Biodegradable coated paper bowl is an innovative product that combines the concept of environmental protection with modern food packaging technology. It consists of two parts: firstly, the main structure - paper bowl body, which is usually made of natural plant fibers such as bamboo, wheat straw, bagasse, etc. as raw materials, after pulping, molding, drying and other processes; and secondly, the surface treatment layer - biodegradable coating, which is a special film designed to improve the performance of the paper bowl and ensure food safety. This is a special film designed to improve the performance of paper bowls, extend their service life and ensure food safety, and consists of biodegradable polymer materials.
Features
- Environmentally friendly: The core value of biodegradable coatings lies in their low impact on the environment. Unlike traditional plastics or other non-biodegradable materials, these coatings are able to chemically decompose through the action of microorganisms within a certain period of time under specific conditions after use (e.g. in soil, compost or certain aqueous environments), and ultimately convert into carbon dioxide, water and biomass, avoiding long-term retention in the environment and causing pollution.
- Enhanced functionality: Biodegradable coatings give paper bowls a range of practical properties, including:
- Water and grease resistance: The coating prevents water and grease from penetrating the interior of the paper bowl, keeping food fresh and preventing any degradation of the user experience due to leakage.
- Improved heat resistance: the coating provides a certain degree of thermal stability, enabling the paper bowl to withstand certain high temperatures, adapting to the needs of hot food packaging, and is not easily deformed or softened by heat.
- Barrier properties: Preventing the exchange of oxygen, aroma and odour, it helps to maintain the flavour of food and prolong the shelf life.
- Food safety: Biodegradable coating materials must comply with strict food safety regulations and standards to ensure that there is no migration of hazardous substances in contact with food, and that they are not harmful to human health. In addition, the biodegradation products of the coating should also be safe and non-toxic, without causing long-term negative impact on the environment.
Applications
- Food service industry: Biodegradable coated paper bowls are widely used in fast food restaurants, cafes, cold drink shops and other catering establishments as disposable lunch boxes, soup bowls or snack containers, replacing traditional plastic or foam products to meet consumers' demand for convenient packaging while responding to environmental protection demands.
- Food retailing and distribution: With the rapid development of online takeaway market, biodegradable coated paper bowls have become the ideal packaging containers, suitable for all kinds of pre-packaged food, cooked food, frozen food sales and distribution, which can not only protect the quality of the food, but also reflect the responsibility of the merchants for environmental protection.
- Large-scale activities and gatherings: In various outdoor activities, celebrations, conferences, exhibitions and other occasions, biodegradable coated paper bowls are widely used to provide temporary catering services due to their convenience and environmental protection attributes, reducing the use of disposable plastic tableware, and helping to achieve the goal of zero-waste or low-carbon.
- Family and personal consumption: More and more families and individuals are choosing to use biodegradable coated paper bowls in their daily meals, especially in outdoor activities such as picnics and camping, where they are convenient to carry and easy to dispose of without leaving a lasting environmental footprint.
