2. Plastic extrusion - Wikipedia

   en.wikipedia.org/wiki/Plastic_extrusion

   Blow extrusion of plastic film. The manufacture of plastic film for products such as food packages, shopping bags, and continuous sheeting is achieved using a blown film line. [5] This process is the same as a regular extrusion process up until the die. There are three main types of dies used in this process: annular (or crosshead), spider, and ...

3. Low-density polyethylene - Wikipedia

   en.wikipedia.org/wiki/Low-density_polyethylene

   LDPE has SPI resin ID code 4 Schematic of LDPE branching structure. Low-density polyethylene (LDPE) is a thermoplastic made from the monomer ethylene.It was the first grade of polyethylene, produced in 1933 by John C. Swallow and M.W Perrin who were working for Imperial Chemical Industries (ICI) using a high pressure process via free radical polymerization. [1]

4. Ethylene - Wikipedia

   en.wikipedia.org/wiki/Ethylene

   Polyethylene, also called polyethene and polythene, is the world's most widely used plastic. It is primarily used to make films in packaging , carrier bags and trash liners . Linear alpha-olefins , produced by oligomerization (formation of short-chain molecules) are used as precursors , detergents , plasticisers , synthetic lubricants ...

5. Biodegradable bag - Wikipedia

   en.wikipedia.org/wiki/Biodegradable_bag

   Most bags that are manufactured from plastic are made from corn-based materials, like polylactic acid blends. Biodegradable plastic bags are nowadays as strong and reliable as traditional (mostly polyethylene)-bags. Many bags are also made from paper, organic materials like Manila hemp, or polycaprolactone.

   en.wikipedia.org/wiki/Polyethylene

   It is a polymer, primarily used for packaging (plastic bags, plastic films, geomembranes and containers including bottles, cups, jars, etc.). As of 2017 [update] , over 100 million tonnes of polyethylene resins are being produced annually, accounting for 34% of the total plastics market.

9. High-density polyethylene - Wikipedia

   en.wikipedia.org/wiki/High-density_polyethylene

   HDPE is known for its high strength-to-density ratio. [4] The density of HDPE ranges from 930 to 970 kg/m 3. [5] Although the density of HDPE is only marginally higher than that of low-density polyethylene, HDPE has little branching, giving it stronger intermolecular forces and tensile strength (38 MPa versus 21 MPa) than LDPE.
