PHA water-based emulsion is an environmentally friendly water-based coating with polyhydroxy fatty acid ester (PHA) as the main ingredient.PHA is a class of natural polymer material synthesized by microorganisms through fermentation process under specific conditions, which has good biodegradability and biocompatibility. After PHA is made into aqueous emulsion, it can be used as surface treatment agent for coated paper to improve the performance and appearance of paper.
Features
- Environmentally friendly: PHA comes from renewable resources and can be completely degraded to carbon dioxide and water in the natural environment, so it will not cause pollution to the environment.
- Safety: Non-toxic and harmless, friendly to human health, suitable for food packaging and other applications that come into direct contact with the human body or food.
- Durability: Although PHA itself is a biodegradable material, PHA emulsion can maintain good physical and chemical stability for a certain period of time after special modification treatment to meet the needs of different application scenarios.
- Multifunctionality: According to the formula adjustment, PHA aqueous emulsion can not only improve the gloss and smoothness of paper, but also enhance its water and oil resistance and tear strength.
- Easy to process: Compared with traditional solvent-based coatings, water-based emulsions are safer and more convenient, no need to worry about flammability and explosiveness during the production process, and can also effectively reduce the emission of VOCs.
Applications
- food packaging: coated paper made with PHA waterborne emulsion can be used for all kinds of food packaging, such as fast food containers, beverage cups, etc., which can ensure food safety and is conducive to environmental protection.
- High-end printed materials: For book covers, magazine inserts and other printed materials that require high quality, the use of PHA coatings can greatly enhance their visual effect and tactile experience.
- labeling materials: some special purpose labels (e.g. pharmaceutical labels) are also suitable for PHA coating technology to increase their durability and aesthetics.
- Other fields: In addition to the above typical applications, with the advancement of technology, PHA waterborne emulsions are expected to be developed and applied in more emerging markets in the future, such as smart packaging, wearable devices and other fields.
