LDPE LB7000 Plastic Granules Overview
At a time when the packaging material industry is accelerating towards environmental protection, high speed and functionality, LG Chem's LDPE LB7000 has become a strategic raw material for coating applications due to its precise performance and high process adaptability. As an LDPE plastic granules designed for coating, it not only effectively meets the process challenges of high-speed production lines, but also brings the double value of quality improvement and sustainable manufacturing to the packaging industry.
01 | Analysis of Material Highlights
Additive-free design: safer and more environmentally friendly
・No openers or slip enhancers to reduce migration risk and meet food contact grade application requirements.
・Suitable for flexible packaging, agricultural film and other products that require high material purity, in line with the trend of sustainable packaging.
Excellent mechanical and thermal properties
・It has moderate tensile strength and ductility, ensuring that it is not prone to breakage during the coating and coiling processes.
・The internal shrinkage is low, which can maintain the stability of the film layer and improve the consistency of packaging.
・The melting temperature is moderate, the thermal stability is good, and it supports continuous operation of the extrusion coating process.
Excellent coating performance
・LDPE LB7000 plastic granules supports high speed coating processes up to 250m/min, increasing overall productivity.
・Excellent coating uniformity and thickness control to reduce edge waste and improve yield.
・Good adhesion to PET, aluminium foil, paper and other substrates, suitable for heat-seal lamination and laminated structures.
| Performance Aspect | Measured Value | Practical Benefit |
| Velocidad de recubrimiento | Up to 250 m/min | Supports ultra-fast coating; ideal for modern high-speed lines |
| Coating Control | Minimum 13 g/m² | Uniform application; reduces material waste and unit cost |
| Thickness Stability | Excelente | Minimizes film deviation; improves yield |
| Adhesion Performance | Strong | Bonds well with PET, OPP, aluminum foil, etc. |
| Control de contracción | Only 18 mm | Ensures flatness of finished film; enhances post-processing |
02 | Multiple application scenarios: from daily packaging to functional films
LDPE LB7000 plastic granules can be widely used in:
Flexible packaging coating: milk bags, frozen food packaging, liquid condiment bags
Agricultural film: greenhouse film surface layer to enhance durability and light transmission
Paper-plastic composite packaging: e.g. kraft paper bags, paper-aluminium composite bags
Aluminium foil coating: to enhance sealing and barrier properties
Surface protection film: covering film, film layer for industrial component packaging
