Multi-layer Cardboard Technologies for Package Engineering

Cell-based cushioning material that combines the protective function of plastic with the sustainability of paper. The material has a flat structure with deformed, curved cells instead of the usual straight walls. It is made by pressing a flat cell structure to deform the cells. The curved walls provide impact protection without losing shape. The material is suitable for packaging, insulation, furniture, sports mats, etc.

A packaging box for protecting fragile items like lenses during shipping. The box has an internal support cavity that provides cushioning and prevents the item from moving around inside. The box bottom connects to the support piece at one end and the lid at the other end. This allows the item to be placed inside the support cavity, which has curved walls to match the shape of the item, preventing pressure damage from stacked items. The curved walls also provide dust protection. The box is made of integrally formed paperboard.

Corrugated cardboard packaging for cooking appliances that provides an environmentally sustainable and space-saving alternative to expanded polystyrene (EPS) foam packaging. The corrugated cardboard packaging aims to reduce environmental impact, improve recyclability, and save storage space compared to EPS foam. The packaging design uses corrugated cardboard with different densities or layers to provide varying levels of durability and impact absorption for shipping protection. The cardboard packaging is fully recyclable, unlike EPS foam, and can be made from biodegradable materials. It also reduces storage space compared to bulky EPS foam.

Packaging design and method for protecting spinning machine parts during transportation while reducing resource requirements. The packaging has a receptacle to receive and secure the spinning parts. It also has support elements that close cavities in the parts to prevent movement. The packaging is optimized through digital twin planning and production using fiber pulp to form the assignment of parts inside. This provides better protection and density compared to conventional packing.

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.

Pulp mold packaging with improved strength, insulation and stackability for fresh product transportation. The packaging has a main body with a cover that attaches inside the main body. This allows for insulation between the main body and cover. The cover has a top and bottom mold with an internal space. The main body has a top mold with an internal space. The cover and main body molds are made of pulp material with a binder, antifoaming agent, and water repellent. Grooves on the molds prevent distortion. A fixed coupling connects the cover bottom to the main body. This prevents jamming when stacked. The internal spaces between the molds can be filled with cellulose foam insulation.

Eco-friendly packaging solution for heating devices like water heaters and tanks that reduces plastic usage and improves protection during transportation. The packaging uses molded pulp materials like recycled paper to make a base element that surrounds and supports the bottom of the device. The base engages into a pallet and has foldable edges to secure it. This replaces single-use plastic wedges and strapping. A covering element goes on top and side elements on the sides. The molded pulp provides cushioning and stability without plastic, reducing environmental impact compared to expanded polystyrene.

A composite support element for packaging heavy products like white goods that provides durability during transportation and stacking. The support element has a base made from cellulosic materials like urea formaldehyde, melamine formaldehyde, or melamine urea formaldehyde glues. This base is covered by layers of paper. An additional layer of metal can be added between the base and paper layers or outside them to further reinforce the support element.

A fully recyclable cylindrical cardboard container with a manually closable bottom cup to hold liquid dispensing bags. The container is made entirely of cardboard and can be recycled since it doesn't contain any other materials like plastic or metal. The bottom closure is a flexible cardboard cup that can be easily inserted by hand to seal the container around the bag. This eliminates the need for complicated machinery and reduces risks of injury compared to containers with metal seals.

Packaging for elongated products like LED modules that provides high density packaging without excessive material use. The packaging is made from cellulose fiber-based material and has a carrier with transverse walls forming insertion spaces for the elongated products. A foldable casing surrounds the carrier when closed. The products are inserted longitudinally into pairs of openings in the carrier. This allows dense packaging of multiple products without individual wrapping. The foldable casing provides protection and enclosure.

A hanging package for displaying products that is easy to assemble and environmentally friendly. The package has a front portion, a product storage section, and a flap covering the storage section. A thicker reinforcing paper piece is sandwiched between the front and flap. The vertical distance between the front and storage section is slightly greater than the reinforcing paper thickness. Alignment marks help align the folding steps. This allows simple assembly without attaching headers. The thicker paper provides reinforcement.

A lidded egg container that provides improved strength for transporting eggs without breaking. The container has features like an intermediate support between slots, recessed edge supports on the lid, and a central support. These elements enhance structural integrity when closing the lid. The container is made of cellulosic material and can be recycled. It aims to reduce weight compared to traditional containers while maintaining strength. The coated lid further improves hardness.

Mattress packaging that reduces waste and environmental impact by replacing plastic with paper and a coating. The mattress is packed inside a box with at least one layer of paper. The paper has a mass of 80-130g/m2 and a mass ratio of 90-99% paper to 1-10% coating. The coating is weldable material on one side of the paper. This provides strength and tear resistance without plastic. The mattress cover is made of spacer fabric with recesses to reduce weight. The cover has a natural fiber upper layer and synthetic lower layer. The mattress itself has zones for head, neck, shoulders, lumbar, and pelvis support.

Eco-friendly cushioning packaging material made from natural pulp like sugarcane and bamboo instead of plastic or wood pulp. The packaging material is manufactured by processing paper made from the natural pulp. To reduce dust generation from the short fibers of sugarcane pulp, a small amount of bamboo pulp is added during fabric production. The paper surface is coated with starch and biodegradable wax to improve strength and water resistance. This allows replacing traditional plastic cushioning materials with a more sustainable option that reduces plastic usage, carbon emissions, and environmental pollution.

Biodegradable, folding container for batteries that is made from renewable or recycled materials like corrugated paper or cardboard. The container is designed to replace plastic battery packaging that is discarded after each recharge. The folding container allows easy access to the battery terminals for recharging without breaking apart the container. It provides protection and shock absorption during transport. The biodegradable material reduces environmental impact compared to plastic. The folding design reduces waste by eliminating the need for new plastic containers for each recharge. The container can be flattened and reused multiple times.

A cardboard container for food products with a unique shape and sealing mechanism that aims to provide an environmentally friendly alternative to plastic containers. The container has a truncated pyramidal shape with a rectangular base and completely rounded edges. The upper edge folds outward to form a circular flange. This allows the container to be sealed with a transparent plastic sheet on top, providing visibility of the contents. The rounded edges and flange make the containers stackable like plastic containers, but the cardboard construction reduces environmental impact.
