The material of the plastic cup is good, and what material is the best for the plastic cup

No. 5 ppPolypropylene plasticWater bottles are safer.

If you often drink hot water, you can choose PPSU, PA12, these commonly used temperatures are above 120 degrees, and the low-end is PP, which can withstand temperatures above 100, but the commonly used temperature is about 80 °, easy to age, **cheap.

The middle end is the temperature-resistant PCTG, which has high strength and stronger temperature resistance than PP. If you just drink cold water, PC is more cost-effective, but it is easy to precipitate BPA bisphenol A when you just fill it with hot water

Plastic cups are loved by many people because of their changeable shapes, bright colors, and the characteristics of not being afraid of falling, and are very suitable for outdoor users and office workers. Generally speaking, the bottom of the plastic cup has a logo, which is the number on the small triangle, the common one is "05", which means that the material of the cup is PP (polypropylene).

The PP cup has good heat resistance, melting point in 170 172, chemical properties.

It is also relatively stable, except that it can be concentrated sulfuric acid.

In addition to concentrated nitric acid attack, it is relatively stable to various other chemical reagents.

But the problem with ordinary plastic cups is very common. Plastic is a polymer chemical material, when hot water or boiling water is filled with a plastic cup, the polymer is easy to precipitate and dissolve into the water, and it is harmful to human health after drinking.

In addition, there are many pores in the internal microstructure of plastics, which hide dirt, and bacteria will breed if they are not cleaned. Therefore, the selection of plastic cups is very important for the selection of plastic materials, and it is necessary to choose food-grade plastics that meet national standards. That is, PP material.

1.Polypropylene (PP).

Polypropylene is a common plastic cup material with high heat and chemical resistance. It can withstand high temperatures, is not easy to deform, and is suitable for daily use. The polypropylene cup also has good transparency, allowing for a clear display of the beverage in the cup.

In addition, polypropylene material is relatively environmentally friendly and can be used. However, polypropylene cups are relatively brittle and hard and may crack when subjected to severe impacts.

2.Polyethylene (PE).

Polyethylene is a soft and flexible plastic cup material that is commonly found in disposable cups. It has good impact resistance and leak-proof performance, and is easy to use. Polyethylene cups are also relatively environmentally friendly and can be used.

However, polyethylene material is relatively soft, not suitable for carrying high-temperature beverages, and is prone to deformation.

3.Polystyrene (PS).

Polystyrene is a common transparent plastic cup material with good transparency and gloss. It is often used to make transparent cups that clearly display the drink inside. Polystyrene cups are relatively brittle and prone to breakage, so care needs to be taken to avoid violent bumps when using them.

4.Polycarbonate (PC).

Polycarbonate is a high-strength, highly transparent plastic cup material. It is resistant to high temperatures and impacts, and is relatively robust and durable. Polycarbonate cups also have excellent chemical resistance and are less susceptible to changes from chemicals in beverages.

However, polycarbonate materials can release chemicals that are harmful to the human body when exposed to high temperatures for long periods of time, so you need to be careful when choosing polycarbonate cups.

To sum up, different plastic cup materials have their own advantages and disadvantages, and choosing the best material should be based on actual needs and personal preferences. If heat resistance, chemical resistance and high transparency are desired, polypropylene is a better choice; If impact resistance and leak resistance are important, polyethylene is a suitable material; If extreme clarity and gloss are desired, polystyrene is a common option; If strength and durability are required, polycarbonate is a material to consider. No matter which material plastic cup you choose, you should pay attention to the correct use and proper disposal of waste to reduce the negative impact on the environment.

The PP material of the plastic water bottle is better. PP material is also called (polypropylene), PP material is currently the safest plastic cup material, PP cup is non-toxic and tasteless, low density. The processing temperature at the time of production is 180-240, so boiling water will not break it down.

PP has good heat resistance, melting point is 164-170, and the products can be sterilized at a temperature of more than 100 °C; 150 is not deformed without external force.

PP material heat resistance:PP polyester is an amorphous one, its melting point should be above 220, and its heat deflection temperature should be about 121 degrees, but because it is a macromolecular polymer after all, the higher the temperature, the greater the possibility of precipitation of small analytical oligomers, and most of these substances are not conducive to human health, and according to the use of customers, the general boiling water is 100 degrees, so the general plastic cup will not be marked more than 100 degrees.

The PP microwave lunch box is the only plastic box that can be put in the microwave oven and can be reused after careful cleaning. Special attention should be paid to some microwave oven lunch boxes, the box body is indeed made of No. 5 PP, but the box lid is made of No. 1 PE, because PE can not withstand high temperatures, so it cannot be put into the microwave oven with the box. To be on the safe side, remove the lid before placing the container in the microwave.

Summary. Hello, according to the survey, there are the following kinds of plastic cups: the first PPSU material, this is the best material in the current plastic cup, PPSU can withstand 180 degrees of high temperature, but it is more expensive, generally used in infant bottles.

The second tritan material, this is also the one I recommend everyone to use, tritan material, can withstand 100 degrees of high temperature, corrosion resistance and no peculiar smell, and most importantly, it is also relatively affordable. The third PP material, this material can also be filled with hot water, but compared with the Tritan material, the corrosion resistance and drop resistance are still a little worse. The fourth is the PC material, the water cup of this material is relatively cheap, and it is the most common on the market.

The biggest problem with this material is that it cannot be filled with hot water exceeding 80 degrees, otherwise it may produce bisphenol A, and this bisphenol A is a harmful substance to the body, so you must pay attention to it. If possible, it is recommended to choose the first PPSU material plastic cup as much as possible.

Hello, according to the survey, there are several kinds of plastic cups: the first PPSU material, this is the best material in the current plastic water cup reed mold, PPSU can withstand 180 degrees of high temperature, accompanied by the blind but ** is more expensive, generally used in the infant grandson bottle. The second tritan material, this is also the one I recommend everyone to use, tritan material, can withstand 100 degrees of high temperature, corrosion resistance and no peculiar smell, and most importantly, it is also relatively affordable.

The third PP material, this material can also be filled with hot water, but compared with the Tritan material, the corrosion resistance and drop resistance are still a little worse. The fourth is the PC material, the water cup of this material is relatively cheap, and it is the most common on the market. The biggest problem with this material is that it cannot be filled with hot water exceeding 80 degrees, otherwise it may produce bisphenol A, and this bisphenol A is a harmful substance to the body, so you must pay attention to it.

If possible, it is recommended to choose the first PPSU material plastic cup as much as possible.

The correct cleaning method is: first, a new cup, before the first use, it should be heated with baking soda powder and cleaned with burning water, and dried naturally at room temperature. It is necessary to wash the cup by hand for daily cleaning, and do not use a dishwasher or dishdryer to clean the cup.

Third, do not expose yourself to high temperatures in direct sunlight. Fourth, if there is any fall and damage to the cup, it is recommended to stop using it.

The material of high-quality plastic cups should be made of raw materials that are not easy to deform, non-toxic, odorless, high-temperature resistant, wear-resistant, easy to clean, and high transparency, such as polycarbonate (PC), polypropylene (PP) and tritan, etc. Among them, polycarbonate (PC) is a high-performance engineering plastic with high transparency, high hardness, not easy to deform, and excellent performance such as wear resistance, corrosion resistance, and ultraviolet protection, and is widely used in cups, tableware and other fields. Polypropylene (PP) is a common food-grade material, non-toxic, tasteless, high temperature resistance, acid and alkali resistance, and is widely used in plastic furniture, water cups, food packaging and other fields.

Tritan is a new type of material launched by Tosoa Glass Technology in the United States, which is characterized by abrasion resistance, protection against bacteria, and good transparency and high temperature resistance.

In general, the choice of non-toxic, odorless, non-deformable stool teaser, wear-resistant, high-temperature resistant, easy-to-clean high-quality plastic cup material plays an important role in human health and environmental protection. In addition, we should also pay attention to the selection of products from big brands and formal sales channels as much as possible to avoid the unqualified plastic cups produced by some small workshops and poison your health. In addition, after using plastic cups, do not discard them as much as possible, especially in outdoor activities, and pay attention to the classification and ** of garbage to avoid pollution to the environment.

It should be noted that although plastic cups have certain advantages, due to the characteristics of plastic materials, there are problems that are not conducive to environmental protection, such as degradable plastics are difficult to completely reduce the thickness of the bucket and reconcile, so we should also try to control the amount of use when using, encourage environmental awareness and "plastic reduction" actions, promote the use of environmentally friendly materials of cups and tableware, etc., and jointly create a green and low-carbon lifestyle. <>
