Why does milk from a glass bottle have cream at the top but milk from a plastic bottle doesn't?!
Milk used to be delivered unhomogenized in glass bottles. Then, it was made available homogenized in all kinds of containers--paper, plastic, and glass.
Answers: Whether or not cream floats on top of the milk is a function of whether it is homogenized or not. It has nothing to do with the type of container. If a little cream is floating on top of homogenized millk, it is easier to see it in a glass bottle, but the bottle does not affect the separation of the milk and cream.

Im not sure but is it because bottled milk comes fresh from the dairy.
that is probably because glass bottled milk is more fresh than the kind in the plastic
because glass bottles are less insulated, so it hardens at the top.
glass bottled is from the dairy and it's fresh
paper /plastic milk is processed differently and cream is removed at the bottling source.
The glass bottles are fresh full fat ( with cream ) milk as most plastic bottles contain UHT or pasteurised skimmed or half skimmed milk, I don't think fresh milk would keep long in plastic.
Milk in plastic bottles is homogenized, so doesn't separate.
Different kind of milk... There is skimmed or semi skimmed which have no cream then the full fat.Most of this is homogenised which means the cream will not separate from the milk... Only full cream non homogenised milk will separate to form a cream layer... Not sure the receptacle has any bearing on this.
milk from a bottle is less fresh because it sits in the shop waiting to be bought,but milk from a bottle is very fresh so it has a bit if a cream to it at the top
The milk that comes in bottles is fresh milk, the cream that you see on the top of the milk is used to make home made butter with but you will need alot of that cream to make butter with, cause you will see that cream form only one time in that bottle of milk.
