Thanks for the feed back.
bbracken677, I came across that discussion a while back and was intrigued by it and as noted there were differing opinions. Most of our water supply and drain lines are PVC these days.http://topics.wisegeek.org/topics.htm?pvc-sewer-pipe
and is used widely in the food industry today.
"Vinyl (polyvinyl chloride, or PVC) provides excellent clarity, puncture resistance and cling. As a film, vinyl can breathe just the right amount, making it ideal for packaging fresh meats that require oxygen to ensure a bright red surface while maintaining an acceptable shelf life.
Examples: Plastic food wrap, shrink wrap, garden hoses, shoe soles"http://virtualweberbullet.com/plastics.html
Polyvinyl chloride (PVC) is used in all manner of food wraps. It is transparent and strong and clings very well to food when used as a wrap, but it also allows enough oxygen through its surface for products that need to "breathe," such as fresh meats. Garden hoses and shoe soles are also often made with PVC, as are the white plastic pipes used for household plumbing.
How Do I Tell If it Is Food Grade Plastic?
Only seven types of plastic are considered "food grade" by the U.S. Food & Drug Administration. Plastics used to package food must be of high quality and cannot contain harmful dyes or chemicals. The Society of Plastics Industry has established a seven-point system of categorizing and labeling food-grade plastics.http://www.ehow.com/way_5819448_do-tell-food-grade-plastic_.html
Tomer1, I agree and do plan on ordering proper hoops for pressed cheeses but this is for Stilton (not pressed) and I have it. so baring any safety concerns it would be interesting to try.
