Frequently Asked Questions (FAQ)

1. What is the difference between LDPE and HDPE film?

The primary difference between LDPE (Low-Density Polyethylene) and HDPE (High-Density Polyethylene) lies in their density, structure, and properties. LDPE is more flexible and has a lower melting point than HDPE, making it easier to mold and process. HDPE is stiffer and more durable but less flexible than LDPE, making it suitable for applications requiring more robust materials.

2. Can LDPE film be recycled?

Yes, LDPE film is recyclable. Many recycling programs accept LDPE, although recycling availability may vary by region. Consumers should check local guidelines to ensure proper disposal and recycling.
