塑料等级(Plastic grade)

Polyester containers do more harm to humans than disposable

plastic.

Dubai, a twelve year old girl, has been cancer for sixteen

months using the same mineral bottle. The general bottle

contains a polyethylene called terephthalate (polyethylene

terephthalate), or PET plastic material, is made of

terephthalic acid (Terephthalic acid) and ethylene glycol

(Ethylene glycol) combined produced polymers. PET plastic has

the characteristics of light, high transparency, impact

resistance, not easy to break. It can also prevent carbon

dioxide gas and keep the soda gas. Therefore, PET plastic is

suitable for packing, especially for carrying water and drinks.

Some scholars believe that the inside is called a

diethylhydroxylamine (ethylhexyl amine) or DEHA potential

carcinogen, with a safe, convenient and economical if you or

because of repeated use, they are a cancer crisis.

In modern life, we come into contact with a wide variety of

plastic products every day, such as plastic shopping bags,

plastic cups, plates, plastic bottles and so on. However, we

may not know that these plastic products are made from resin

of different materials, and different resin material may

precipitate toxic and harmful substances in different

temperature and humidity conditions, it is not safe. So how can

we understand the characteristics of various materials and use

them safely? One solution is to look at the raw materials for

the manufacture of plastic products.

<1> plastic recycling mark

Plastic recycling marks are a triangular symbol, usually at the

bottom of a plastic container. Inside a triangle 1 ~ 7 numbers,

each number represents different materials, so the recovery of

different digital signs to indicate that the product is made

of resin which, if the product is made of several different

logo is said to have originated in the United states. Now, this

method of labeling has been accepted and quoted by many

countries, including our country. In our country, plastic label

marking is not mandatory, some regular large brand enterprises

in order to facilitate the recycling of plastic products, have

recently begun to mark recycling signs. Although this logo is

mainly for recycling, but consumers can also use this logo to

know what plastic material is used and what environment should

be used.

Different materials use different conditions

The small recycling logo at the bottom of a plastic product is

like a small identification card for each plastic container.

They are made of different materials and vary in use.

"01" - - PET (polyethylene terephthalate)

Mineral water bottles and carbonated beverage bottles are made

of this material. The beverage bottle can not be recycled for

hot water. The material is heat-resistant to 70 degrees

centigrade. It is only suitable for holding warm drinks or

frozen drinks. High temperature liquid or heating is easy to

deform, and the harmful substances are dissolved. And,
