<p>[QUOTE=&quot;tommyc03, post: 2649436, member: 17665&quot;]Okay, I need a science lesson, really, not being snarky at all. I thought that most plastics containers were pliable because they use softening agents/chemicals to keep them that way. Those chemicals do not leach over extended periods of time? I know I have seen some terrible looking coins coming out of those Canadian albums. Different chemical make up? At work, where we used many different types of plastics, I was not allowed to know the chemicals used due to the proprietary information involved. But we used Polypro, polyethylene , polystyrene and others but they all came in pelletized form before hitting the injection molding machines.[/QUOTE]</p><p><br /></p>
