Fiber material paper-plastic dish type product and manufacturing method thereof

Abstract

The invention discloses a fiber material paper-plastic dish type product and a manufacturing method thereof. The paper-plastic dish type product is mainly used for containing foods or objects and is provided with a containing table, a microbend is arranged on each of the four sides, the outer side of each microbend rises to form a short and shallow ascending inclined face, a bent arc inclined faceis integrally connected between every two adjacent ascending inclined faces of the four sides, and a groove mark is formed on the common top edge of each ascending inclined face and the correspondingbent arc inclined face. Each groove mark extends outwards to form an upward-concaved arc side wall, at least one transverse groove mark is formed on the arc face of each arc side wall, and a hemstitch wall is integrally connected between every two adjacent arc side walls and is formed by multiple upward-protruding small wall bodies through bed moulding grooves. The hemstitch walls and the side adjacent arc side walls are integrally formed, and the bottom edges of the hemstitch walls are in contact with the groove marks on the top edges of the ascending inclined faces and the bent arc inclinedfaces. In manufacturing of the paper-plastic dish type product, a lamellar pulp board is adopted as an initial material, and after the steps of cutting, coating, standing, hot press forming and edgecutting, the paper-plastic dish type product is completed.

Description

【Technical field】 [0001] The invention relates to a fibrous paper-plastic disc-shaped product and its manufacturing method, especially a paper-plastic disc-shaped product manufactured by dry hot pressing, which is recyclable, naturally decomposable, light in weight, and relatively durable. load and many other excellent characteristics. 【Background technique】 [0002] The so-called "pan-shaped product" refers to a kind of side inclination angle is relatively large, the depth is small (shallow), and the bottom part can form a platform for holding food or articles, such as: shallow dish, shallow Plates, dinner plates, buffet plates, fruit platters, food platters, etc. The early plate-shaped products were made of metal and carved out of wood. Later, there were plate-shaped products that were molded with resin materials. Generally known as plastic disc products. [0003] "Plastic products" made of resin materials (including plastic disc products) have been used for a long time ...

AI Technical Summary

Problems solved by technology

The reason is that the finished product of "pan-shaped product" is mainly used to hold food or articles, so it must have the characteristics of bearing a considerable load. If it cannot withstand a considerable load, the surface layer may break when lifting the food or articles, or even fall. Bad stuff

That is, because the disc-shaped products produced by the general manufacturing method of paper-plastic products cannot meet the requirements of considerable load resistance, no paper-plastic disc-shaped products with excellent functions have come out.
