PHA (Polyhydroxyalkanoates) is a biodegradable polymer material produced by microorganisms through a fermentation process. PHA water-based barrier coating paper (PHA coated paper) is a new type of environmentally friendly paper product that enhances the performance of paper by applying a layer of aqueous coating containing PHA on the surface of traditional paper. This coating technology not only improves the physical properties of paper, such as water resistance, abrasion resistance and printability, but is also environmentally friendly due to its biodegradability. The features of PHA water-based barrier coating paper are:
Environmentally friendly: PHA, as a bioplastic of natural origin, can be completely decomposed into carbon dioxide and water under natural conditions, and will not cause environmental pollution.
Good barrier properties: PHA coating has excellent moisture and oil resistance, extending the shelf life of the contents of the package.
Enhanced mechanical strength: compared with untreated ordinary paper, the addition of PHA coating improves its tear resistance and folding resistance.
excellent printing adaptability: smooth and delicate surface is conducive to improve image clarity and color saturation, suitable for high-quality graphic output.
Sustainable development: The use of renewable resources to produce PHA reduces dependence on fossil fuels while promoting the development of a circular economy.
