Tactile Elements in Package Design

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.

Folding carton for packaging cosmetic products like hair care that has an innovative design to provide a tear-free and leaflet-free packaging solution. The carton has flaps that fold back to expose the product inside. The flaps have creases and arrows printed on them. The arrows indicate where to tear the flaps to access the product. This allows consumers to tear the carton open without damaging the printed product info inside. The carton can be made by gluing the flap to the side panel, folding, and then unfolding to create a rectangular shape with the inner layer inside and outer layer outside. The flaps are then folded again to form the finished carton.

A cardboard packaging box with tamper-evident opening features that allows traces of opening during logistics to be confirmed from the appearance of the box and that can be stacked stably. The box has a main body with an open top and a lid plate, upper flaps connecting the side panels above the opening, and an insertion piece between the front panel and the upper flap. A locking piece folds inside the insertion piece and engages the underside of the upper flap when inserted. This locks the lid closed. If the box is opened, the locking piece remains inside and leaves a visible opening trace. The box also has weakened areas on the lid plate to indicate forced opening.

A reclosable opening device for packaging of pourable products like juice or milk that provides tamper evidence and enables rotation of the cap to indicate if the container has been opened before. The device has a spout, closing element, and cap that are molded directly onto the packaging material. The cap engages the spout to seal the opening initially. Rotation of the cap is restricted due to geometry. If the cap can rotate freely, it indicates the container has been opened before.

Egg packaging lid with improved rigidity to prevent eggs from moving and potentially breaking during transportation. The lid has side walls with serrated projections that can grip knobby surfaces like egg cartons. The serrations are arranged with outer projections, an intermediate projection between them, and a hook on the inner projection. The intermediate projection is longer than half the lid width to provide stability. This prevents simultaneous movement of the outer projections that could damage eggs. Additional stiffening ribs on the edges of the lid can further prevent deformation. The ribs may have protrusions to better grip the cartons.

Hermetically sealed packaging for viscous cosmetics like creams and serums in the form of a pyramid made of foil-coated paper. The packaging has a vertical seam joining the upper and lower sealed ends at 90 degrees. The upper end has a special section with a tear line that initiates opening. This allows easy opening of the packaging by tearing along the initiation line instead of breaking the seals or cutting the corners. The corrugated surface on the sealed ends provides grip for tearing.

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.

Paper-based packaging film with improved light barrier, moisture barrier, and recyclability for food products like butter and margarine. The film has a paper component, a polymeric film, a metallic flake layer printed on the polymeric film, and a white pigment layer between the metallic flake layer and the paper. The metallic flake layer provides light blocking, the white pigment layer enhances paper appearance, and the adhesive between the layers enables clean separation during recycling. The metallic flake grammage is kept low to balance barrier and recyclability.

A food packaging container with a unique design to prevent food from shifting or spreading inside the container while also allowing the contents to be easily viewed. The container has a sloping vessel wall that rises from the bottom all around the periphery, with a height difference of 5 mm or more between the bottom and the upper end of the wall. This prevents the food from moving around or spilling. The sloping wall allows the food to be seen, preventing it from getting hidden or trapped. The container also has legs protruding downward from the bottom to stabilize it. This design eliminates the need for separate internal containers or walls, which can be time-consuming and prone to misalignment.

Refillable cosmetic packaging with improved refill retention and easier refill swapping. The packaging has a cover assembly with flexible tabs around it, and a removable refill container with an axial holding ring. The ring engages the tabs to hold the refill axially in the cover. Rotating the ring in one direction locks it, preventing accidental refill ejection. Rotating the ring in the opposite direction releases the refill. This provides secure retention and easy refill swapping. The tabs prevent clearance between the refill and cover, improving quality perception. The ring engages the tabs to indicate it's locked.

Packaging film for bags and pouches that has improved anti-blocking properties to prevent sticking and clogging. The film has one surface with a roughness of 1-10 microns due to blending iron powder into the propylene resin. This roughness reduces friction and prevents sticking compared to smooth surfaces. The iron powder also absorbs oxygen to improve barrier properties. The rough surface can be formed by blending iron powder into the resin at 1-40% mass.

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.

Smokeless tobacco pouches for oral consumption that improve user comfort by having rounded corners instead of sharp corners. The pouch has discrete seams at each end. The inner seam has an arcuate portion proximal to the pouch, and the outer seam has an arcuate portion distal to the pouch. This provides a more consistent seal strength and prevents sharp corners from contacting the user's mouth when placing the pouch. The rounded corners improve mouthfeel compared to sharp corners. The pouch can be made by forming sheets around the content, sealing them, and then cutting the rounded corners.

Packaging system for improving the finish of chrysanthemum folding, a traditional Japanese packaging technique. The system uses auxiliary devices to assist in folding the edges of the packaging material before the main folding device. This prevents sagging of the edges during folding. The auxiliary devices form multiple folds in the edges before the main folding device. These folds are spaced apart and extend axially. The main folding device then folds the edges into a final shape.
