LFI 2119

Key Characteristics of  LFI 2119 LDPE: 

1. Flexibility:
   • LFI 2119 LDPE offers outstanding flexibility, making it suitable for products that need to bend, stretch, or conform to various shapes without breaking. It is particularly useful for packaging films, bags, and stretch wraps.
2. Melt Flow Index (MFI):
   • LFI 2119 has a moderate melt flow index (MFI), allowing it to be processed efficiently through standard extrusion and molding processes. This helps create films, containers, and other products with excellent surface quality.
3. Chemical Resistance:
   • LFI 2119 provides resistance to many common chemicals and solvents, making it ideal for applications in environments where exposure to certain chemicals is a concern.
4. Low Density:
   • As a low-density polymer, LFI 2119 is lightweight and offers good impact resistance and tensile strength. Its low density also makes it easier to handle and more cost-effective in terms of transportation.
5. Transparency:
   • This LDPE grade offers good transparency, making it suitable for packaging applications where product visibility is important, such as food and consumer goods packaging.
6. Good Processability:
   • LFI 2119 LDPE can be easily processed using techniques such as extrusion, injection molding, and blow molding, making it a popular choice for the production of films, bags, and containers.
7. Environmental Impact:
   • LFI 2119 is recyclable, which makes it a more sustainable option compared to non-recyclable plastics. While its recycling rate is not as high as other polymers like HDPE, there are increasing efforts to improve its recyclability.

Common Applications of  LFI 2119 LDPE:

• Flexible Packaging: Used extensively in plastic bags, food packaging films, shrink wraps, and stretch films. The excellent flexibility of this material makes it ideal for high-performance, lightweight packaging.
• Injection Molding: LFI 2119 is used in the production of small plastic components such as caps, bottles, containers, and closures through injection molding processes.
• Blown Film Extrusion: It is commonly used in blown film applications to produce films for industrial packaging, agricultural films, and protective wraps.
• Protective Films: LFI 2119 LDPE is often used for protective films in various industries, including agriculture (e.g., greenhouse films) and construction.
• Coatings: Used in coatings for other materials where flexibility, transparency, and chemical resistance are required.

Processing Methods:

1. Extrusion: LFI 2119 can be easily processed through extrusion to produce films, sheets, and other products. Its moderate MFI makes it suitable for both high- and low-speed extrusion processes.
2. Injection Molding: The material can also be used in injection molding processes to produce complex molded parts with good surface quality and dimensional stability.
3. Blow Molding: For hollow products like bottles and containers, LFI 2119 can be used in blow molding processes.

Advantages of LFI 2119 LDPE:

• Low Cost: Due to its lightweight nature and cost-effective production methods, LFI 2119 is often used in large-scale manufacturing, making it a cost-efficient choice for many applications.
• High Durability: It provides good impact resistance, making it durable for use in products that may experience mechanical stress.
• High Flexibility and Pliability: The material’s flexibility makes it ideal for use in applications where bending or stretching is necessary.
• Transparency and Aesthetic Appeal: It can be made into transparent or semi-transparent films, which is particularly useful for applications like food packaging where visibility of the product is essential.
