New research aims to cut down on waste -- and consumer frustration -- with a novel approach to creating super slippery industrial packaging. The study establishes a method for wicking chemically compatible vegetable oils into the surfaces of common extruded plastics, like those used for ketchup packets and other condiments.

These ketchup bottles are the superior ones: http://moziru.com/images/ketchup-clipart-heinz-4.jpg [moziru.com]
Add an inner layer of omniphobic coating, like we've been waiting on for years now, and the ketchup problem will be solved forever.

Oh I agree those bottles are great! The lid/valve system is really good too and they sit upside down so product is always ready to dispense. It is a highly refined design.
I've seen the same valving system on mustard and I just got one with mayo too. Nice sharp stream sprays out when you squeeze and there is no mess.
It is great!
I don't like ultra slow pouring glass ketchup bottles its just that they aren't unworkably hard to drain.

If by superior, you mean only has 3/4 of the contents that an upright bottle has. Those upside down bottles are smaller than the regular ones.

Volume doesn't matter. Only $/volume matters. And I've seen non-Heinz brands use the same bottle design.

It doesn't make a significant difference in the cost effectiveness but different volumes can lead to significant changes in the amount of waste generated for delivering the same product.
A good example is a normal consumer box of corn flakes from a supermarket vs the same volume of corn flakes in single serving boxes like from grade school or a hotel. The weight of the many single serving boxes greatly exceeds the larger box. The smaller internal volume leads to more waste and that isn't really a good thing.
I don't know about conversion from glass to plastic but when staying in the same packaging technology that always holds true.

The upside down bottles hold 750 ml while the regular bottles hold a litre. Same price here. YMMV.

If they are like the bottles I use, they have a flaw. The labels says that once open, they should be stored in a cool place, which for most people is the refrigerator. When you take them out and put them on the table at ambient room temperature, the air in the top of the upside down bottle increases in pressure, so when you open them, a steady stream of ketchup is emitted before you even squeeze the bottle. This is suboptimal, and often messy.
