Plasticizer is one of the largest plastic additives in world production and consumption. In recent years, China has become the largest producer and consumer of Plasticizers in Asia.
With the improvement of environmental awareness in various countries, pharmaceutical and food packaging, daily necessities, toys and other plastic products on the main plasticizer DOP, such as the proposed higher purity and health requirements, but at present domestic enterprises production of the main plasticizer in many properties, especially health, low toxicity, etc. are difficult to meet the requirements of environmental protection.
The European Union and Russia have found in Chinese plastic toys imported from China found in some plastic toys containing toxic polyvinyl chloride plasticized N-phthalic acid bis (DINP) and phthalic acid diethyl ester (DEHP, or DOP). The 1982 authoritative National Cancer Institute (IARC) conducted a bioassay of the carcinogenicity of DOP, ' the conclusion is that DOP is a carcinogen in rats and mice that can cause cancer in the liver of the gnawing animal. As a result, the poison I born of Dop has attracted global attention.
Although there is still debate about whether cancer can be carcinogenic, countries have taken appropriate measures because of their potential carcinogenic suspicion. China's PVC film in the allowable use of the 10 main plasticizer, the first is adipic acid (ie, deha, short for DOA), the following three for phthalates, DOP, DIOP, their toxicity are relative to the Deha, due to high DOA production costs,
Therefore, the domestic production of PVC film manufacturers most use DOP, DBP-based plasticizer, such as the production of fresh-keeping film, especially in high fat meat products, or use it to wrap food in the microwave oven heating, its plasticizer migration into the package of food opportunities will be more, to human health cause potential harm. In China, has been eliminated by the foreign plasticizers such as DOP Market, and plasticizer manufacturers of non-toxic new plasticizer development and promotion did not cause enough attention. 80% of the domestic market plasticizers are DOP, DBP (dibutyl phthalate) and other plasticizers, low price is the most critical factor.
National standards for food containers, packaging materials with additives to make Chuan sanitary standard "DOP is also listed as one of the plasticizer varieties for food packaging.
