How it works
Frequently Asked Questions
CTC stands for the cap and closure type standard. The "29" refers to the outer thread diameter in millimetres and "21" refers to the inner opening diameter. This wider inner opening makes the CTC 29/21 neck the preferred choice for oils, sauces, and other pourable food products where a larger flow opening is needed. Caps for this finish are widely available in India.
The 16g preform is typically used for smaller bottles in the 200ml to 500ml range. The 23g and 26g variants suit 500ml to 1 litre containers.
