The paper package design consists of lines and folds scored on the sheet, which enables the flat sheet of paper to fold into a robust package for fragile products. The paper neatly folds around the objects in a specific design, which prevents breakage in case of drops. From the top, the design of the folded package resembles a hexagonal shape with filled alternate nodes. This makes horizontal and vertical packing very space efficient. The lines and folds themselves can be scaled to appropriately package different objects.

Delicate products such as eggs are usually packaged in semi-rigid compartmentalized trays. Such products are also stacked for transportation. This type of packaging has an inherent disadvantage as it relies on the rigidity of the item separation mechanism to enable such stacking. Also, such trays allow open access to the fragile/brittle product from above through which they can easily fall out. Thus, there is a need to provide better protection to the delicate products in the form of strong packaging which is economical and easy to carry/transport.
- Stronger package: the specially constructed lines and fold patterns of the structure provided it extra strength despite the fragile nature of the paper itself
- Drop resistant: this package form has performed very well in drop test experiments
- Compact stacking: the design of the package allows highly space efficient horizontal and vertical stacking, reducing wasted transport space
- Space for branding: the packaging has a large enough space to feature advertisements, providing an additional source of income
- Flexible usage: by changing the scale of the folds, it is possible to package not only eggs, but chocolates, flowers and even fast-food take-aways as well
The particular prototype has been made specifically for packaging 3 or 6 eggs at a time. The package is made of lines on the papers which are scores along which we fold, after placing the object, to securely package the item. After the initial folds to secure the objects, another fold compactly packs the payload into a hexagonal form. The shape of the final package now comes into play as they are stacked compactly with similar packages and shipped out.
The technology involves a novel paper or corrugated board package designed specifically for fragile or brittle products like eggs, fruits, bottles, or chocolates. It has undergone basic functional testing such as vertical and horizontal drop tests. The results show that the packaging effectively protects its contents in most cases, indicating a functional, tested prototype stage.

The societal impact lies in promoting sustainable and biodegradable packaging solutions that reduce plastic usage. By offering a cost-effective, eco-friendly, and safe alternative for transporting fragile goods, this invention supports environmental conservation, reduces breakage-related losses, and aligns with global efforts for greener supply chains.
Applications/Domains: This packaging system can be used for transporting delicate food items such as eggs, fruits, and chocolates, as well as small glass bottles. Its stackable and interlocking design makes it suitable for retail packaging, food delivery, and bulk agricultural logistics. The domains include food logistics, sustainable packaging design, and protective transport solutions.
