Nowadays, the application of disposable paper cups is very frequent. Many companies customize their own advertisements to promote disposable paper cups, which is also a very good means of publicity. Disposable paper cup factories were previously known as high energy consumption companies, which caused a lot of air pollution due to the consumption of printing paper, application of printing ink and technical processing technology. However, with the development of the times, this awareness has slowly changed. The disposable paper cup color printing factory has just begun to implement low-carbon environmental protection with practical actions. The specific measures are as follows.
1. Conical, pleated paper cups
The first paper cups that came out were conical, made by hand, glued together, easier to separate, and had to be used as soon as possible. Later folding paper cups added folds to the side walls to increase the strength of the side walls and the durability of the paper cups, but it was difficult to print patterns on these folded surfaces, and the effect was not ideal.
2. Waxed paper cups
In 1932, the first waxed two-piece paper cup came out, and its smooth surface can be printed with various exquisite patterns to improve the promotion effect. Waxing the paper cup, on the one hand, can avoid the direct contact between the beverage and the paper, and can protect the adhesiveness 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, thereby reducing the The amount of paper necessary to make stronger paper cups reduces production costs. With waxed paper cups becoming a container for cold beverages, there is also a desire to have a convenient container for hot beverages. However, hot beverages will melt the wax layer on the inner surface of the paper cup, and the adhesive mouth will be separated. Therefore, general waxed paper cups are not suitable for holding hot beverages.
3. Straight wall double cups
In order to expand the application scope of paper cups, in 1940, straight-wall double-layer paper cups were introduced to the market. This paper cup is not only easy to carry, but also can be used to hold hot beverages. Since then, the manufacturer has coated these cups with latex to cover up the "cardboard smell" of the paper and enhance the leak-proofness of the paper cups. Single-layer wax-coated cups with latex coating are widely used in self-service vending machines to hold hot coffee.
4. Plastic coated paper cups
Some food companies are beginning to coat polyethylene on cardboard to increase the barrier and seal of paper packaging. Since the melting point of polyethylene is much higher than that of wax, the new type of beverage paper cups coated with this material can ideally be used to hold hot beverages and solve the problem of affecting product quality due to the melting of the coating material. 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 the method using latex coating.
1. It is the expansion and research and development of low-carbon and environmentally friendly raw materials
Today, the raw materials of the disposable paper cup color printing factory are based on new biodegradable and recyclable materials, which reduces the working pressure of green ecological conditions, reduces pollutants, and also raises the "green barrier" for channel products. The use of poorly soluble raw materials is internationally prohibited. The promotion, manufacture and application of turquoise raw materials are of great significance both from a practical perspective and from the overall perspective of sustainable economic development.
2. The disposable paper cup color printing factory must have both product development and cost savings
The development and application of new technologies for energy conservation and emission reduction, replacing the rules and regulations of weapons and equipment with high energy consumption and high material consumption, and taking the road of sustainable development.
3. Disposable paper cup packaging and printing design scheme
If the design plan of the disposable paper cup color printing factory is appropriate, it can follow the design ideas of harmless treatment, ecologicalization and resource utilization, and evaluate the harm of its production to the natural environment from the determination of raw materials, production and processing, and printing technology. In these aspects, designers should follow simple, atmospheric and appropriate design principles, and the disposable paper cup color printing factory should hire effective and independent innovative designers. Only the two can design low-carbon and environmentally friendly disposable paper cup products.
