Polypropylene bags, an extensive family of plastic packaging solutions, are made from the powerful material polypropylene. From rugged woven bags to a wide variety of packaging applications in a variety of sectors, PP bags demonstrate their ubiquitous adaptability.

At the heart of this article is an in-depth look at the recycling journey of woven polypropylene bags, from waste to new life. We aim to lift the veil behind this cycle， introducing to you how to recycle polypropylene bags, and explore its environmental significance in reducing plastic pollution and the positive effects of recycling.

Common methods of polypropylene recycling

Reusing PP woven bags

Because PP bags, such as woven bags and container bulk bags are cost-effective, lightweight, tear-resistant and moisture-resistant. They can also be sustainably reused many times after their initial use if there is no major damage.

Recycling PP woven bags

However, if PP woven bags reach the end of their functional life, they should be collected, recycled and reprocessed into new plastic products. Whether you are a plastics producer or a plastics recycler, shredding and pelletizing used PP bags is the most efficient way to do this.

When exploring the environmentally friendly attributes of polypropylene (PP) bags, an encouraging fact emerges: not only do these packaging materials exhibit excellent durability, allowing for reuse,they are also highly recyclable and can be converted into recycled plastic pellets, opening up a new chapter in their life cycle.

Polypropy bags recycling pelletizing steps

  1. Collecting & Sorting. Collect the PP bags from the recycling center and sort out the undesired materials.
  2. Crushing & Shredding. Decrease the materials’ size for enhanced cleaning and drying convenience.
  3. Washing. Remove the grease, dust, and other major impurities.
  4. Drying. Decrease the moisture content to 10%-15%.
  5. Pelletizing. Employ mechanical recycling equipment.
