This is the right way to use food wrapping film, ensuring safety.

Proper usage of food wrap is crucial in ensuring that food is well-preserved and safe for consumption. It plays a vital role in maintaining the freshness and quality of the food while keeping it protected from external factors. By correctly utilizing food wrap, we can confidently ensure the well-being of consumers and provide them with peace of mind when it comes to the safety and quality of their food.


Nowadays, food packaging film is an essential item in many households’ kitchens. It not only helps to preserve food better, but also saves time and effort for homemakers. However, not everyone knows how to use food packaging film correctly to ensure effectiveness and safety.

Correct use of food packaging film

To ensure the most effective food storage, you can use food packaging film in the following ways.

Choose the right food packaging film

The first important note when buying food packaging film is not to be tempted to buy cheap, low-quality products. The material used must be safe as it will come into direct contact with food, have good heat resistance, and be water resistant. The film should be flexible and have good adhesion to facilitate food packaging.

Poor quality products may be made from unsafe plastic, which can be toxic. Inferior packaging film can also allow air and moisture to penetrate through the cracks, creating conditions for bacteria to develop, posing a health risk for consumers.

In addition, you need to consider the purpose of use to choose the right type of film. For example, PVC film is suitable for dry food, while PE film is suitable for wet food. Using unsuitable film can cause food to spoil or lose its flavor.

Ensure dry and clean film

Before using, you need to ensure that the food packaging film is clean and dry. Food packaging film is usually stored in rolls and can be dusty, greasy, or moist. Unclean film can contaminate food and pose a health risk.

Handle correctly

When cutting the film, avoid tearing it; cut the film into pieces that fit the size of the food to be preserved to avoid waste and ensure safety.

Make sure you tightly seal the food to prevent air from entering. Use your fingers to press the edges of the film tightly to ensure a tight seal with no gaps, helping to preserve food as best as possible. Improper packaging can cause food to become contaminated or lose its flavor.

Note when using a microwave

If you plan to use film in the microwave, make sure the film you choose is safe for this purpose. Follow the manufacturer’s instructions on how to use film in the microwave to avoid the risk of fire and explosion.

Check the expiration date

Always check the expiration date of the food packaging film; do not use expired film to ensure food hygiene and safety.

Store at the appropriate temperature

Foods packaged with film should be stored at the appropriate temperature. For example, frozen foods should be stored at -18 degrees Celsius or lower. For fresh foods, you should also store them at a lower temperature to increase the preservation time.

Some uses of food packaging film

By creating a sealed environment with little air, food packaging film helps extend the shelf life of food, reduce food waste, and save costs. In addition to the function of food preservation, food packaging film also has the following uses:

Moisture retention: Some types of food packaging film have the ability to retain moisture, preventing dry food from becoming dry and helping to maintain its softness and freshness.

Chemical pollution prevention: Food packaging film can prevent food from coming into contact with chemicals from the external environment, helping to protect consumers’ health.

Protection against mechanical impact: Food packaging film can protect food from mechanical impacts such as impact, scratches, or breakage during transportation and storage.

Convenience in packaging: Food packaging film is easy to use and can be customized in size to fit different types of food, making it convenient for packaging and preservation.
