Deflatable Inflatable Web for Compact Packaging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional protective packaging materials, such as bubble wrap, are volumetrically inefficient for transportation due to their bulky, low-density configuration after manufacturing.
Innovation Solution
A protective packaging web is developed, comprising a first film web with extended portions and a second film web sealed to the first film web around the base perimeter of each extended portion, forming sub-chambers that can be inflated or deflated.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional bubble wrap is manufactured with pre-formed air-filled chambers, then protective cushioning function is achieved, but transportation efficiency deteriorates due to bulky, low-density configuration
Solution Approach 1:
The packaging web transitions from a flat, compact state during transportation to an inflated, voluminous state during use. The chambers are designed to be expanded only when needed, allowing the material to dynamically change its volume and density characteristics based on operational requirements.
Solution Approach 2:
The inflated chambers are nested within a flat web structure during manufacturing and transportation. The three-dimensional protective chambers are contained within the two-dimensional flat web, allowing efficient space utilization during storage and transport, then expanded to provide protection when needed.
2Reliability
If bubble wrap is transported in its inflated, protective configuration, then cushioning performance is maintained, but transportation cost and efficiency worsen due to volumetric inefficiency
Solution Approach 1:
The packaging system dynamically changes its volume from compact during transport to expanded during use. This dynamic transformation allows the same material to serve dual purposes: efficient transportation in compressed form and effective protection in inflated form, eliminating the need to transport pre-inflated material.
3Stability of the object's composition
If the packaging web is designed with sealed chambers, then structural integrity is improved, but adaptability worsens as chambers cannot be deflated for storage or reuse
Solution Approach 1:
The chamber seals are designed to be temporary rather than permanent. The adhesive bonds allow chambers to be inflated for protection, then deflated and re-inflated for reuse. This dynamic sealing capability provides both structural integrity during use and adaptability for storage and repeated use cycles.
Solution Approach 2:
Rather than permanently sealing chambers, the system allows for controlled discarding of air from chambers after use, then recovering the same chambers for subsequent use cycles. The adhesive seals maintain integrity during use but permit controlled deflation and re-inflation, enabling multiple use cycles from the same packaging material.
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 packaging web allows for efficient transportation in a compact, high-density state and can be easily inflated for use as protective cushioning, enhancing packaging efficiency and versatility.
Implementation Method 1
Each of the first film web and the second film web may remain unsealed across the open base region defining regions within the sub-chambers suitable to contain a fluid volume therein. The plurality of sub-chambers may be interconnected via one or more intra-chamber channels, allowing each of the sub-chambers to receive and release fluid in response to external pressures.
Implementation Method 2
The extended surface may be formed at least in part by a plastically stretched portion of the first film web.

AI summary
A protective packaging web is disclosed. The web includes a first film web having a plurality of extended portions including a base perimeter enclosing an open base region and an extended surface protruding in one direction from a plane defined by the first film web. The extended surface has a larger surface area than the open base region. The web also includes a second film web sealed to the first film web around a portion of the open base region to form sub-chambers on a side of the first film web opposite the protruding direction. The first film web and the second film web remain unsealed across the open base region defining regions within the sub-chambers suitable to contain a fluid volume. The plurality of sub-chambers are interconnected via one or more intra-chamber channels, allowing each of the sub-chambers to receive and release fluid in response to external pressures.
