PHA is a biodegradable polymer synthesized by microorganisms, which has attracted much attention because of its good biocompatibility and environmental friendliness. When this material is used as a coating applied to lunchbox paper, PHA coated lunchbox paper is formed. These products are designed to provide a safe and environmentally friendly alternative to traditional plastic or wax coated food packaging materials.
Features
- Environmentally friendly: As a naturally sourced biopolymer, PHA can be completely decomposed into carbon dioxide and water under natural conditions, causing no pollution to the soil.
- Safety: Since it comes from microbial fermentation process, it does not contain any harmful chemicals and is harmless to human health.
- Water and oil repellency: Through special processing technology, the PHA coating can be made to have excellent ability to block the penetration of water and oil, thus ensuring the freshness and taste of food.
- Good breathability: Compared with some synthetic plastics, PHA coating allows a certain degree of gas exchange, which helps to maintain the balance of humidity inside the food and prolong the shelf life.
Applications
- Fast food takeaway industry: As consumers' awareness of green consumption increases, more and more catering companies are adopting PHA water-based coated lunch box paper as takeaway packaging material to reduce environmental pollution.
- Frozen food packaging: PHA coated lunch box paper is also very suitable for frozen food packaging due to its good thermal insulation effect and prevention of condensation dripping.
- bakery products: for bread, cakes and other baked goods that need to be kept dry and avoid greasy feeling, the use of PHA coated lunch box paper can effectively meet these requirements.
- Fresh fruit and vegetable protection: the use of PHA-coated paper made of pouches or trays, can be used to store fresh fruits and vegetables, both to keep the surface of fruits and vegetables dry and prevent the invasion of external bacteria.
