I’m willing to accept that some of it is aesthetics; but mostly it’s theft prevention. Some people are willing to steal anything they can easily get away with. Jerks.
We have two of these. They are pretty decent indeed.
A simple box cutter from your local hardware store works great. Get one with an adjustable blade. It’s the only thing I use, and the blade lasts forever.
My fantasy film scene:
A man who turns out to be a packaging engineer is kidnapped.
He wakes up in a locked room.
The only thing in it is a pile of non-openable packages he has designed.
There are no tools.
He’s told he will not be released until he opens every package.
I envision him finally released with hands cut and bloody.
What it says: Easy open resealable package
What it means: Cut open with scissors and put any leftover product in your own ziploc bag.
Actually now that I come to think of it, a lot of packaged food products now have the little scissors near one end of a long dashed line. Ten and more years ago, I don’t remember scissors being so necessary in the kitchen, but now I couldn’t get along without them.
My grandmother had kitchen shears, but she didn’t use them to open packages, she used them to snip parsley and cut the wings off chicken and things like that. Nowadays, I’m tempted to get several pairs of utility scissors and keep them in just about every room in the house, because it seems that more and more things can’t be opened without sharp implements.
You know I have one simple request and that is to have sharks with some freakin laser beams attached to their heads.
I alway have one of these on me. Like cutting through butter.
All these years of Ziplock baggies and no one has put one on the BACON PACKAGE. :rolleyes:
I even gotta cut the package a few times before I hit the air pocket where the bacon resides, and not just more sealed plastic. :mad:
Just as well though, as I’m used to cooking all of it at once in the oven and freeze, now anyway. 
Why the hell won’t they package bacon in recloseable packages anyway?
Smoked salmon too.
I too used to struggle with those plastic clamshells but now I that I’m older and have a pair of heavy duty scissors and a utility knife within reach all the time, I just slice open three sides and pop the sucker out. No muss, no fuss. Zipties are even easier. They just need a scoring and then they snap in half.
In my experience, even this is barely able to open a lot of that packaging.
And I have a large collection of knives, tools, and other weapons.
