Plastic DEHP effects similar to artificial hormones, can harm male fertility and female sexual precocity, high levels for a long time can lead to liver cancer. Because early childhood is in the endocrine system, reproductive system and development period, potential hazards of DEHP for children brings greater.

Fluorescent agent
Scientists ' research showed that fluorescent agent is absorbed by the body, unlike the General chemical composition easy to decompose. Once a fluorescent agent combined with protein in the human body, not easy to remove it, except through the liver enzymes break down, it can be excreted. If the body had a wound, protein binding of fluorescent agents and wound would impede wound healing capacity. Study also found that of fluorescent materials can make the cells mutate, such as fluorescent agent exposure to excess, toxic accumulation in the liver and other vital organs, it could be a potential cancer-causing factors.

Four strokes to distinguish between PVC and PE
For sale on the market of PE and PVC cling film, how people choose? Some experts pointed out that the following four kinds of identification methods:
First, the naked eye. Poor transparency of the PE material, and the colour is white, covered food looks blurred; gloss PVC material looks clear, because there are plasticizers, to light a little light yellow.
Second, by the hand: PE material is soft, but less toughness, tensile fracture after; PVC material toughness, greatly widening the stretch is not broken and easy to stick in hand.

Third, with fire: PE cling film and lit with fire, flames are yellow and burn rapidly, there's a candle burning taste; due to the presence of chlorine and PVC plastic wrap, lit with fire flame is yellow-green, no drops of oil, after leaving the fire will be quenched, and there is a strong, offensive odor.

Finally, water is: due to the different densities of the two, PE cling film is denser than water and will float after immersion in water and PVC cling film density greater than water, would sink in water. (Reporter Gao Wei Huang Jiejing interns).

Industrial distribution and characteristics analysis of plastic products

Plastic products industry, the geography of production and distribution have obvious, its main production area in the Southeast coastal areas. 2010 output of plastic products are distributed as follows: output of plastic products up to 13318.8kt city, Guangdong Province, rose 17.23%, still ranks first; 9155.7kt, Zhejiang Province, rose 16.09%, the second highest; 5071.1kt city, Shandong province, rose 21.56%, ranking third; 4395.0kt of Jiangsu Province, an increase of 13.19%, fourth; 3184.2kt in Liaoning province, an increase of 19.59%, Fifth;
