The mass production of plastic began in the early 20th century, with the creation of the first fully synthetic plastic, Bakelite, in 1907. This opened the door for the creation of new polymers and plastics, such as polystyrene, polyvinyl chloride (PVC), polyethylene, and nylon. The First and Second World Wars played a significant role in the advancement of plastic production, as the demand for durable and inexpensive materials increased. During the postwar period, plastic became increasingly popular, being used in various industries, including packaging, automotive, and furniture. However, as plastic waste began to accumulate in the environment, public perception of plastic shifted, and the search for more sustainable alternatives gained momentum.

Bakelite, the first synthetic plastic, was invented in 1907
The mass production of plastic began in the 20th century, dubbed the Plastics Age. The first synthetic plastic, Bakelite, was invented in 1907 by Belgian-American chemist Leo Baekeland.
Bakelite was derived from the reaction between phenol and formaldehyde under heat and pressure, forming a thermosetting resin. Baekeland was searching for a synthetic substitute for shellac, a natural electrical insulator, to meet the needs of the rapidly electrifying United States. Shellac was made from the resin secreted by the East Asian lac bug and was used to insulate electrical cables in the early 20th century.
Bakelite's unique properties, including its electrical and thermal insulation capabilities, durability, heat resistance, and mouldability, made it highly desirable. It could be easily mass-produced and used to create a variety of affordable consumer products, such as telephone casings, saucepan handles, and electrical components. Its dark brown, wood-like appearance also aligned with emerging design trends, including Art Deco.
The commercial success of Bakelite sparked a consumer boom and inspired the development of other synthetic plastics. It marked the beginning of the Polymer Age, where synthetic materials revolutionised industries and everyday life. Bakelite's moulding process offered advantages in speed and efficiency, contributing to its widespread adoption.
The emergence of plastics during the world wars further solidified their prominence. The demand for raw materials during these conflicts accelerated advancements in synthetic chemistry, leading to the creation of silicone and synthetic rubber. Plastics became ubiquitous in households, replacing traditional materials and shaping the modern landscape of consumption and production.

World War I and II drove the mass production of plastics
The mass production of plastics can be traced back to the early 20th century, with the creation of the first fully synthetic plastic, Bakelite, in 1907. However, it was World War I and World War II that significantly drove the industrial production of plastics.
The First World War accelerated advancements in synthetic chemistry, with plastics like polystyrene and polyamide becoming commonplace in households. During this period, the availability of petrochemicals made plastics affordable and easily accessible, marking a shift from traditional materials.
The Second World War further catalysed the mass production of plastics due to the urgent need for durable, lightweight, and inexpensive materials. As the war effort prioritised traditional resources like steel and rubber, plastics filled the gap in consumer goods. Nylon, for instance, was used for parachutes and ropes, while PVC was utilised for canvas tents and water-repellent coatings. The United States invested heavily in the plastics industry, with plastic production increasing by 300% during the war.
The post-war period witnessed a surge in consumer demand for plastic goods, with manufacturers promoting plastic homewares in women's magazines. The industry experienced significant growth between 1946 and 1960, with plastic surpassing aluminium in production. Injection moulding and thermoforming technologies made plastic goods affordable and accessible worldwide.
The legacy of the world wars established plastics as a key building block for post-war recovery, shaping the trajectory of the industry for decades to come.

Plastic manufacturing companies and refineries expanded post-WWII
The mass production of plastic began in the early 20th century, with the first fully synthetic plastic, Bakelite, being pioneered in 1907. The two world wars, particularly the second, accelerated the use and manufacture of plastics. The post-war period saw a rapid expansion of the plastic industry, with plastic manufacturing companies and refineries expanding to meet the growing demand for durable consumer goods.
During World War II, the need for easy-to-produce, durable supplies led to the development of plastics that are still used today. For example, the US Army required all combs issued to servicemen to be made of plastic instead of hard rubber, which was scarce. Plastics were also used in countless other applications during the war, from parachute cords to aircraft components.
The United States invested heavily in plastics during the war, providing over a billion dollars to private companies. This investment led to the expansion of plastic manufacturing companies and the construction of more refineries to turn crude oil into plastic across the country. The wartime industry pioneers set the stage for the post-war expansion of the plastic industry.
In the 1950s and 1960s, the plastic industry became a key building block for post-war recovery, providing new durable products to families. The ever-expanding proliferation of consumer goods, such as cars, washing machines, and radios, created an inflationary culture, and plastic became the material of choice for this expansion. Plastic manufacturing companies and refineries continued to expand to meet the growing demand for plastic products.
The success of the plastic industry can be attributed to its ability to provide affordable, mass-produced goods to consumers. The transformation from traditional materials to synthetic substances was unprecedented in scale and rapidity, with plastics offering advantages in terms of cost and availability compared to natural materials.

Injection-moulding machines enabled mass production of plastic products
The mass production of plastic began in the 20th century, spurred by the First and Second World Wars. The first fully synthetic plastic, Bakelite, was invented in 1907 by Belgian chemist Leo Baekeland. Bakelite was used extensively in the creation of household items, and its mass production made it ideal for bringing new design trends to the masses.
Injection-moulding machines have played a pivotal role in enabling the mass production of plastic products. Injection moulding is a manufacturing technology for producing identical plastic parts, and it is the most common modern method of manufacturing plastic parts. The process involves melting polymer granules and injecting them under pressure into a mould, where the liquid plastic cools and solidifies. The versatility of injection moulding lies in the breadth of design considerations and possibilities, as the material used, the desired shape, and the properties of the moulding machine must all be taken into account.
The first injection moulding press was developed by German chemist Arthur Eichengrün in 1919, and he later patented the injection moulding of plasticised cellulose acetate in 1939. The industry expanded rapidly in the 1940s due to World War II's demand for inexpensive, mass-produced products. Injection moulding was further revolutionised in the mid-1950s with the invention of the reciprocating screw, which addressed issues with uneven heating of the plastic. Today, injection moulding is a market worth over $300 billion, producing more than 5 million metric tons of plastic parts annually.
Injection moulding is widely used in various industries, including automobiles, electronics, medical equipment, and aerospace. It is popular due to its high precision, speed, repeatability, and ability to mass-produce complex shapes. The process is also cost-effective for high-volume production, as it offers a low cost per unit when manufacturing large quantities. The choice of mould material depends on cost and product life cycle considerations, with steel and aluminium being commonly used. Injection moulding has enabled the mass production of plastic products, from car parts and electronic enclosures to toys and kitchen appliances.
