Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a convenient and equipment-free method to wrap food items like snack bars at home, as existing solutions such as metal foil and plastic wrap require additional tools or heat sealing machines.
Innovation Solution
A precision scored laminate wrapper with a flexible bottom layer and top layer, adhered by a pressure-sensitive adhesive, allowing for easy removal of peripheral portions to create an adhesive perimeter for airtight packaging without requiring any equipment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If metal foil or plastic wrap is used to wrap food items at home, then the wrapping function is achieved, but additional equipment or tools are required
Solution Approach 1:
The wrapper integrates multiple functions into a single structure: the flexible layer provides containment, the adhesive layer provides sealing, and the scored portions provide structural definition. This merging eliminates the need for separate tools like foil, plastic wrap, and heat sealing machines, allowing consumers to wrap food items using only the wrapper itself.
Solution Approach 2:
The wrapper is designed to be self-sufficient and self-operating. The pressure-sensitive adhesive automatically bonds when the wrapper is folded around the food item, eliminating the need for external sealing equipment. The scored portions automatically define the wrapper structure, requiring no additional tools to shape or form.
2Reliability
If heat sealing machines are used to seal wrappers, then airtight packaging is achieved, but equipment and complexity are increased
Solution Approach 1:
The patent replaces the mechanical heat sealing system with a pressure-sensitive adhesive system. Instead of using heat and pressure from a sealing machine to bond the wrapper, the pressure-sensitive adhesive provides bonding through simple pressure applied during folding, eliminating the need for complex thermal sealing equipment while maintaining reliable sealing.
Solution Approach 2:
The invention changes the sealing mechanism from thermal (heat-based) to mechanical (pressure-based). The pressure-sensitive adhesive layer activates through applied pressure rather than heat, fundamentally changing the sealing parameter from temperature-dependent to pressure-dependent, which eliminates the need for heat sealing machines.
3Ease of operation
If a precision scored laminate wrapper is used, then equipment-free wrapping is achieved, but the structure and manufacturing complexity increases
Solution Approach 1:
The wrapper is segmented into distinct functional layers: a flexible layer for containment, an adhesive layer for sealing, and scored portions for structural definition. This segmentation allows each layer to be optimized independently during manufacturing while simplifying the final consumer use, as each segment performs its specific function without requiring complex integration.

AI summary
A ready-made wrapper that can be used at home to wrap an article such as a snack bar and a method of making same is provided. The wrapper is a precision scored laminate comprising a flexible bottom layer adhered to a flexible top layer at least in part by a pressure sensitive adhesive (PSA). In one embodiment the bottom layer is scored so that one or more peripheral portions of the bottom layer can be removed and discarded, leaving a wrapper having an adhesive perimeter. After an article is placed in the center of the wrapper, the wrapper can be folded around the article to create an airtight package.
