correctly is critical to prevent sealing failures, mold mismatch, or production downtime.
PCO 1810
The original 28mm neck finish with taller neck height and heavier wall profile, designed for older caps and legacy bottle filling systems.
- Neck diameter: 28mm
- Longer neck height -- heavier profile
- Compatible with legacy cap systems
- Ideal for older blowing machines
PCO 1881
Next-generation 28mm neck finish. Shorter, lighter neck profile reduces resin per preform and improves cost efficiency. Widely adopted by global beverage brands pursuing sustainability and efficiency.
- Neck diameter: 28mm
- Shorter neck height -- lighter profile
- Reduces material cost per unit
- Supported by modern blowing machines

Same 28mm Diameter. Different Cap System. Different Outcome.
Even with the same 28mm diameter, a wrong neck finish can compromise your line. Our technical team reviews cap type, bottle design, filling method, and blowing machine to ensure a perfect match — something standard trading companies rarely provide.

Engineered for Every
Beverage Application
Our PET preforms are precisely matched to the performance demands of each beverage category -- not a generic fit, but a purpose-built solution for your production line.
Bottled Water
Water brands require crystal-clear PET preforms with minimal acetaldehyde (AA) to preserve taste neutrality. Low-AA resin and lightweight wall design reduce material cost without compromising strength.
| Focus Area | Our Specification |
|---|---|

| Pressure Resistance | Rated for CSD filling up to 4.5 vol CO₂ |
| Neck Finish | Stable thread geometry, zero deformation |
| Sealing Integrity | 100% leak-tested, airtight cap interface |

28mm PET Preform
Buyer's Guide
AAnswers to common sourcing questions about 28mm PET preforms, PCO 1810 / PCO 1881 neck finishes, customization, MOQ, and quotation requirements.
Q1
What is the difference between 28mm PCO 1810 and PCO 1881 PET preforms?
PCO 1810 features a longer neck design with a higher thread profile, while PCO 1881 is a shorter, lighter neck finish -- typically saving 1-2g per cap. The right choice depends on your existing cap supplier, bottle mold dimensions, and filling line configuration. We recommend confirming your cap spec before placing a preform order.
Q2
Can you customize the weight of 28mm PET preforms?
Yes. Preform weight directly affects wall thickness, drop resistance, and material cost. We engineer the weight based on your target bottle capacity, bottle shape, and required structural strength. Lighter preforms reduce material cost but require careful optimization -- our engineering team will recommend the right spec for your application.
Q3
Are your 28mm PET preforms food grade?
Yes. Our 28mm PET preforms are manufactured using food-grade virgin PET resin as the standard material, suitable for water, carbonated beverages, juice, and other food-contact applications. All materials comply with FDA and REACH standards. Certification documentation is available upon request.
Q4
What is the MOQ for 28mm PET preforms?
Our MOQ is 10,000 pcs per SKU. Bulk orders are strongly recommended for better unit economics and consolidated shipping efficiency. Higher volumes unlock better pricing tiers and priority production scheduling -- contact us to discuss volume-based pricing for your sourcing plan.
Q5
Can I choose custom colors for my preforms?
Yes. We support a full range of custom colors to match your brand identity. Standard options include clear, light blue, green, amber, and white. Pantone-matched or RAL-referenced custom colors are also available based on your order volume and masterbatch requirements.
Q6
What information do you need before providing a quote?
To generate an accurate, practical quote we need the following details upfront. Missing information typically delays the process by 1-2 business days.
- Neck finish -- PCO 1810 or PCO 1881
- Preform weight -- in grams (or target bottle volume)
- Color -- clear, custom, or Pantone reference
- Order quantity -- total pcs per shipment or annually
- Bottle application -- water, CSD, juice, hot-fill, etc.
- Destination port -- for accurate freight and lead time estimate
