Abstract:
Disclosed are a paper-plastic tray-shaped product made of a fibrous material, and a manufacturing method therefor. The paper-plastic tray-shaped product is mainly used for holding food or an article, and is provided with a holding platform (10) having micro-bends (11) provided on the periphery thereof. An outer side of each micro-bend (11) rises to form a short and shallow ascending bevel (20). A curved-arc bevel (21) is integrally connected between the ascending bevels (20) on the periphery. A common top edge of the ascending bevel (20) and the curved-arc bevel (21) has a groove trace (22) formed thereon. An upwardly concave arc-shaped side wall (30) extends outwards from the groove trace (22). At least one transverse groove trace (31) is formed on an arc face of the arc-shaped side wall (30). A border-decorated wall (40) is integrally connected between two adjacent arc-shaped side walls (30) and is formed from a plurality of small wall bodies in the form of upward reliefs with a concave decorative groove (41) interposed therebetween. The border-decorated wall (40) and the adjacent arc-shaped side walls (30) are integrally formed. A bottom edge of the border-decorated wall (40) comes into contact with the groove trace (22) on the top edge of the ascending bevel (20) and the curved-arc bevel (21). The paper-plastic tray-shaped product is manufactured by taking a thin sheet-shaped pulp board as a starting material, and a paper-plastic tray-shaped product is completed after the steps of cutting, coating, standing, hot-press forming and trimming are executed.
