Finnish pulp and paper manufacturer Stora Enso has introduced CarrEco Brown, a renewable material made entirely from fresh fibres.

The material is part of the company’s paper bag material portfolio and is intended to support the transition from plastic to renewable and recyclable materials in shopping and takeaway bags.

The fully recyclable solution features a three-layer structure made with Stora Enso’s patent-pending Tri-Ply technology, which is designed to offer high strength and tear resistance properties.

All the chemicals used by the material comply with US Food and Drug Administration (FDA) regulations, making it suitable for takeaway and grocery bags.

In addition, the material is safe for direct food contact.

CarrEco Brown is free from optical bleaching agents, while its smoothness and formation qualities are intended to make it an attractive option for brand owners looking for printable material.

To allow Stora Enso’s customers to expand to new segments within the paper bag market, the solution is available in grammages of 85gsm and higher.

Stora Enso Packaging Materials Kraftliners business segment director Oscar Duarte said: “Unbleached paper bags are a good fit with the preferences of today’s eco-conscious consumers.

“We are well-positioned to meet the growing demand for paper bags, especially in trending end-use areas such as takeaway food.

“Our newest material, CarrEco Brown, can help our customers seize these growth opportunities in a sustainable way.”

Stora Enso provides renewable products for the packaging, biomaterials, wooden construction and paper industries.

In November last year, the company expanded its Trayforma range for ready meals by launching Trayforma PET34, which contains less than 10% polyethylene terephthalate (PET) plastic.

The packaging can withstand temperatures of up to 220°C and can be processed in fibre-based packaging recycling streams due to its low fossil-based barrier material content.
