Cold lamination film is widely used in the field of printed matter protection, and its core composition is derived from transparent PVC material. PVC (polyvinyl chloride) itself has good transparency, weather resistance and certain mechanical strength. After the key process of adhesive processing, it forms a cold lamination film with practical functions. The presence of adhesive gives the cold lamination film the ability to stably bond with the surface of the protected object, which can ensure the convenience of the bonding process and form a lasting adhesion effect after bonding. This combination of material selection and process treatment enables the cold lamination film to adapt to the characteristics of various printed matter surfaces while maintaining its own morphological stability.
Texture classification system of cold lamination film
Based on the difference in film surface texture, cold lamination film forms a relatively clear classification system. Bright film is one of the more common ones. Its film surface has a high glossiness. After covering the printed matter, it can retain the original color saturation and picture brightness of the printed matter to the greatest extent, making the printed content present a more vivid visual effect. Matt film, in contrast, has a lower glossiness and presents a soft matte texture. After covering, it can reduce light reflection, so that the printed matter can maintain clear readability in different light environments, especially suitable for some printed content that needs to avoid strong light interference. The film surface of matte film has a fine granular texture, which not only adds a unique touch to the printed matter, but also has a certain degree of anti-glare effect. At the same time, the particle structure on its surface can also enhance wear resistance. There are also some protective films with special textures. The design of these textures is often targeted at specific usage scenarios or decorative needs, and the changes in texture provide additional visual or functional attributes for printed matters.
Lamination implementation of cold lamination film
The lamination process of cold lamination film does not need to rely on high temperature conditions, and is mainly completed by manual operation or with the help of cold lamination machine. Manual lamination is suitable for some small areas, irregular shapes or scenes with low lamination accuracy requirements. The operator applies appropriate pressure by hand to make the cold lamination film evenly fit on the surface of the printed matter. The operation process is relatively flexible and simple, but it requires certain experience of the operator to avoid problems such as bubbles and wrinkles. Cold laminating machine lamination is suitable for large-scale, standardized laminating operations. Cold laminating machine provides stable and uniform pressure through mechanical devices, which can ensure that the cold laminating film fits closely with the surface of printed products, improve the efficiency and quality stability of laminating, and reduce the errors that may be caused by manual operation. It is a commonly used laminating method for industrial production or batch processing of printed products.
The core protection function of cold laminating film is reflected in the core value of cold laminating film. During daily use and storage, printed products are easily damaged by various external factors. Scratching is one of the common problems. Whether it is friction during transportation or unintentional touch during daily use, it may cause scratches on the surface of printed products, affecting their beauty and integrity. After the cold laminating film is covered on the surface of the printed product, it can form a physical barrier to effectively resist direct scratches on the surface of the printed product by external objects. Dust, stains and other pollutants in the air may also adhere to the surface of the printed product and are difficult to remove. The presence of cold laminating film can prevent these pollutants from directly contacting the surface of the printed product, keeping the printed product clean. A humid environment can damage the paper and ink of printed products, which may cause problems such as paper deformation and ink smudge. Cold lamination film has certain moisture-proof properties, which can extend the service life of printed products and ensure that they remain in good condition for a long time.
Recommended application scenarios of cold lamination film
Print protection is the most recommended application scenario of cold lamination film, covering a variety of printed products such as book covers, posters, brochures, and photos. For book covers, the coverage of cold lamination film can enhance the wear resistance of the cover and extend the service life of the book; posters and brochures, as carriers of information dissemination, often need to be displayed for a long time. Cold lamination film can keep the picture clear and colorful during the display process, and is not easily damaged by the external environment; photos carry important memories, and cold lamination film can protect photos from fading and staining, so that precious images can be preserved for a long time. In addition to being used alone for printed product protection, cold lamination film is also often used in combination with DPI series vinyl film. This combination can give full play to the characteristics of the two materials and form a synergistic effect. In some scenarios with higher requirements for material performance, it can provide more comprehensive protection and more stable performance, meeting the needs of material durability and adaptability in specific environments.
