This very popular plastic is one that many different manufacturers use for a number of different products. BOPP is polypropylene, which is essentially flattened stretched. There are around 45 different types of plastic and each one has its own properties and uses, from commercial to residential. Thermoplastics are the plastics that, when heated, do not undergo chemical change in their composition and so can be molded again and again. PP generally has a high melting point, making it particularly suitable for food packaging products that are used in microwaves or cleaned in dishwashers, for example. Different Types of Polypropylene This copolymerization allows this plastic to be used as an engineering plastic that is in a number of different products and uses. Polypropylene is a thermoplastic polymer that is alternately known as polypropene. One of my favorite things about polypropylene? One important classification of plastics is by the permanence or impermanence of their form, or whether they are: thermoplastics or thermosetting polymers. Image Courtesy: 1.
