Bioriented polypropylene, better known as BOPP, has become the film most required by the flexible packaging industry and is gaining ground over rigid plastic given its versatility, economy and sustainability. It is a polypropylene film with a coating that allows it to be heat sealed. Its main feature is the protective barrier it offers to prevent the entry or exit of moisture. Its applications are mainly aimed at the mass market of cookies, snacks, chocolates, alfajores, candies and also labels. BOPP technical evolution BOPP began to be developed in the 1970s when a substantial improvement in optical, mechanical and water vapor barrier properties was achieved compared to traditional polypropylene film .
The evolution in the industrialization of its production allowed costs to be reduced since the first machines of 4 meters wide were moved to those of 6 and today 8 meters are used with a thickness of 20, 18 and 15 microns, which favors high performance per kilogram. “By lowering the thicknesses, you obtain more Telegram Database packaging per kilo, which is something that greatly reduces costs. That is why many companies are choosing to replace rigid plastic containers with flexible BOPP containers, which are also lighter and pollute the environment less,” explains Alberto Zanniello, president of Zanniello SA. Protection and aesthetics The protection or barrier function can be extended, depending on the product, up to six months.
For longer shelf times, BOPP must be combined with other high-tech films such as polyester, polyethylene, aluminum or paper. There are around twenty variants that allow high quality packaging, high protection barrier or special textures to be achieved. However, Zanniello clarifies, this “increases the cost of the product so the need for a combination will depend on the content that must be protected and other characteristics that make this interaction essential.” Different types of BOPP can be found on the market to increase the visual impact of the product and, in the case of metallization, its protective function polypropylene, better known as BOPP, has become the film most required by the flexible packaging industry and is gaining ground over rigid plastic given its versatility, economy and sustainability.
