Gravure Printing for Premium Package Quality

Integrated printing system for multiple types of flexible packaging materials that allows printing multiple designs simultaneously on a single roll. The system combines print data to optimize roll engraving and ink usage. It manages print data, groups designs with compatible size, color, and complexity, generates roll patterns, and calculates print costs. The goal is to minimize rolls, ink, and materials by finding optimal combinations of designs.

Packaging bottles with embedded letters to provide product details directly on the bottle instead of labels that can't be recycled. The letters are created using embossing, carving, laser, sandblasting, or corrosion techniques to form raised, indented, or etched letters on the bottle surface. This allows product information like ingredients, allergens, and warnings to be permanently molded into the packaging instead of added as separate labels. The embedded letters can be read easily and remain intact when the bottle is recycled.

Eco-friendly PET plastic bottle that allows easy recycling and displays product without a label. The bottle has the product name engraved directly on the front side instead of using a removable plastic label. This eliminates the issue of labels not being properly removed or recycled due to adhesive residue. The engraving provides a permanent and visible product identification without relying on a separate label that can be left behind or not fully removed. The engraving design can be customized to match the brand image.

A method for producing a durable and high-quality structured packaging film with an embossed texture that does not flatten over time. The method involves using a gravure printing process with deep engraved cups on the printing form cylinder. The printing varnish is transferred to the first film web with a well depth of at least 50 µm. This creates a textured pattern on the film. The textured film is then laminated with a second film web to protect the texture. The deep engraved cups on the printing form cylinder provide a durable embossed texture on the film that does not flatten or reset like shallow embossing.

A laser marking system for packaging materials like medicine, food, and cosmetics that avoids issues with erasure, ink smearing, and quality issues compared to conventional printing methods. The system uses a linear or circular transport mechanism to move a laser marking head over the packaging material. The linear system has a feeder, linear rail, and conveyor to move the marking head left/right to mark the material. The circular system has a feeder, rotary transfer device, and ejector to grip, rotate, and eject the material while the marking head marks it. Both systems have a controller to coordinate the transport and marking. The linear system allows marking on vertical packaging, while the circular system allows marking on cylindrical items.

Applying identification features to packing materials like cigarette inner liners using laser engraving to authenticate the processed packaged goods. The method involves using lasers to directly engrave point-shaped elements into embossing rollers according to a defined template. When the embossed packings are scanned using the same template, the point-shaped elements are detected and decoded to authenticate the packaged goods. The laser engraving allows on-line, high-speed, in-situ authentication without adding pre-printed marks or slowing down production.

Method for producing a structured packaging film that provides a high-quality, durable 3D effect on the film without regression or flattening. The method involves gravure printing a structured image onto one side of the initial flat film web. This printed image is then left exposed or covered with thin subsequent layers. By forming the structured area during printing, it can adapt to the shape and not be flattened during subsequent processes like lamination. The structured area is created by a deep engraving in the printing cylinder that leaves wells with at least 50 micron depth. This forms a clearly perceptible structuring when printed. The printed ink layer thickness is at least 30 microns.

Method for manufacturing laminated packaging materials like cartons with enhanced decorative effects at low cost and high speed. The method involves laminating the layers, then imprinting a pattern into the outermost transparent layer using rollers with protrusions. This creates visual or tactile effects on the final packaged product. The patterned rollers can be swapped for different designs. This allows customization of decor without adding costly layers.

Packaging tube with embossed designs on the outer surface, and a manufacturing method to create the tube with embossed designs. The method involves marking the tube material sheet with embossed designs before rolling it into the tube shape. This allows the embossed designs to be formed on the outside of the tube without needing separate printing steps. The embossed designs are created by pressing the tube material between concave-convex surfaces. The embossed tube is then rolled into shape and sealed. The intermediate winding step between marking and rolling helps prevent uneven rolling.

Gravure printing roll for fine pattern flexible packaging that can prevent counterfeiting. The roll has a printing pattern with narrow lines and dots, allowing it to print microscopic anti-counterfeit features on packaging. The pattern is created by etching copper on the roll surface using a laser to expose the lines and dots. The exposed areas are then etched to form deep sink walls inside the lines. This creates raised sink walls surrounded by narrow lines when chrome-plated. The sink walls hold ink in the lines to prevent it from smearing. The roll can print fine lines and dots that cannot be replicated, providing anti-counterfeiting protection for products like food packaging, detergents, and pouches.

Embossing barcodes onto packaging foils like cigarette inner liners for authentication using specialized embossing rollers. The barcodes are embossed into the foil instead of printed, allowing high-speed production. The embossed barcodes are read using devices like smartphones to authenticate the packaging. The embossed barcodes are smaller and harder to discover than printed ones. The embossing rollers have teeth or structures arranged in specific patterns to create arrays of identification marks that can be authenticated by comparing against a template. This allows embedding secure, small barcodes into packaging foils for authentication using embossing rather than printing.

Method to produce packaging films with functional coatings on the inside surface that align with the printed labels on the outside. The method involves printing a register mark on the base film during labeling. When applying the functional coating to the inner surface, an engraved plate with a treatment agent application pattern and a register mark B is used. The treatment agent is supplied to the engraved area with the treatment pattern, and colored ink is supplied to the engraved area with the register mark. This aligns the functional coating and label printing during sealing.

Manufacturing cigarette packaging, in particular for the production of cigarette packaging, individual components of cigarette packaging and outer packaging for cigarette packaging. The manufacturing process involves feeding a material web, a material sheet or a blank made of cardboard to the device, embossing at least one embossing pattern on the material web, a material sheet or a blank made of cardboard for the production of cardboard packaging, and forming a pressure-receiving cylinder of the embossing roll.

Smoking product wrapper with visible engraved patterns that can be seen when the wrapper is curved around a cigarette. The wrapper is made by forming weakened lines inside the material that lose continuity when bent. This creates visible engraved surfaces between the lines. The weakened lines can be formed by partially cutting the material to create contrast between the outer and inner surfaces. The engraved surfaces can intersect or merge to create closed shapes. The wrapping technique allows the engraved patterns to be seen when the curved wrapper is formed around a cigarette.

A method for producing a film for packaging that allows accurate alignment of product display printing with functional coating patterns on the inner surface of the packaging film. The method involves using a register mark printed during product display printing to align the coating pattern application areas with the product display areas. This is done by engraving the coating pattern and register mark areas on the printing cylinder, supplying the coating agent to the engraved coating pattern areas, and supplying ink to the register mark areas. This allows accurate alignment of the product display and coating patterns during processing without affecting the adhesion of the inner sealant layer.
