ziploc mylar bags

hi new to the forum.got a question about mylar bags.how about using the ones with the ziploc on them to reseal them.i was planning on using the one gallon ones in five gallon buckets with oxygen absorbers thanks for your ansewers

https://www.usaemergencysupply.com/emergency_supplies/mylar_food_storage_bags.htm I'd rather use them even though they cost twice as much. I think it would be really convenient to be able to zip them back up so easily after opening. Will they seal just as well as heat sealing? Thanks.

I noticed while looking at a particular website for mylar bags they also sold ziploc mylar bags. My question is do you think ziploc is just as good as the ones you have to seal with heat or what? What are your thoughts on this?
