Information Display in Product Packaging

Form-fill-seal packaging machine that allows using a common film for different products without needing separate pre-printed films. The machine prints product information on both sides of the film before forming bags. This eliminates the need for different films with pre-printed labels for each product. The printing is synchronized with film transport and can be done with a single printer head. The printed areas are adjacent or integrated to avoid needing separate printer heads for each side. The printer contacts the heated areas for thermal printing.

A method to increase the labeling area on pharmaceutical vials by elevating the label above the vial neck. The method involves attaching an extra component, such as a circular disk, onto the vial body below the neck. This creates a stepped shape with a raised section where the label can be positioned. This allows labeling above the vial neck where conventional labels can't go due to diameter constraints. The raised section provides additional labeling space near the vial closure area. The extra component also serves as a tear strip to destroy the label's electronics after opening, preventing reuse.

Digital printing on the inside of flexible packaging to add unique codes, promotional content, or varying patterns on the inner layers of flexible packaging using a separate digital printing process before lamination. This involves digitally printing on the laminated film rolls before combining them in the lamination process to create the final flexible packaging. A compensator roll is added to the lamination machine to adjust for the thickness variation from the digital printing. This allows precise, customizable inner printing that can vary per package while remaining regular and safe for products.

Automated packaging system that simplifies and speeds up the packing process by using AI to recognize invoices and display contents on boxes. The system opens, folds, tapes, and labels boxes. It scans invoices, identifies items, and displays symbols on the box to match. This allows workers to quickly verify contents without manually checking each item. The system also checks if lower wings are taped before upper taping to prevent mislabeling. By automating invoice recognition and displaying contents, it improves packing efficiency and reduces errors.

A method for manufacturing a container package with increased label display area and faster bonding. The method involves providing an inhibitor layer on one of the films that prevents solvent bonding. When overlapping the films, solvent is applied only to one film. This forms a solvent joint where the films join with the inhibitor layer aligned. The separate regions on either side of the joint prevent bonding. This allows high-speed label joining while increasing display area compared to overlapping labels without inhibitor.

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.

Digital printing apparatus for packaging machines that enables customization of packages without reducing production speed. The digital printing apparatus is integrated into a packaging machine for pourable products like juice. It allows printing customized content onto the packages as they are being formed and filled. This allows customization of some or all of the packages without slowing down the packaging line. The digital printing apparatus is designed to work with high-speed packaging machines and does not impact production rates. It allows customization of packages like juice cartons without needing separate customization lines.

Packaging containers with concealed welds and 360 degree printing for tubes, cans, and flasks. The containers have printed designs on the outer surface that continue around the welded seams. The printing and welding process involves: 1) printing images on sheets with parallel side strips, 2) cutting the strips to match container diameter, 3) forming the sheet into a tube, 4) welding the edges, and 5) cutting the tube at the image. The width of the initial image matches the container diameter, and the side strips have copies of the opposite edge. This allows continuous printing around the container. The width adjustment accounts for shrinkage during printing and welding.

Simultaneous laser marking and vision inspection for food packaging that enables real-time position correction of the laser marking. The system uses an OCR vision module outside the laser scan head to capture the full target image without phase transition. The module detects the marking area location and sends it to the scan head. The scan head adjusts the laser beam angle, direction, and focus to match the marking area position. This allows accurate partial marking on the target without needing separate reading devices or software. The OCR module can also read the marking results in real-time to check for defects.

Encoding packaging containers made of rigid plastics like HDPE, PE, PET, and PP for food storage. The encoding is done during the container production process by deep drawing the initial flat plastic sheet into the container shape. Laser treatment on the tool mold inserts creates tiny codes on the inner surfaces that imprint as codes on the container's outer surface during deep drawing. The codes are invisible to the naked eye but can be scanned to read product info, enable recycling tracking, prevent fraud, etc.

An automated system for manufacturing packaging containers with embedded leaflets that ensures proper placement and adhesion of the leaflets. The system uses a feeding mechanism for the blank containers, an adhesive applicator, a folder-gluer for the leaflets, and detection modules to check for presence of adhesive and leaflets during assembly. The containers, leaflets, and adhesive are transferred together on a conveyor. The first detection module checks for adhesive drops on the container. The second detection module checks for proper leaflet placement. Rejects are generated if either check fails.

Display materials and packaging with printing that can be done by laser. The materials have a layer that allows printing when irradiated with a laser. The printing layer contains pigments that change color when excited by laser light. The pigments can be metals like bismuth oxide. The layer thickness for visible laser printing is 5-200 microns. The pigments are mixed with other resins to form the printing layer. The mixing is done in a way to prevent segregation of the pigments during extrusion. This ensures consistent pigment distribution for uniform printing. The materials are laminated and formed into display packages using techniques like vacuum deposition to create gas barriers. The lamination and forming steps are optimized to minimize shrinkage and deformation. The packaging can have a printed logo or text that is visible through the transparent material. The laser printing is distinct from the unprinted areas due to the pigments changing
