What are the plant-degradable materials suitable for water cup production?

Hello everyone, "Dong Dong Talk Cup" is here. As the market becomes more and more accepting of biodegradable materials, there are more and more types of food-grade plant biodegradable materials that can be used in the production of water cups. http://www.zhanyict.com/en/ProductsDetail-VB-10447.htmlToday, the editor will share with you what these biodegradable materials are and how long it takes them to start degrading in different environments.

1. Corn starch-based bioplastic (PLA)

Features: PLA is a polymer material made from corn starch or other plant starch through a sugar fermentation process. This material is very suitable for the production of drinking water cups because it is non-toxic, odorless and transparent. http://www.zhanyict.com/en/ProductsDetail-VB-10447.htmlPLA has good biocompatibility and biodegradability and can be completely degraded under industrial composting conditions.

Degradable time: In an industrial composting environment, PLA can be degraded within 3 months; however, in a natural environment or a home composting system, it takes longer, possibly more than a year.

2. Natural plant fibers

Features: Fibers are extracted from natural plants such as bamboo, straw or sugar cane, which can be processed to make biodegradable water cups. http://www.zhanyict.com/en/ProductsDetail-VB-10447.htmlThese fibers have high mechanical strength and can be used to make hard water cups. They have good moisture resistance and durability while maintaining compostability.

Degradable time: In a natural soil environment, this type of water cup may be completely decomposed within a few months to a year.

3. Polyhydroxyalkanoate (PHA)

Features: PHA is a fully degradable bioplastic produced by microorganisms such as bacteria under specific conditions. It is safe for food contact and can be used to make water cups. http://www.zhanyict.com/en/ProductsDetail-VB-10447.htmlPHA cups have excellent heat resistance and strength.

Degradation time: PHA can be degraded in soil and seawater environments, usually completely decomposed within a few months.

4. Polylactic acid fatty acid copolymer (PBS)

Features: PBS is produced by reacting polylactic acid (PLA) with polyols and acids made from renewable resources such as sugar cane or beetroot. The material has high biocompatibility and biodegradability. http://www.zhanyict.com/en/ProductsDetail-VB-10447.htmlIt is suitable for applications requiring high toughness and heat resistance.

Degradability: In industrial composting facilities, PBS can be degraded within a few weeks to a few months.

Choosing the right plant-based biodegradable materials not only helps reduce environmental pollution, but also adapts to market demand by providing safe and functional products. http://www.zhanyict.com/en/ProductsDetail-VB-10447.htmlWhen choosing these materials, manufacturers should consider the product's purpose, durability and ultimate environmental impact.
