Laminated Baking Mold Structure for Ink and Grease Barrier
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional baking molds and liners face issues with ink migration and degradation due to moisture and grease permeation, limiting the use of deep, opaque, and vibrant colors, and requiring additional support for self-supporting designs.
Innovation Solution
A laminated baking mold material comprising a metal food contact layer, an exterior paper layer, and a non-toxic adhesive, with a heat-resistant wax seal layer, which prevents ink and moisture migration and allows for deep, opaque, and vibrant printing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If conventional paper or aluminum liners are used with printing, then aesthetic appeal is improved, but ink migration to food product occurs and food safety is compromised
Solution Approach 1:
A food-safe barrier layer is introduced between the printed exterior surface and the food product. This intermediary layer prevents ink migration while allowing the printed design to remain visible, thus maintaining aesthetic appeal without compromising food safety.
Solution Approach 2:
The baking liner is constructed as a composite material system with multiple layers: an exterior layer with printing, a barrier layer for food safety, and potentially other functional layers. This composite structure allows simultaneous achievement of aesthetic appeal, food safety, and functional performance.
2Illumination intensity
If more ink is used for printing on baking liners, then color depth and vibrancy are improved, but ink migration risk increases
Solution Approach 1:
The food-safe barrier layer acts as a mediator that allows use of more ink for deeper colors while preventing migration. The barrier layer blocks the harmful aspect (ink migration) while permitting the useful aspect (color depth) to be enhanced.
Solution Approach 2:
The invention changes the parameter of ink quantity that can be used by introducing the barrier layer. With the barrier in place, the constraint on ink amount is removed, allowing optimization of color depth and vibrancy without increasing migration risk.
3Ease of operation
If thinner paper liners are used, then ease of peeling is improved, but structural support capability deteriorates
Solution Approach 1:
The liner uses a composite structure with an exterior paper layer for peeling and an interior support layer (such as foil or mesh) for structural strength. This allows thin overall thickness for easy peeling while the reinforced interior provides necessary support during baking.
Solution Approach 2:
The liner is segmented into functional layers with different properties: an exterior layer optimized for peeling and an interior layer optimized for support. Each layer performs its specific function, allowing optimization of both peeling ease and structural strength independently.
4Strength
If thicker paper liners are used, then self-supporting capability is improved, but ease of peeling deteriorates
Solution Approach 1:
The composite structure allows the interior support layer to provide self-supporting capability while the exterior layer maintains ease of peeling. The combination of materials with different properties resolves the contradiction between thickness for support and thinness for peeling.
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 laminated material maintains aesthetic appearance and prevents ink migration into baked products, enabling self-supporting and pan-supported designs with enhanced durability and printing capabilities.
Implementation Method 1
the food contact layer serves as a functional barrier to prevent at least one of moisture and grease from permeating through the laminated baking mold material into the exterior layer
Implementation Method 2
the food contact layer serves as a functional barrier to prevent migration of the ink and adhesive into a food product
Implementation Method 3
an adhesive layer to adhesively couple the exterior layer and the food contact layer

AI summary
A laminated baking mold material includes a food contact layer and an exterior layer. The food contact layer serves as a functional layer, and may include an aluminum foil. The exterior layer may include a paper layer, and may be printed. The laminated baking mold may be formed into self-supporting baking molds or pan-supported baking liners. The functional barrier prevents migration of ink from an exterior surface of the baking mold or liner into a baked product or the permeation of grease or moisture from the baked product to the exterior layer preventing a degradation of a printing thereon and allowing for deep, opaque, and vibrant colors and patterns.
