Food packaging is created through the use of a wide variety of plastics and metals, papers, and glass materials. Recycling these products differs from the act of literally reusing them because the recycling process has its own algorithm which includes collecting, sourcing, processing, manufacturing and marketing these products.
A label (as distinct from signage) is a piece of paper, plastic film, cloth, metal, or other material affixed to a container or product, on which is written or printed information or symbols about the product or item. Information printed directly on a container or article can also be considered labelling.
17 Οκτ 2024 · Plastic, polymeric material that has the capability of being molded or shaped. This property of plasticity, often found in combination with other special properties such as low density, low electrical conductivity, transparency, and toughness, allows plastics to be made into a great variety of products.
Most plastic in use today comes from hydrocarbons derived from crude oil, natural gas and coal – fossil fuels. Hydrocarbons are organic compounds (can be aliphatic or aromatic) made up of carbon and hydrogen Aliphatic hydrocarbons have no cyclic benzene rings while the aromatics have benzene rings.
Plastics are made from natural materials such as cellulose, coal, natural gas, salt and crude oil through a polymerisation or polycondensation process.
Plastic history. The first synthetic plastic was made in 1907, when a Belgian named Leo Baekeland invented Bakelite in a lab in New York. Known as ‘The Material of 1,000 Uses’, it was eventually transformed into phones, radios, jewellery, chess sets and more!
