A recent study showed pizza boxes increased the risk of miscarriage x16. The grease proofing is not wax (ok I show my age or ignorance) but a flourine polymer or a version of teflon. It is also found in food wraps (eg burger wrappers) sports clothes and furniture. It may resist water but absorbs into skin. Another killer from Dupont. It is an endocrine disrupter and has an input in obesity and diabetes etc.
This adds to the chemical load in the home and contributes to our declining health.
This got me to thinking about food wrap and oven proof papers etc. I found how to make home made food wrap and dish covers. They are reusable and work out cheaper than buying plastic wrap.
Easy to make.
