[[LDPE (4)]] | [[LDPE (4)]] was the first polyethylene to be produced during the 1930s. [[LDPE (4)]] has good chemical and impact resistance and is easy to fabricate and form<ref name="CURB" />. | ||
[[LDPE (4)]] is a thermoplastic that is created from the monomer ethylene<ref name="exp">[https://www.plasticexpert.co.uk/plastic-recycling/ldpe-recycling-plastic/ Plastic Expert]</ref>.the same as [[HDPE (2)]] with [[LDPE (4)]] having a lower density than [[HDPE (2)]] making it slightly more malleable and not as strong as [[HDPE (2)]]<ref name="EVE">[https://everydayrecycler.com/plastic-numbers-no-4-ldpe/ Everday Recycler]</ref>. LDPE (4) comes in two forms - rigid [[LDPE (4)]] and soft [[LDPE (4)]]; both of which can be recycled<ref name="EVE" />. This type of plastic is often utilised in film applications because it is relatively transparent, as well as being flexible and tough<ref name="exp" />. It is also used to produce some flexible bottles and lids, as well as being used in some cable and wire applications<ref name="exp" />. | |||

[[LDPE (4)]] can be recycled but it is not widely recycled via kerbside collection systems throughout the UK. Check with the [[Local Authority]] to determine if it is collected for recycling in a particular area. | |||
