Plant fiber plate structure

Abstract

This disclosure discloses a plant fiber dinner plate structure comprising a paper base and a palm leaf covering layer. The paper base defines the receiving space and has an inner surface facing the receiving space. The palm leaf covering layer is fully laid and hot-pressed onto the inner surface of the paper base, resulting in a seamless bond between the palm leaf covering layer and the paper base. Through the above, this disclosure directly forms a water-resistant layer to prevent penetration by seamlessly hot-pressing the fully laid palm leaf covering layer to the paper base. This provides waterproof and leak-proof performance without the need for chemical coatings when holding hot food, and reduces environmental impact during recycling.

Claims

1. A plant fiber plate structure comprising: a paper base defining an accommodating space, the paper base having an inner surface facing the accommodating space; and a palm leaf covering layer fully laid and hot-pressed onto the inner surface of the paper base, such that the palm leaf covering layer and the paper base are seamlessly bonded.

2. The plant fiber plate structure as described in claim 1 further includes a flat edge structure, wherein the palm leaf covering layer has an outer edge, the paper base has a peripheral edge, the outer edge and the peripheral edge are flush with each other and together constitute the flat edge structure.

3. The fiberboard tray structure as described in claim 1, wherein the paper substrate includes a bottom wall and a side wall extending from the periphery of the bottom wall.

4. The fiber-reinforced plate structure as described in claim 3, wherein an obtuse angle is defined between the bottom wall and the side wall to make the accommodating space a shallow plate structure.

5. The plant fiber plate structure as described in claim 1, wherein the palm leaf covering layer is a water-resistant layer formed by overlapping and cutting a plurality of long strips of palm leaves.
