Close up of Smile Plastics' 'Marlais' material – a light blue recycled PET plastic surface material, with flecks of golden yellow and white.

Marlais

Made from: Plastic Packaging

Just like the thick, textural tangle of reeds and bulrush that lines our Welsh riverbanks, underlaid with weathered pebbles and sediment; Marlais gains its rich, patinated appearance from the mixture of materials that creates it. Offering a neutral combination of tones – blue with an organic grained aesthetic, Marlais makes a humble statement that’s ideal for commercial interiors.

We understand how important it is for your material choices to be just right – so we’ve introduced a customisation service. Just ask and we can make any small changes; for example, dialling up the blue or toning down the sandy flecks.

£18.00

Sample Size: 200mm x 200mm x 12mm

Made from: 100% recycled and 100% recyclable PET

Weighs: Up to 99kg – depending on panel size and thickness

Comes in: Supersized 3000 × 1200mm panels
Note: Panels may arrive slightly oversized by 1–5cm

Available in: 12mm and 20mm thicknesses as standard. Other thicknesses available on request.
Note: Thicknesses are nominal. Please allow for thermal expansion – up to 2mm per metre over a 10°C range.

We work hard to ensure our panels are as free from blemishes as possible, but by their nature, no two panels are the same. For us, every quirk, imperfection and mottle tells a different recycling story. Panels are supplied with a single-sided semi-matt finish as standard, and can also be supplied double-sided should your intended application require it. Please specify this when ordering.

We produce our Core materials in batches of 5-10 tonnes.

The ratio of colours and/or the exact colour may vary slightly between batches.

Pattern example images are for illustrative purposes only. We recommend purchasing a sample to experience the colour, pattern, and texture of the material.

Our panels are not available for direct purchase online. Pricing depends on material type, thickness, and quantity. Most stock items are dispatched within 5 working days of payment. Standard cutting, CNC and simple finishes are typically dispatched within 3 weeks, while more complex CNC work, fabrication, assembly and custom materials may take longer. If you have an urgent requirement, please contact us in advance — we’ll always do our best to help. We work across six pricing categories, so by speaking with us directly we can ensure you receive tailored guidance on the most suitable material for your project, along with accurate pricing and lead times. All sales are subject to Smile Materials’ standard terms and conditions.

Smile Plastics Fabrication Guidelines

From sourcing and sorting raw materials to forming panels and finishes, every step is carefully considered, and often done by hand. We work with a range of waste streams, with a particular focus on plastics due to their environmental impact.

Our factory setup is intentionally low-impact, using a fraction of the energy required by conventional plastics machinery, and we prioritise local suppliers wherever we can. We produce a core range of large-format panels and collaborate closely with clients on custom aesthetics or performance needs. Behind the scenes, we’re always experimenting; pushing boundaries with new materials and methods to expand what’s possible in circular design.
