Someone came to the house, took out the best wine, poured it in a disposable paper cup and drank it, and after pouring the liquor, the paper cup was soaked through and the wine flowed out.
A bottle of good wine was wasted, and it was poisonous.
Disposable paper cups can't be used for drinking, I don't know if you know.
Every New Year's holiday, when visiting relatives and friends, everyone uses disposable paper cups to make tea and drink wine for convenience, but long-term use of this paper cup is very harmful to the human body and may cause cancer.
There are two types of disposable paper cups commonly used, one is a cold drink cup and the other is a hot drink cup.
The original material of the paper cup is made of wood pulp into base paper, and then processed into a paper container, but the paper will seep water, and if it is used to hold water, it will pass through, so the inner wall of the paper cup needs to be coated with a layer of plastic film to prevent water from leaking out.
The two paper cups cannot be mixed
The cold drink cup can be used to hold carbonated drinks, ice water, etc., and the inner wall of the cold drink cup is coated with a layer of wax, in order to prevent condensation on the outer wall from affecting the feel, so there are both the inner wall and the outer wall.
However, this wax is not heat-resistant, and it will be relatively stable between 0 ° ~ 5 °, if it is used to hold hot water, the wax layer will melt into the water, and it will be harmful to health after eating.
The inner wall of the hot drink cup is coated (PE), that is, polyethylene, which has the effect of waterproof and oil-proof, high temperature resistance, and a melting point between 120 ° ~ 140 °.
However, there are many low-quality paper cups on the market, and manufacturers will use recycled polyethylene in order to reduce costs.
This material contains a lot of harmful compounds, and the heat resistance is low, once it is filled with hot drinks, such as boiling water to make tea, coffee, the toxic substances in the paper cup will dissolve, released into the hot drink, harmful to human health.
What are the dangers of disposable paper cups?
When many unscrupulous manufacturers make paper cups, cold drink cups are coated with industrial paraffin, which will cause serious damage to the nervous system and hematopoietic system after this harmful substance enters the human body.
Moreover, when many people use disposable paper cups, cold cups and hot cups are mixed.
If you are unfortunate enough to use a cup of inferior cold drink to fill the hot water, the water temperature exceeds 40 °C, the wax will melt, and all harmful substances will be inhaled by the human body.
In addition, in order to make the paper cup look whiter, the manufacturer adds a large number of fluorescent agents and brighteners to the raw materials, and once this fluorescent substance enters the human body, it will become a potential carcinogenic factor.
In addition, many inferior paper cups, after being filled with hot drinks, will produce a large number of microplastic particles, which will enter our blood circulation, causing immunotoxicity, neurotoxicity, endocrine toxicity, and will also damage human reproductive function, cause digestive tract inflammation, damage to the liver, kidneys, etc.
Why can't paper cups hold liquor?
A professional quality inspection agency tested 80 batches of paper cups on the market, and found that 47 batches of paper cups had leaks after being filled with liquor, of which 6 batches of paper cups were deformed and cracked.
This is because alcohol is highly permeable and miscible with the organic solvents in paper cups.
In order to make the paper cup more beautiful and beautiful, manufacturers usually print patterns on the paper cups.
These patterns require the use of environmentally friendly inks, however, some manufacturers use inks that contain toxic solvents such as benzene or toluene.
After drinking, it will not only affect the taste of the wine, but also cause harm to the human body, such as affecting human white blood cells, causing blood diseases and causing cancer.
Moreover, paper cups will have small polyethylene molecules at the stitching place, and the small polyethylene molecules of the variant are easy to be dissolved by alcohol.
If you use a paper cup to fill the wine, it is very dangerous because polyethylene is absorbed by the human body and can cause disease.
Therefore, there is a clear provision in the national standard that paper cups need to be clearly marked with "no alcoholic beverages", but many people do not notice it in daily life.
How to choose a paper cup?
(1) Look at the testing standard:
GB/T 27590-2011 纸杯。
QB/T 4032-2010 纸杯原纸。
This is a test report that proves that the paper cup is in line with the national standard, and the paper cup that meets the standard will be guaranteed in terms of size, material, safety performance, and hygienic performance.
And pay attention to whether there is no production license number, QS logo, the address, name, production date, expiration date of the manufacturer, etc.
(2) Judging from the appearance:
Look at whether the printing pattern of the paper cup is clear and flawless, whether there are scratches, burrs, etc. on the cup body, and whether the bottom of the cup is flat and without warping.
It is recommended to choose a paper cup with few patterns and no obvious color spots.
(3) Pinch and press by hand:
Squeeze gently by hand, if it is a high-quality paper cup, it will be harder and have a certain resilience, while the inferior paper cup is softer after pinching, there is no resilience, and it is easy to flatten it when pinched.
(4) Sniff it:
If it smells peculiar, especially ink or mold, it must be a low-quality paper cup, so don't buy it.
