We should pay attention to the safety of packaging
Nowadays, in our daily life, food, daily necessities, etc. use packaging. Packaging adorns our vision, and packaging also facilitates our lives. But how much do we know about packaging knowledge? Do we care about the safety of packaging materials in our lives? In fact, many packaging materials are not what our appearance looks like. In this article, packaging machine and palletizer manufacturers mainly explain the packaging materials and the safety of our daily lives.
Plastic bags are the most common in daily life. Plastic bags are one of the most common packaging materials for us. Among them, packaging food in plastic bags is commonplace, but people often ignore that some plastics are toxic to the human body. The fact is that you can pick up a plastic bag and use it to hold food. Polyvinyl chloride plastics are toxic varieties; polyvinyl chloride resins are non-toxic, but when plasticizers are added with plasticizer dibutyl phthalate or dioctyl phthalate, they are toxic. In addition, some plastic products have added stabilizers, and these added stabilizers are mainly lead stearate, which is also toxic. This lead salt is very easy to precipitate, and it will cause accumulated lead poisoning once it enters the human body, so it is loaded with food When using special food bags, they must not be used indiscriminately, and the following points should be noted during use:
1. When PVC products come into contact with solvents such as ethanol, ethyl ether, lead will precipitate, so it is not suitable to use PVC plastic products to store alcoholic foods.
2. When PVC meets oily food, lead will be dissolved into the food, so it is not suitable for packaging oily food.
3. When the use temperature of PVC plastic is higher than 50℃, HC will slowly precipitate out, this gas is harmful to human health.
4. Waste plastic recycling products, because of the complex source of raw materials, it is inevitable to carry toxic ingredients, and can not be used for food packaging. People use foods packed with polyethylene and polypropylene without additives, and it is reassuring to use them as food bags.
