25 YEARS ANNIVERSARY 11 PETplanet Insider Vol. 25 No. 05/24 www.petpla.net 1971: The petaloid base The Continental Can Company was granted a patent for the petaloid base in 1971, which made the base cup of the first PET bottles superfluous in the early 1990s. 1991: Introduction of recycled content Coca-Cola became the first to introduce bottles with recycled content, incorporating 25% rPET into new bottles, marking a significant milestone in sustainability. Hoechst Celanese Fibers and Film Group, a division of Hoechst Celanese Corp., developed the process. 2022: Bottled in PET – but let it sparkle Sipa presented the first PET bottle for sparkling wine. The product is capable of running on existing filling lines. As the bottle neck looks just like the glass version, it accepts the classical mushroomshaped cork with its metal cage. The base also looks the same as the original. The design provides a top-load resistance of 3500N. 1973: Invention of biaxially oriented PET bottle Nathaniel Wyeth obtained a patent for the biaxially oriented PET bottle (US Patent 3733309), designed for “bottling liquids under pressure, such as beer, carbonated beverages, or aerosols”. Wyeth’s invention encompassed a method and apparatus for producing a hollow, biaxially oriented, thermoplastic article, involving a two-stage process comprising the compression moulding of a preform followed by the blowing of the reheated and stretched material into a bottle. 1999: PETplanet Insider With the launch of PETplanet Insider, the PET industry finally got its own trade magazine. From the very beginning, the magazine from a family-run publishing house has provided the industry worldwide with news, on-site reports and exclusive insights. 2024: Status quo Promising growth prospects continue to be attributed to developments aimed at reducing the carbon footprint. These include further lightweighting efforts, increasing the proportion of recycled material in bottles and switching from energyintensive hot filling processes to aseptic filling. Whatever the PET market delivers - read all about it in PETplanet Insider! 1975: Coca-Cola’s plastic bottle debut Coca-Cola`s “Easy-Goer” plastic bottle was unveiled at the St Regis Hotel in New York and praised for its lightweight, durability and environmental advantages over glass bottles. Made from acrylonitrile plastic, the FDA banned the bottle in 1977 due to health concerns. 1986: Compression-moulded caps CSI acquired H-C Industries, Inc., a company that had pioneered a patented compression molding process for manufacturing plastic closures. The H-C Wing-Lok closure emerged as the beverage industry’s premier mechanical tamper-evident closure.
