Learn About Paper Cups

The paper cups that first came out were conical in shape, made by hand, glued together, easy to separate, and used as soon as possible. Later folding paper cups, with folds added to the side walls, made it more difficult to print patterns on these folding tables, and the effect was not ideal.
Waxed paper cups
In 1932, waxed two-piece paper cups were introduced, and their smooth surface could be printed with a variety of exquisite patterns to improve the promotional effect. On the one hand, the paper cup can avoid direct contact between the beverage and the paper material, and can protect the adhesion of the glue and enhance the toughness of the paper cup;
On the other hand, the thickness of the side wall is also increased, so that the strength of the paper cup is greatly improved, thereby reducing the amount of paper necessary to make a stronger paper cup and reducing the production cost.
Straight-walled double-walled cups
In order to expand the application range of paper cups, in 1940, straight-walled double-layer paper cups were introduced to the market. These paper cups are not only easy to carry, but also can be used to hold hot beverages. Latex-coated single-layer waxed cups are widely used in vending machines to hold hot coffee.
Laminated plastic-coated paper cups
Some food companies are starting to coat polyethylene on cardboard to increase the barrier and sealing properties of carton packaging. Solved the problem of affecting product quality due to the melting of the coating material. At the same time, the polyethylene paint is smoother than the original wax paint, improving the appearance of the paper cup.
