PulPac and HSMG have developed an innovative approach for water and oil barriers for PulPac’s Dry Moulded Fibre technology.

A thin, stretchable sheet of substrate applied with HSMG’s Protean solution is layered onto the fibre mat as the article is formed.

The heat pressure of the forming process bonds the HSMG carrier sheet to the product. The comanies says the result is a strong, recyclable, biodegradable non-fossil alternative to single-use plastic that holds up to hot drinks.

“We are enthusiastic about the performance of the HSMG barrier technology platform,” said Sebastian Roos, chief technology officer at PulPac. 

“This solution is plant-based, plastic-free, biodegradable and recyclable, all important qualities to our customers, and crucial for saving the planet from plastics.

“Our technology has pioneered fibre forming, making it possible to manufacture paper packaging without wasting valuable water resources or energy, and significantly reducing CO2, at unit economy that is competitive.

“We are fast approaching a tipping point, where the single-use plastics items that can be replaced will become obsolete in favour of competitive and sustainable alternatives.”

Last year HSMG and PulPac worked in collaboration to develop sustainable chemicals, barriers and materials for Dry Moulded Fibre. This year they will first feature Protean technology in a coffee lid for Sweden’s Max Burgers’ quick service restaurant chain. 

Other Dry Moulded Fibre applications such as hot cups lids and takeaway items will follow, and will be available for PulPac licensees. 

“PulPac’s Dry Moulded Fobre technology is a good fit with HSMG’s barrier chemistry solutions,” said Jonathon Spender, chief technology officer at HSMG. 

“The Protean carrier sheet integrates readily into the manufacturing process, and is an ideal way to target the barrier to the function required. We are thrilled that Protean technology will be available for licensing to PulPac customers.”

Coffee lids will be the first Dry Moulded Fibre product using HSMG PROTEAN oil and water barriers.
