Flex Banner

What materials are mainly used for front-lit, back-lit and shading flexible banners? How are the shading properties, flexibility and durability of these materials?

HANKER's DPI digital printing flexible banner series products, especially for banners with front-lit, back-lit and shading needs, use a variety of high-performance materials, mainly including PVC calendered film, special release paper, and advanced synthetic fiber mesh and waterproof cloth. The selection of these materials is not only based on their excellent printing adaptability, but also on their ability to meet the visual needs under different lighting conditions while ensuring the durability and aesthetics of the banner.
PVC calendered film: As one of the core materials independently developed and produced by HANKER, PVC calendered film has become an ideal choice for making front-lit and back-lit banners with its excellent flexibility and plasticity. Through the precise calendering process, the surface of the film material is flat and smooth, which can perfectly present the details and colors of DPI high-precision printing. In addition, PVC material has good shading properties. By adding specific shading agents, the light transmittance can be effectively controlled to meet the needs of shading banners. In terms of durability, PVC calendering film has the characteristics of anti-aging and strong weather resistance. It can maintain bright colors and is not easy to fade even when used outdoors for a long time.
Special release paper: In the production of backlit banners, HANKER uses specially designed release paper as the base material. This release paper not only has excellent flatness to ensure the accuracy of the printed pattern, but also because of its special coating treatment, it allows light to be evenly reflected and enhances the visual effect of the backlight. At the same time, the release paper is easy to peel off, which is convenient for post-production processing, such as lamination and cutting, and improves production efficiency. Its durability is reflected in its good adhesion to ink and tear resistance, ensuring that the banner is not easily damaged during long-term display.
Advanced synthetic fiber mesh and waterproof cloth: For application scenarios such as outdoor advertising and building packaging, HANKER uses advanced synthetic fiber mesh and waterproof cloth as the main materials for flexible banners. These materials, with their excellent breathability and waterproof properties, ensure the stability and durability of banners under different climatic conditions. Synthetic fiber mesh has good flexibility and tensile strength, and can adapt to various complex installation environments, while waterproof cloth is treated with special coating to effectively block rain erosion and protect the printed pattern from damage. In terms of light-shielding, by selecting dark-colored materials or materials containing light-shielding layers, light penetration can be effectively reduced to achieve light-shielding effects.
In-depth analysis of material properties
Light-shielding: Among the above materials, PVC calendered film and special release paper can achieve different degrees of light-shielding effects by adding light-shielding agents or special coatings to meet the light control needs in different scenarios. Advanced synthetic fiber mesh and waterproof cloth can also provide effective light-shielding performance by selecting dark-colored materials or materials with light-shielding layers.
Flexibility: All materials are carefully selected and processed to ensure their excellent flexibility. PVC calendered film and special release paper show good bending and tensile properties while maintaining high strength, which is easy to process and install. Synthetic fiber mesh and waterproof cloth provide excellent flexibility and elasticity with their natural fiber structure, which can adapt to the installation needs of various complex shapes.
Durability: HANKER's material selection and production process focus on long-term durability. PVC calendering film and special release paper are resistant to aging and weathering, and can resist the erosion of natural factors such as ultraviolet rays, wind and rain. Synthetic fiber mesh and waterproof cloth are specially treated with waterproof and mildew-proof treatment to enhance their weather resistance and service life, and can maintain the integrity and beauty of the banner even in harsh environments.

How is the waterproof performance of PVC tarpaulin banner? Has it been specifically tested for waterproofing?

As a leading global supplier of DPI products, HANKER's PVC tarpaulin banners stand out in many applications for their excellent waterproof performance, becoming the preferred material in exhibitions, displays, points of sale, outdoor advertising and building packaging. This outstanding performance is due to HANKER's deep understanding and innovative application of material science and manufacturing processes.
HANKER's PVC tarpaulin banners use high-quality polyvinyl chloride (PVC) as the main substrate, which itself has good waterproof and moisture-proof properties. However, HANKER did not stop there, but further enhanced the waterproof performance of PVC materials through scientific formula optimization. By adding specific waterproof additives and improvers, not only the water resistance of the material is improved, but also excellent waterproof effect can be maintained after long-term exposure to outdoor environments, effectively resisting rain erosion and moisture penetration.
In terms of production technology, HANKER relies on its two modern production bases and advanced machinery and equipment to achieve full process automation and precision control from raw material preparation to finished product processing. Especially for the production of PVC waterproof cloth banners, multi-layer co-extrusion technology and special coating treatment are used to form a dense waterproof layer, which effectively blocks water penetration. The application of dust-free workshops ensures the cleanliness of the production environment, avoids possible pollution during the production process, and further improves the overall quality of the product.
In order to ensure that each batch of PVC waterproof cloth banners can meet or even exceed customer expectations, HANKER performs a series of rigorous waterproof tests. These tests include but are not limited to:
Static water pressure test: simulates extreme rainfall conditions, and tests the ability of the material to withstand water pressure without water seepage by applying a water column of a certain pressure.
Water immersion test: immerse the sample in water for a long time, observe and record whether there is water penetration, and evaluate its long-term waterproof stability.
Accelerated aging test: simulates environmental conditions of long-term outdoor exposure, such as ultraviolet radiation, temperature changes, etc., to test the changes in the waterproof performance of the material after aging.
Water spray test: Use high-pressure water spray equipment to simulate rain scouring to evaluate whether the waterproof coating on the surface of the material is uniform and effective.
Through these tests, HANKER not only verifies the waterproof performance of its PVC waterproof cloth banners, but also continuously optimizes the production process and material formula to ensure that the product can still perform well under various harsh climate conditions.
HANKER's remarkable achievements in the field of DPI products are inseparable from its continuous efforts in technological innovation, integration of industry, academia and research, and sustainable development.
HANKER has a research and development team composed of industry experts and senior engineers. With strong innovation capabilities and keen insight into market demand, they continue to develop new technologies, new materials and new applications. So far, the company has obtained 20 inventions and utility model patents, which are directly converted into product competitiveness, including the optimization of waterproof performance of PVC waterproof cloth banners.
HANKER actively cooperates with domestic and foreign universities and scientific research institutions to establish an industry-university-research cooperation platform to quickly transform the latest scientific research results into productivity. This cooperation model not only accelerates the development and application of new technologies, but also promotes talent training and technical exchanges, laying a solid foundation for the company's long-term development.
