Uniform branches with only a few short side chains with a density between 0.87 g/cm³ and 0.93 g/cm³ ("LLD" stands for "linear low density")
It is a soft polyethylene that is produced under high pressure. It combines properties of LDPE and HDPE and is therefore an intermediate form of these two types of PE. It is mainly used for the production of stretch film. It's very tough, dimensionally stable and has extreme puncture resistance. Other properties are very good weather and moisture resistance as well as extreme elasticity and tear resistance. The film is a little milkier than LDPE, for example. It can be processed into very thin foils and can be colored very easily.
LLDPE does not have its own recycling code and therefore no sign is printed on these films. In contrast to other PE films, LLDPE is very difficult to print on. We only process it as a mixed film in order to improve the film properties according to customer requirements.
LLDPE is resistant to water, diluted acids, alkalis, solutions of inorganic substances, solvents, alcohols, aliphatic hydrocarbons, petrol.
LDPE is not resistant to strong acids and oxidizing agents, oxidizing acids, esters, ketones and aromatic and chlorinated hydrocarbons.
