69mm PET Oil & Wine Bottle Preform – Full Specifications & Customization
Detailed Product Description
Our 69mm PET bottle preforms are engineered to meet the demands of high-quality oil and wine packaging. Constructed from food-grade PET material, they offer exceptional clarity, durability, and chemical resistance. The precise 69mm outer diameter and 62mm inner diameter ensure compatibility with standard closures for a perfect, leak-proof seal. Ideal for large-volume containers (typically 3L to 5L+), these preforms are the reliable foundation for sturdy, premium bottles. Full customization of color and a complete range of neck finishes (27mm to 72mm) are available to match your specific brand and production requirements.
Enhanced Key Features & Benefits
Precision Engineering for Perfect Performance:
Consistent Dimensions: Manufactured with tight tolerances (±0.3mm), ensuring every preform fits seamlessly on blowing machines and with caps, reducing production downtime.
Superior Seal: The precisely molded neck and thread design guarantee an airtight and secure closure, preserving product freshness and preventing leakage during transport and storage.
Optimal Material Distribution: Designed for even stretching during the blow-molding process, resulting in finished bottles with consistent wall thickness, excellent clarity, and high burst pressure resistance.
Premium PET Material Properties:
Food-Safe & Compliant: Made from 100% virgin, food-grade PET resin. Compliant with international safety standards including FDA (US) and EU regulations for food contact materials.
High Clarity & Gloss: Offers brilliant transparency to showcase your product's color and purity, enhancing shelf appeal.
Lightweight & Strong: Provides an excellent strength-to-weight ratio, reducing shipping costs while ensuring durability.
Chemical Resistance: Inert to oils, alcohols, and most acids, ensuring the preform does not interact with or contaminate your product.
Complete Customization & Flexibility:
True Color Matching: We can match any Pantone color or sample you provide. Standard options include Clear, Light Blue, Green, and Amber (UV barrier for light-sensitive oils).
Comprehensive Size Range: Not just 69mm. We supply a full spectrum of neck finishes to support your entire product line, from small sampler sizes to large industrial containers.
Tailored Solutions: Our engineering team can work with you to adjust preform weight, length, and design to optimize performance for your specific bottle shape and blowing equipment.
Designed for Manufacturing Efficiency:
High Blow-Up Ratio: Engineered for stable processing, leading to high yields and lower per-bottle costs in your production.
Low Acetaldehyde (AA): For sensitive products like water and certain beverages, we offer low-AA material options upon request.
Clean Packaging: Preforms are packaged in clean, sealed bags or boxes to prevent dust contamination before use.
