Saran (plastic)

Saran (Plastic)

Saran is a popular brand of plastic wrap, often used in food storage and preparation. It is a type of polyvinylidene chloride (PVDC) plastic, which is a synthetic polymer that is produced by the polymerization of vinylidene chloride.

History

Saran was first developed in the mid-20th century by the Dow Chemical Company. It was initially used for industrial applications, but its use quickly expanded to household products when the benefits of its properties were recognized.

Properties

Saran plastic has several properties that make it ideal for food storage. It is resistant to water, grease, and chemicals, making it an effective barrier against contamination. It also has excellent cling properties, allowing it to adhere well to various surfaces.

Uses

The primary use of Saran plastic is in the form of Saran Wrap, a thin, clear film that is used to cover food items to keep them fresh. It is also used in a variety of other applications, including packaging for various consumer goods.

Environmental Impact

Like all plastics, Saran has an environmental impact. It is not biodegradable and can take hundreds of years to break down in the environment. This has led to concerns about its impact on wildlife and ecosystems, and efforts to reduce its use or find more sustainable alternatives.

Alternatives

There are several alternatives to Saran plastic, including other types of plastic wrap, aluminum foil, and reusable containers. Many of these alternatives have their own advantages and disadvantages, and the choice between them often depends on the specific needs of the user.
