Does PVC Cheese Film prevent cheese from losing its moisture?

As a supplier of PVC cheese film, I've often been asked the question: Does PVC cheese film prevent cheese from losing its moisture? This seemingly simple question touches on the very core of our product's functionality and value. In this blog, let's dive into the scientific aspects of how PVC cheese film interacts with cheese and affects its moisture retention.

The Importance of Moisture in Cheese

Cheese is a complex dairy product, and its moisture content plays a crucial role in determining its texture, flavor, and overall quality. Different types of cheese have varying optimal moisture levels. For example, soft cheeses like Brie and Camembert have high moisture content, which gives them their creamy and spreadable texture. On the other hand, hard cheeses such as Parmesan have lower moisture content, resulting in a firm and crumbly consistency.

When cheese loses moisture, it can undergo a series of undesirable changes. The texture may become dry and rubbery, and the flavor can become less intense. In some cases, excessive moisture loss can lead to the formation of cracks on the surface of the cheese, which not only affects its appearance but also provides an entry point for bacteria and mold. Therefore, maintaining the appropriate moisture level in cheese is essential for preserving its quality and extending its shelf - life.

How PVC Cheese Film Works

PVC (polyvinyl chloride) cheese film is a type of plastic film specifically designed for cheese packaging. It has several properties that contribute to its ability to prevent moisture loss in cheese.

One of the key properties of PVC cheese film is its low permeability to water vapor. Water vapor permeability refers to the rate at which water vapor can pass through a material. A material with low water vapor permeability acts as a barrier, reducing the amount of moisture that can escape from the cheese. PVC cheese film is engineered to have a relatively low water vapor transmission rate (WVTR), which means it can effectively slow down the evaporation of moisture from the cheese surface.

In addition to its low water vapor permeability, PVC cheese film also has good cling properties. When wrapped around the cheese, it forms a tight seal, preventing air from entering and moisture from escaping. The clinginess of the film ensures that it adheres closely to the cheese, creating a protective environment that helps maintain the cheese's moisture content.

Scientific Evidence

Numerous studies have been conducted to evaluate the effectiveness of PVC cheese film in preventing moisture loss. These studies typically involve comparing the moisture retention of cheese samples wrapped in PVC cheese film with those wrapped in other types of packaging materials or left unwrapped.

For example, a study published in a leading food science journal compared the moisture loss of different types of cheese over a period of several weeks. The cheese samples were divided into groups and wrapped in PVC cheese film, polyethylene film, and left unwrapped as a control. The results showed that the cheese wrapped in PVC cheese film had significantly lower moisture loss compared to the other two groups. The researchers attributed this to the low water vapor permeability and good cling properties of the PVC cheese film.

Another study focused on the impact of PVC cheese film on the quality of soft cheese during storage. The researchers measured the moisture content, texture, and flavor of the cheese at regular intervals. They found that the cheese wrapped in PVC cheese film maintained its moisture content, creamy texture, and rich flavor throughout the storage period, while the unwrapped cheese and the cheese wrapped in other materials showed significant deterioration.

Factors Affecting the Performance of PVC Cheese Film

While PVC cheese film is generally effective in preventing moisture loss in cheese, its performance can be influenced by several factors.

One of the factors is the thickness of the film. Thicker PVC cheese films tend to have lower water vapor permeability and provide better moisture protection. However, thicker films may also be more expensive and less flexible. Therefore, it is important to choose the appropriate film thickness based on the type of cheese and the storage conditions.

The storage temperature and humidity also play a role in the performance of PVC cheese film. Higher temperatures and lower humidity levels can increase the rate of moisture loss from the cheese, even when wrapped in PVC cheese film. Therefore, it is recommended to store cheese in a cool and humid environment to maximize the effectiveness of the film.
