DUBHEIntelligent Industrial Ecosystem
Provide more recognizable visual and tactile expressions for printing, packaging, labeling and decoration applications through coloring, surface coatings, microstructured embossing, molded laser and pearlescent materials.
Starting from color, touch, optical changes and surface texture, the specific product is determined based on the base material, adhesive layer and final processing method.
Stable colors are formed through masterbatch, coating or lamination to provide high coverage, translucent or transparent coloring effects.
Create soft touch or wear-resistant protection on the surface to enhance the feel, durability and user experience of high-end packaging.
Use microstructure diffraction to form dynamic brilliance, holographic patterns and anti-counterfeiting vision, which can be used for lamination, labeling and transfer processing.
Create soft pearlescent, bright silver, gold and metallic textures through pearlescent masterbatch, metallic pigments or decorative layers.
Brushed, cloth, leather and artistic textures are presented through embossing, microstructure or surface coating to enhance the layering of materials.
Use glitter particles, optical coatings or multi-layer interference structures to create starlight, flash, rainbow and angle-changing effects.
Color, gloss, texture and viewing angle will jointly affect the final effect. It is recommended to confirm with physical samples and standard light sources.
High coverage, translucent or low gloss effects.
Fine feel, low reflection and wear-resistant surface.
Dynamic diffraction, pattern changes and anti-counterfeiting vision.
Soft reflections, silver gold and metallic textures.
Directional textures, tactile layers and artistic surfaces.
Star points, phantoms and observation angle changes.
The same visual effect can be made into base film, paper lamination, self-adhesive protective film or transfer material, and the structure needs to be determined according to the customer's equipment and substrate.
The color is distributed inside the film material or in the co-extrusion layer, suitable for black, white and stable color base films.
The special effect layer is combined with the BOPP or BOPET base film, and the back is compounded with an EVA adhesive layer, which can be directly heat-coated on the paper.
The back of the special effect film is coated with pressure-sensitive adhesive and equipped with release material, so it can be bonded without heating.
Use rolling, molding or microstructure replication to form brushed, cloth texture, leather texture, laser and 3D effects.
Transfer patterns, metallic or laser vision to paper, leather, textile or other materials via release and effect layers.
Pearlescent or metallic vision can be achieved inside the base film, in a surface coating or in a composite layer.
Special films not only provide visual effects, but also need to meet laminating, printing, laminating, die-cutting, winding and finished product use requirements.
Cosmetic boxes, wine boxes, electronic product boxes, gift boxes and handbags enhance brand recognition and tactility.
Book covers, albums, menus, business cards and publications, available in soft-touch, scratch-resistant, laser, textured and metallic effects.
Daily chemical, beverage, alcohol and electronic product labels support holographic, rainbow, pearlescent, black and color effects.
Self-adhesive color film, starlight film, brushed film and laser film can be used for cold lamination, display boards, signs and display decoration.
Pearlescent, clear colours, glitter and metallic effect materials can be used for flower, gift and festive packaging.
Matte, laser and metal transfer base films are available for surface transfer of textile, leather, apparel and decorative materials.
Special effects usually focus on confirming samples and combine with quantifiable indicators to control batch stability.

Standard status verification date: 2026-07-12. Special effects such as laser, texture, soft touch, and rainbow usually require confirmation samples, corporate standards, and technical agreements as the basis for acceptance.
The visual effects of special films are difficult to fully describe with a single numerical value. Color, feel, texture, and holographic patterns should be confirmed using both standard samples, limit samples, quantitative indicators, and customer process testing. When used in food contact, children's products, outdoor environments or electronic and electrical applications, corresponding compliance tests should also be added based on the complete structure and usage scenarios.
First determine the visual and tactile feel you want to present, and then select the base material, adhesive layer, processing structure and roll material specifications.
Starting from confirming samples, we will establish stable special film specifications based on materials, processing structures and actual customer processes.
