Are Polypropylene (PP#5) Bags Recyclable? A Guide for Businesses
Yes, polypropylene (PP) bags are recyclable. They just don’t belong in a curbside recycling bin. Woven PP sacks, bulk bags and supersacks are made from a valuable, widely recycled plastic, resin code #5. Once they’re sorted, clean and baled, recyclers buy them and turn them into new plastic products.
The catch is that PP bags need to be segregated and shipped on their own as part of a commercial recycling program, and to not thrown into a roll-off with other plastics. This guide explains which PP bags are most common (like cherry bags or grape bags), what makes them recyclable, how to properly segregate them, and how ensure they’re recycled.
Types of PP bags businesses generate
Most commercial PP bags fall into a few families, and all of them can be recycled when handled correctly.
Bag type | Where it comes from | Recycling notes |
|---|---|---|
Bulk bags, FIBCs and supersacks | Manufacturers, chemical and food ingredient plants, construction, agriculture | High-value when empty and clean. Remove any polyethylene (PE) liner first |
Woven PP sacks (25 to 50 lb) | Animal feed, seed, rice, flour, sugar, fertilizer, pet food | Recyclable once emptied and shaken out. Bags with a laminated or film coating may need to be sorted separately |
Non-woven PP bags | Reusable shopping and promotional bags | Recyclable, but usually lower value because of handles, prints and mixed materials |
Sandbags and erosion-control bags | Construction and landscaping | Often too dirty or UV-degraded to recycle. Ask your recycler first |
Ventilated fruit and vegetable bags (cherry bags, grape bags, cucumber bags, and more) | Fruit packers and growers | When fully PP, these are always recyclable. Check to make sure they aren’t multi-laminate with LDPE or other plastics, though. |
If you aren’t sure what a bag is made of, look for the #5 or “PP” mark printed on it. Woven PP has a visible crosshatch texture and doesn’t stretch the way film does.
Why PP bags get rejected, and what makes them recyclable
PP bags are rejected in curbside programs because sorting facilities aren’t built for them. Bags and sacks wrap around the rotating screens that separate paper from containers, which jams the equipment. So most city programs tell residents and businesses to keep them out of the cart.
Commercial recyclers handle PP bags differently. They collect them separately, already sorted, so there’s nothing to tangle. What decides whether a load gets recycled or rejected comes down to four things:
- Whether it’s single polymer. The load should be PP only. PE liners, plastic film, paper sacks and strapping lower the grade or get the load rejected. Some fruit bags can multi-layered plastic like LDPE/PP laminate, which is difficult to recycle. Check to make sure there is only one plastic number listed on the bag.
- Cleanliness. Bags should be empty, with no leftover product. Small amounts of dust are fine. Caked-on product, soil, food or chemicals are not.
- Condition. Bags left outside for months break down in the sun and become brittle. Fresh, intact bags are worth more.
- What the bag held. Bags that held hazardous chemicals can’t go into a standard recycling stream. Check the original product’s safety data sheet and tell your recycler.
How to prepare PP bags for recycling
A few habits at the dock decide whether your bags earn a rebate or cost you a disposal fee.
- Empty them completely. Shake out or vacuum remaining product. For bulk bags, open the discharge spout fully.
- Pull out the liners. Many bulk bags have a separate PE film liner. Remove it and keep it apart, since PE film is a different grade.
- Sort by type. Keep bulk bags, woven sacks and non-woven bags in separate stacks or gaylords. Separate clear or white bags from printed and colored ones if your volume allows it.
- Store them under cover. Keep bags dry and out of direct sunlight to prevent moisture deductions and UV damage.
- Compact or bale them. If you generate steady volume, a baler compresses them into dense bales that ship for less and sell for more.
Lifting loops, stitching thread and printed labels don’t need to be removed. Recyclers handle those during processing.
What happens to recycled PP
Once your bags leave the dock, they’re graded, baled and sold to processors in the US or overseas. There they’re shredded, washed and melted into PP pellets. Those pellets become new woven bags, plastic lumber, pallets, automotive parts, storage bins and other molded products.
PP bags are a traded commodity, so their value moves with the market. What you’re paid depends on:
- Quality. Clean, single-material, sun-protected bags earn the best price.
- Volume. Full truckloads on a regular schedule beat occasional small loads.
- Preparation. Baled material ships more efficiently than loose bags.
- Market demand. Pricing follows virgin PP resin prices and demand from domestic and export buyers.
Even when the market is soft, recycling PP bags usually costs less than landfilling them. Bulky bags fill dumpsters fast and drive up hauling bills.

Frequently asked questions
Can I put PP bags in my recycling bin? No. Most curbside and commercial single-stream programs don’t accept them because bags jam sorting equipment. Send them to a commercial recycler instead.
Are bulk bags (FIBCs) recyclable? Yes. Empty, clean bulk bags are one of the most valuable PP bag types. Remove any plastic liner before recycling.
Do I need to cut off the lifting loops? No. Loops, stitching and labels are handled during processing.
What about bags that held chemicals? Bags that held hazardous materials need special handling. Share the product’s safety data sheet with your recycler before shipping.
Can I reuse bulk bags instead? Sometimes. Bags rated for multiple trips can be cleaned and reused. Once they’re worn or single-use rated, recycling is the next best option.
How many bags do I need before a pickup makes sense? It depends on your location and what else you recycle. Bags can often ride along with cardboard or other materials on a mixed load, so contact us even if your volume is small.
