Heat Transfer for Durable Package Graphics

Method to produce a machine-readable identifier on packaging films that can be easily and quickly produced, easily detect manipulation, and work on opaque films. The identifier is created by selectively absorbing a focused light beam into the first layer of the film, causing a color change and local heating. This heat transfers to the second layer, forming a visible image there. The first layer identifier can be optically read, then the second layer image is read and compared to verify the packaging.

A packaging film with an anticounterfeit image that is suitable for pharmaceutical, nutraceutical, or food packaging. The film has a thermoformable substrate coated with an adhesive layer to receive a transfer image. It also has a low anchorage carrier film with wax coatings that allows easy transfer of the image to the substrate. The wax coatings resist high temperatures and have characteristics for embossing and image release. The film provides a robust and tamper-proof packaging option.

A method for producing structurally colored polypropylene packaging film without solvents or inks. The method involves heating the molded surface of a polypropylene heat-sealing film using a heated roller. A template with desired color information is then pressed onto the heated surface using hot rollers, transferring the image to the film. This allows creating structurally colored packaging film without ink or printing. The heating prevents whitening and fogging. The film has good sealing properties and shrinkage.

Stamping foil for eco-friendly paper packaging that can be recycled by separating the transfer film and paper. The stamping foil allows printing on paper without using plastic films, which can be difficult to separate and recycle. The foil uses a heat transfer process to stamp designs onto paper without adhesive. The foil can print UV inks on the stamped paper surface. It has a releasable layer that enables easy separation from the paper for recycling. The foil also has a protective layer mixed with vinyl resin to prevent moisture damage and improve abrasion resistance. The foil composition and thickness are optimized for stamping and ink adhesion.

Multilayer microstructure transfer film for packaging cartons that allows high-resolution microstructure patterns to be transferred onto paper-based packaging without issues like VOC residue and crease bursting. The film has multiple layers including a transparent microstructure layer and a reflective layer. The microstructure layer has a top surface covered by the reflective layer. This allows the microstructure patterns to be transferred onto paper cartons using the film without issues like residual VOCs or crease bursting.

Tobacco packaging that allows visual effects without additional printing. The packaging uses transparent regions created by heating specific areas of the polyolefin fiber layer in the outer wrapping. This selective transparentization allows designs or branding to be seen through the package without needing separate printing.

Heat shrinkable film for decorating squeeze bottles that sticks well to the bottle surface, doesn't distort during shrinking, and provides a fully enclosed design without falling off during use. The film has specific shrinkage ratios in width and length directions to prevent lifting near the cap. It adheres to the entire bottle surface including the cap and bottom. This allows printing information, patterns, and designs on the film that can be shrunk onto squeeze bottles for a fully enclosed decorative packaging. The film is wrapped around the bottle, heat shrunk, and then opened to provide a sealed, printed squeeze bottle with an intact bottom.

Air cap packaging sheet with printed patterns that can be transferred to the outer surface without affecting the packaged item. The sheet has an embossed structure with air caps. It has a transparent film adhered to one side of the embossed film, and a base film adhered to the other side. Patterns are selectively transferred to the embossed film or base film surface using a roller. This allows printing on the outer surface without contact with the packaged item. The patterns can be roughened surfaces or diffusely reflected areas. The manufacturing process involves extruding the films, embossing, transferring patterns, and heat sealing the embossed and base films together.

Transparent thermal packing sheet and packaging container that allows printing directly onto the packaging without labels. The sheet has a recording layer containing a thermal coloring material that changes color when heated. The packaging container has a similar layer. By sealing the container, the recording layers can be hot welded together, causing the coloring material to activate and reveal the printed information. This allows printing on the container during packaging instead of using separate labels.

Pouch film for heat-sealable packaging applications that allows hidden watermark patterns to become visible when sandwiched between two films and heat-sealed. The pouch film has a front and back surface with a transparent base material and a heat-sealing layer. A watermark pattern is formed by extruding and laminating the heat-sealing layer onto the base material, then contacting a mold to heat only the molded area. This forms a transparent portion of the heat-sealing layer that disappears when sandwiched and heat-sealed between two films, hiding the watermark. This allows patterns to be read before sealing but disappear after sealing to prevent interference.

Printing system, method, and wrapping film for printing on embossed or textured packaging films without blurring or ink peeling. The system involves pre-smoothening the embossed areas of the film using a heating device before printing. This flattens the irregularities and provides a consistent surface for transfer printing. The smoothed areas are then printed using a transfer method like thermal transfer. This prevents ink fade, blurring, and peeling on the embossed sections of the packaging film.

Roll-to-roll registered hot foil stamping/printing on flexible packaging film or laminate to incorporate decorative patterns, text, pictures, or holograms on flexible packaging materials like food wrappers, labels, or bags. The process involves unwinding the packaging film, applying a hot foil web, stamping/printing the design using a press, and rewinding the printed film. It allows continuous, registered hot foil stamping/printing of flexible packaging materials using roll-to-roll processing.

Automatic packaging sealing machine that can automatically print and seal products using hot melt printing for accurate and indelible marks. The machine has a feeding mechanism, conveyance, printer, and discharge unit controlled by a motor. Sensors detect when the packaging is properly seated for printing. This allows automated feeding, printing, and discharge of sealed packaging. The printer uses hot melt transfer to avoid erasure issues. The machine also has adjustable feeding and printing height to accommodate different packaging.

Stainless steel insulated double-wall bottle with improved impact resistance and decoration capabilities. The bottle has an inner and outer cylinder with vacuum between them. It aims to prevent deformation of the outer cylinder during impacts that can damage the vacuum layer. The solution involves a shock-absorbing layer sandwiched between the inner and outer cylinders. This layer absorbs impacts and prevents deformation. For decoration, the bottle allows direct transfer of patterns onto the stainless steel surface, eliminating the need for painting. This is achieved by specific surface treatments to enable direct transfer without compromising the vacuum seal.
