Glass Bead Technologies for Strength Enhancement

Packaging assembly for securely and efficiently protecting fragile objects like wine bottles during shipping. The assembly uses wedging material like cork balls to hold the objects in place instead of fixed spacers. This allows variations in bottle sizes. The packaging has half-walls with cutouts to fit around the objects. The cutouts create passageways for the objects. The wedging material is placed between the objects and the packaging walls. This prevents contact during transport. The packaging also has an outer wrap to absorb shocks.

Sealant film for packaging materials with improved rigidity, impact resistance, and heat sealability compared to conventional films. The film can be either a single-layer film with an inorganic filler dispersion layer or a laminated film with an inorganic filler dispersion layer and another layer. The inorganic filler is dispersed in a polyolefin base material and treated with a silane coupling agent to prevent aggregation. The filler content in the dispersion layer is 20-40% by mass.

Biodegradable packaging material for honey made entirely from biobased components. The packaging material is a composite of beeswax, natural rubber, and aluminosilicate microsphere. The beeswax provides the barrier properties, natural rubber improves impact resistance, and the microsphere prevents stickiness. The composition balances properties like brittleness and fluidity to overcome limitations of using beeswax alone. The biodegradable packaging provides an alternative to conventional materials like plastic for honey storage that is fully biobased and environmentally friendly.

Packaging system to protect fragile objects like wine bottles during shipping. The system uses cork balls or pieces as packing material inside the container. The cork provides cushioning and insulation to prevent breakage and protect the contents from temperature and humidity changes during transport. The container has half-walls with cutouts to accommodate the objects when assembled. The cork packing wedges the objects in place and provides protection against impacts. The system offers improved packaging protection compared to traditional wooden crates.

Packaging assembly for protecting fragile objects like bottles during transport. The assembly uses a rigid or semi-rigid container and packing material like balls, chips, and cork pieces that wedge the object in place. This prevents bottles from rattling and breaking during transport. The packing material also provides thermal insulation for fragile liquids like wine. The assembly can be implemented in a simple, fast, and adaptive packaging process using a flexible bag and cutouts in half-walls to allow object passage.

A method for making an oriented flexible packaging film using blown film with high filler content. The process involves starting with a blown film made from HDPE resin and at least 50% inorganic filler. The blown film is then oriented to significantly reduce its thickness by at least 35%. This orientation improves the film's mechanical properties like tensile strength while maintaining smoothness for better printing. The high filler content in the blown film allows reducing the amount of expensive HDPE resin, lowering cost.

Multilayer film for packaging materials that provides excellent impact resistance and rigidity by laminating multiple layers containing a specific filler size and concentration. The filler particles are 0.5-5 μm in size, have a loading of 1-20 g/100 g resin in the inner layer, and are contained in an amount of 8 or more layers. This lamination structure improves impact resistance and rigidity compared to single-layer films with aggregated fillers. The filler size and concentration prevent peeling, agglomeration, and point defects while still increasing adhesion.

An oriented flexible film made by reducing the thickness of a blown HDPE film containing at least 50% inorganic filler. The blown film is oriented in the machine direction to a final thickness at least 35% less than the initial thickness. This results in a stronger, thinner, and lower cost oriented film suitable for packaging applications compared to blown films. The inorganic filler reduces the polymer content and cost. Orientation improves strength. The blown film has a lower thickness variation compared to blown films.

Cover tape for packaging chip-type electronic components with improved properties for high-speed peeling, reduced static electricity, and maintenance of strength and transparency during storage and use. The cover tape has a five-layer structure consisting of a conductive heat-seal layer, an intermediate layer with reinforcing particles, an adhesive layer, a cushioning layer, and a transparent base layer. The seal layer is a mixed resin of acrylic-modified polyolefin, tackifier, and thermoplastic elastomer for enhanced peel strength. The intermediate layer has conductive particles and spherical fillers for lamination and cushioning. The tape prevents static and breakage issues when peeling thin electronic components from narrow carriers. The mixed seal resin maintains strength and transparency during storage and high-speed peeling.
