[[LDPE (4)]] ([[wikipedia:Low-density polyethylene|low density polyethylene]]) is a soft, flexible, lightweight plastic material. [[LDPE (4)]] is noted for its low temperature flexibility, toughness, and corrosion resistance<ref name="CURB">[https://www.curbellplastics.com/ResearchSolutions/Materials/LDPE#:~:text=LDPE%20(low%20density%20polyethylene)%20is,%2C%20toughness%2C%20and%20corrosion%20resistance.&text=LDPE%20has%20good%20chemical%20and,easy%20to%20fabricate%20and%20form/ Curbell Plastics]</ref>. It is not suited for applications where stiffness, high temperature resistance and structural strength are required.

[[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 found in a number of different items around the home<ref name="exp"/>:

*Pallet wrap

*Squeezeable bottles i.e. hand cream tubes

*Shrink Wrap

*Plastic film

*Packaging

*Bags and coverings

*Clear plastic bags - frozen food bags, bin liners, household garbage and bakery bags.

[[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.
