joybest 4 X 6 Inch (1000 PCS) Clear Reclosable Zip Poly Plastic Bags - Resealable Lock Seal Zipper Poly Bags for Prints, Office Supplies, Beads, Arts & Crafts

I will be returning these. There are 2 different sizes in the box and most are the smaller size which does NOT fit the patterns in that I bought this for. Horrible product. From zipper to thickness. Nothing listed in this listing is correct

The industry standard for measuring plastic bag thickness is to measure the thickness of a single layer of the bag. In other words, the thickness of the bag is the thickness of the sheet that it is made from. Joybest has claimed that the bags they sold me are 3.15 mil (which would be .00315) because if you measure the two layers of the bag, its .00315. However, they dont even meet their own made-up standard; two layers of the bag measure .00245 (.0017 per layer). I have a supply of bags labeled 2 mil that measure .0027. Theyre over twice as thick as Joybests 3 mil bags. What they have done is advertised a 3 mil bag and then delivered a 1 mil bag. When confronted, instead of offering a refund, or to bill appropriately for 1000 1 mil bag, they came up with this ridiculous defense. Im not going to waste anymore time on this. Its $40 and Ive already spent far to much time on this.

For the money, nor bad, but once I got to using these bags, in about 200 bags Ive run into 3 different types, none of which are the mil in thickness promised, but some, I dont know how many in the bag of the bags, are not Slit open at the top. I have to cut them, and that ends up looking unprofessional. Bad news, defective bags. No consistency. Look elsewhere.

NOT ACCURATE listing - I bought these because the listing says these are “3.15 mil” bags - a Ziplock freezer bag is 2.7 mil and these are NO WHERE NEAR as thick . . . they are no thicker than a standard sandwich bag (about 1.5 mil). I used a “zeroed” (picture #1), proven-accurate digital caliper to measure 8 layers (picture #2) of the plastic film (4 folds of the two layers in the bag) at .013”, making each layer no more than .00163” (1.63 mil). These bags are not strong or adequate to protect the parts I need to bag. If you only need a snack bag and don’t mind buying from a false info listing, these should work - but they are NOT 3.15 mil or heavy duty by any definition!

Only one mil thick Flimsy and worthless.

This is not a 3.5 mil bag. Made from very very poor quality material and quantity is also not 1000.

These bags are very thin.

These bags are great! A little bigger than 5x7, but thats perfect for me.

The baggies are for spore sample syringes and will fit a lot in them.

Save yourself the trouble and buy a different bag. These are so thin you can’t open the ziplock without tearing the top. Maybe 1 in 5 you’ll get open. Absolute terrible quality
