Surface Materials and Finishes for Packaging

Automatically correcting the arrangement of shingled sliced food portions on a packaging line to improve visual appearance and prevent packaging defects. The method involves using sensors to measure the actual arrangement of the portion on the packaging trough after it's placed there. If the measured arrangement deviates from the target, the upstream portion production, delivery, and packaging units are adjusted to compensate. This ensures the portion length, slice spacing, and position match the target values for optimal packaging.

Biaxially oriented polyester film with non-slip surface, transparency, and easy winding for use in packaging applications like food containers and top seals. The film has two layers, A and B, both containing polyethylene terephthalate (PET). The dynamic friction coefficient of the A layer surface, the friction coefficient between A and B layers, and the haze are controlled within specified ranges to balance slipperiness, transparency, and processability. The film's non-slip surface prevents stacked containers from collapsing when pressed together.

Natural fiber-based transparent composites for food packaging that provide a sustainable alternative to fossil fuel-based packaging materials. The composites are made by UV polymerization of alkene and thiol-based monomers with natural fibers like jute. The UV radiation initiates crosslinking reactions to form a tightly bonded matrix around the fibers, resulting in high transparency (>90%) for packaging applications where visibility of contents is essential. The composites offer benefits of natural fiber composites with improved mechanical properties compared to neat polymer films.

Detecting abnormal packaging of coiled wire using imaging and analysis. The method involves capturing images of the coiled wire's circumferential side and end surfaces. It calculates the average wire inclination angle in blocks of the circumferential image. If an angle deviates significantly from adjacent blocks, it indicates an abnormal packaging condition like submerged or mesh-like coils. This allows accurate detection of packaging issues like protrusions, bowing, and end bending in coiled wire.
