When did waxed paper cups start to be produced? What are the characteristics of the cup making machine?

Everyone knows that the paper cup machine is a kind of paper cup production, which has the characteristics of high efficiency and good molding, which can well meet the needs of the public. So do you know when the waxed paper cups started to be produced? What are the characteristics of the cup making machine? The following is the classification, production materials and characteristics of paper cup machines from Hongxin paper cup machine manufacturers. Classification of paper cups produced by paper cup machine:

1. Waxed paper cups In 1932, a two-piece set of waxed paper cups, whose smooth surface can be printed with various exquisite patterns, can improve the publicity effect. On the one hand, paper cup waxing can avoid the direct contact between the beverage and the paper, protect the adhesion of the glue, and enhance the durability of the paper cup; on the other hand, it also increases the thickness of the side wall, which greatly improves the strength of the paper cup and reduces the production time. The amount of paper required for stronger cups, thus reducing production costs. As wax paper cups become cold drink containers, people also want a convenient hot drink container. But hot drinks will melt the wax layer on the inner surface of the cup, and the bond will separate. Therefore, general wax paper cups are not suitable for holding hot drinks.
2. In order to expand the application range of paper cups, straight-wall double-layer paper cups were launched in 1940. This paper cup is not only easy to carry, but can also be used to hold hot drinks. Since then, manufacturers have coated the cups with latex to mask the paper’s “cardboard smell” and enhance the cup’s leak-proof properties. Single-layer wax cups with a latex coating are widely used to hold hot coffee in vending machines.

3. Plastic-coated paper cups Some food companies have begun to coat the cardboard with polyethylene to increase the barrier and air tightness of the paper packaging. Since the melting point of polyethylene is much higher than that of wax, paper cups coated with polyethylene can be used to hold hot drinks, which can solve the problem that the melting of the coating material affects the quality of the product. At the same time, the polyethylene coating is smoother than the original wax coating, improving the appearance of the paper cups. In addition, its processing technology is cheaper and faster than methods using latex coatings.
