Hi every body, i recently had a discussion with someone who tried to tell me that there is a plastic which is breatheable.He claims that it is safe to keep it in direct contact with maple foliage thru freezes and on a sunny day in the 60's. So my question is , does it exist? i have never had good experiences with direct plastic to foliage contact on a warm sunny day. I figure if it exists someone here could tell me where to find it. Thanx
