Packaging Decoration Techniques

Biaxially oriented polyester film with non-slip surface, transparency, and easy winding for use in packaging applications like food containers and top seals. The film has two layers, A and B, both containing polyethylene terephthalate (PET). The dynamic friction coefficient of the A layer surface, the friction coefficient between A and B layers, and the haze are controlled within specified ranges to balance slipperiness, transparency, and processability. The film's non-slip surface prevents stacked containers from collapsing when pressed together.

A method for manufacturing a recyclable and moisture-proof packaging strip that is easy to recycle, has water repellency, low adhesion, and anti-static properties, and is environmentally friendly and moisture-proof. The method involves forming a double coating layer on the inner surface of the paper fabric constituting the packaging strip. The first coating layer is made with an acrylic resin composition. The second coating layer is made with modified calcium carbonate. This provides water repellency, low adhesion, and anti-static properties. The paper fabric with the double coating layer is overlapped and bonded to create a barrel-shaped packaging strip. This eliminates the need for synthetic resin films that can't be easily recycled.

Packaging film for bags and pouches that has improved anti-blocking properties to prevent sticking and clogging. The film has one surface with a roughness of 1-10 microns due to blending iron powder into the propylene resin. This roughness reduces friction and prevents sticking compared to smooth surfaces. The iron powder also absorbs oxygen to improve barrier properties. The rough surface can be formed by blending iron powder into the resin at 1-40% mass.

Multilayer substrate for packaging materials with improved gas barrier properties and adhesion between layers. The substrate has a stretched polypropylene layer sandwiched between an outer layer and an inner coating layer. The coating layer contains a resin with polar groups to improve adhesion of subsequent layers like vapor deposited films. This prevents delamination and improves gas barrier performance compared to polypropylene-only substrates. The multilayer substrate can be used in packaging applications and the packaging material is made by laminating the substrate with additional layers like vapor deposited films and sealant layers.

Coating packaging materials like paper and cardboard with a thixotropic aqueous mixture to improve barrier properties like reducing gas and moisture transfer through the material. The coating composition contains smectite clay, a water-soluble polymer, and a cross-linking agent that links the clay to the polymer. Applying the mixture to a surface and heat treating crosslinks the clay-polymer barrier. This provides coated packaging with improved barrier properties for replacing single-use plastic in produce shipping.

Packaging system for improving the finish of chrysanthemum folding, a traditional Japanese packaging technique. The system uses auxiliary devices to assist in folding the edges of the packaging material before the main folding device. This prevents sagging of the edges during folding. The auxiliary devices form multiple folds in the edges before the main folding device. These folds are spaced apart and extend axially. The main folding device then folds the edges into a final shape.

Functional reinforcing paper with insect repellent, antibacterial, deodorizing, moisture proofing, and freshness maintaining properties for improved packaging quality. The paper has a coating with a functional material like insect repellent, antibacterial agent, deodorant, freshness retainer, or desiccant. It can also be used as a packaging material itself with contact surfaces containing the functional material. The coating enhances strength, water resistance, and oil resistance.

A semiconductor packaging technique that improves reliability of power semiconductor packages, particularly for next generation devices like SiC, GaN, and Ga2O3. The technique involves modifying the solder interface between the semiconductor element and substrate to prevent delamination and cracking. The modification involves using a specific solder alloy composition, thin film stack sequence, and solder geometry to reduce diffusion of elements like Ni and Au into the interface. This prevents peeling and degradation of the bond strength between the semiconductor and substrate during repeated heating and cooling cycles. The modified solder interface provides improved reliability for power semiconductor packages operating at higher temperatures and currents.

Embossed paper packaging material for twist packaging that does not require wax coatings. The packaging material has a base layer made of paper or cellulose that is embossed in sections to allow twisting without cracking. The embossing provides elasticity and flexibility for twist packaging without using wax coatings that can make recycling difficult.

Base paper for metallized paper that provides metallized paper with excellent printability and processability in automatic packaging. The base paper has a resin layer on one side and a pigment coating layer on the other side. The pigment content in the coating is 50-85% by mass. The side with the pigment coating has an Oken smoothness of 300 seconds or more and a dynamic friction coefficient against stainless steel of 0.35 or less. This improves printability and reduces friction when metallizing the paper. The coating layer properties remain after metallization.

A recyclable pouch that can be suspended and reinforced near the hole to prevent tearing. The pouch is made of fibrous material like paper or cardboard. A strip of fibrous reinforcement is added between the front and rear walls of the pouch near the hole. This concealed reinforcement increases strength near the hole where it is susceptible to tearing. The reinforcement can be joined to the walls using heat activated adhesive for added durability.

A lighting container that improves aesthetics by dispersing reflective materials in the container and illuminating them. The container has an outer transparent bottle and an inner opaque bottle with a viscous filling material containing reflective particles. When lit, the particles disperse and reflect the light inside the container. This creates a milky way effect that can be customized by changing the light color. The container seals the top and bottom with covers, and the lighting module is installed at the bottom. The reflective material is injected into the container to distribute the particles evenly.

Pouch-shaped lithium battery cell design that improves sealing and prevents electrolyte leakage when a flexible printed circuit board (FPCB) is used inside the cell. The FPCB has a plating layer on the outer surface that contacts the sealed portion of the pouch. A thermal bonding film is added between the plating and the pouch material to increase adhesion and prevent leakage. This prevents electrolyte escape through the seal when the flexible board extends through it.

Optical waveguide packaging and light source module with improved light propagation efficiency. The packaging has a substrate with a cladding layer and a core exposed on the surface. A metal film surrounds the component mounting area. A light-emitting element is mounted in the area and covered by the metal film. This prevents deformation and misalignment of the core during assembly. The metal film on the sides keeps the core axis fixed while mounting the emitter. The covered area also protects the emitter and waveguide.

Packaging film with improved anti-blocking properties for preventing sticking and clogging of filled pouches. The film has at least one surface with a roughness in the range of 1.0 to 10 μm. This roughness is achieved by blending iron powder into the propylene-based resin layer forming that surface. The iron powder not only improves anti-blocking but also provides oxygen barrier properties. Blending iron powder into the resin layer forms a rough surface with a small friction coefficient that prevents sticking.

Packaging a window shutter case assembly to prevent damage during transportation. The method involves placing cushioning material on the bottom of the box that contains the shutter case. The shutter case is then packaged while sitting on the cushioning material. Breakthrough prevention means are added to the cushioning material where the case extensions meet the top surface. This prevents the extensions from piercing through the cushioning and packaging during handling. The prevention means can be a reinforcing sheet or film with higher shear strength than the cushioning material. The extensions and folded edges are positioned on the cushioning with perpendicular surfaces. A second surface portion is formed on the extension edge near the fold to act as a breakthrough prevention point.

A manufacturing method for a stretch film with high transparency and slipperiness for packaging that provides ease of loading and unloading of packaged products. The method involves laminating separate layers of polyethylene (PE) and polypropylene (PP) films using a lamination machine. The resulting laminated film has the advantages of both PE and PP: high transparency from the PP layer and slipperiness from the PE layer. This provides a wide range of packaging films that combine the benefits of transparency and slipperiness for improved product visibility and easier handling compared to using just PE or PP alone.
