Best Bulk Envelope Mailers in 2022

Last update: January 15, 2023

Are bags cheaper to ship than boxes?

There is no definitive answer to this question as it depends on a number of factors, including the size and weight of the bag or box, the shipping method, and the destination. In general, however, bags are often cheaper to ship than boxes.

Are bubble mailers free at the post office?

No, bubble mailers are not free at the post office. You can purchase them at most office supply stores or online.

Are Poly mailers bad for the environment?

Poly mailers are made of polyethylene, which is a type of plastic. Plastic is not biodegradable, meaning it can't be broken down by nature. This means that once a poly mailer is used, it will exist in the environment forever. While poly mailers may be convenient for businesses, they are not good for the environment. If you are looking for a more sustainable option, consider using paper mailers.

Are poly mailers cheaper than boxes?

Poly mailers are cheaper than boxes because they weigh less, cost less to ship, and are more durable. Poly mailers are also recyclable, which makes them more environmentally friendly.


Fu Global 100pcs 14.5x19 Inches Poly Mailers Shipping Envelops Boutique Custom Bags Enhanced Durability Multipurpose Shipping Bags Keep Items Safe Protected(Purple) Review:


These held up well and are really sturdy. I enjoy how I can simply fold the product over if it is smaller and it still works perfectly! Love the color and craftsmanship! The only minor inconvenience was that the bag would be damaged if the adhesive part inadvertently fell into a location other than where you intended it to go. Aside from that fantastic stuff, I wholeheartedly endorse it! Without a doubt, I'll place another order.



UCGOU 8.5x12 Inch Purple Poly Bubble Mailers Padded Envelopes Self Seal Mailing Envelopes Bags Pack of 25 Review:


I often conduct business using UCGOU bubble envelopes in a variety of sizes. I've used other, brand-unrelated, identical mailers (purple bubble mailers), and guess what? You'll look back and wish you hadn't "saved" that $0.20 or $0.40 in price differences for the other brands (BELIEVE ME, WITH FU GLOBAL, YOU'RE NOT "SAVING" MONEY).ADHESIVE: When compared to other brands, this brand's adhesive strip is around 0.5" broad and is situated towards the flap's end. A thin foil covering the glue is used to secure it, and it readily peels away to reveal the adhesive. IT WILL NOT UNSTICK WITHOUT VERY NASTY TEARS ONCE STUCK. When you're sealing your shipments, take your time. I am very confident in the security of this glue while in transit because of how strong it is.DESIGN: The bubbles are flush with the outside of the purple outer plastic, which feels thick to the touch. Because the inside is lined with an additional layer of impermeable plastic, stuffing the mailers is also incredibly simple.It is a great design decision to place the glue closer to the flap's end because it enables you to fill the mailer to capacity while still achieving a complete closure.(Other brands, like Fu Global, employ an adhesive strip that is much thinner and located farther away from the flap end. In their situation, you cannot fill completely and close the container. I was not at all comfortable with the security of it, even with a perfect seal. I felt I had to use more packing tape to secure every package flap, which was a waste of time, money, and resources.)COLOR: I've used countless UCGOU bubble mailers in all sizes, and the color is vivid, evenly-toned, and incredibly well-saturated. Additionally, color is very constant throughout all sizes.TL;DR:Save yourself the trouble, the time, and the idea that you'll "save" $0.25 by switching to a "better deal" brand. The true deal is this. I've tried other manufacturers, but UCGOU offers the highest quality bubble mailers at the best price, hands down.



Fu Global 50pcs 6x10 inches Purple Bubble Mailer #0 Self Seal Padded Envelopes (Useful Size 6x9) Review:


I always buy packaging from FU Global. It is wonderfully padded, robust, and durable. I want everything to be properly protected from handling during delivery because I sell handmade jewelry. These work well for the price, and I've never heard someone complain that they arrived damaged. The glue strip holds throughout shipping since it is sturdy. I adore the colors since they will undoubtedly perk up someone's mailbox.

iMBAPrice Poly Mailers Shipping Envelopes Bags, 10 x 13 - inches , 100 Bags (White) Review:


According to some enjoyable testing I did—since they are so cheap (I spent $9.99 for 100), why not?—they are in fact reliable and waterproof. I could not, under any circumstances, rip one with my hands. The bag then resisted my attempts to further rip it with scissors after I had first attempted to cut it with them. Second, I filled it with water and let it settle; no water leaked. Third, I placed a weight inside a different bag before submerging it in water, but no water entered. If I want to make anything completely waterproof before mailing it, I just wrap the seal with plastic sealing tape one more time because the only way water could enter is if it wiggled through the seal. Lastly, writing Picture: The early results are shown on the left. What was left after two minutes of waiting and smudging with a dry paper towel is seen on the right. The Flair pen didn't work at all (just made little dots), and it vanished when smudged. Sharpie worked, but when it was touched, it virtually vanished. The ballpoint (Uniball) pen was functional and did not smear. My Avery labels, however, were quite simple to remove off the bags. I usually use plastic sealing tape over my addressing for that purpose because I never write addresses directly on any packaging or on a label without a moisture barrier because it's so easy to smudge if the box gets wet. As long as no corner protruded, plastic sealing tape was entirely adhered to the bags and was impossible to tear off. I'm therefore ecstatic about the "bulletproof" nature of these bags. I especially value how tiny they are and how little drawer space they occupy.



UCGOU 10.5x16 Inch Poly Bubble Mailer Blue Self Seal Padded Envelopes Waterproof and Tear-Proof Postal Bags Pack of 25 Review:


I bought these to use for my eBay shop, and so far they are working great (no one has complained about their products arriving damaged or anything), but after mailing a larger item (a book) in one of them, I do have a little bit of anxiety. The package was heavier when I took it up after it was prepared for mailing, so I had to hold onto it firmly. The bubbles started popping, much to my amazement. That has NEVER happened with any of my other bubble mailers, either. In fact, I tried really hard to pop a couple of my ebay-branded ones, and they just wouldn't, proving that the popping was not caused by the addition of a larger object. Do I believe that this is the biggest deal ever made? No. The mailers remain my favorite. The hue is vivid. They are large and lovely. They firmly seal one another. I'm not concerned about the seams coming apart in transit because they seem strong. Nevertheless, I don't believe the bubbles should be popping so quickly, and this is something to keep in mind. I would anticipate that the bubbles would remain intact if I were paying for a bubble mailer. After all of that, I think I would buy these again. I might not send bulkier products in them once more.

10 EcoSwift 19 x 24 White Poly Mailers Size #8 Self Sealing Bulk Packaging Materials Shipping Supplies Envelopes Bags 19 inches by 24 inches Review:


The white shipping bags that Amazon occasionally uses to transport orders are oversized versions of these. It would be perfect for transporting clothes because it can hold a lot of goods or multiple huge items. Its ability to self-seal is a good addition because, once sealed, you can't open it without ripping it. These do not have a "quick open" feature, but I didn't mind because I wasn't searching for it. Overall, I'd say go for it. Blessings!



Sales4Less #2 Poly Bubble Mailers 8.5X12 Inches Padded Envelope Mailer Waterproof Pack of 100 Review:


These bubble mailers are lovely. Strong and durable, with a peel latch that can be opened after it is closed. The seal is sturdy, unlike some other manufacturers' which are more flimsy. The defense against bubbles is strong. From now on, "Sales4less" will be my go-to vendor. Every month, we utilize roughly 500 bags. Outstanding items! Valuemailers used to be my go-to retailer, but they messed up my order and complicated the process overall. You never know what kind of bags you are going to get, in addition to the fact that they sent the wrong bags.
