Linear low-density polyethylene, also known as LLDPE, is a copolymer of ethylene. It is a thermoplastic used in the packing industry, plastic bags, plastic wraps, stretch wraps, pouches, covers, flexible tubes, pipes and buckets etc. it is a valuable choice for the production of goods because of its flexibility and tensile strength.
How is LLDPE Material made?
Linear low-density polyethylene(LLDPE) is a polymer of ethylene. A polymer consists of long repeating chains of molecules. In the case of LLDPE, it is formed by the copolymerization of ethylene with longer-chain olefins. As the name suggests, LLDPE is a light molecule and consists of short chains. The density of linear low-density polyethylene is between 0.915 to 0.930 g/cm3. Generally, the production of LLDPE requires low temperature and pressure.
Some Important Properties of LLDPE Material?
- It is very flexible with high tensile strength.
- It has good barrier properties.
- It has a translucent and natural milky color.
- It has excellent chemical resistant properties.
- It can retain strength in film form.
- It is resistant to ultraviolet rays.
What are the Applications of LLDPE?
Linear low-density polyethylene has a wide range of applications due to its versatility. There are many unique properties of LLDPE that make it an ideal choice for many industries. Some of the most common applications of linear low-density polyethylene materials are as follows.

- About 80% of the LLDPE is used in film applications. For instance, food packing films, stretch and non-stretch packing films etc.
- As LLDPE helps to prevent the liquid in containers, therefore it is used in extrusion coating applications. The inner surface of containers is coated with LLDPE. Coating for paper and paperboard packaging is the most common example of LLDPE extrusion coating.
- Food packings need a thin sheet to prevent food from the external environment. As LLDPE is flexible and has good strength, therefore food wraps are made with this material.
- Non-food packings require heavy-duty film such as manufacture and agricultural uses. All these films are made by LLDPE.
- It is also used in household products, kitchen and home fixtures, furniture parts, entertaining products and toys.
- Plastic bags and sheets can also be made with LLDPE.
What Factors Make LLDPE Materials a Perfect Choice?
Here are some crucial factors that make LLDPE a perfect choice for the production of goods.
- Recycling a material can help save our earth’s resources and reduce the cost of products. Recycling also prevents our environment from pollution. LLDPE is a recyclable material, so it can be reused again and again.
- It is highly flexible, which makes it possible to make unbreakable products.
- Being resistant to breaking and the environment, LLDPE is a maintenance free material. You can use it for years with no cost of maintenance.
- LLDPE is stain and chemical-resistant, which makes it a more durable material.
- LLDPE is all in one material with many qualities, such as excellent appearance, good sealing properties, resistant properties, low production cost, and transformation. All these factors make LLDPE stand out from other materials.
