  2. 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. [6]

  3. Nalgene - Wikipedia

    en.wikipedia.org/wiki/Nalgene

    The bottle is made from low-density polyethylene (LDPE), and its screw top has two moving parts — a drinking nozzle that seals until snapped open by pulling on it, and a hinged polycarbonate dome, that when closed both snaps the nozzle closed and protects the nozzle against contamination. Unlike traditional Nalgene containers, this item can ...

    en.wikipedia.org/wiki/Multilayered_Packaging

    Multi-layered packaging are multilayer or composite materials using innovative technologies aimed to give barrier properties, strength and storage stability to food items, new materials as well as hazardous materials. [1] Multiple layers are formed by coextrusion, lamination, or various coating technologies. The material of construction of ...

    en.wikipedia.org/wiki/Plastic_bottle

    A plastic bottle of antifreeze Large plastic bottles of water. A plastic bottle is a bottle constructed from high-density or low density plastic. Plastic bottles are typically used to store liquids such as water, soft drinks, motor oil, cooking oil, medicine, shampoo or milk. They range in sizes, from very small bottles to large carboys.

  7. Plastic milk container - Wikipedia

    en.wikipedia.org/wiki/Plastic_milk_container

    Use of food contact materials is required: potential food contamination is prohibited. Strict standards of cleanliness and processing must be followed. The most common material in milk packaging is high density polyethylene (HDPE), recycling code 2. Low density polyethylene (LDPE) and polyester (PET) [1] are also in use.

  8. 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]

  9. Thermoplastic - Wikipedia

    en.wikipedia.org/wiki/Thermoplastic

    Low-density polyethylene (LDPE) is flexible and is used in the manufacture of squeeze bottles, milk jug caps, retail store bags and linear low-density polyethylene (LLDPE) as stretch wrap in transporting and handling boxes of durable goods, and as the common household food covering.
