Because in today's world environment is getting worse, people's environmental awareness is also growing, in order to save energy, reduce deforestation, and various countries around the world, especially developed countries attaches great importance to the recycling of waste paper. Although the recycling of waste paper has very important significance for environmental protection, but there are a lot of health and safety hazards, especially to waste or recycled paper as raw materials to produce food packaging material.
In paper material, plasticizer is often a contaminant, widely exists in printing ink, adhesives, coatings and recycled paper, there is confusion endocrine function, and may even activate the activity of cancer cells, has a great harm to human body health. Due to the plasticizer widely exist in atmospheric suspended solids, water environment, soil environment, biological environment and sediment, easy to mix with packaging materials production and processing, resulting in the pollution of packaging materials. Plasticizer major consumption areas in Asia, especially in our country, in recent years, with the rapid development of polymer industry, plasticizer demand and expanding scale, our country has become the world's biggest consumers of plasticizer. Except illegal add plasticizer in food mainly comes from the migration to the food and food packaging materials. Phthalic acid esters (PAEs) is one of the leading plasticizer, global production and consumption account for about 70% of the total consumption of plasticizer, is currently the world within the scope of one of the chemical contaminant that exists widely. Phthalic acid esters in recent years origin material caused by events emerge constantly, phthalic acid ester is a class of research attention. But material of phthalic acid esters at home and abroad research focused on plastic packaging materials, generally for phthalates testing and part of the class material phthalic acid ester material migration behavior, not on a variety of phthalic acid ester material from paper material outward migration research. |
