          Material types of plastic packaging boxes

          2020/5/22 16:28:46

          Plastic packaging is one of the four major materials in the packaging industry: paper product packaging accounts for 30%, plastic accounts for 25%, metal accounts for 25%, and glass accounts for 15%. Blister and plastic boxes are a big category of plastic packaging.

          There are several types of plastics. There are two types of plastics according to their own properties. The first type is thermoplastics whose raw materials can be recycled and reused. The macromolecules of this material are completely disordered. We call them amorphous thermoplastics. Such as PVC, PC, PET, etc. The characteristics of these materials are: good transparency, low mechanical strength, and good flexibility.

          The second type is thermosetting plastic that can only be melted once. It is generally an engineering plastic. It is mainly used for thermal insulation, wear resistance, insulation, high voltage resistance and other plastics used in harsh environments. The most common life is a wok Pot handles and high and low voltage appliances

          The raw materials of blister boxes and plastic boxes are thermoplastics. Thermoplastic packaging products have the following characteristics:

          1. It saves auxiliary materials and is easy to form. The required energy consumption for forming is lower than metal materials such as iron and steel, which saves the material cost. The blister has good sealing performance, light and easy to transport, can pack any special-shaped products, no additional cushioning material is needed for packing; the packaged product is transparent and visible, which meets the requirements of environmentally friendly green packaging;

          And the appearance is beautiful, easy to sell, and suitable for mechanized and automated packaging, which is convenient for modern management, saving manpower and improving efficiency.

          2. The raw materials of blister and plastic box have good chemical resistance, good acid resistance, alkali resistance, and resistance to various organic solvents, and can be placed for a long time without oxidation.
