OK now let's find the guy that invented those crinkly Sun Chips bags.

agreed - and then lets ask them about the total fabrication that they are biodegradable.

Biodegradable... eventually.

edit: So I looked it up and it should only take 14 weeks in an active compost pile. I wonder if anyone has ever tested it?

Now I know who Kettle Chips hired to make their impossible to open bags.

I was just thinking about how Kettle Chips have a small but pronounced notch that you can grab and pull. I haven't had any angst opening a bag of chips in a long time.

And here i was, cursing the idiot at kettle who thought eating chips from the side of the bag was a good idea. Opening from the top allows for easy reach and easy reseal.

The guy we really need to find and punish is the one who invented "rigid plastic clamshells". The kind that "conveniently" transforms from product packaging into a razor-sharp weapon while you are trying to open it.

Clamshell packaging was made for retail shelves. To prevent shrinkage and increase product visibility, it was designed to be transparent while simultaneously difficult to open. The explosion of Amazon and other online retailers made the advantages of clamshell packaging moot. However if you are a manufacturer, it may not be economically feasible to produce two different types of packaging for different retailers so l…

Which is also a feature to discourage shoplifting.

Shrinkage is shoplifting.

Out of curiosity, what did you think 'shrinkage' meant in that context?

Shrinkage is shoplifting.

I believe shrinkage is most commonly used by retailers to mean theft by employees. Shoplifting is customer theft.

Shrinkage encompasses all of the above [1]. The retailer I worked at for a few years (::shudder::) used this definition.

I love learning about things I would never come across in everyday life, like how a packing machine works and the problems no one would ever think to think of like air pressure and altitudes. Then also the restrictions put in place and how to come up with a creative solution to a problem. This is the kind of stuff I live for.

The air pressure certainly has an effect. I live in an only somewhat-high-altitude city (Calgary) and most of the chip bags you see are puffed up like balloons.

At 4:10 in this video https://www.youtube.com/watch?v=LkqBbr7Ewsw you can see a VFFS machine in action. (I find 'how its made' to be musak for nerds but that is a different post :-)

You can link directly to 4:10 in the video.

"The point here is that while technical options exist to prevent premature opening of the bag, such as reducing the initial air pressure in the bag, attempting to add this to the existing processing equipment would be a nightmare. So it was necessary to increase the seal strength." You could also reduce the air pressure in the factory , e.g. by building it in one of the aforementioned high-altitude regions.

And/or heat up the air filling the bag. As air cools, the volume decreases.

The right solution would be to squeeze to depress the bag a bit as it's sealed. Increasing the seal strength is a quick and dirty hack, but as we've all learned too well from software, the right solutions often got trumped by quick and dirty hacks. The customers just have to live with the consequence.
