What about if I used one to wrap the book and then another to put it in, then ship? Thx** A: As an online seller, I do ship heavy items in these bags, but I double and sometimes triple the bags to ensure they don’t break. Now, I’ve never shipped heavy books, but I’ve slid heavy boxed items in these bags, as I buy various sizes of them, and I’ve shipped heavy bags of clothing weighing almost 20lbs. These bags are pretty sturdy. I think you’d be alright double bagging a heavy book in these. Plus, they look nice. **Q: The price is very attractive, is it easy to tear?** A: I have shipped clothing items and had no complaints about the packaging **Q: Is the a suffocation label on these?** A: No ## Customer Reviews ### ⭐⭐⭐⭐⭐ Nice looking and a great value. *by on Reviewed in the United States 19 April 2026* My second time purchasing the Ucgou poly mailers. A great value for the price. While not the thickest poly mailers I've used, they're also far from being the thinnest and a good sturdy mid-weight. Thus far, no issues with tearing. The self-adhesive strip at the top seals well. Our customers love the color (teal) and they're a size that lends itself to many uses. All in all, a great value. ### ⭐⭐⭐⭐⭐ Tamaño perfecto *by on Reviewed in Mexico 14 October 2022* Es resistente y su tamaño es perfecto ### ⭐⭐⭐⭐ Great for the price but a little thin *by on Reviewed in Canada 5 September 2025* Overall a good price for the amount but I do agree with other reviews that they are a little thin.Not too bad for smaller items since you could pretty much double lay it but I would have expected thicker. ## Frequently Bought Together - UCGOU Poly Mailers 14.5x19 Inch Black 100 Pack Large Shipping Bags #7 Strong Thick Mailing Envelopes Self Sealing Adhesive Waterproof and Tear Proof Boutique Packaging Postal for Clothing - UCGOU Poly Mailers 10x13 Inch Black 200 Pack Shipping Bags #4 Strong Mailing Envelopes Boutique Packaging Postal Self Seal Adhesive Waterproof and Tear Proof Small Business for Clothes Books - UCGOU Poly Mailers 12x15.5 Inch Black 100 Pack Medium Shipping Bags #5 Strong Thick Mailing Envelopes Self Sealing Adhesive Waterproof and Tear Proof Boutique Packaging Postal for Clothing --- ## 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.sn/products/260657085-poly-mailers-14-5x19-inch-black-100-pack-large-shipping](https://www.desertcart.sn/products/260657085-poly-mailers-14-5x19-inch-black-100-pack-large-shipping) --- *Product available on Desertcart Senegal* *Store origin: SN* *Last updated: 2026-08-17*
