Recycled LDPE Granules: Types, Properties, and Industrial Applications

Low-Density Polyethylene (LDPE) is a widely used plastic known for its flexibility and chemical resistance. With a growing emphasis on sustainability and plastic recycling, recycled LDPE granules are increasingly used across industries for cost-effective and eco-friendly manufacturing.

Let’s explore the main types of recycled LDPE granules, their characteristics, and the most common applications.

1. Recycled LDPE Film Grade Granules

Description:
Produced from recycled LDPE films such as plastic bags, liners, and packaging wraps. These granules are soft, highly flexible, and perfect for film extrusion.

Uses:

  • Carry bags (non-food grade)

  • Garbage bags

  • Liners for packaging

  • Mulching sheets for agriculture

  • Industrial wrapping film

2. Recycled LDPE Injection Grade Granules

Description:
Sourced from molded LDPE products like caps, lids, and containers. These granules are slightly stiffer than film grade but still flexible.

Uses:

  • Lids and soft caps

  • Flexible containers

  • Injection-molded storage items

  • Toys and molded parts

3. Recycled LDPE Milky/Natural Granules

Description:
Made from clean, sorted light-colored waste. These granules have a milky appearance and can be easily colored using masterbatches. They offer good flow and consistency.

Uses:

  • Semi-transparent films

  • Carry bags

  • Packaging films

  • Flexible molded products

4. Recycled LDPE Colored & Black Granules

Description:
Derived from pre-colored or mixed-color scrap LDPE. Black granules are most common due to the mix of materials and are typically the most affordable.

Uses:

  • Black garbage bags

  • Dust covers

  • Non-critical molded parts

  • Ground sheets for agriculture and construction

5. Blended Recycled LDPE Granules (with LLDPE/HDPE)

Description:
These granules combine LDPE with LLDPE or HDPE to improve strength, stiffness, and reduce excessive stretch. Ideal for moderate load applications.

Uses:

  • Stretch film (non-food)

  • Tarpaulin sheets

  • Canal lining films

  • Industrial packing rolls

Benefits of Using Recycled LDPE Granules

  • ♻️ Environmental sustainability

  • 💸 Cost-effective alternative to virgin plastic

  • 🏭 Flexible use in multiple industries

  • 🔧 Compatible with film extrusion, injection molding, and sheet applications

Additional Tips for Buyers:

  • ✅ Always ask for melt flow index (MFI) details

  • ✅ Check for contamination levels and sorting grade

  • ✅ Prefer natural/milky granules when color consistency is needed

  • ✅ Consider blended options for higher strength or structural needs
