The properties and uses of polyethylene film we will learn about in detail, Polyethylene is a type of healthy plastic that is used in many different products around the world. Because many people may not know enough information about it and its uses and features, So follow us to know the details.

What is polyethylene?

Polyethylene is an oil-based plastic material. This material is thermoplastic, and more than 60 million tons of this material are produced annually around the world.

• This material is a polymer consisting of a group of long chains symbolized by the symbol PE, some of which are made of PP, and some of which are made of polystyrene (PS).
• This substance was first discovered by the German chemist Hans von Bechmann, who prepared this substance by chance. When diazomethane is heated, it decomposes the white, waxy substance.
• This material was launched practically in 1934 AD, which is affiliated with the British company Imperial. The start of production was 5 years later, as World War II was about to end.
• In the early fifties, the German chemist Karl Ziegler prepared it through organic-mineral mediators with a high degree of selection and higher degrees of crystallinity, which gives a higher degree of density and melting.

Properties of polyethylene film

Polyethylene has characteristics that distinguish it:

• It is a low-density material that can resist thermal change depending on the degree of crystallinity.
• It is also one of the components with good stability in electrical insulation up to 1018 ohms/cm.
• Also it is a material that has low water absorption.
• Non-combustible.
• It is insoluble at room temperature.
• This material is made primarily from oil or natural gas. It is one of the chemical compounds that undergoes thermal plasticization and is subject to change.
• Polyethylene can be easily melted and shaped as desired. Therefore, it is used in many industries.
• The natural form of this substance is transparent and pure, tending to white, especially if the percentage of crystals present in it increases.
• It is used in plastic containers, plastic wraps, And the bags.
• It decomposes when exposed to ultraviolet rays.
• An amount of carbon powder is added to it at a rate of between 2% and 3%.

Types of polyethylene

The type of polyethylene varies depending on the degree of density as follows:

Low Density Polyethylene (LDPE):

This material is flexible and therefore easily shaped. It is used in plastic packaging such as shopping bags.

This material is highly ductile and strong and tends to expand when subjected to tension.

Linear Low Density Polyethylene (LLDPE)

This material is characterized by changing the properties of LLDPE, which occurs by modifying the components of the formula. It has the ability to consume less energy than low-density polyethylene (LDPE).

High-density polyethylene (HDPE)

This material is a type of strong, high-density, moderate-hard plastic. It crystallizes quickly, It is widely used in milk cartons, waste bins, and cutting boards.

Ultra high molecular weight polyethylene (UHMW)

This version of the dense version of partial weight polyethylene, This material can be spun into strong threads several times larger than steel.

This tool is used in bulletproof vests, Therefore, it is weaker than steel and requires greater tensile strength to form it.

Advantages of using polyethylene rolls and bags

The use of products made of polyethylene has many advantages, including:

• This material provides a plastic film over polyethylene, provides excellent protection and resists water leakage. It is a great material for welding. The product can be secured with tight welding.
• Polyethylene is a low-density, puncture-resistant and highly transparent material. shrinkable, With high flexibility, So it can be formed easily.
• It is one of the most adaptable materials, They can be designed in different shades and colors with different thickness and clarity.

Thus, we learned about the properties and uses of polyethylene film, which is an environmentally friendly material that is characterized by its versatility. This is why we rely on it on the oliatra website in the manufacture of polyethylene films.
