PHA (Polyhydroxyalkanoates) is a natural polymer material synthesized by microorganisms with good biodegradability and environmental friendliness. When this material is used as a coating, it can form a special aqueous coating that is used to treat the surface of paper to achieve water and oil repellency. This type of specially treated paper is known as PHA coated greaseproof paper.
Features
- Environmental protection: PHA itself is a renewable resource produced by microbial fermentation, and its production process has less impact on the environment; at the same time, the material is completely biodegradable and can be decomposed into carbon dioxide and water under natural conditions, which will not cause environmental pollution.
- Functionality: The paper treated with PHA aqueous coating has excellent waterproof and oilproof performance, which is suitable for a variety of applications that require resistance to liquid penetration.
- Safety: Since PHA comes from natural substances and is non-toxic, food packaging materials treated with this coating are safe for human health.
- Adaptability: PHA aqueous coatings can be formulated to meet the needs of different types of paper and specific functional requirements.
Applications
- Food Packaging: Used on disposable packaging materials such as fast food containers, hamburger paper, French fries bags, etc. that are in direct contact with food, which not only ensures food safety but also facilitates recycling or natural degradation. As bakery products such as cake trays, baking tray matting paper, etc., not only to facilitate the cleaning and can reduce the pollution caused by grease residues.
- Medical health: Producing disposable medical supplies packaging, such as mask outer packaging, surgical gown bags, etc., helps to improve product health standards and reduce the impact of medical waste on the environment.
- Daily necessities: Producing a variety of anti-oil paper products in life, such as absorbent paper for kitchen, anti-sticky paper on barbecue grill, etc., which is not only convenient to use but also effective in preventing greasy contamination of other items.
- Industrial manufacturing: PHA water-based coated greaseproof paper can also be found in certain industrial areas, such as as part of the packaging materials for electronic components, or used in manufacturing processes that require isolation of grease on the worktop coverings.
