How to choose disposable paper cups!

Authentication. When choosing a paper cup, you must pay attention to whether there is a QS certification mark. We all know that paper cups will be coated with a layer of polyethylene waterproof film in order to play the role of water insulation, but some businesses will use recycled polyethylene as a waterproof film in order to reduce costs, this kind of recycled polyethylene is very harmful to the body, so pay attention to whether there is a QS mark when choosing. Because the QS mark is a qualified product inspected by the quality supervision department, and the use of recycled polyethylene as a water barrier film must be a substandard product, so as long as we find the QS mark and enter the certification number on the mark into the national or provincial quality inspection, we can easily see whether the selected goods are qualified goods.

2.Color. In fact, this is the same as "good-looking apples are not necessarily delicious".

Some cups look white and clean on the inside. In fact, this is the effect of adding a large amount of fluorescent brightener. Although the addition of fluorescents will make the cup look very beautiful, a large amount of fluorescents can cause harm to the human body.

It is recommended that when you choose a paper cup, it is best to use a fluorescent lamp to illuminate the wall of the cup, if there is a blue color, it proves that the fluorescent agent exceeds the standard, or consider it again!

3.Cup-shaped. It is understood that high-quality paper cups can ensure that there is no leakage for 72 hours after filling water, and low-quality paper cups may seep water in 30 minutes.

Therefore, when choosing, we need to pay attention to whether its shape is firm and not deformed, if the selected paper cup is deformed after holding water, or even can not be picked up, it is recommended not to choose. Because such paper cups not only affect the use, but also the quality is not very good!

4.Printing. The mouth of the cup should not be printed within 15mm from the cup body and the bottom of the cup within 10mm from the cup body" which is specified in the national GB T 27590-2011 standard.

Because there is no ink that can directly contact food in China. In order to avoid bringing harmful substances on the pattern into the mouth when drinking water, you should pay attention to the position of the printing when choosing!

5.Smell. Some paper cups will emit a very pungent smell due to the poor relationship between the material and the quality of the ink, which will be very bad for the body when used. So when choosing, try to choose paper cups with a soft smell or no smell!

When choosing disposable paper cups, what kind of high-quality paper cups are? Don't make a mistake.

It's best not to use it, if you have to use it, pick a thick and hard one, don't buy the kind that is flat when you touch it.

The capacity of an ordinary disposable cup is generally 220 ml or 180 ml.

This cannot be generalized, and the size and capacity of disposable cups are large and small.

The capacity of the commonly used disposable paper cups is generally 9 ounces of 250 ml or 7 ounces of 180 ml.

Disposable paper cups are generally about 250ml in ordinary packaging.

What is the standard capacity of disposable paper cups? It's hard to say, the standard capacity of disposable paper cups is 220 ml, and the small one is more than 150 ml, which should be measured according to the size of the paper label.

Disposable paper cups are available in different sizes, from 100 milliliters to four or five hundred milliliters.

Generally, most of the ones used at home are about 150 to 250 milliliters, and this problem is not easy to determine.

A common disposable paper cup has a capacity of 250 ml. Generally speaking, most of the ordinary disposable paper cups that can be bought in the supermarket have a capacity of about 250 ml, and the specification is 9 ounces, in addition to the disposable paper cups with capacities of 350 ml, 450 ml, 500 ml and 550 ml.

Precautions: Most of the disposable paper cups are used because there are guests at home, so for this kind of use, you can lose it, plus the layer of glue of the disposable cup is too thin, and then it is generally scalded after high temperature disinfection, and it is not very hygienic if it is not sterilized, but if there is a condition, it can be disinfected by other methods such as ultraviolet rays after rinsing a few times, and then it can be filled with drinks that are not too hot many times.

Disposable cups are common in our lives, but in order to prevent water penetration when producing cups, the inside of disposable cups is usually coated with a thin layer of wax. The heat of the wax will melt. Generally, if the water temperature exceeds 40, this layer of wax will melt away.

Therefore, it is best to use disposable paper cups for cold drinks, rather than hot water above 40.

<> "In daily life, disposable paper cups can be seen both at work and at home, so everyone is no stranger to it. So, do you know what is the use of disposable paper cups at home in addition to drinking water? Do you really use disposable paper cups?

Today, I will share with you 3 hidden uses of disposable paper cups, which are cost-saving and practical, and solve a lot of family troubles. Let's take a look at the hidden uses of disposable paper cups at home!

Purpose 1: Storage.

I believe that most people think that disposable paper cups are only used for drinking water, but in fact, there is a hidden use for putting it in the bathroom. Start by preparing a disposable paper cup. Then use scissors to cut the disposable paper cup in half and divide it in two.

Next, we apply a little hot melt glue to the edge of the cut paper cup and stick it to the bathroom wall. Such a bathroom storage artifact is made. We can put the daily necessities such as toothpaste, toothbrush, and cosmetics on the bathroom sink in disposable paper cups.

Purpose 2: Save water bills.

Generally, when everyone washes their hands after going to the toilet, a large amount of water will be sprayed as soon as they turn on the faucet, but washing their hands does not need so much water, but it will waste water. Even if we think about turning down the faucet later, this gap time is wasted. At this time, disposable paper cups can come in handy if you have them at home.

We just need to cut a faucet-sized hole at the bottom of the paper cup, and then put this disposable paper cup on top of the faucet. This simply cuts a tap-sized hole in the bottom of the paper cup. Then put this disposable paper cup on top of the faucet.

In this way, when you turn on the faucet to wash your hands, the water will be dispersed, and the contact area between the water and the hands will become larger, which shortens the time for washing hands and avoids wasting water, so as to achieve the effect of saving water.

Use 3: Make tea.

It is inevitable that some guests will come to each family, and it will be a bit monotonous if you pour cold and white water directly for the guests, so many families will choose to make tea to entertain guests. However, what should I do if I don't have a tea set to make tea? Even if there is a tea set for making tea, but there are many steps, what should I do if I bend the pins?

Don't be afraid to encounter such a problem, teach you a simple way to make tea. Prepare 2 disposable paper cups first. Then use a toothpick to poke some small holes in the bottom of one of the paper cups.

The next step is more critical. We put the paper cup with the hole poked on top of the other one intact and fold it, and then put in the tea leaves and warm water. After the tea leaves are brewed, slowly lift the paper cup above to let the tea brewed in the paper cup flow into the paper cup below.

This way the tea is not only time-saving and convenient, but it also filters out the tea leaves. Learn this trick, entertain guests with more face, and solve many family problems.

After reading this life trick, are the paper cups at home only used for drinking water? Hurry up and learn that disposable paper cups also have 3 hidden uses, which are money-saving and practical, and solve the troubles of many families. Have you learned the hidden uses of disposable paper cups?

After reading it, hurry up and tell the people around you.

The main difference between disposable paper cups and water temperature cups is their design and purpose.

Disposable paper cups are usually used to hold hot or cold beverages, such as coffee, tea, juice, etc. The material of the paper cup is generally pulp, and the inner coating is often made of plastic materials such as polyethylene or sodium polyvinate, to prevent water leakage. Due to the material, paper cups are not suitable for hot water or grease food, because the high temperature will slide and cause the paper cup to deform, burn or cause water leakage.

The water temperature cup (also known as the thermos cup) is specially designed to isolate the heat conduction between the external environment and the liquid in the cup, so as to achieve the effect of heat preservation or cold insulation. The material of the water temperature cup is generally stainless steel, glass or plastic, etc., and its interior is mostly isolated by a vacuum layer or a gas layer, which can effectively delay the temperature change of the liquid. The water temperature cup is suitable for holding various drinks such as hot water, cold water, tea, coffee, etc., and is often used in home, office, travel and other occasions.

Therefore, the design and purpose of these two cups are different, and they need to be selected according to the actual needs.

The water in the disposable cup will cool quickly, and the water temperature cup can be stored for a day without getting cold.

The general raw materials of disposable paper cups are: food-grade wood pulp paper + food-grade PE film.

Disposable paper cold drink cup is a paper cup that can hold cold drinks, cold drinks have a characteristic, they need to be frozen or refrigerated, and the safe use temperature is 0 -5. It is decided that the paper cup can be waterproof as a whole. The body of the cold drink cup is made of food-grade wood pulp paper + PE film on the inner and outer surfaces.

In this way, it can effectively prevent the pulp paper from losing its stiffness and toughness due to contact with moisture.

In order to achieve the effect of water insulation in the production of paper cups, a layer of polyethylene water barrier film will be applied to the inner wall. Polyethylene is the safest chemical in food processing. However, if the material selected is not good or the processing technology is not up to standard, it may oxidize to carbonyl compounds during the process of hot melting or coating of polyethylene into paper cups.

Carbonyl compounds are not easy to volatilize at room temperature, and they may volatilize when hot water is poured into a paper cup, so people will smell strange.
