Although the experiment failed, the substance peeled off the cloth in a transparent film, which was a breakthrough.ġ940s: Nylon, acrylic, neoprene, SBR and polyethylene were becoming widespread. This first man-made thermoplastic is still used today for photographic film.ġ891: Rayon was developed by Louis Marie Hilaire Bernigaut which, along with cellophane, were the precursors to the “plastics craze” of the roaring 1920s.ġ907: New York chemist Leo Bakeland created Bakelight, which the military found useful in the production of weapons, as well as for electrical insulators, radios, cups, buttons, false gums and silverware handles.ġ908: Dr Jacques Edwin Brandenberger discovered cellophane by applying liquid viscose to cloth – the aim being to make it waterproof. He presented his finding at the Great International Exhibition in London, but investors lost interest due to the cost of the raw materials.ġ868: John Wesley Hyatt developed celluloid from a mixture of shred tissue paper, nitric acid and sulfuric acid. Inventor of the first man-made plastic, Alexander Parkes, claimed the substance was more versatile than rubber.ġ862: Alexander Parkes invented Parkesine, the first man-made plastic, derived from cellulose. HDPE bottles come in all shapes, sizes and colours. bottles designed to hold industrial chemicals, household cleaners and detergents.non-carbonated beverage bottles, such as those for milk and.The chemical composition of HDPE, pictured below, which is otherwise written as: HDPE ( polyethylene), ethylene C2 H4īecause HDPE has moisture-barrier properties and chemical resistance, it has been found to be a perfect fit for many different bottling applications by organizations such as the American Chemistry Council, for example.Įxamples of the types of HDPE bottles you are likely to come across in daily life include: The translucent nature of HDPE bottles makes it possible for consumers to view the amount of product still inside. HDPE bottles are also lightweight and food-and-beverage safe. Other identifying characteristics, which may cause a producer to specify the use of it rather than any other type of plastic, include the fact that it has a high-density, is taut with a good temperature resistance, all of which relates to its lack of chemical branching, and has an excellent water-vapour barrier. This type of plastic can also be colour matched and is popular in white. While not as clear as Polyethylene Terephthalate (PET) plastic, HDPE bottles and containers can be translucent so that you are still able to see your product inside it.
