LDPE 2420K
Description
LDPE 2420 K, also known as Lupolen 2420K, is a non-additive low-density polyethylene (LDPE) produced by Amir Kabir Petrochemical Company. It is delivered in pellet form and is characterized by several key properties and applications.
- High Processability: LDPE 2420K is designed for easy processing through various manufacturing techniques, including extrusion and molding.
- Optical Clarity: The material exhibits high transparency and gloss, enhancing product visibility and aesthetic appeal in packaging applications.
- Balanced Mechanical Properties: With a tensile modulus of 260 MPa, a density of 0.924 g/cm³, and impressive tensile strength (22 MPa in machine direction), it offers a well-rounded combination of strength and flexibility.
- Good Heat Sealability: This polymer forms strong seals at lower temperatures, ensuring secure packaging closures without compromising integrity.
- Food Packaging Film: Ideal for producing films that require a reliable barrier against moisture and contaminants, maintaining the freshness of food products.
- Hygiene Film: Its high tensile strength and flexibility make it suitable for hygiene products such as diapers and sanitary napkins.
- Shrink Film: Commonly used in packaging applications to secure goods tightly during transportation.
- Surface Protection Film: Protects surfaces from scratches and dust during manufacturing and transit.
- Coatings and Protective Films: These are employed in the automotive and construction sectors for their durability against environmental factors.
The polymer can be processed using several methods:
- Blown film production
- Cast film production
- Extrusion coating
- Injection molding
