https://baobitamthanh.com/Lịch sử nhựa và bao bì nhựaHistory of plastic and plastic packagingPlastic or plastic compared to other packaging materials appeared the latest in history. Although invented in the 19th century, at that time, most plastics were used for military and military activities.The First PlasticsStyrene was first distilled from tree sap in 1831. But the style at this time is very brittle and brittle. Germany improved this technique in 1933, and by 1950 foam was available all over the world. As a result, insulation and cushioning materials as well as foam boxes, cups, and trays are widely used in the food industry.Vinyl Chloride, discovered in 1835, was supplied for the development of rubber chemicals. In the packaging industry, vinyl chloride was only used later. The first product was a deodorant spray bottle created in 1947. In 1958, a shrink film was created by mixing Styrene with a synthetic resin. Currently, the packaging for some oils or liquids is still made from vinyl chloride.Another type of plastic was also created during the American Civil War. Due to the shortage of ivory, an American producer offered a $10,000 reward for the substitute material. John Wesley Hyatt and his brother Isaiah Smith Hyatt experimented for many years. The result is a “Cenluloid” resin that cannot be molded but can only be etched, like ivory. The two brothers received a patent for this plastic in 1870.The appearance of clear plasticCellulose Acetate was first derived from wood pulp in 1990 and has been used for photography since 1909. In 1924, DuPont began manufacturing cellophane in New York. However, it was not until the late 1950s that it was applied to the packaging industry. During the period 1924-1960, polyethylene film was distributed exclusively to the military. Since 1933, sheathing has been used for telephone cables. Later, during World War II, they were used for radar cables and medicine coatings.Cellophane films and other clear resins were later improved for coatings. Besides the traditional inner membrane, the membrane can now be dimmed, colored, or patterned.Polyethylene Terephthalate or PET has only been around since the last 20 years of the 20th century. When it appeared, it was used in beer bottles around 1977. By 1980, food and other hot items could also use packaging.
