Polypropylene bags packaging guide
Polypropylene bags are crystal clear, tough and their superior clarity makes them ideal for displaying and protecting many products.
Polypropylene bags are made using the thermoplastic addition polymer, polypropylene. Polypropylene bags are constructed so they can easily be recycled due to the number '5' as its resin identification code. Polypropylene is also biodegradable and will never accumulate if thrown in the garbage. These bags undergo a chain reaction which degrades them in the presence of sunlight.
Polypropylene bags can be used for promotional use. Though these bags are less dense in comparison to LDPE (low-density polyethylene), their chemical composition makes it feel stronger and stiffer.
Polypropylene is heat resistant, which means it will not get softened at high temperatures. Users can easily put the hot material in them.

- Polypropylene is the most widely accepted commercial archival storage material.
- The polypropylene used in our polypropylene bags is naturally acid free and lignin free.
- Polypropylene bags are made of 100% virgin ultra clear polypropylene plastic.
- Biaxially oriented polypropylene (BOP) plastic is used for the re-sealable lip and tape.
- BOP offers an even higher grade of clarity and is resistant to tears and wrinkles.
- Modern waste management facilities now accept polypropylene for recycling.
- Please check with your local recycler regarding proper separation and identification of materials.
- Yes, the adhesive used on our standard lip and tape bags is similar to "Post-It Notes".
- No, old fashioned polypropylene bags made from cellulose (a wood product) turn yellow with age.
- Polypropylene bags are made from very stable and non-reactive material with no hazardous decomposition characteristics.
