why don't all potato chip bags have a ziplock seal?

I don't see how the nitrogen flushing or the zipper permeability are issues. The bag is still heat sealed at the top like they always are. Reference the archer farms bag.

Archer Farms chips are also pretty high quality.

The zippers create nitrogen flushing issues when passing through the formers. Additionally, although they are nitrogen flushed residual O2 levels are higher in zipper bags than traditional sealed bags and zipper bags lose the nitrogen quicker.

:hmm:

so you already know of an example where this already exists?

well....do you also agree that pirate's booty chips kinda suck?

I don't think Archers Farms is that great, either, for the price. Give me regular old Lays any day of the week.

Middleswarth is the only brand I know that does this, but only on 1 size bag. I don't think you can get this brand outside of PA though.
 
The "cost" would be the cost of buying a new sealing machine, incorporating it into the factory process, and the salary $ spent on doing the first two. For incumbent firms, i'd imagine that this is a signicant sum.

this. when i was in college i took a marketing class one summer and we had a project for which i had to interview a guy at granny goose and this is what he told me. maybe he was lying though, maybe they just leave it off so your chips will go stale and you will have to buy a new bag

A penny or two doubles the price of the bag. It also creates an easy way for the consumer to seal the bag and therefore will lead some people to eat less. Both of those things are bad for the manufacturer, so why would they do it?

In addition to the costs of the bag itself, adding a ziploc type seal would create manufacturing issues. Chip bags come in giant continuous rolls that are fed into the packaging machine. Adding a ziploc would increase the costs since another step or two, and the required additional machinery, is needed.

Not worth it when a bag of chips is often just dumped into a bowl.

In short, buy a couple chip clips. 😎
 
if anything, i would want tortilla chips that had a seal. i always run out of salsa like halfway through the bag.

why do the generic bags of cereal have ziploc seals... iirc they have thad them for quite a long time.

See, free market works. The people get what they want and the companies will do what is in the best interest of their customers.

Gawd yes...gotta save that penny or two per bag...

Because all of these companies already have the machinery and hardware on site to create a ziplock seal on chip and cereal bags? There isn't some magical switch that enables their line to make a ziplock section of the bag... so I don't know why you think it'd cost so little.
