Problems solved by technology

[0003] Tableware can be divided into metal tableware, porcelain tableware, wooden tableware, and plastic tableware according to its material. Among them, tableware made of plastic materials are mostly bowls, plates, plates, etc. used to hold food. However, the existing tableware for holding food has the following technical problems: 1. The tableware is mostly made of a layer of plastic material, which has low strength and is prone to dents during use, resulting in inconvenient use and even making food 2. In order to control the cost, the material and processing method of the existing disposable tableware are almost simple and rough, and the quality and sanitation of the tableware cannot be guaranteed. ; 3. Disposable tableware is easy to cause garbage pollution after use; 4. Since the same tableware uses the same material, the inner and outer surfaces of these tableware are usually the same color, and the same color leads to the color of the tableware. Too single, it is difficult to attract customers to buy, and reduce the appetite of users, and as a decoration or decoration, its decorative effect is also poor

Abstract

The invention relates to double-color thin-wall plastic tableware and a processing method thereof, and belongs to the technical field of tableware. The tableware comprises a body. The body comprises a round bottom in the middle and a conical flange extending to the periphery of the round bottom. The body is formed by multiple layers of sheets in a laminated mode and comprises an upper surface layer and a lower surface layer, the sheets are tightly attached to one another, the thickness of the sheets ranges from 0.2 mm to 0.7 mm, the sheets forming the upper surface layer and the lower surface layer have different colors, and the sheets are made of plastic, including polypropylene plastic (PP) and polystyrene plastic. Because the tableware is formed by the multiple layers of sheets of different colors in a combined mode, the tableware has high strength without becoming sunk easily, and is convenient to use and more novel and bright-colored in appearance; because the tableware is made of the polypropylene plastic (PP) or the polystyrene plastic with reasonable compatibility, on one hand, the long-lasting antibacterial and antifungal property and other properties of the cup are effectively guaranteed, and on the other hand, environmental pollution caused by disposable tableware can be reduced; because the tableware is processed through a plastic sucking moulding process with special parameters, the final properties of the tableware are improved.
