MFLABEL Full Sheet Sticker Labels, Address Labels, White Matte Label Paper, 8-1/2" x 11" Shipping Labels for Laser & Inkjet Printer (25 Labels, 25 Sheets)

I can't speak to adhering to cardboard but I have used almost my entire first box and I am ordering another and have had zero issues with printing or adhering to envelopes or poly mailers. I believe if you are having issues with ink smudging it's more of a printer issue as I have printed from the laser at work and my inkjet and home with no problems. They don't curl on me, which could be that your fuser is too hot on a laser (sometimes there is a setting to change that or it will automatically when selecting label paper type), or it could be that you are storing them in an area with too much moisture. Great value and I would definitely recommend if using on envelopes or poly mailers.

Multiple Repeat Purchase For This Item. These labels work well for my business needs. When using, I know exactly what my print dimensions need to be set at; I am not sure they would be the same for another label. Always same or next day ship. Prices do fluctuate for this item, sometimes I purchase just because the price is right and I know I will eventually use them.

These are great! I use my Brother MFC-J497DW Inkjet printer and put the setting on BP71 to prevent jams. Works great! They also came with these fragile labels that will be useful for me! The adhesive is good and exactly what I'd expect for a standard label paper. I will probably add a small strip of tape on my plastic polymailers, because I'm paranoid, but these will work great for paper mailers and cardboard boxes! Great price and great product!

I use these for the backs of my fine art prints. They did well with my Canon inkjet printer, reproducing photos and text well. How nice not to have to deal with the rounded corners so typical of these half-page labels. Well done!Pricing is good.

Works great for my business needs. I ship pretty often and these are super simple to use and they print out great. They also peel off to apply to the packages very easily. Stick to boxes and polly bags very well.

Was easy to use in my printer

Perfect for eBay shipping labels!

exactly what I needed

Update November 4, 2021:I bought these again to give them a try since they were still cheap. Unfortunately the quality is worse than the previous version. These came slightly less bent at the corners, but are much thinner (very floppy) than the previous, and with a strange waxy back that picks up lint and residue, almost like it is double-sided release paper.--Original review from March 2021: I bought these for printables and making labels at home. They were very cheap so I thought it would be a great way to make stickers for my daughter and for my planner/journal.1. The label papers are smaller than 8.5" width by about 2mm, and longer than 11" by about 1-2mm.2. The labels arrived bent inside the box packaging they were in. The outerbox was fine, as was the amazon box the package shipped in. There is no reason for the papers to be bent, other than maybe they were shrink-wrapped too tight. All 4 corners, of all the papers, were crunched/bent.3. The ink smudges when printing on this paper (inkjet HP envy). Another paper jammed due to the curled edges.4. There is a weird chemical smell from the papers - not huge but may bother some.5. The paper curls on its own, which may or may not be problematic to you based on what you're using it for.If you are using these papers to make stickers at home, it may just do the job if it doesn't jam in your printer and smudges or off-center cuts don't bother you. If you are using these label papers to sell stickers, please don't - your customers won't be happy with curled, smelly, smudgy stickers.

Unfortunately, this label comes off the box a few minutes after sticking. You will see the ears lifting up. Not to be used for shipping boxes otherwise you might end up label falling off and losing your shipment. I purchased and started using the product already, but I must make sure that I tape the edges of the label to the box, so it doubles the effort and cost.I will look for another brand next time.

These are great for Canada Post shipping labels. My laser printer works perfect with these labels. They stick great, perfect size for full size labels and easy to use. The only downside I can see if that there is no specific label template for this but I use Photoshop to place on my template I created. Otherwise they are fantastic!

I use a HP laser printer basic desktop model. It prints on regular copy paper perfectly always.These labels work, but sometimes it comes out a bit smudged. If you rub it just ever so slightly, the ink comes off. I ran cleaning on my printer, and made sure it prints nicely on regular paper. However, it is still a bit smudged on these labels.Also, sometimes it comes out misaligned. I don’t know if it’s a common thing among these 30up labels from other brands, but I would love it if it can come out aligned and not so easy to smudge.

After seeing this had more than 15,000 reviews and almost at 5-star, I was surprised to find out these do not even stick well and come undone on boxes and paper mailers after several minutes. We were lucky at one point because the post office people told us about a package we dropped off that had no label and they remembered us. So the label came off at some point and either we or they didn't notice. Crisis averted because we run a business.It sticks well on plastic though. Only reason I'm giving this two stars and not one is because it's good for the price (I guess) and it sticks fine on plastic mailers. Anyway, we won't be ordering these again.
