How to store PE cling film to keep it sticky?

As a supplier of PE cling film, I understand the importance of maintaining the stickiness of this essential product. PE cling film, known for its versatility and convenience, is widely used in households, restaurants, and food industries for wrapping food items, preserving freshness, and preventing spills. However, improper storage can lead to a loss of stickiness, making the film less effective and frustrating to use. In this blog post, I will share some scientific and practical tips on how to store PE cling film to keep it sticky.

Understanding the Science Behind Stickiness

Before delving into storage techniques, it's crucial to understand what makes PE cling film sticky. The stickiness of PE cling film is primarily due to the electrostatic charges generated when the film is unrolled. These charges create an attractive force between the film and the surface it comes into contact with, allowing it to adhere firmly. Factors such as humidity, temperature, and contamination can affect these electrostatic charges, leading to a reduction in stickiness.

Ideal Storage Conditions

Temperature

The ideal temperature for storing PE cling film is between 50°F (10°C) and 70°F (21°C). Extreme temperatures can damage the film's structure and reduce its stickiness. For example, high temperatures can cause the film to become soft and lose its shape, while low temperatures can make it brittle and less flexible. Avoid storing the film in areas that are exposed to direct sunlight or near heat sources such as stoves, ovens, or radiators.

Humidity

Humidity levels also play a significant role in maintaining the stickiness of PE cling film. Excessive humidity can cause the film to absorb moisture, which can interfere with the electrostatic charges and reduce its stickiness. On the other hand, very low humidity can make the film dry and brittle. The ideal humidity level for storing PE cling film is around 40% to 60%. If you live in an area with high humidity, consider using a dehumidifier in the storage area.

Contamination

Contamination can also affect the stickiness of PE cling film. Dust, dirt, and oil can accumulate on the film's surface, preventing it from adhering properly. To prevent contamination, store the film in a clean and dry environment. Avoid touching the film with dirty hands or allowing it to come into contact with greasy or sticky surfaces.

Storage Methods

Original Packaging

One of the simplest and most effective ways to store PE cling film is to keep it in its original packaging. The packaging is designed to protect the film from light, moisture, and contamination. Make sure to seal the packaging tightly after each use to prevent air and moisture from getting in. If the original packaging is damaged or lost, you can transfer the film to a resealable plastic bag or an airtight container.

Flat Storage

Storing the PE cling film flat is another good option. This helps to prevent the film from wrinkling or curling, which can reduce its stickiness. You can store the film on a shelf or in a drawer, making sure it is not compressed by other items. If you have multiple rolls of film, stack them neatly to avoid any unnecessary pressure on the rolls.

Vertical Storage

Some people prefer to store their PE cling film vertically. This can be a space-saving option, especially if you have limited storage space. However, it's important to ensure that the film is stored in a way that prevents it from unwinding or becoming damaged. You can use a dispenser or a holder specifically designed for cling film to keep it in place.

Tips for Using and Storing PE Cling Film

Proper Handling

When using PE cling film, make sure to handle it properly to avoid damaging the film or reducing its stickiness. Always unroll the film slowly and gently, and avoid stretching it too much. When wrapping food items, use a clean and dry surface to ensure a good seal.

Regular Inspections

Regularly inspect your PE cling film for any signs of damage or degradation. If you notice any tears, holes, or a loss of stickiness, it's time to replace the film. Using damaged or degraded film can not only affect the quality of your food but also pose a health risk.

Choose the Right Type of PE Cling Film

There are different types of PE cling film available on the market, each with its own unique properties and uses. For example, PE Meat Film is specifically designed for wrapping meat, while PE Film Wraps are more versatile and can be used for wrapping a variety of food items. PE Biodegradable Film is an eco-friendly option that is made from biodegradable materials. Choose the right type of film for your specific needs to ensure the best results.
