Inkjet printer identification for paper packaging_identification consumables
Filter paper for tea bags, paper bags for bread, paper boxes for fast food restaurants containing French fries and chicken wings, disposable paper cups for entertaining guests at home... In our daily life, food packaging paper products can be seen everywhere. Inkjet printers have been widely used to print information on paper packaging. They can not only guarantee the quality of products circulating on the market, but also safeguard consumers' right to know. However, for the materials used for disposable packaging on the market, the inkjet printer cannot print product information specifically, but consumers should pay attention to the material information. Inferior paper cups generally have impurities on the surface. The cups are very soft, tear them lightly, and emit a pungent ink smell. Don't think that paper cups are disposable products and ignore safety issues. Products that are not of good quality can cause serious harm to the human body. First, check whether the production license number is marked on the packaging of the paper cup; second, carefully check whether the product name, manufacturer’s name, site, product implementation standards, production date, shelf life, sanitation license, etc. are marked on the packaging label. The content that must be marked is stipulated. If the marking content is incomplete or irregular, it is best not to buy it. Some disposable paper cups are abnormally white, which may be caused by brighteners. This is because some inferior paper cups are made of recycled paper. Some companies will add brighteners in order to make the paper white. It is harmful to human health. Therefore, do not buy disposable paper cups that are too white in color. In addition, if the cup is facing the light with impurities, it is best not to buy it. If the paper cup smells pungent, it may contain carbonyl compounds that are not good for human health, and citizens should not buy it. There are also some disposable paper cups that are packaged in splendid fashion, and there are beautiful patterns on the walls of the cups, which are probably printed with ink. If the paper cup smells of ink, it is best not to buy it because the ink contains heavy metals that are harmful to the body.
