For paper cups, it can be divided into "cold drink cups" and "hot drink cups". Maybe everyone will think that paper cups are nothing more than cold water and hot water. What is the difference?
In fact, the two types of paper cups have different quality requirements for paper cup materials due to different uses and processing forms. In addition to meeting the requirements of its packaging and processing performance, the customized disposable paper cup materials must also have certain printing suitability, and the printing of paper cups must also meet the conditions of heat sealing in the processing and forming of paper cups.
It is usually used for the packaging trade of hot beverages, and the material used for its processing is the single-sided PE composite paper, 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 needs of hot drinks, this type of paper cup needs to have a certain degree of thermal insulation after processing. Therefore, these products usually require a certain thickness and stiffness of the paper to increase the thermal insulation of the paper cup. Publishing and printing, the larger the volume, the more the paper used. thick.
Due to the needs of the market, printing on paper cups is a way of publicity adopted by many manufacturers. At the same time, the exquisite printing patterns also give the paper cups a gorgeous coat, bringing good visual enjoyment to consumers.

Cold drink cups are divided into two types according to different processing methods. One is that the paper has good anti-permeability through the wax dipping process after the base paper is printed and made into the cup. sex.
Two different processing forms of paper cups have different printing requirements for their materials. Paper cups processed by dipping wax are printed on the paper surface, and there are no special requirements for raw materials as far as printing itself is concerned. For the paper after double-sided PE compounding, in order to obtain a good printing effect, the compounded paper needs to be specially treated to obtain it.
