Packaging materials may cause harm

Then the food packaging materials is how to produce harm to human body health? In the process of contact with the food, the harmful material in the packaging materials will be along with the increase of contact time, gradually moved to within the food, when when eating food and harmful material will enter human body together with food, so as to affect the user's health. Food packaging materials from damage caused by the contact Angle can be divided into direct and indirect contact, also can be divided into frequent contact and casual contact. Accident will happen such as kitchen countertops and food contact; Paper packing food in the heat preservation bags, and thermal insulation bag lining indirect contact will happen. These forms of contact are likely to provide opportunities to the migration of harmful substances. From the perspective of production and processing, the dangers of food packaging can also be divided into two aspects. First, the damage material itself. Most of the packaging material is chemical products, and its material itself exists hidden trouble. Generated when the plastic high temperature cracking of the monomer, for example, may through the packaging such as metal materials in heavy metal transfer into the food. Second, the illegal additives in the process of production. For example, in order to make children tableware color bright at the same time reduce the cost, some unscrupulous traders will use industrial grade masterbatch staining of product, because the harmful material of industrial-grade abound, such as aromatic amine, such as heavy metals, if intake of the body can cause serious consequences. For example, some manufacturers use recycled paper production of food packaging paper, at the same time in order to improve the whiteness of the paper using fluorescent whitening agent, studies have shown that the fluorescent whitening agent into the body greatly increases the risk of human cancer. Possible violations, additives and phthalates, it is a kind of widely used in toys, food packaging materials, medical bags of plasticizer, rubber hose, detergents and other products. Once dissolution and into the human body can produce estrogen-like effects similar to human body, human body endocrine interference, the male reproductive system, increase women's risk of breast cancer, liver kidney meanwhile endangers children, cause children precocious puberty.
