What Is the Difference Between Cling Wrap and Plastic Wrap?

Beyond the Surface

While often used interchangeably, cling wrap and plastic wrap are distinct products with unique characteristics. Both serve the purpose of food preservation, but their composition, properties, and applications differ.

Composition Matters

Cling wrap, renowned for its clinginess, is typically made from polyvinylidene chloride (PVDC) or polyvinyl chloride (PVC). These materials provide the adhesive properties that allow the wrap to adhere firmly to surfaces. In contrast, plastic wrap is generally made from low-density polyethylene (LDPE), a more flexible and less clingy material.

Clinginess: A Key Differentiator

Cling wrap's defining characteristic is its ability to adhere to surfaces without additional pressure. This clinginess is crucial for creating an airtight seal, preventing food from drying out or becoming contaminated. Plastic wrap, while also capable of adhering, often requires more effort to secure a tight seal.

Stretchability and Flexibility

Both cling wrap and plastic wrap offer a degree of stretchability, allowing them to conform to various food shapes. However, cling wrap tends to be more stretchable and flexible, making it easier to wrap around irregular-shaped items. Plastic wrap may require more effort to stretch and can be less forgiving with complex shapes.

Permeability and Food Preservation

Cling wrap excels at creating a barrier against moisture, air, and odors. Its clingy nature minimizes the passage of gases and moisture, preserving food for longer. Plastic wrap, while providing some protection, may have slightly higher permeability, allowing for more moisture and air exchange.

Heat Resistance

Cling wrap is often designed to be heat resistant, making it suitable for use in microwave ovens. Plastic wrap, however, may not withstand high temperatures and may melt or deform.

Availability and Branding

Both cling wrap and plastic wrap are widely available from various manufacturers and brands. Cling wrap is often associated with specific brands that have established a reputation for their clingy and stretchy properties. Plastic wrap may be found in generic or store brands, offering a wider range of options.

Choosing the Right Wrap

The choice between cling wrap and plastic wrap depends on your specific needs and preferences. If you require a highly clingy and airtight seal, cling wrap is the ideal option. For general-purpose wrapping or applications that don't require extreme clinginess, plastic wrap may be sufficient.

In conclusion, while cling wrap and plastic wrap share the same basic function, their distinct properties make them suitable for different applications. By understanding the key differences between these two types of wrap, you can make an informed choice and ensure that your food is properly preserved.
