Zerolys has unveiled a biomaterial, Phyber, made from engineered plant fibres and intended for rigid packaging such as bottles, tubes and jars used in consumer-packaged goods.
The formulation avoids fossil-derived plastics and bioplastics, and does not contain microplastics, petrochemicals, PFAS, BPA, and phthalates.

Phyber’s fibre base is described as using agricultural residues, with a natural wax layer included to provide barrier properties linked to shelf-life requirements.
Phyber containers are designed to work on conventional filling lines and with existing caps and closures, depending on the product being packed.
The material is biodegradable and intended to decompose in natural conditions after disposal.
The stated application areas include food and drink, home care and personal care.
Zerolys said it has produced working prototypes across different sizes, forms and colours, and that the project is moving from lab development to pilot-scale output.
For liquids and semi-liquids, Zerolys uses a proprietary plant-based internal coating to reach barrier performance levels needed to protect contents.
The company added that containers can be adapted in shape, colour and embossing.
Late last year, Cove Packaging introduced a fibre-based bottle format that the company said may lower carbon emissions.
Separately, in January this year, Sabert launched the PULP Ultra food packaging range, made largely from bagasse fibres, across Europe, the UK, and Ireland. The company marketed the products as having the ability to offer grease resistance without using “forever chemicals”.
