But not PVC (polyvinyl chloride). -----Original Message----- From: Timothy McShane [mailto:[log in to unmask]] Sent: Thursday, August 28, 2003 8:17 AM To: [log in to unmask] Subject: Re: polyethylene vs. polypropeline(sp?) sleeves/bags [faked-from] I'm not a conservator, but it has been my understanding that as a general guideline, "poly" plastics are safe. This includes both polyethylene and polypropylene, as well as polystyrene and polyester.
