PACKZON Poly Mailers Shipping Envelopes Self Sealing Bags White 2 mil (12" x 15.5", 200)

These are okay...They get the job done. But so often I end up doubling them because I don't feel like I can trust them not to rip. I expected similar to the white mailers that Amazon uses...these seem to be half the thickness. I use them to ship clothes I sell on Mercari, Poshmark, etc. For the few things I ship each week they are a fine deal. If I were a mass shipper I'd find better quality.

These bags might be the worst poly mailers I've use in 20 years of selling online. They rip so easy I would never put one in the mail without double bagging it. I even had one rip while pulling off the adhesive backing. Kinda defeats the purpose of an inexpensive bag making these double the price as you need to use two.

These are the only kind of mailers I have never received a complaint about. I have had several items come out of the packages during shipping when using the paper type. When they get caught in the post office machinery, they tear easily. These, do not. If you try to tear one of these with your bare hands, good luck! They are tough as nails, and the adhesive strip is permanent.

I sell on eBay and use these bags to pack clothing items. Some bigger items like sweatshirts fit snuggly and have to be pushed in. Compared to other poly bags, these bags 1) loose the strip that covers the adhesive as you try to put an item in and 2) tear easier when you pull the flap to try to close the bag. This might not be a big deal to others but is a huge deal if you are using the bags like I do. I give these bags a 3-4 for the average user but a 1-2 for a reseller.

Very happy with these. No complaints or problems. They were easy to use and made shipping run smoothly.I've purchased these two times now and am still happy with them. They seal firmly and do not come unstuck during shipping. They are easy to write on with permanent markers and you cannot see through them.

These mailers were just what I needed. They are very strong as I use them to mail small heavy metal objects up to 14 oz for my business without any worry of them ripping. I order over 1000 and have used more than 700 now and have not had one damage or messed up bag. I will be ordering more.

I will not buy polymailers from this seller (PACKZON) again. I buy them frequently from various sellers. These mailers rip very easily. The first one I took out the package ripped before I even put the item in it! I’ve had another puncture and several more rip since then. I wasn’t going to leave a review but these are the worst quality bags I’ve ever purchased. The items I’ve shipped using these bags are very small & light weight articles of clothing. I’ve been double bagging them to ensure my customers items arrive intact and dry. Buy a better bag and save yourself the money & hassle. I looked at reviews before purchasing and they were pretty good (4+ stars), so I’m disappointed.

I liked the strength. You cannot see through the bag. Seams would not rip when I pulled and I tried stuffing a bad with some pointed rounded edged things like books. I poked my finger through, but honestly, it took a bit to do it. I didn't just shove it, because that would not be how a poke would happen during delivery, so just put steady pressure until my finger went through. I sealed the bag and tried to rip off the seal. Nope, it wouldn't budge. Now, if you really wanted to get into this bag without scissors, I'm sure you can. But that is not what normal shipping is about. I think it will hold up under normal wear and tear through the postal systems. The measurements were off slightly. 10" was short by 2/16th. Delivery was fast. I will buy these again. I like this bag a little bit better than the ones I bought online from Walmart too.
