Hey everyone! As a supplier of Functional Film, I've been getting a lot of questions lately about the gas - barrier function of our products. So, I thought I'd take the time to break it down for you in this blog post.
Let's start with the basics. What exactly is the gas - barrier function? Well, in simple terms, it's the ability of a film to prevent the passage of gases through it. This is super important in a whole bunch of industries, from food packaging to electronics.
In the food industry, for example, keeping oxygen out is crucial. Oxygen can cause food to spoil, lose its flavor, and even develop harmful bacteria. That's where our Functional Film comes in. Our films are designed to have excellent gas - barrier properties, which means they can keep oxygen away from the food inside the package. This extends the shelf - life of the food, reduces waste, and keeps the taste and quality intact.
Take our Anti Ageing Film for instance. It's not just about food, though. This film can also be used in other applications where preventing gas exchange is essential. It has a special composition that blocks oxygen and other gases very effectively. The technology behind it is pretty cool. We've developed a unique polymer blend that creates a tight molecular structure. This structure acts like a wall, stopping gas molecules from passing through.
Another area where the gas - barrier function is vital is in the medical field. Mucous Membrane protection is a big deal. Our Functional Film can be used to create protective barriers that prevent the entry of harmful gases and microorganisms. For example, in wound dressings, the film can keep out oxygen and bacteria, which helps in the healing process. It also provides a moist environment that is beneficial for tissue repair.
Now, let's talk about the electronics industry. Electronic components are very sensitive to moisture and oxygen. These gases can cause corrosion and damage to the delicate circuits. That's why our Rust Resistant Film is so popular. It has a high gas - barrier property that protects the electronics from these harmful elements. The film forms a protective layer around the components, keeping them safe from the environment.
But how do we measure the gas - barrier function? There are a few different ways. One common method is to measure the oxygen transmission rate (OTR). This measures how much oxygen can pass through a given area of the film in a certain amount of time. A lower OTR means better gas - barrier properties. We use state - of - the - art equipment to test our films and ensure that they meet the highest standards.
We also look at the water vapor transmission rate (WVTR). Just like oxygen, water vapor can cause problems in many applications. For example, in food packaging, high WVTR can lead to the food becoming soggy. Our films are designed to have low WVTR as well, which helps in maintaining the quality of the product inside the package.
There are different types of materials that we use to achieve good gas - barrier properties. Some of the common ones include polyvinylidene chloride (PVDC), ethylene vinyl alcohol (EVOH), and polyamide (PA). Each of these materials has its own unique properties and advantages. We mix and match these materials in different ways to create films that are tailored to specific applications.
In addition to the materials, the manufacturing process also plays a big role in the gas - barrier function. We use advanced extrusion and coating techniques to ensure that the film has a uniform thickness and a consistent structure. This helps in maximizing the gas - barrier performance.
One of the challenges we face is balancing the gas - barrier function with other properties of the film. For example, we want the film to be strong and flexible at the same time. We also need it to be easy to print on and seal. Through a lot of research and development, we've been able to come up with films that offer a good balance of all these properties.
Our team of experts is constantly working on improving the gas - barrier function of our films. We're always looking for new materials and technologies that can make our films even better. We also listen to our customers' feedback and try to develop products that meet their specific needs.
