Description
LLDPE 18B04 is a type of linear low-density polyethylene (LLDPE) specifically produced as a film for a wide range of applications, such as cast film, stretch wrap, and as a blend component for wires and cables. Its high flexibility and strength make it the first choice in many sectors.
- Butane-1 (C4) Comonomer: Adding butene-1 as a co-polymer to the base material helps with specific properties, such as tear resistance and clarity of the film.
- Additives: Providing antioxidants, lubricants, and acid scavengers makes the film more durable and processable and has better long-term performance.
- High Melt Flow Rate (MFR): An MFR of 4-5 g/10 min is an indicator of good flow properties, which are very important for the capabilities of the film extrusion process during manufacturing.
- Excellent Elongation and Tensile Strength: With elongation in the range of 950/900% and tensile strength reaching 25/23 MPa, the film can be stretched and pulled without the danger of tearing off.
- High Tear Resistance: Whether along the Machine Direction (MD) or Transverse Direction (TD), measurements for Elmendorf Tear Resistance are both high. Thus, the film is highly difficult to break or puncture, and the protection it offers is reliable.
- Cast Film: The film’s crystal clear and cut-resistant characteristics make it perfect for packaging where visible products and package integrity are the prime concerns.
- Stretch Wrap: LLDPE 18B04 offers a secure and covering wrap for these containers for the items during storage and transportation. It can be stretched to a very high level and shows great strength, so the wind remained tight and did not damage the contents.
- Wires & Cables Blend Component: The film’s features add to the performance of the insulation of wire and cable systems, which are not only electric but also protected from harmful external factors.
- Durability: The film’s toughness, tear resistance, and impact resistance are high, making it last long. This means fewer new films need to be replaced regularly.
- Protection: The film is a very effective defence system against haze, dust, and many other contaminants; therefore, it protects the packed goods.
- Clarity: The film’s high clarity allows customers to identify the product easily. This, in turn, enhances the product’s aesthetics, which will also aid inventory management.
- Flexibility: The film’s flexibility makes it easy to handle and apply in various packaging and wrapping scenarios.
- Cost-Effectiveness: The film’s durability and versatility can save costs by reducing material usage and product damage.
- Packaging Industry: Companies involved in food, consumer goods, and industrial packaging.
- Logistics and Warehousing: Businesses requiring secure and efficient pallet wrapping solutions for transportation and storage.
- Wire and Cable Manufacturers: Manufacturers seeking to enhance the performance and durability of their wire and cable insulation.
