Can PE plastic wrap be used in food storage containers?

As a supplier of PE plastic wrap, I often get asked this question. PE, or polyethylene, is one of the most common plastics used in food packaging due to its versatility, safety, and cost - effectiveness. In this blog, I'll delve into the details of whether PE plastic wrap can be used in food storage containers and explore its various aspects.

The Safety of PE Plastic Wrap for Food Contact

PE plastic wrap is generally considered safe for food contact. Polyethylene is a polymer made from ethylene monomers. It has a simple chemical structure, which means it is less likely to react with food and leach harmful substances. The U.S. Food and Drug Administration (FDA) and other international food safety authorities have approved the use of PE plastic wrap for direct food contact.

When it comes to food storage, the main concern is the potential for chemicals to migrate from the plastic wrap into the food. With PE plastic wrap, the risk is extremely low. Unlike some other plastics, PE does not contain phthalates, bisphenol A (BPA), or other potentially harmful chemicals that have been linked to health issues. This makes it a popular choice for wrapping everything from sandwiches to leftovers.

Benefits of Using PE Plastic Wrap in Food Storage Containers

1. Barrier Properties
   PE plastic wrap provides an effective barrier against oxygen, moisture, and contaminants. Oxygen can cause food to spoil by promoting the growth of aerobic bacteria and oxidation of fats, which leads to rancidity. By creating a tight seal around the food in the storage container, PE plastic wrap helps to keep oxygen out, extending the shelf - life of the food.

Moisture is another factor that can affect the quality of stored food. If food dries out, it can become tough and lose its flavor. On the other hand, excess moisture can lead to mold growth. PE plastic wrap helps to maintain the right level of moisture in the food, keeping it fresh and flavorful.

2. Flexibility and Cling
   One of the key advantages of PE plastic wrap is its flexibility and cling. It can easily conform to the shape of the food and the storage container, creating a tight and secure seal. This is particularly useful for irregularly shaped items or containers with non - standard sizes. The cling property also means that the plastic wrap stays in place without the need for additional adhesives or fasteners, which could potentially contaminate the food.

3. Cost - Effective
   PE plastic wrap is relatively inexpensive compared to other types of food packaging materials. This makes it an economical choice for both home and commercial use. Whether you're a household looking to store leftovers or a restaurant packaging take - out meals, PE plastic wrap offers a cost - effective solution for food storage.

Types of PE Plastic Wrap for Food Storage

1. PE Film Wraps
   PE Film Wraps are a common type of PE plastic wrap. They are available in different thicknesses and widths, allowing you to choose the most suitable option for your specific food storage needs. Thicker film wraps are more durable and better suited for heavy - duty applications, such as wrapping large cuts of meat or bulky items. Thinner film wraps, on the other hand, are more flexible and ideal for wrapping smaller items like individual sandwiches.

2. Polyethylene Cling Film
   Polyethylene Cling Film is designed to have excellent cling properties. It adheres tightly to itself and to the surface of the food and the storage container, creating a secure seal. This type of plastic wrap is often used in households and in the food service industry for wrapping fresh produce, deli meats, and cheeses.

   

3. PE Micro - Perforated Film
   PE Micro - Perforated Film is a specialized type of PE plastic wrap. It has tiny holes or perforations that allow for a controlled exchange of air and moisture. This is particularly beneficial for storing fresh produce, as it helps to prevent the build - up of condensation, which can lead to mold growth. The micro - perforations also allow the produce to "breathe," maintaining its freshness and quality.

Considerations When Using PE Plastic Wrap in Food Storage Containers

1. Temperature
   While PE plastic wrap is generally safe for food contact, it has limitations when it comes to temperature. It is not recommended to use PE plastic wrap in the oven, microwave (unless specifically labeled as microwave - safe), or in contact with hot liquids or foods that are above its melting point. High temperatures can cause the plastic wrap to melt, releasing potentially harmful substances into the food.

2. Proper Usage
   To ensure the safety and effectiveness of PE plastic wrap, it's important to use it correctly. Make sure to cover the food completely and create a tight seal. Avoid using torn or damaged plastic wrap, as this can compromise the barrier properties and allow contaminants to enter.

Conclusion

In conclusion, PE plastic wrap can be safely and effectively used in food storage containers. Its safety, barrier properties, flexibility, and cost - effectiveness make it a popular choice for food storage. There are different types of PE plastic wrap available, each with its own unique features and benefits, allowing you to choose the most suitable option for your specific needs.
