Product Struction
LDPE LB7500 Plastic Raw Material Overview
LDPE LB7500 is a food contact grade low-density polyethylene (LDPE) plastic raw material launched by LG Chem, with good flexibility, heat sealing and coating properties. It is suitable for extrusion molding, calendering and coating processes, especially in food packaging, laminating and composite film materials.
This material combines high elongation, stable coating, low density and good heat sealing, and is one of the most cost-effective options in the current LDPE film market.
01 | Applicable Scenarios: From Food Packaging to Efficient Coating
The main applications of LDPE LB7500 include:
Food packaging film: Passed food contact safety certification, especially suitable for fresh packaging, quick-frozen food bags, etc.
Coating products: With high coating speed and stability, it can be used for high-speed coating lines such as paper-plastic composite and aluminum-plastic composite.
Calendered transparent film: Excellent tensile performance, suitable for lightweight film and elastic demand scenarios.
02 | Interpretation of core advantages
Why choose LDPE LB7500? What are its specific advantages?
✅ Food grade certification: can directly contact food and meet the hygiene standards of export packaging.
✅ Strong flexibility and tensile strength: the elongation at break can reach 500%, suitable for a variety of flexible packaging needs.
✅ Excellent coating performance: the maximum coating speed is up to 500m/min, which improves processing efficiency.
✅ Good fluidity: the melt index is 7.2 g/10min, which helps the material to run stably in high-speed equipment.
✅ Dimensional stability: good heat shrinkage, suitable for heat sealing and heat shrinking processing.
03 | Environmental protection and processing consideration
LDPE LB7500 plastic raw material does not contain additives and has good chemical stability and recyclability. In the current context of plastic packaging developing towards environmental protection and efficiency, it provides manufacturers with a solution that balances performance, compliance and sustainability.
