10x13 inch Biodegradable Shipping Bags,50 Count Compostable Poly Mailers with Eco Friendly Packaging Envelopes Supplies Mailing Bags

This is my second time buying these and figured it's time to review. Pros: This size is perfect for shipping many different items, the bags are durable (no complaints from customers like other eco friendly mailers I've tried). Adhesive strips stick well and stay closed. Cons: The first pack I bought had started to discolour upon arrival, perhaps from exposure to moisture? It didn't cause any problems, but it wasn't great looking if you are using them to ship product to customers. Overall I love these mailers and will continue to use them for my small business.

Great bags. Especially love that they are compostable and environmentally friendly. No issues with quality or durability.

Shipping was quick. I use these to mail out clothing I sell second hand and enjoy the simplicity and ease of using these mailers. The quality is great and the fact that they are 100% compostable makes it that much better! The sleek black color is perfect.

It started as an ordinary day, packaging up items to send across the country. But as I held the 10x13 inch Biodegradable Shipping Bags in my hands, I realized these weren’t just mailers—they were a game changer. Each sleek, eco-friendly envelope seemed to whisper a promise: "I’ll keep your items safe, but I’ll vanish when my job is done." Compostable and tough, these bags handled the chaos of shipping with grace. Rain? No problem. Rough handling? Not a scratch. But the true suspense came when I sealed each one shut. Would they protect? Would they endure? Each time, they delivered on their promise, leaving recipients impressed and the planet just a little less burdened. If you’re ready to revolutionize your shipping game, beware: these bags will have you questioning how you ever shipped without them.

Amazing bags. I didn’t use them all. The one I use, felt very good quality and products arrived in good shape. It sealed really good.

Love these! Make sure to keep them out of the humidity, though, because they do start to get discolored if wet.

I’ve been buying these consistently for at least a year now and have shipped thousands of items in them. Occasionally, I’d get a batch with some powdery stuff on it. I think this is a manufacturing thing to ensure the bags don’t start composting before use, but I could be wrong. The adhesive works just fine. I’ve never had a customer report a bag ripped at the seams! I wish there was a 4x6 size available—please make this!

These envelopes do a great job protecting your product from weather, but do not contribute to trash because they are biodegradable. They fit small brochures or magazines very nicely. They do not expand much, so you can only mail items up to a certain thickness. If the cover of your product has sharp edges, you can tear the mailer (I use them for small magazines). But, if you are careful, you will not have any issues. The only thing I do not like about these is the thin plastic film that covers the adhesive! It is such thin plastic that the film sticks to your hand, so you spend some quality time trying to disconnect from that stupid film! But, that has not been problematic enough for me to drop the rating.
