HDPE bottle made from 100 per cent ocean-bound plastics surfaces

April 13/2018

MOSCOW (MRC) -- Most pearls are produced by oysters in the saltwater environment of the worlds 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 worlds 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 wasnt 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 colourants 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 couldnt manufacture the bottles within its normal, everyday processing window which was vital to producing a bottle at the desired price point the project wouldnt 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."
