Lining paper is provided on the surface of the corrugated paper cup, and a corrugated paper cup holder is provided. The corrugated paper cup holder is provided with an inserting part capable of being inserted into the bottom of the cup, and a clamping part capable of being clamped with the mouth of the cup. The bottom of the cup holder is provided with a through hole. The cup body is provided with a holding part, the holding part is provided with a holding hole, and the joint between the holding part and the cup body is provided with creases.
The cup body is provided with a holding groove for hiding the holding part. There are two holding parts and two holding grooves, and the two holding parts can abut against each other. The insertion part includes an annular insertion protrusion, and the shape of the inner surface of the annular insertion protrusion is the same as that of the bottom of the cup.
The anti-compression test process is divided into four stages: the first is the pre-loading stage to ensure that the corrugated paper cup is in contact with the pressure plate of the compression machine; the second is the stage when the horizontal pressure line is pressed down, and the load is slightly increased at this time, and the deformation changes greatly. ; The third is the compression stage of the side wall of the corrugated cup. At this time, the load increases rapidly and the deformation increases slowly; the fourth is when the corrugated paper cup is completely destroyed, which is the crush point of the corrugated paper cup.
Corrugated paper cups have the characteristics of no pollution, no peculiar smell, good stiffness, good texture, dual-use for hot and cold, natural degradation, food-grade materials, and environmentally friendly printing. The food-grade PE coated paper used has a delicate surface, soft printing color, easy processing and forming, and automatic bonding under high temperature and high pressure. Paper cups are widely used in fast food, restaurants, stations, terminals, insurance, civil aviation, medical care, finance, telecommunications, government agencies and other enterprises and institutions.
