Ethylene polymers are thermoplastic polymers that are used in the production of various packaging materials. These polymers (especially those mentioned below) generally have great resistance to alcohols, oils grease and dilute acids and alkalis.Below is a description of a few of the common ethylene polymers used in various forms, especially for the packaging of perishable consumer items (foodstuff and pharmaceuticals). Get more information about the construction of roads and how thermoplastic is used in it on Thermoplastic Resistant To Traffic (which is also known as ทนต่อการจราจรของเทอร์โม in the Thai Language).

  • Ethylene Vinyl Alcohol Copolymer

This is an official copolymer of ethylene and vinyl alcohol. It is used as a top barrier material to gases (O2 and CO2) but is a very low moisture vapor barrier material. These properties decrease in a humid atmosphere. This can be expensive packaging material. EVA is used primarily as a conductive substance in packaging cartons e.g. for electronics etc..

  • High-Density Polyethylene
  • HDPE is a polyethylene thermoplastic made from oil. It’s Semi-rigid, translucent, very tough, and also has low water absorption. HDPE has moderate barrier properties but isn’t suitable for use at high temperatures.
  • LDPE is a thermoplastic made from oil. It’s very tough but flexible, waxy, moisture/ weather-proof, has the fantastic low-temperature toughness and is easy to process by most methods at low cost and has good general resistance and medium barrier properties.
