The dairy industry is desperately trying to break away from everybody having identical containers and competing on price.[1] Milk in sippable pouches may become a thing. With bigger markups!
I'm afraid of all these "innovations" they described there. Nice ways to decommoditify and justify price increases, in direct opposition of my goals as a consumer: to reduce food and packaging waste.
I'll grant them that kids do love things they can squeeze. My 18mo loves the baby food pouches. When we're in the store, she'll spot them and grab them off the shelves as we're wheeling by them. We ended up buying resealable pouches that we stuff with home-made food, to cut down on plastic waste.
