  • Sugar cane pulp: The fiber left after the sugar cane is squeezed, which has strong heat and oil resistance, is suitable for cold and hot food, and is a fast-growing renewable resource.

  • Paper pulp: Usually processed from wood pulp or waste paper, suitable for cold and dry food.

  • Bamboo fiber: Extracted from bamboo, it has good strength and durability, and is also a fast-growing renewable resource.

  • Corn starch: Made from corn, it is a compostable plastic alternative, commonly used to make bowls, lunch boxes, etc.

  • Coconut shell: Made from the natural fiber of coconut shell, it has a unique appearance and strength.


It must be noted that regardless of the type of material used, they must not contain plastic coatings in order to be more completely composted and degraded.
