Ink Removal for Fiber Recovery from Packages

Method for accurately aligning dynamic prints on packaging materials with static prints. The method involves removing the static print in predefined sections to reveal the underlying packaging material, creating a negative of the dynamic print inside the static print. A camera detects reference geometries from the static print and the manufactured negative to evaluate quality features like alignment and readability. This ensures proper positioning of dynamic prints despite packaging material variations.

A method for manufacturing a package with a notch using UV laser. The packaging material contains an intermediate layer with titanium dioxide. When the material is irradiated with UV laser, it transforms some of the titanium dioxide into rutile-type titanium dioxide. This discolored area absorbs more UV laser and generates heat. The surrounding packaging material is removed, forming a notch that reaches up to the surface. The UV laser power is 1-100 watts and wavelength is 250-400 nm.

A biaxially oriented polypropylene (BOPP) film with structural color properties without the need for ink printing. The film has a base BOPP layer and an additional structural color layer on top. The structural color layer is made by coating a composite material containing metallic nanoparticles, organic dyes, and a binder on the BOPP surface. The composite material forms a thin film with structural color properties when viewed at certain angles due to light interference. This allows the film to have color-shifting effects without the need for ink printing, providing a more environmentally friendly and cost-effective alternative to traditional BOPP films with printed colors.
