When Was Plastic Wrap Invented? A History of Its Invention and Impact on Our Lives

Introduction

Plastic wrap is a staple in many kitchens around the world. It’s an essential part of food storage, helping to keep food fresh and prevent spoilage. But when was plastic wrap invented? In this article, we’ll explore the history of plastic wrap, from when it was first invented to its impact on our lives today.

A History of Plastic Wrap: When It Was First Invented

The first plastic wrap was invented in 1933 by Ralph Wiley, a scientist working for Dow Chemical Company. The original formula was made of polyvinylidene chloride (PVDC), a type of plastic that was highly resistant to moisture. This made it ideal for sealing food and preventing spoilage. The product was initially marketed as “Saran Wrap” and was sold in rolls with perforated edges for easy use.

In the 1950s, Dow introduced a new version of plastic wrap made from polyethylene. This version had a lower melting point than the PVDC version, making it easier to use. Polyethylene is also cheaper to produce and more widely available, so it quickly became the most popular type of plastic wrap.

Since then, plastic wrap has gone through several iterations, with different types of plastics being used depending on the desired properties. For example, some types of plastic wrap are designed to be heat sealable, while others are designed to be microwavable. The current market is dominated by polyvinyl chloride (PVC) and polyethylene (PE) wraps.

Despite the invention of plastic wrap almost 90 years ago, the mystery of who actually invented it remains. Many people have been credited with the invention, including William Chase of the Reynolds Metals Company and Earl Dickson of Johnson & Johnson. However, there is no definitive answer as to who actually invented it.

How Plastic Wrap Changed the Way We Store Food

Since its inception, plastic wrap has changed the way we store food. It has become an essential part of food preservation, preventing spoilage and keeping food fresh for longer. According to a study conducted by the American Institute of Baking, plastic wrap is one of the most effective ways to preserve food, as it blocks out oxygen, which can cause food to spoil faster.

Plastic wrap has also made food storage much easier. It’s easy to use, can be found in nearly any grocery store, and is relatively inexpensive. This makes it an attractive option for both home cooks and professional chefs alike. It’s also great for packing lunches, as it keeps food fresher for longer and helps to prevent messes.

In addition, plastic wrap is also often used in the medical industry. It’s used to cover wounds, protect bandages, and even cover prosthetics. It’s also used to protect sterile equipment, such as surgical tools, from contamination.

Conclusion

Plastic wrap has come a long way since its invention almost 90 years ago. It has revolutionized the way we store food, making it easier and more effective. From preventing spoilage to packing lunches, plastic wrap has become an essential part of our lives. Although the mystery of who invented plastic wrap remains, its impact on our lives is undeniable.
