Designed for durability and moisture resistance, they feature a strong self-adhesive seal and a sleek black opaque lining to protect and elevate your shipments. Perfect for non-fragile items, these eco-friendly mailers reduce carbon footprint by 60% compared to traditional plastics, making them the ideal sustainable choice for forward-thinking businesses. ## Description Product description Review: Perfect! - 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. Review: Great bags - Great bags. Especially love that they are compostable and environmentally friendly. No issues with quality or durability. ## Features - 100% BIODEGRADABLE - Made of PBAT and modified corn starch in accordance with the standards of ASTM 6400, EN13432, BPI and OK COMPOST HOME. This material is BPA-free, non-microplastic and represents a 60% reduction in CO2 emissions compared to traditional plastics. - LEAVE A LASTING IMPRESSION - Your customers will be surprised and relieved to open shipping bags made of plant-based eco materials. Using biodegradable shipping supplies will speak volumes about your sense of social responsibility and the high grade of your brand, and bring you closer to your customers through a good corporate image. This small sustainable effort will bring your brand to the forefront. - STRONG & DURABLE - These biodegradable shipping envelopes are resistant to moisture, water, punctures, and stretching. The adhesive strip is very strong, and the only way to open the packaging envelope is by cutting or destroying them. You can be sure that your parcels will reach your customers in the same state they left you - intact and looking awesome. - CONVENIENT & ECONOMICAL - Simply peel and fold over to seal each package safely and securely. Compared to shipping boxes, this is an affordable (lightweight) and efficient (no tape required) alternative that makes your products feel more branded and like an exciting package you'd want to receive. Featuring a black inner lining, these fully opaque mailing bags help to respect the privacy of your customers. - PERFECT FOR YOUR BUSINESS - Our 2.5 mil compostable poly mailers are unpadded and perfect for sending out non-fragile items such as clothing, shoes, and knitwear.

I'm hoping to calculate shipping costs.** A: About 0.45 oz **Q: Would a 9x9x4 box fit in these mailers?** A: No. These do not open wide enough to hold a 4 inch high box. The 9x9 will fit no problem, but the approximate maximum height would be 2.5 inches. **Q: 2 Questions: Would a 9x6x2 inch box fit in there? Would my thermal label have any issues adhering to the mailer?** A: These mailers are best suited for flat items like pictures or small magazines. I am not entirely sure a 2 inch deep item will fit, but they do have some stretch. So, I am thinking a 9x6x2 will probably fit, but it may be snug. Your thermal label should not have any issues adhering. I do not use these as the outside mailer, I use them as protective sleeves which I think put inside a rigid cardboard mailer. **Q: Se pueden personalizar ??** A: Yes, May I ask how many do you plan to order?

Especially love that they are compostable and environmentally friendly. No issues with quality or durability. ### ⭐⭐⭐⭐⭐ Very thin and fragile *by J***S on May 2, 2024* I shipped a shirt in these and the shirt didn’t make it to the receiver. And empty bag was delivered. Too thin and fragile to ship anything honestly. Was hoping I would love these but unfortunately not. The sides, where they are sealed just rips open when you slide your item inside. The adhesive to seal them is wonderful however. I wouldn’t recommend buying these unfortunately. ## Frequently Bought Together - 10x13 inch Biodegradable Shipping Bags,50 Count Compostable Poly Mailers with Eco Friendly Packaging Envelopes Supplies Mailing Bags - 12x15.5 inch Biodegradable Shipping Bags,50 Count Compostable Poly Mailers with Eco Friendly Packaging Envelopes Supplies Mailing Bags - 6x9 inch Biodegradable Poly Mailers,50 Count Compostable Shipping Bags with Eco Friendly Packaging Envelopes Supplies Mailing Bags --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/238970811-ktob-10x13-inch-biodegradable-shipping-bags-50-count-compostable-poly](https://www.desertcart.us/products/238970811-ktob-10x13-inch-biodegradable-shipping-bags-50-count-compostable-poly) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-07-30*
