Petainer PET bottles are designed with a variety of neck finishes and closures to ensure compatibility with different dispensing systems. Our bottles offer secure sealing, easy pouring, and maintain product integrity across various applications.
28mm BPF: Neck finish for beverage bottles requiring reliable sealing and compatibility with standard screw caps.
28mm PCO 1810: Lightweight finish developed for carbonated soft drinks and water, reducing material use while maintaining pressure resistance.
28mm PCO 1881: Global standard for CSD bottles, enabling further lightweighting and improved sustainability performance.
38mm DBJ: Suitable for juice, dairy, and functional beverages, supporting tamper-evident closures and wider pouring.
38mm SP400: Multi-purpose neck finish for beverages, food, and household liquids, compatible with screw caps.
26/22 GME: Designed for water and carbonated soft drinks, compatible with lightweight tethered closures for improved circularity.
BVS 30H60: Designed for spirits and wine bottles, compatible with tamper-evident aluminium closures.
Easton: Specialist neck finish for hot-fill applications, providing enhanced sealing and thermal resistance for products like sauces and ready meals.
Crown Cork: Used for beer and carbonated beverages requiring metal crown caps and strong carbonation retention.

Petainer worked with German Wells Cooperative (GDB) to move reusable PET bottles to 30% rPET in the German market. The project strengthened an established returnable system, reduced bottle carbon footprint, and showed how recycled content can be introduced at scale without moving away from a proven refill model.
Soda bottles use high-viscosity PET and specific wall thicknesses to provide a superior CO2 barrier, preventing gas from escaping and keeping drinks fizzy for 6–9 months.
This "petaloid" design allows the bottle to withstand high internal pressure from carbonation without deforming or bursting, even during temperature fluctuations.
Most PET CSD (Carbonated Soft Drink) bottles are designed to withstand internal pressures up to 7 bar (approx. 100 PSI) before failure.
Yes, PET grades for soda are engineered for Environmental Stress Crack Resistance (ESCR) to prevent failure when exposed to carbonation and conveyor lubricants.
Yes, food-grade rPET is suitable for CSDs. Manufacturers often use blends of 25%, 50%, or 100% rPET while maintaining the required pressure-bearing integrity.
Yes, most soda caps are made of HDPE or PP, which are widely recyclable alongside the PET bottle in modern municipal streams.
The most common neck finish for CSD is the PCO 1881 or PCO 1810, designed specifically for high-pressure carbonation and tamper-evident closures.
