Advantages and disadvantages of plastic packaging

The biggest characteristics of plastic packaging materials are light weight and good mechanical properties. For many goods that need to be transported over long distances, they can reduce transportation weight and facilitate transportation.

Plastic materials have very suitable barrier properties and permeability. You must know that in plastic packaging, there are gas barrier packaging. Moisture-proof packaging, waterproof packaging, and a variety of fresh-keeping packaging used to preserve fruits. These are all packages that are extended by plastic packaging to satisfy the respiration of fresh ingredients. Thirdly, the optical performance of plastic packaging is very good. Since plastic packaging materials can be made transparent, when it is made into a packaging container, we can see the contents clearly. This indirect promotion is effective. Very good. What I have to mention here is that plastic packaging materials have good hygienic properties. For those pure polymer resins, plastic packaging is almost non-toxic. When we want to package food, we can rest assured application. Disadvantages of plastic packaging materials: For individual resin monomers, especially monomer polyethylene, when they are selected for the production of plastic packaging materials, if the content is too high, that is, when they reach a certain concentration, they are easy to be The food in the package is absorbed and causes certain harm to the human body. Therefore, for some plastic packaging materials, they are not commonly used in food packaging.
