A compostable blown film article that includes PHA produced in an enclosed blown film process. The blown film may include a wax additive that reduces the stickiness of the film.
A method for producing a home compostable biopolyester blown film including a biopolyester and enzymes for improved compostability. Enzymes are added during the extrusion process. To maintain temperature, the blown film process is enclosed and uses a climate control system to maintain temperature and climate within the enclosures.
A method for producing polyhydroxyalkanoate (PHA) blown film comprising the steps of melting PHA material to form a molten mass with a viscosity ranging from 1400P to 1600P at 340°F to 350°F (melting point of PHA), forming a bubble from the resulting molten mass and collapsing the bubble to form a film. Furthermore, due to the tight processing window or PHA compared to other blown films, PHA benefits from being produced using an enclosed climate-controlled blown film process as the climate can be controlled within the enclosure to ensure the tight processing window is maintained.
