Frequently asked questions

What plastic are water bottles made of?

European still and sparkling water bottles are made of PET (polyethylene terephthalate). PET is light, transparent, mechanically strong enough for thin-wall blow-moulded bottles, and recyclable through deposit-and-return schemes. From 2025, all PET beverage bottles sold in the EU must contain at least 25% recycled content, rising to 30% in 2030 under PPWR.

Is PET plastic safe to drink from?

Yes. PET is approved for direct food and beverage contact under EU 10/2011 and FDA 21 CFR 177.1630. It does not contain BPA. Acetaldehyde levels in modern bottle-grade PET are below the threshold that would affect water taste — typically under 6 μg/kg in finished bottles. PET is the most widely used plastic for beverage packaging globally.

What plastic is used for milk bottles?

Most European milk and dairy bottles are extrusion blow-moulded HDPE (high-density polyethylene), typically pigmented white with TiO₂ to protect light-sensitive vitamins. HDPE is food-contact compliant, robust through cold-chain handling, and recyclable into dairy-bottle-to-dairy-bottle closed loops in countries with deposit-and-return infrastructure.

Why are some plastic bottles green or blue?

Coloured PET (green for sparkling water, blue for some still waters) uses pigments added at the resin or master-batch stage. Coloured PET is recyclable but sorts into a separate recyclate stream that commands a lower price than clear PET. Several major brands have moved to clear PET to maximise rPET recovery and meet recycled-content targets.
