LDPE is a class of plastics known as polyolefins. It is made under high pressure by polymerizing ethylene. Polymerization is a process of rearrangement of molecules within the atom. Low density polyethenes are flexible and unbreakable. Their thickness can vary. They can be opaque or translucent. Properties LDPE is non reactive at room temperature except for the presence of a certain strong oxidizing agent or any other solvents that may cause swelling. It can withstand a temperature up to 80 �C. It is unbreakable. It has branching and the intermolecular forces within the molecules are less. The tensile strength is least but the resilience is much higher. Its molecules are loosely packed. Density is lower and contains certain chemical elements like hydrogen and carbon. Chemical resistance It has excellent resistive power towards concentrated and dilute alcohols, acids, bases, and esters. It is resistive towards ketones, vegetable oils and aldehydes. It has poor resistance and is not recommended using with halogenated hydrocarbons.
APPLICATIONS: It has several applications in day to day life based on its features. > Strength and flexibility: LDPE is used in several applications. It has resistive power against alcohol, acids etc. so, it can be used with any kind of foodstuffs. It is resistant to varying temperature. It can withstand any kind of chemicals in the laboratory. It can be rolled into thin and flexible sheets and varying shapes. LDPE is used extensively in construction to cover surfaces, or create plastic sheeting barriers.

It also provides resistance against corrosion and can stand a temperature up to -58 degrees to +178 and above. It is mostly preferred in laboratories.
Food and Drink Items: Use LDPE
In our day to day life LDPE is used in food jars and bottles. Several food items like soft drinks, milk, and alcoholic beverages are stored in LDPE containers. Other foods like meat, cheese, bakery, goods, and poultry are wrapped with LDPE sheets and stored properly. It is mostly used where one requires both clarity and strength. About 55 percentage of people over the world use LDPE for packing.
Household Containers as well as Implements
LDPE is also used in home for storing food items. It can be used as a container, trash bags, plastic wraps and garments. It appears in sporting goods, toys, temporary closures for the containers. It can be used as waste buckets as well as household utensils that ranges from dustbins to spatulas. It can be used in case of electrical wires like a coating or mostly insulating the wires. The first use of this was in protecting the cables that are present under the water.
It is also used in industries. It can be used as a coating over the paper container. It can protect liquids and several other substances. It acts like a barrier for the woven cloth as well as paper. It is formed into certain flexible pipes in certain applications as well as in some insulating products.
The best part in using LDPE is, it is completely recyclable. It can be recycled and reformulated into some other plastic films or bags or bottles made of plastic. Sometimes it can also be converted into cloths. It can also be recycled and used to make park benches or nay other outdoor products.
