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

These might bet 1 to 1.5 mils, but definitely not 3.5 mils thick. The seller is selling substandard product passing it off as something more. Ziploc freezer bags are 2.7 mils and these are significantly thinner. The lip to open the bag is extremely narrow compared to any other plastic zip top bag ive handled. Overall, I would not buy again and cant recommend due to the false thickness.

Let me begin by identifying the product. These review id for the 3x5 zipper bags, Shipping and cost are good, however the bags are really bad. I bought this as a way to keep different seed, nuts, spices separate from each other as I seal them inside in a proper Mylar bag for storage. I needed to store 30 small packets. It took over 70 bags to accomplish this. The seals would not align properly, the bag had a bad seam at the top, and the bottom corners would just split. I would complain about the thickness, however It would have been nice to know the right material and thickness (3.5 mill each side). I dont mind a 10% loss on bulk purchases, but a 50% loss is a bit much.

One of the bullet points in the About this item section of the listing says these are 3.15 mil thick. Im not sure why 3.15 and not 3mil but whatever... these arent anywhere close to that! I usually buy 1,000 qty 2mil thick 4x6 poly bags on Amazon but ended up coming across this listing. Same quantity and thicker bags for a couple dollars cheaper than the bags I usually buy? Heck yeah, why not right? Well, the only thing good about these bags as that you save a couple dollars but it ends there. These bags are so much thinner than the usual 2 mil bags I buy. I mean... its NOTICEABLY thinner. Then theres the fact the bags vary in sizes -- MOST are not 4x6. They vary in sizes with most being slightly larger than 4 x , some smaller, some bigger. The real kicker is that a bunch of the bags are not perfectly rectangular... some are so bad looking, I cant explain how bad the quality control is. Im including a photo of what I mean.... The fact that the corner arent square on many of the bags is what compelled me to write this review in the first place. Moreover, the bags are noticeably more wrinkly than the usual 2mi 4x6 poly bags I buy probably because theyre so thin. I would not recommend these bags for anything other than a few small pieces of paper but seriously, spend the extra couple dollars for quality 2 mil bags.

3.1mil? More like 1.3mil... this is thinner than dollar store sandwich bags. Would not recommend

Not actually 3.5mil thick. Maybe 1.5mil. Very thin.

This will be an expensive lesson. They are not at all as advertised. They are not even close to the 3.15 mil they blame and not even close to as heavy as what I need. So basically I threw my money away. Will never buy from this company again.

Not 3 mil. Maybe .3 mil. Thinner than a sandwich bag. inaccurate description

These baggies will work, but they are thin and cheap. They also have a very strong chemical odor. Would not purchase again.

We purchased these but then had to return them as they were the wrong size. We had absolutely no pushback and were able to return for fully refund.

The 3 x 4 bags I received were not three mill. They are about half the thickness of other two mill bags that I have.
