PABCK 100 Pcs 1.57x4.33 inch (Inside Size 1.18x3.94 inch) Coffee Food Storage Heat Sealable 3.34mil Mylar Pure Foil Bag Vacuum Pouch for Sampling Packaging Aluminum Foil Package

Product arrived as advertised

I shined a flashlight through a few of these and didn't see any pinholes. Most other cheap Mylar bags I've used have failed this test.

I grossly overestimated how much liquid this pouch would hold. I could put less than an ounce of water in it and have room on the end to seal it. I’m sure it’s a fine product for whatever it’s intended for.

Perfect size, easy to use. I use this for my skincare samples and it easily stores at least 3 uses of each product. I sealed it once with my cricut easy press and have also used my hair straightener. A little bit of a learning curve but figured it out and have a system down.

These are super easy. I used my hair straightener to seal them, and in a pinch one day...I hate to admit it, I used a lighter then pinched it quickly with my fingers. It WORKED. I was so impressed, I'm now on my 9th set. They're great. Just check your sizing of the INNER and should be good to go. Easy tear tab also. Super fast, great condition.

I used this to create my own on-the-go individual portions of electrolyte powders (Just Ingredients) especially for travel. It can be a little fussy but I used a metal funnel and tapped to ensure the powder was clear of the opening so it would properly seal. I used a sealer for Mylar bags (since I already had one) but I believe instructions say that a vacuum sealer heating element would also work.

The media could not be loaded. I was so looking forward to using these for collagen powders when my husband and I traveled. So I put powder in them and sealed them (or so I thought) with my food saver and when I put them in a larger bag for storage in the suitcase, they poured out. I tried redoing them and sealing them three times meaning I went over that same seal three times and they still did not seal. Do not recommend. I’m returning them.

I like these pouches. These are ideal for my personal use of storing our greens powder for on-the-go. I use my flat iron to seal the open end. Seals well without any leaks. The only problem is it’s hard to figure out which size you need before ordering. I still gave it 5 stars because once I figure out the ideal size it will be perfect
