PET preform questions, answered.
A quick guide to Nawkiran product families, which preform suits water and edible oil bottles, supply across East India, capacity, locations, rPET-ready packaging, and WhatsApp enquiries.
What types of PET preforms does Nawkiran manufacture?
Nawkiran manufactures 3-Start/Alaska, PCO 1810, PCO 1881, jar, fridge-bottle, and ROPP preforms. Available neck finishes run from 22 mm to 120 mm across the catalogue, with weights set out on each product page.
Which preform is used for packaged drinking water bottles?
Nawkiran's 3 Start/Alaska preforms are made for packaged drinking water bottles. They come in the 26/22 mm and 28 mm neck finishes, weighing 7.1–33.1 g, 18 neck and weight variants in all. Choose the neck finish and weight that match your bottle and cap, then send your enquiry on WhatsApp.
Which preform suits edible oil bottles?
ROPP preforms suit edible oil bottles: the neck is made for an aluminium roll-on pilfer-proof cap, which gives a tamper-evident seal. Nawkiran makes them in the 25 mm and 28 mm neck finishes, weighing 10.5–30 g, 8 neck and weight variants in all.
What is the difference between PCO 1810 and PCO 1881?
Both are 28 mm carbonated-drink neck finishes. PCO 1881 is the shorter, lighter finish and PCO 1810 the taller one, and their caps are not interchangeable, so pick the finish your cap and filling line already use. Nawkiran makes both; the PCO 1810 vs PCO 1881 guide sets them side by side.
Which jar preform neck sizes do you make?
Nawkiran makes jar preforms in 7 neck sizes: 38, 48, 53, 63, 83, 96 and 120 mm, weighing 5.5–101.5 g across 28 neck and weight variants. Each neck size lists its own weights on the jar preforms page.
Do you make coloured PET preforms?
Yes. Nawkiran has supplied clear (natural) preforms and tinted preforms in green, blue, pink, yellow, violet, amber, orange and red. Name the colour along with the family, neck finish and weight when you enquire on WhatsApp.
Do you make hot-fill PET preforms?
Nawkiran has made hot-fill versions of some preforms. Ask when you enquire.
Do you supply PET preforms outside West Bengal?
Yes. Nawkiran supplies buyers in West Bengal, Jharkhand, Odisha, Bihar, Assam, Nagaland, Tripura and Mizoram. See PET preforms across East India for the regions, then send the family, neck finish, weight and order quantity you need on WhatsApp.
Can Nawkiran help us evaluate rPET?
Yes. Nawkiran is developing rPET-ready options for customers who want to reduce virgin-resin use. rPET can reduce virgin material exposure and may lower material cost when the right grade is available at a favorable price; final performance, compliance, colour, and pricing depend on the application and resin mix.
What is the monthly PET preform capacity?
Nawkiran operates 11 preform machines with a stated monthly capacity of over 400 tonnes across 75+ product types.
Where are the office and manufacturing plant?
The registered office is at Poddar Court, 18 Rabindra Sarani, Kolkata 700001. The manufacturing plant is at Balaji Complex on Old Delhi Road in Baidyabati, West Bengal.
