Benefits of plastic film in surface treatment
Surface treatment is a key process in plastic film manufacturing. It involves modifying the surface properties of a film to enhance its performance and functionality. Surface treatment has many benefits, making it an important step in the production process.
1.Improved Adhesion
After treatment, the film surface becomes more receptive to paints, inks, and adhesives. This enhanced adhesion ensures that these substances adhere securely to the film, preventing any peeling or delamination issues. This is particularly important in applications where the film is used as a printing, laminating, or bonding substrate.
2.Improved Wettability
Untreated plastic films typically have a low surface energy, which makes it difficult for liquids or coatings to be evenly distributed across their surface. However, by surface treating the film, its surface energy is increased, allowing it to better wet and distribute liquids. This is particularly beneficial in applications where a protective layer needs to be applied or for packaging that needs to contain liquids.
3.Improved Printability of Plastic Films
Untreated film surfaces can be smooth and non-porous, making it difficult for inks to adhere and dry properly. However, after treatment, the film surface becomes more porous and more receptive to inks, resulting in clearer, more vivid prints.
This benefit is particularly important in industries such as packaging and labeling, where high-quality printing is critical to product branding and identity, and can even determine the direction of a company’s growth.
4.Enhanced film barrier properties
Plastic films are often used as a barrier layer, protecting products from moisture, oxygen and other external factors. However, untreated films may have microscopic defects or surface unevenness that affect their barrier properties.
By surface treating the film, these defects can be minimized, resulting in a smoother, more uniform surface. This in turn improves the film’s ability to act as an effective barrier layer, ensuring the protection and preservation of the packaged product.
5.Enhance film durability and resistance to environmental factors
Untreated films are susceptible to degradation due to UV rays, moisture, and other harsh conditions. However, by treating the film, its surface is modified to resist the outside elements, thereby extending its life and overall performance.
This is especially important for applications where the film is exposed to outdoor conditions or needs to withstand frequent handling and transportation.
In summary, surface treatment plays a vital role in improving the performance and functionality of plastic films. It can improve adhesion, wettability, printability, barrier properties, durability, and resistance to environmental factors.
These benefits make surface treatment an important step in the manufacturing process, ensuring that plastic films meet the specific requirements of various industries. By investing in surface treatment, manufacturers can produce high-quality films that perform well in their intended applications.
