Does anyone know what can be used instead of zip top bags?

I have trouble resealing some of those bags that frozen food comes in . I roll the top
over a couple of times and put an old fashioned wooden clothesline clip with the metal spring to keep it closed . These are easier than chip clips . I use them on chip bags, the bags inside the cereal box, my Pepperidge Farm cookie bags etc . I love my wooden clothesline clips . I keep a pretty bowl of my wooden clips on the counter .
You can buy 100 of them on Amazon for a few dollars . They sometimes break , but 100 pack lasts me years .

Get the ones with the sliders. Very easy to open and close. Or use a plastic tub. You can buy a case at Walmart

A bowl with aluminum foil over it. Or, they make these shower cap type things to use as covers over bowls.

It'll be difficult to freeze foods using these methods, however, so maybe mom can buy fresh foods in smaller amounts.

Is she able to use the zipper type bags , with the little plastic piece that slides , as opposed to the ziplock where you have to line up the grooves ?
Maybe she could use this for food she makes , leftovers for the freezer .

My mom just uses a bowl and puts a plate on top, a plate that fits snuggly, but mostly for refrigerator left overs

Check out the Ableware 753600000 One Handed Canister Set (Pack of 3) available on Amazon. Ziploc twist n loc containers might work for her too.

If you put the items in containers, here are great silicone lid products I found:

I first saw these at our local Mast General Store and bought several for Christmas gifts.

I have trouble closing zip tops and then have trouble getting them open because my hands are weak. As others have said, I too use clips to close store bought products that have zip top closures. I love WayToMisery suggestion of wooden clothes pins... very affordable.

I cut off the zip top part of prepackaged foods then roll the top down and secure with a rubber bad.

Plastic bag secured with a clothes pin or two.

Ok .. even myself have the patience to close those properly . So what do is I put the bag that I can’t or forget to close with the product in a ziploc bag and so even if it’s not close and spills out , it is in another bag .
hope it helps and works
