Debossing for Impression Package Features

Packaging inserts for products made by an air-laid web process that uses natural fibers and a thermoplastic binder. The process involves generating imprints in the unbonded web, heating it to partially melt the binder and bind the fibers, then cutting the bonded web into inserts with the imprints retained. This allows customized cavities for product fitting without extra processing steps. The imprints conserve shape due to fiber elasticity. The binder can be monocomponent thermoplastic fibers or powder. The air-permeable web is captured on a conveyor and compacted by vacuum.

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.

Shipping packaging with improved impact protection and reduced environmental impact compared to traditional foam-filled envelopes. The packaging has walls with embossed ridges on one side that correspond to depressions on the other side. The ridges join to a smooth sheet, holding them together. This creates a cushioning effect when objects inside impact the walls. The embossing and joining avoids using foam or plastic. The embossed paper provides impact protection while the smooth sheet covers the embossed side during shipping.

A sustainable packaging method that replaces plastic bubble wrap with paper-based packaging articles that have similar cushioning properties. The method involves continuously supplying Kraft paper with a minimum machine direction stretch of 5% at temperatures between 10-40°C. The paper is plastically deformed to form a structured layer with embossments or flutes. This layer is then joined with a flat cover layer to create a compound layer that forms the packaging article. The paper-based packaging has a similar cushioning effect as bubble wrap but without requiring high temperatures or moisture for deformation. The packaging can be formed into envelopes, boxes, etc.

Electron beam curable composition for forming a coating film with matte properties and low migration potential, suitable for packaging applications like food packaging. The composition contains a high content of high molecular weight (meth)acrylate compounds, resin fine particles with 1.5-9.0 µm size, and a low content of low molecular weight (meth)acrylate compounds. The high (meth)acrylate content and large particle size provide matte properties. The low low molecular weight (meth)acrylate content reduces migration. The composition is substantially free of photopolymerization initiators.

Thinner plastic packaging material like shopping bags with improved opening ease. The bags have embossed and flat areas on the film. The embossed areas have irregularities. The flat areas are either non-embossed or have smaller irregularities. This creates friction differences that make it easier to open the bags compared to uniformly embossed bags. The flat areas are strategically placed near the openings to communicate with them. This allows overlapping film layers to separate when opening.

Contact lens packaging with reduced risk of lens damage during transportation and handling. The packaging has a segment of the lid stock that forms an enclosure with the blister packaging and cavity containing the lens and saline. The segment's interior surface has relief elements, like indentations or domes, with the rest being flat. This allows air gaps between the saline and lid surface to prevent contact and leaks during transport and opening. The relief elements are formed by testing the sealed package for leaks using a stamp with matching contours.

Method for handling cigarette packaging material to enable easy opening without weakening the packaging. The method involves embossing the packaging material itself as an opening aid, rather than adding separate features. The embossed lines are formed by pressing into the material to weaken it. This allows the pack to be opened without compromising the seal or integrity of the rest of the packaging.

Molded containers for packaging food items with a matte finish outer surface that is achieved by molding a laminate with a metal foil layer and a single or multiple outer resin film layers. The outer resin film layer(s) contain a polyolefin resin and an olefin-based elastomer. This allows the containers to have a matte finish without using embossed films or coatings that can crack or peel. The matte finish is achieved due to voids generated at the interface between the resin and elastomer layers during molding. These voids create a cloudy appearance in the corners of the container due to differences in refractive index.

Method to manufacture paper packaging with recessed areas for containing items, that reduces wrinkles and microcracks compared to conventional methods. The process involves pretensioning the paper web material before forming the recesses. This prevents wrinkles and allows reliable shaping without excessive stress. The pretensioning step uses clamping jaws and tension rollers to tighten the paper in both directions. The forming step uses a die, hold-downs, and pneumatic pressure to mold the paper into the recesses. The hold-downs are moved to feed the paper during forming to prevent wrinkles. After forming, the recessed packaging is removed from the die. This two-stage shaping process prevents tearing and reduces wrinkles compared to direct molding.
