Almost everything I drink out of is lined with plastic. Milk or juice containers, water bottles, and most reusable on the go cups are made of plastics or have a plastic liner.

food packaging plastics are short lived (time from packaging to consumption is <2 years) and they are not exposed to sun nor heat. They are safe.
But long-term plastics in tubing are exposed continuously to heat (hot water) and will start falling apart and leech chemicals, because they are exposed over long-term
>After the tenth pin hole leak and lots of shark bite fixes, I am not fond of copper.
It's my understanding that the vast majority of pinhole copper leaks are caused by poor solder jobs. Solder gets inside the pipe and causes a vortex that can eat through the copper.
The solution to this is to use solderless copper ProPress fittings for everything. Not only is this much more clean and faster to install, but the inside of the pipe is flush/smooth with the fitting.
