AI Technical Summary
While pursuing environmental protection, existing biodegradable plastic food trays struggle to balance load-bearing capacity and biodegradability, as their design neglects the contact area with microorganisms, thus affecting the decomposition rate.
Several downward-extending support grooves and through grooves are provided on the pallet body, and circular ribs are provided on the inner wall of the bottom of the support grooves. A support cover is formed around the pallet, and an abutment edge is provided at the bottom of the support cover to improve load-bearing capacity and stability, while increasing the contact area of microorganisms.
By optimizing the structural design, the load-bearing capacity and stability of the plastic pallet were improved, while the degradation rate was accelerated.

Abstract
Description
Technical Field
[0001] This utility model belongs to the field of plastic tray technology, and in particular relates to a biodegradable plastic tray for food. Background Technology
[0002] Biodegradable food plastic trays are made of biodegradable materials such as PLA (polylactic acid) and starch-based plastics. These materials can be decomposed by microorganisms in the natural environment and eventually transformed into harmless substances such as carbon dioxide and water. They are non-toxic and harmless, will not contaminate food, and ensure food safety.
[0003] Currently, biodegradable food plastic trays on the market face the challenge of balancing load-bearing capacity and biodegradability while pursuing environmental protection. The design of biodegradable food plastic trays often focuses on structural integrity and load-bearing capacity, while neglecting the optimization of the contact area with microorganisms, which affects the decomposition rate. Utility Model Content
[0004] The purpose of this utility model is to address the challenge of balancing load-bearing capacity and biodegradability in the current market for biodegradable food plastic trays, which often focus on structural integrity and load-bearing capacity while neglecting the optimization of contact area with microorganisms, thus affecting the decomposition rate. Therefore, this utility model proposes a biodegradable food plastic tray.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a biodegradable plastic food tray, comprising a tray body, wherein the tray body is provided with a plurality of downwardly extending bearing grooves, and a plurality of through grooves are provided between the plurality of bearing grooves, wherein a support cover is formed by downwardly extending the periphery of the tray body, and an abutment edge is provided on the bottom periphery of the support cover.
[0006] As a further description of the above technical solution:
[0007] The abutment edge and the bottom of the bearing groove are on the same horizontal line.
[0008] As a further description of the above technical solution:
[0009] The main body of the tray has a polygonal cross-section.
[0010] As a further description of the above technical solution:
[0011] The bottom inner wall of the bearing groove is provided with a number of circular ribs, and the number of circular ribs form a number of support grooves on the back side of the bottom of the bearing groove.
[0012] As a further description of the above technical solution:
[0013] Several of the aforementioned bearing grooves are arranged in a triangular pattern.
[0014] As a further description of the above technical solution:
[0015] The support cover may also have several friction patterns on its periphery.
[0016] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:
[0017] 1. In this utility model, by setting a plastic tray as a cover, the cover is supported on all four sides and directly abuts against the table. Several downward-extending bearing grooves are set in the middle of the tray body, and several circular ribs are set on the inner wall of the bottom of the bearing grooves. A support groove is formed on the back side that is horizontal with the abutment edge. This structure improves the overall load-bearing capacity and stability of the plastic tray, while also ensuring the maximum contact area with microorganisms and improving the subsequent degradation speed.
[0018] 2. In this utility model, by setting through grooves between several bearing grooves, the through grooves can not only increase the contact area, but also connect multiple bearing grooves, so that when one bearing groove is subjected to force, the other bearing grooves can be supported by the through grooves, thereby improving the stability of the entire pallet.
