Paper cup materials must have a certain printability
Disposable paper cups can be roughly divided into cold drink cups and hot drink cups according to their uses. The two paper cups have different requirements for the quality of paper cup materials due to their different uses and processing forms. In addition to meeting the requirements of packaging processing performance, paper cup materials must also have certain printability, and paper cup printing must also meet the conditions of heat sealing in paper cup processing and molding.
is usually used in the packaging trade of hot drinking products. Its processing material is paper made of PE single-sided composite, that is, single-sided coated paper. Generally, it is printed on the non-PE surface and directly printed on the paper surface. Due to the need for hot drinks, this type of paper cup needs to have a certain degree of heat insulation after processing. Therefore, this type of product usually requires a certain thickness and stiffness of the paper to increase the heat insulation of the paper cup. The larger the volume, the more paper it uses. thick.
Due to the needs of the market, printing on paper cups is a propaganda method adopted by many manufacturers. At the same time, the exquisite printing patterns also put on the paper cups a gorgeous coat, bringing good visual enjoyment to consumers. The printing of single-coated PE paper is carried out on paper, so except that the selected ink must meet the food hygiene requirements for e-commerce, other aspects of paper have similar effects on printing as ordinary paper.
Cold drink cups are divided into two types according to different processing methods. One is to make the paper have good anti-permeability performance through wax dipping process after printing the base paper, and the other is to make the paper have anti-permeability after the paper is laminated with PE on both sides of the paper. sex. The printing requirements of the materials for the two different processing forms of paper cups are different. For paper cups processed by dipping wax, the printing is cut on the paper surface, and there is no special requirement for the raw materials as far as the printing itself is concerned. For the double-sided PE composite paper, to obtain a good printing effect, the composite paper needs to be processed through special treatment.
