Product Overview
Lotte Chemical XL600 is a low-density polyethylene (LDPE) resin manufactured by Lotte Chemical, belonging to its general-purpose and coating-grade polyethylene series. The material features a typical branched structure, endowing it with excellent melt strength and heat-sealing performance, while maintaining good flexibility and optical transparency. XL600 is specifically designed for applications requiring high barrier properties and strong adhesion. Its core function lies in providing stable extrusion coating processability and reliable interlayer adhesion. This product is primarily suitable for extrusion coating, cast film, and composite film production processes.

Disclaimer: The technical data provided above is for reference purposes only and is based on typical values provided by the manufacturer. While we strive to ensure the accuracy of this information, actual product performance may vary based on specific processing conditions and testing methods. Please refer to the official Technical Data Sheet (TDS) and Material Safety Data Sheet (MSDS) provided with your order for precise technical specifications and safety guidance.
Logistics & Supply Standards
To ensure supply chain stability, Lotte Chemical XL600 adopts standard industrial packaging specifications, typically in 25kg multi-wall kraft paper bags or composite bags. Jumbo bag options are also available upon customer request. We maintain sufficient standing inventory in major hub warehouses to meet conventional order demands. The average lead time depends on specific trade terms and destinations, typically with dispatch completed within 7-14 business days after order confirmation. Given that this product consists of general chemical pellets (non-hazardous, non-powder), it supports consolidated shipping with other non-incompatible plastic raw materials during logistics transportation to optimize freight costs.
Compliance & Quality Commitment
We are committed to providing fully traceable material solutions that comply with international standards. For Lotte Chemical XL600, we can provide a complete original technical data package, including the original TDS (Technical Data Sheet), MSDS (Material Safety Data Sheet), and COA (Certificate of Analysis). The product follows a strict quality control system during production and complies with mainstream environmental regulations such as REACH and RoHS. Every batch of product has an independent lot tracking system, ensuring full-chain quality traceability from the production line to the end user, meeting the dual compliance standards for both food contact and industrial applications.
Sustainability & ESG
As a polyethylene material, Lotte Chemical XL600 is 100% recyclable, aligning with the fundamental principles of a circular economy. During processing, the material exhibits low volatile organic compound (VOC) emission characteristics, helping to improve the environmental quality of the production workshop and reducing the burden of subsequent exhaust gas treatment. We recommend that users follow local plastic recycling guidelines during the disposal phase and incorporate it into the recycled plastic stream to minimize the environmental footprint. The product is free of halogen and heavy metal additives, meeting the basic entry standards for material safety in current green supply chains.
Frequently Asked Questions (FAQs)
Q1: The Melt Index (MI) of XL600 is 8 g/10min. What specific impact does this have on the extrusion coating process?
A: An MI value of 8 indicates that the material has relatively high fluidity. This means it exhibits excellent draw-down performance during high-temperature, high-speed extrusion coating, allowing it to be easily drawn thin without film breakage. Meanwhile, thanks to the unique long-chain branching structure of LDPE, it can still control the neck-in phenomenon within a reasonable range on high-speed production lines, facilitating uniform coating thickness control.
Q2: How is the Water Vapor Transmission Rate (WVTR) performance of this material? Is it suitable for packaging with high moisture-proofing requirements?
A: According to the test data (ASTM F372), its WVTR is 19 g/m²/24hr. As an LDPE, it inherently possesses excellent water vapor barrier properties. However, in practical applications, the specific barrier effect also depends on the final coating thickness (a minimum of 12 g/m² is recommended) and whether it is laminated with other substrates such as paper or aluminum foil. For extremely high moisture-proofing requirements, multi-layer co-extrusion or composite structure designs are recommended.
Q3: Regarding the processing temperature settings, since the melting temperature is 104°C, what range should the extruder be set to?
A: Although the melting temperature is 104°C, the extrusion coating process typically requires a much higher processing temperature to ensure uniform plasticization and adhesion. It is generally recommended to set the extruder die temperature between 290°C and 320°C (adjustments should be made based on the specific line speed and substrate type). A higher melt temperature helps enhance its anchor coating effect on paper or aluminum foil.
