What issues should be paid attention to when choosing food packaging bags?
Food packaging bags are closely related to our lives. With the rapid development of society, the demand for food packaging bags is increasing, and there are more and more types. So what problems should we pay attention to when choosing food packaging bags?
1. The outer packaging of food plastic packaging bags must have a Chinese logo, label the factory name, factory address, product name, and indicate the words "for food" in obvious places. After the products leave the factory, they are accompanied by a product inspection certificate.
2. Plastic packaging bags for food have no smell or smell when they leave the factory. Plastic packaging bags with special smell cannot be used for food packaging. the
3. Colored plastic packaging bags (dark red or black and other colors currently used in the market) cannot be used for food packaging. Because such plastic packaging bags are often made of recycled plastic.
4. Try to choose materials without coating or plating. In modern packaging design, in order to make the packaging more beautiful and corrosion-resistant, a large number of materials with plating are used. This not only brings difficulties to the recycling and reuse of materials after the product is scrapped, but also most of the paint itself is toxic. If people eat these packaged foods, it will cause great harm to people's health. In addition, the coating and plating process has also brought great pollution to the environment. For example, the paint volatilizes toxic solvent gas, and the waste liquid and waste residue pollution containing heavy metals such as chromium are produced during electroplating. Therefore, packaging materials without coating and plating should be used as much as possible. the
5. Due to the non-degradable characteristics of food plastic packaging bags, it will cause environmental pollution. Therefore, when purchasing food, it is best to choose green packaging materials. Paper is currently the most widely used green packaging material. Therefore, it is advisable to choose original paper packaging when purchasing food, and biodegradable plastics are also acceptable.
In the 21st century, with the improvement of people's living standards, in addition to the improvement of the quality of the product itself, the packaging requirements of the product are also getting higher and higher. . In today's pursuit of green, green packaging should be advocated.
