Paper Packaging Structure With Sealed Gas Pockets for Shock and Insulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current packaging materials are heavily reliant on plastic, which has a negative environmental footprint, and are often a mix of environmentally friendly and non-friendly materials, making recycling difficult, while also failing to provide adequate thermal insulation and shock absorption for e-commerce shipments.
Innovation Solution
A recyclable packaging material made of multiple plies of paper with protrusions that absorb mechanical shock and provide thermal insulation, using improved paper with isotropic elasticity to form sealed gas pockets for insulation and shock absorption, allowing easy recycling without disassembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If plastic-based packaging materials are used, then shock absorption and cushioning are improved, but environmental footprint and recyclability deteriorate
Solution Approach 1:
The patent transforms paper material through dimensional changes by forming three-dimensional protrusions and voids, changing its physical parameters from flat to volumetric structure. This enables the paper to achieve shock absorption properties comparable to plastic while remaining recyclable and environmentally friendly
Solution Approach 2:
The patent creates a composite structure within paper by forming embedded voids and protrusions that create air pockets. This composite of paper material and trapped air provides thermal insulation and shock absorption without requiring plastic layers, achieving multi-functionality in a single recyclable material
2Reliability
If multi-material packaging is used to provide both insulation and protection, then functional performance is improved, but recyclability and ease of disposal deteriorate
Solution Approach 1:
The patent makes the paper material perform multiple functions simultaneously: the protrusions provide shock absorption, the embedded voids provide thermal insulation, and the entire structure serves as protective packaging. This eliminates the need for separate plastic insulation layers and bubble wrap, allowing single-material recycling
Solution Approach 2:
The patent merges shock absorption and thermal insulation functions into a single paper-based structure. The three-dimensional protrusions and embedded voids are formed within the same paper material, combining protective and insulative properties that were previously provided by separate plastic components
3Temperature
If traditional insulative materials are used, then thermal protection is improved, but shock absorption and cushioning deteriorate
Solution Approach 1:
The patent forms three-dimensional protrusions with specific geometric parameters (height, width, spacing) within the paper material. By controlling these dimensional parameters, the structure achieves both thermal insulation through air trapping and shock absorption through the compressible protrusion geometry, simultaneously optimizing both thermal and mechanical protection
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The material effectively dissipates mechanical energy and insulates against thermal transfer, providing enhanced protection for e-commerce shipments while being fully recyclable and reducing environmental impact.
Implementation Method 1
the protrusions can dissipate mechanical energy upon impact
Implementation Method 2
A two-ply packaging material can include a formed ply with protrusions and an unformed ply adhered to the formed ply to seal the protrusions and form pockets of gas within the packaging material that can provide thermal and mechanical-shock protection

AI summary
The disclosed embodiments relate to an insulative protective packaging material constructed using recyclable paper materials. The packaging material includes one or more plies of paper adhered to each other. The one or more plies can have protrusions that form gas pockets. The gas pockets can be sealed by another ply to provide shock absorbency and insulation. Further, the plies can be used in multiple ways such as by nesting the protrusions of one ply into the recessed of another ply, layering multiple plies on top of each other, or individually. Each ply can be substantially flat or have protrusions. The protrusions can be made in various ways such as alternating the directions that they extend and varying the shapes of the protrusions. The resulting packaging material can be used as a shipping container or as liners within shipping containers.
