MOSCOW (MRC) -- Most pearls are produced by oysters in the saltwater environment of the world’s oceans — which makes it fitting that the first ever bottle made completely from post-consumer plastic recovered from the oceans has a resemblance to a pearl, as per Canplastics.
Sporting a silver metallic, pearlescent-effect finish due to some compounding expertise by colourant and additive maker Techmer PM LLC, the world’s first HDPE bottle molded from 100 per cent ocean-bound plastic has just hit the market. Techmer partnered with global sustainable technology developer Primal Group, Ontario, Calif.-based blow molder Classic Containers Inc., and plastics recycler Envision Plastics Industries LLC, of Reidsville, N.C., to manufacture the bottle, which is completely made from recycled plastic collected from at-risk ocean areas and sold by Envision under the brand name OceanBound Plastic.
The project was challenging for several reasons. First, Primal Group, which is headquartered in Miami, Fla., wanted a specific colour and reflective finish on the bottle, which is being used to package its ViTA brand of natural, plant science-based personal care products. Typically, an extrusion grade of PE would be needed in the masterbatch as a carrier for the colourant, but that wasn’t an option in this case because Primal Group wanted the end product to be made completely from OceanBound Plastic. “The high-viscosity recycled plastic recovered and supplied by Envision is a fractional melt that makes the colourant’s metallic particles without shearing them and ruining the ultimate visual effect,” said Savvas Roubanis, a sales engineer with Los Angeles-based Techmer. “Compounding of the recipe required additional process design to assure the metallic and pearlescent effect pigments could be smoothly compounded into the recovered plastic."
A final potential hurdle was economic, and came at the blow molding stage: If Classic Containers couldn’t manufacture the bottles within its normal, everyday processing window — which was vital to producing a bottle at the desired price point — the project wouldn’t fly. “The material processed amazingly well without any concerns,” said Kevin Tibbets, executive director of sales for Classic Containers. “Aside from the necessary additives, pigments, and non-resin components that we needed to process it effectively, the balance of the recipe is 100 per cent OceanBound resin."
