How are Pulpex bottles manufactured?
Pulpex bottles are produced using a multi-patented wet-moulding process. Fibre is formed into single-piece containers, dried, and then internally coated with a proprietary food-grade barrier that is designed to be compatible with both the product inside and the paper recycling chain.
How long does a Pulpex bottle take to make?
The full process takes around one hour per bottle, from starting fibre material through to a finished decorated bottle.
How can Pulpex produce bottles at scale?
Pulpex bottles are manufactured in parallel, with many bottles processed at the same time.
What kind of fibre is used?
Pulpex bottles are made using materials from well-managed, FSC®-certified forests and other controlled sources and/or sustainably sourced wood that is PEFC-certified. Pulpex holds both FSC® and PEFC Chain of Custody certifications.
How are the bottles coated?
The coating is an ultra-thin layer of water-based polymer dispersion chemistry. Pulpex also uses vapour deposition layers that can leave a golden shine on the inside of the bottle.
Other FAQ's

Why do we need a paper bottle? Glass is great, and recyclable too.
At Pulpex, we believe consumers should decide what type of bottle they prefer to use. Glass bottles are created using a lot of energy (which can create CO2 emissions) and recycling glass also takes a lot of energy. Many glass bottles are not recycled, especially in geographies with poor recycling infrastructure. Glass bottles that aren't recycled can last hundreds of years in the natural environment and if broken can create a safety hazard to humans and animals.
What are the technical specifications?
Technical specifications for three of our typical bottle shapes can be found here. When bottle manufacturers begin to roll-out the technology, information packs on how to work with Pulpex for your packaging design will be more broadly available.
