The new stand up feature is failing to maintain a secure seal in the freezer. I see air inside the bag at several of the markings of this feature which means it is no longer water tight. These bags are not good for liquids and will not likely survive a wash for reuse.

I bought this product and then I put my sandwich in the bag and went to open it on my lunch break, and the seal broke so I had to cut it open very disappointed I have used this product for years and this is the first time this has ever happened. I might have to find another brand at this point. more than half of the bags have done it.

We have been using Ziploc freezer bags (medium and large) for decades. The last few months, they have been leaking raw chicken and meat juices once thawed. We have to put the Ziploc bag into another bag on a plate when thawing. The bags are not placed near any sharp items. We're extremely disappointed and what a mess to clean! The plates have to be sanitized and we wear gloves when handling the raw meat from the leaking bags.

These new improvements make it difficult to open and close

We had been buying these for decades, but in the last 2 years have found that the zip seal tears apart, ie one side rips the sealing strip off the other side, making it useless. Did they outsource the manufacturing to some low cost factory? We have given up after bag after bag failed. Found a "no name" brand that works perfectly and lasts with use after use.

I do not like them anymore. Quality went down a lot. It separate along pink Line and become useless

I've had several of these "Powershield"storage bags w/ blue zip top, where the tab just pops off… I will not buy these again!

These are good quality bags but the box they come in is horrible. You cannot open it without tearing up all the sides and so for the whole time you use the bags you have to deal with this messy torn up floppy mess of a box.

Ziploc used to be my go to. I would never use any other bag. The new perforation underneath the zip area rips out and makes the bags far more fragile. They are no longer great for opening and re-closing. The perforation rips far too easily.

I love the opening to the box. It was easy to open and easy to access. With it being at the top the bags do not fall out of the box. One was east to grasp and I did not get more than one when I grabbed. I used the bag to hold a sandwich. The pictures show there is plenty of extra room for closure. The bread fits perfectly. So it is a great size. I will also use these to hold my lemons that have already been cut to put into my water each day. I prefer a ziplock over a twist and tie everytime.
