How PLA Water Bottles
Are Actually Made

Most brands describe their sustainability at the marketing level. We publish the full production chain instead. this page walks through every step from a sugarcane field to a sealed 500 ml PLA bottle leaving our Ahmedabad line, along with the checks and certifications at each stage.

Production Chain

Eight Steps from Field to Finished Bottle

The upstream steps happen at accredited PLA resin suppliers. The downstream steps happen inside our own facility.

Plant Sugar Cultivation

Corn, sugarcane, or cassava grown on existing agricultural land captures atmospheric CO₂ during growth.

Sugar Fermentation to Lactic Acid

Plant sugars are fermented by lactic acid bacteria to produce food-grade lactic acid at the resin supplier.

Lactic Acid to Lactide

Lactic acid is dehydrated and cyclised into lactide, the ring-shaped monomer used for PLA polymerisation.

Polymerisation to PLA Resin

Lactide is polymerised with a catalyst into food-grade PLA resin, delivered to us as clear pellets with a lot-level certificate of analysis.

Resin Drying & Dehumidification

On our line, PLA pellets are dried to below 250 ppm moisture. essential for keeping the polymer clear and strong through injection.

Injection Preforming

Dried pellets are injection-moulded at 190–210 °C into amorphous preforms sized for each bottle format.

Stretch-Blow Moulding

Preforms are heated to 85–95 °C and stretch-blown against the final bottle mould, producing a crystal-clear PLA bottle with uniform wall thickness.

Filling, Capping & QC

Under HEPA-clean conditions, bottles are filled with 10-stage purified water, sealed with a bio-HDPE cap, labelled, and quality-checked before palletising.

In the Factory

Injection Preforming and Stretch-Blow Moulding

PLA behaves differently from PET on a bottling line. The glass transition temperature is lower (around 60 °C versus 75 °C), the melt is more shear-sensitive, and the crystallisation kinetics force us to run the preform stage at tighter dwell tolerances.

We dry the PLA resin to below 250 ppm moisture, injection-mould amorphous preforms at 190–210 °C, and then stretch-blow them at 85–95 °C into finished bottles. The result is a crystal-clear PLA bottle with uniform wall thickness and no residual stress. structurally as sound as the equivalent PET part.

Every fifth bottle is pulled for wall-thickness verification. Every hour a full-batch drop, top-load, and burst test is run. Rejected bottles are ground and returned to a certified PLA recovery partner. nothing goes to landfill.

The Water Inside

10-Stage Purification Before Filling

A biodegradable bottle around low-quality water misses the point. Our water side of the line is BIS/ISI certified to IS 14543.

🧫

Stages 1–3: Sediment & Carbon

Raw water passes through a 5-micron sediment filter, then activated carbon for chlorine and organic contaminant removal, then a 1-micron polishing filter.

💠

Stages 4–6: RO & Remineralisation

Reverse osmosis at 200 psi strips dissolved solids to below 15 ppm. A controlled remineralisation stage adds back magnesium and calcium for taste and BIS compliance.

☀️

Stages 7–10: UV, Ozone & Storage

UV sterilisation, ozonation, a final 0.2-micron microbiological filter, and a sanitised stainless-steel storage tank hold water ready for filling under HEPA-clean conditions.

Quality & Compliance

What Every Batch Is Tested For

🧪

Bottle Material

PLA resin certificate of analysis per lot, IS/ISO 17088 compostability, food-contact migration testing under IS 9845, and heavy-metals screening.

💧

Water Purity

Total dissolved solids, pH, alkalinity, hardness, chlorides, sulphates, and full microbiological panel to IS 14543 packaged drinking water spec.

📋

Filled Bottle

Fill volume, cap torque, seal integrity leak test, drop test, and label-adhesion check on every production run.
