Excellent Melt Processability and Processing Efficiency: Lotte XL600 features a high melt flow rate (MFR) of 8 g/10 min, which endows it with superb drawability and shear-thinning behavior on high-speed extrusion coating lines, significantly reducing die pressure and maximizing extrusion output.
Superb Draw-Down Capability: This grade supports exceptional micron-level draw-down processing, allowing the minimum coating weight to be controlled down to 12 g/m². It resists melt fracture or web breakage under high-speed drawing, dramatically lowering defect rates.
Excellent Balance of Moisture and Gas Barrier: As an LDPE, its water vapor transmission rate (WVTR) under standard testing conditions is merely 19 g/m²/24 hr, creating an effective moisture-proof barrier that significantly extends the shelf life of packaged contents.
Outstanding Low-Temperature Heat Sealability and Adhesion: With a melting temperature of 104 °C, its lower seal-initiation temperature and broad sealing window ensure high inter-layer bond strength and rapid heat-sealing speeds when compounded with substrates like paperboard, aluminum foil, and BOPP.
Due to its unique rheological characteristics, Lotte Chemical XL600 LDPE is widely utilized in industries that demand strict hygiene, high barrier properties, and precise processing:
Liquid Packaging Board: Used as a non-toxic, moisture-proof inner lining for milk cartons and aseptic juice Tetra Paks, providing excellent liquid containment and reliable heat seals.
Flexible Packaging: Widely applied in the extrusion lamination of pharmaceutical packaging films and snack pouches, serving as a critical intermediate bonding layer or heat-seal layer.
Paper Cup & Plate Coating: Employed in single or double-sided high-speed poly-coating for paper cups and meal boxes, imparting waterproof, greaseproof, and temperature-resistant properties to paper containers.
Heavy-Duty Shipping Sacks: Used for inner lining films of chemical raw material sacks and industrial intermediate bulk bags to enhance overall moisture-proof and tear-resistant rigidity.
Q1: Does Lotte XL600 LDPE require drying prior to processing?
A: Generally, as low-density polyethylene (LDPE) is a non-hygroscopic plastic, it does not require routine drying before extrusion or coating, provided it has been stored properly in a dry, cool, and well-ventilated raw material warehouse. However, if the raw material has been exposed to high humidity or transported over long distances under damp conditions, hopper drying at 65°C – 70°C for 1 – 2 hours is recommended to prevent bubbles or surface imperfections during extrusion.
Q2: What is the core difference between Lotte XL600 and a high-MFR LLDPE (Linear Low-Density Polyethylene) in extrusion coating?
A: The primary difference lies in melt strength and neck-in control. Lotte XL600 is a high-pressure autoclave LDPE containing a large number of long-chain branches (LCB) within its molecular structure. This structure grants it superior melt strength and excellent resistance to web tearing during die extrusion, resulting in minimal neck-in, making it perfectly suited for high-speed web coating. Conversely, LLDPE chains feature short-chain branching, yielding lower melt strength, which easily causes edge instabilities and web breaks during high-speed extrusion coating. Consequently, in coating workflows, LLDPE is typically used only as a secondary blending agent with XL600, whereas XL600 can be run directly as the primary material.
Q3: Does this material comply with international food contact regulations and certifications like RoHS/FDA?
A: Yes. As a flagship resin designed specifically for the packaging industry by Lotte Chemical, Lotte Chemical XL600 complies upon shipment with stringent FDA (U.S. Food and Drug Administration) food contact criteria, the EU RoHS Directive, and REACH regulations. It contains no heavy metals or harmful plasticizers, ensuring it can be safely used in various coating and lamination processes that come into direct contact with food, drinking water, and pharmaceuticals.
