Today PE is the most important of all plastic materials. PE are classified into the following main groups:


LDPE: Most important and most commonly used. It is most commonly used to make thin films to make bags.
LDPE is easy to heat and is the cheapest type. In different types of LDPE including sliding and lumping
agents, such as bulk packaging, a low sliding coefficient is required for good luggage handling. Or,
when packing soft goods in a bag, it needs a high slip factor. LDPE is soft and tough. MDPE: Used for thin film or for use where higher hardness or softening temperatures are required than LDPE.
MDPE is slightly more expensive than LDPE.
HDPE: Stronger than the above two types. HDPE can withstand temperatures up to 120oC and so HDPE is used in 
steam sterilized packaging. HDPE can also be cut into narrow strands for weaving. However, we use PP more to
make weave. Different types of PE have some important properties that make them the most suitable packaging material.
PE is very water repellant and very good humidity, which is better when the density of PE is higher.
PE also has very good heat-shrinkability and retains its very low density. It can be used at -50 ° C (-58 ° C).
As the temperature changes, its viscosity changes evenly, so it is easy to handle and change. Physiologically,
there are no disadvantages associated with PE because when it burns, it produces only CO2 and water.
