Antiblock Systems for Enhanced Film Separation

Environmentally friendly and convenient tissue packaging container that avoids contamination issues and reduces waste compared to conventional containers. The container has a divided interior with a cut groove separating two zones. The container is made by laminating layers of polyethylene, polypropylene, and a shellac polymer. The groove is formed by laser cutting. This allows easy opening without a separate sealing strip. The divided interior prevents adhesive seepage into the tissues. The container can be manufactured in one step by laminating and cutting instead of separate sealing steps.

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.

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.

Heat seal sheet and sterilization package with improved peelability and reduced dust scattering during opening, particularly useful in medical settings where sterile objects are stored. The heat seal sheet has a thermoplastic adhesive layer with an antistatic agent to reduce static cling and improve peelability. The sheet also has low air permeability to prevent lint scattering. The antistatic agent is contained in an amount of 0.5-20 parts by mass relative to 100 parts of the thermoplastic resin. The sheet can be used to seal sterilization packages, with thermally sealed portions having a 180° peel strength of 0.5-15 N/15 mm when opened at 300 mm/min. This provides easy peelability without excessive force that could damage sterilized contents.

Recyclable packaging material made from paper with improved barrier properties for food packaging. The paper has a barrier coating on one side to prevent oxygen or water vapor transfer. The coated side forms the inside of the packaging. The other side is untreated or has a pigment coating for printing. This avoids adding polymer layers to the paper that reduces recyclability. Instead, frame-shaped sealing areas are added to close the packaging. This allows cold sealing without adhesive. A separating layer prevents sticking during roll-up. The paper-only packaging has improved recyclability compared to traditional plastic-coated packaging.

Label design to prevent printing defects and reduce rework when attaching labels to packaging boxes. The label has anti-adhesion layers between the adhesive and release layers. This prevents steps and unevenness when attaching the label since the adhesive and non-adhesive areas are flattened. The anti-adhesion layers are thin, like 1/20 the thickness of the adhesive. They can contain UV ink for printing on the label surface. This prevents printing issues due to the step between adhesive and non-adhesive areas. The label with flattened surfaces reduces the need for reattaching labels due to poor printing.
