Glad wrap

Plastic Wrap Plastic wrap is a thin plastic film typically

used for sealing food items in containers to keep them fresh. Plastic wrap, typically sold on rolls in boxes with a cutting edge, clings to many smooth surfaces and can thus remain tight over the opening of a container without adhesive or other devices. Common plastic wrap is roughly 0.01 mm thick.

History

Plastic wrap's history is built on a lab error and serendipity. Plastic wrap was invented in 1953 by a scientist who was trying to make a hard plastic cover for his car; his experiment was completely unsuccessful but he then found the usefulness of plastic wrap which he happened to create instead.

Materials

Plastic wrap was first made from PVC, which remains the most common material, but non-PVC alternatives are now being sold because of concerns about the risk in transfer of plasticizers from PVC into food.

Conclusion

We have found from this PowerPoint that glad wrap is very bad for the environment and we should try reusing glad wrap.
