In observance to Nat'l Toothpaste Tube Day, do you know why they started using plastic vs. metal tubes?

The really old ones had lead in them.

Aluminium is also not good over time.

So can I play the Tuber again :)

Tube a toothpaste!

Interesting question to which I can't seem to find a definitive answer here on the net. I do hope that you pick a BA and then let the rest of know why toothpaste companies made the switch. I'm assuming it was a cost saving measure.

So what musical instrument are you going to buy? <g>

EDIT: I REMEMBER when toothpaste came in metal tubes and they never got holes in them just weird creases that made it diffcult at times to squeeze out all the toothpaste.

Everything's plastic these days, plus the metal tubes would get holes in them.

The aluminum content in the metal tubes is not good for tooth enamel.

So that terrorists could pass their plastic explosives through metal detectors at the airport.

How are you supposed to squeeze the toothpase out in metal tubes?

I'm not buying an instrument, I'm broke. Thanks anyways.

I was getting metal splinters when brushing before.

cheaper and easier to use. i have enough instruments, i already spent 2 hrs playing violin 2day

Mostly, I'm sure, because it was cheaper, but plastic was also easier to use.

Tubes were harder to roll up?
