At present, domestic disposable paper cups can be divided into three types according to their uses: cold drink cups, hot drink cups, and ice cream cups; according to the use of paper cups, the coating is also divided into three types, one is wax-coated cups, and the other is polyethylene-coated cups. Membrane cups and straight wall double wall cups.
Wax cups are coated with a layer of wax for water insulation.
The polyethylene-coated cup is a film covered with polyethylene on the cup wall.
The cup wall of the straight-wall double-layer cup has two layers of paper, and there is air between the paper and the paper, and the heat insulation is very good.
At present, the most commonly used in the market is the disposable paper cup made of polyethylene coating material, which is safer. The production process of polyethylene-coated paper cups is base paper-coating-printing-die-cutting-molding-packaging. This kind of paper cup generally has a layer of coated paper on the inner wall and a layer of paper on the outside. Some manufacturers will pour a film on the outer wall of the paper cup after printing. The qualified disposable paper cups that can be bought now are almost all coated paper cups, and wax-coated disposable paper cups are basically no longer found.
Ordinary paper cups have a heat resistance of 100 degrees, while hot drink paper cups require a relatively high heat resistance temperature, so improvements were made during the production process to increase the heat resistance to 1000 degrees. A paper cup is a kind of paper container made by mechanically processing and bonding raw paper (white cardboard) made of chemical wood pulp, and its appearance is cup-shaped.
Is it good to put hot drinks in disposable paper cups?
Some of the inner walls of disposable cups are indeed waxed because wax has a water-repellent effect. If the wax used is edible wax, "for example, if it is beeswax, then it does not matter if you pour hot water into the cup, etc., even if it is dissolved in water, it will not be harmful if it enters the human body. If it is industrial wax, then It's not just the question of whether the first glass of water can be drunk, "Even if the glass is poured with many glasses of water, it is still undrinkable, because there are many impurities in the industrial wax, which is harmful to the human body.
If disposable paper cups are specifically designed for hot drinks, they are also suitable for hot drinks. However, not all paper cups are created equal and some may not be suitable for holding hot beverages.
The main problem with using paper cups for hot beverages is that the heat can cause the cups to weaken and possibly leak or even collapse. To prevent this from happening, paper cups designed for hot drinks should be coated with polyethylene on the inside to make them heat resistant and prevent liquid from seeping out.
Another consideration is the size and thickness of the paper cups. Thicker mugs with more surface area can help insulate drinks and protect your hands from the heat.
Overall, if you use disposable paper cups for hot beverages, it's important to choose good-quality cups that are designed for hot beverages. Also be careful when handling mugs, especially when the contents are hot, to prevent spills or burns.
