From Preform to Finished Bottle
How it works
Frequently Asked Questions
Both are 28mm neck finishes, but the PCO 1810 has a taller neck profile compared to the PCO 1881. The 1810 is an older standard commonly used for larger bottles — typically 1 litre and above. The 1881 is a lighter, shorter neck designed to reduce plastic use on smaller bottles. Caps and closures are not interchangeable between the two, so it is important to confirm which standard your capping machine and caps are built for.
As a general guide — 17g–22g preforms are typically used for 1 litre bottles. 24g–32g suits 1.5 to 2 litre formats. 37g–50g is for larger containers (2 litres and above). Final bottle dimensions also depend on your mould design, so it is best to discuss your requirement with us before confirming an order.
