To answer your question, let’s delve into the properties of Saran Wrap and why it may not be suitable for use in the oven. Saran Wrap is a type of cling film commonly used for food storage and preservation. It is made from a thin plastic material called polyvinylidene chloride (PVDC), which is known for its excellent cling and barrier properties.
However, when it comes to heat resistance, Saran Wrap falls short. The melting point of most cling films, including Saran Wrap, is typically around 220F-250F (104C-121C). This means that when exposed to temperatures higher than this, the plastic begins to soften and eventually melt.
In comparison, aluminum foil, which is often used in conjunction with plastic wrap in the oven, has a much higher melting point of around 1220F (660C). This makes it a suitable choice for protecting food from direct heat and preventing plastic wrap from melting.
When plastic wrap melts in the oven, it can not only ruin the food but also release potentially harmful chemicals into the air. These chemicals can be harmful if inhaled or come into contact with food. Therefore, it is essential to avoid using plastic wrap alone in the oven without the protection of aluminum foil or other heat-resistant materials.
Personal experience-wise, I once made the mistake of using plastic wrap to cover a casserole in the oven. To my dismay, the plastic wrap melted and created a mess, not to mention the unpleasant smell it produced. Since then, I have made sure to always use aluminum foil or oven-safe lids instead.
Saran Wrap and other cling films are not suitable for use in the oven as they have a low heat resistance and will likely melt at temperatures above 220F-250F. To protect your food and avoid potential health risks, it is best to use aluminum foil or other oven-safe materials when cooking or baking in the oven.
