- Latex (pl. latices)
- A water emulsion of a synthetic rubber or plastic obtained by polymerisation and used especially in coatings, paints and adhesives. Latices include a binder dispersed in the water and form films by fusion of the plastic particles as the water evaporates. Properties of these films, such as hardness, flexibility, toughness, adhesion, colour retention, and resistance to chemicals, depend on the composition of the plastic.

- Linear low-density polyethylene (LLDPE)
- A plastic that is used predominantly in film applications due to its toughness, flexibility and relative transparency. LLDPE is the preferred resin for injection moulding because of its superior toughness and is used in items such as grocery bags and garbage bags.
- Liquid Petroleum Gas (LPG)
- Ethane, ethylene, propane, propylene, normal butane, butylene, and isobutane produced at refineries or natural gas processing plants, including plants that fractionate new natural gas plant liquids.

- Low-density polyethylene (LDPE)
- A plastic that is used predominantly in film applications due to its toughness, flexibility and relative transparency. Typically, LDPE is used to manufacture flexible films such as those used for plastic retail bags and garment dry cleaning and grocery bags. LDPE is also used to manufacture some flexible lids and bottles, and it is widely used in wire and cable applications for its stable electrical properties and processing characteristics.
