Hot Stamping for Metallic Package Accents

Microwave-safe food packaging that allows steam to escape automatically during microwaving without peeling or disinfecting. The packaging has a thin silver ink layer inside the film. The ink contains flake-shaped aluminum pigments. The ink is patterned with sections that spark when microwaved. The spark sections have reduced pigment density compared to non-spark sections. When microwaved, the spark sections break down and create steam vents. The ink charges, creates electric currents, and generates Joule heat. The pigment shape, density variation, and charging enable insulation breakdown and venting.

Sorting method for packaging materials like retort containers that have a glossy printing layer containing a glitter pigment. The method involves measuring the angle of reflection intensity at 50% and 20% for the packaging material before and after high-retort processing. The formulas below define the sorting lines: - Passing line: satisfies (d1-d2)/d1*100≤8.0% - Preferred passing line: satisfies (d1-d2)/d1*100≤2.0% The angles d1 and d2 are measured under specific conditions. The method aims to select packaging materials that maintain the glitter appearance after high-temperature, high-pressure sterilization. The sorting prevents changes in metallic luster caused by pigment migration during retort processing.

Laminated packaging material for liquid food products that allows customization of the outer appearance while maintaining integrity and barrier properties. The laminate has a volumetric cellulose layer for holding the liquid, an inner thermoplastic layer for sealing, and an outer thermoplastic layer for protection. The inner layer can have a lower gauge or different cellulose fiber composition compared to conventional laminates. This reduces cost while still maintaining strength and barrier properties. The outer layer can have decorative features like metallization, embossing, or matte finishes. The laminate is manufactured by laminating the cellulose layer with a separator layer, then laminating the thermoplastic layers on either side. This allows customization of the outer appearance without compromising integrity.

A foil stamping process for creating 3D effects on packaging boxes. The process involves two steps: 1) printing proofing to create a stereoscopic foil stamping intaglio and a matched bottom film relief printing plate, and 2) foil stamping pretreatment where the intaglio is mounted on a stamping head, the relief plate is positioned on the box, they're preheated, dusted, and then pressed together to stamp the 3D pattern onto the box. This allows creating 3D effects on boxes using foil stamping with a stereoscopic intaglio and matching relief plate.

Labeled metal packaging container with improved labeling appearance compared to traditional labeling methods. The container has a cylindrical body made of sheet metal, end closure components, and a label applied to the body exterior. The label is crimped onto the body using a technique called "shrink-on" labeling. This involves heating the label material to shrink it tightly around the container body, providing a seamless and attractive label without visible gaps or wrinkles. The label material can be a different material than the body material, such as plastic. The crimping process secures the label in place.

Packaging structure with patterns formed through continuous multi-color hot foil stamping that has increased overall structural stability and can be manufactured in a quick, low-cost and aesthetic manner. The packaging structure has a main body with a re-sealable opening, handles, and a bottom panel. The main body is stamped with continuous multi-color patterns using hot foil stamping. The patterns can be hollowed-out areas, embossed areas, or rolled patterns with elevated and depressed areas. The multi-color stamping is done in one continuous process rather than using separate molds for each color or pattern. This allows faster, more efficient production of complex patterns with improved structural stability compared to separate stamping steps.

A decorative multi-layer extrusion blow bottle with a metallic layer for enhancing the metallic feeling without deforming the metal pigments. The metallic layer is sandwiched between an inner polyethylene layer and an outer layer. The key is using a specific polyethylene resin for the inner adjacent layer with shear viscosity conditions that prevent deformation of the thin metal pigments during extrusion. This allows the pigments to orient in the surface direction, minimizing diffuse reflection and preserving the metallic luster.

Manufacturing process for Heat Transfer labels that allows sequential application of codes between ink and varnish layers to provide protection against wear and friction during transportation and handling. The process involves using multiple layers on the label substrate, including a carrier layer, release layer, protective layer, and an applied layer that can be activated by heat and pressure transfer. This allows the label to adhere to surfaces like metal containers. The sequential code application is done between the layers to prevent wear and damage when the label comes into contact with surfaces during handling and transportation.

A decorative resin composition for multilayer direct blow molded bottles that provides a metallic appearance without using metal coatings. The composition contains a metal pigment dispersed in a blend of low density polyethylene (LDPE) and linear low density polyethylene (LLDPE). The metal pigment has an average thickness of 600 nm or less. When this composition is extruded to form a bottle layer, the metal pigment is rapidly oriented in the extrusion direction. This reduces diffuse reflection and increases specular reflection, giving a more metallic look. The LLDPE component improves metal pigment orientation compared to using LDPE alone.
