TemperPack granted patent for new packaging material
August 02, 2019 - United States Of America
TemperPack, leader in sustainable thermal packaging, has been granted patent for its advanced thermal and protective packaging material made from bonded polysaccharide particles by the US Patent Office. This patent is the first related to ClimaCell, the company's latest and most advanced material, which was introduced to the market late last year.
ClimaCell is the first packaging material to match the thermal and cushioning properties of expanded polystyrene (EPS) that has also received the "Widely Recyclable" designation from How2Recycle.
ClimaCell was developed out of an effort to find a scalable alternative to EPS, which is more commonly known as Styrofoam. "We wanted to create an affordable material that could be used in multiple markets. That required us to come up with a manufacturing platform that would be massively scalable and run on widely available feedstock," stated James McGoff, co-CEO of TemperPack.
To achieve sustainability at scale, the company experimented with hundreds of formulations and materials including nonwoven battings comprising natural, synthetic, and paper fibres, macerated paper, shredded kraft and newsprint, molded pulp, corrugated designs, embossed tissue, filled honeycomb, mushroom-based materials, natural and synthetic extruded foams, and thermoformed plastics such as rPET.
The company landed on the product its calls ClimaCell. ClimaCell and EPS have a 1:1 R-Value when comparing equal thicknesses but ClimaCell is made from rapidly renewable materials and reduces carbon dioxide equivalent emissions by over 90 per cent compared to EPS. ClimaCell is lightweight, food safe, moisture-resistant, and ships flat for efficient transport and storage.
"This patent is a huge development for us, from a market leadership perspective. But what's really exciting is we've already produced millions of units and are actively working with companies in the life sciences and perishable foods space. This is a proven product and technology which enables us to be cost competitive with EPS," said McGoff. (SV)
