I remember we use to have tubes that bent up well but were very soft a tin like material that eventually they found because it had lead in them it leached into the toothpaste such that now we have plastic toothpaste tubes predominatly made in the US.
That sounds about right. I do remember those tubes that rolled up easily and were made of a bendable metal. In those days, I was pretty bad about brushing my teeth so it's probable that I wasn't affected that much by whatever lead content there was. I did get a lot of cavities, though.
Hello, Actually it was before that when dentistry figured out that the lead could leech into the toothpaste. What really changed the dispenser packaging of toothpaste was WW11, around the late 1940's...The war created a shortage of lead and the explosion of plastics uses suddenly caused toothpastes dispensers to change over to plastic and it's been that way since.
