Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current twisting papers for wrapping confectionery products require high levels of opacifying additives to maintain opacity, which increase costs, and wax penetration affects the barrier properties and twistability, necessitating a reduction in opacifying additives and wax usage while maintaining opacity and stability.
Innovation Solution
A waxed paper substrate with a fibrous base, opacifying additives, and a binder that reduces wax penetration, applied using a metered size press, allowing for lower opacifying additive content and reduced wax usage, enhancing opacity and stability while maintaining twistability and barrier properties.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If high levels of opacifying additives are added to maintain opacity, then the opacity of the paper wrapping is improved, but the cost increases
Solution Approach 1:
A binder is introduced as an intermediary substance between the wax and the fibrous base. This binder forms a barrier layer that prevents wax from penetrating into the paper, allowing the use of lower amounts of opacifying additives while maintaining the desired opacity and barrier properties of the waxed paper wrapping.
Solution Approach 2:
The invention changes the chemical composition parameters of the paper substrate by incorporating a binder with specific properties (affinity for wax, appropriate viscosity). This parameter change enables the system to achieve the same opacity with reduced opacifying additive content, as the binder controls wax distribution and prevents excessive wax absorption that would otherwise require more opacifier to compensate.
2Illumination intensity
If high levels of opacifying additives are added to maintain opacity, then the opacity of the paper wrapping is improved, but the amount of wax needed increases
Solution Approach 1:
The binder acts as a mediator that intercepts wax before it can penetrate into the paper substrate. By forming a protective interface layer, the binder reduces wax loss into the paper, allowing for reduced wax application while maintaining adequate barrier protection and optical properties.
Solution Approach 2:
The binder extracts or captures excess wax at the paper surface, preventing it from migrating into the fibrous base. This extraction mechanism reduces the total wax content needed in the final product while ensuring sufficient barrier performance and maintaining opacity without requiring excessive opacifying additives.
3Reliability
If wax is applied on the paper substrate, then the barrier properties are improved, but the wax penetration in the fibrous base increases
Solution Approach 1:
The binder serves as an intermediary barrier layer between the applied wax and the fibrous base. It has specific affinity for wax, creating a controlled interface that maintains barrier properties by preventing uncontrolled wax penetration into the paper, thus preserving both protection and reducing wax loss.
4Ease of manufacture
If the amount of wax is reduced, then the compostability is improved, but the barrier properties may deteriorate
Solution Approach 1:
The binder creates an efficient barrier interface that maximizes wax effectiveness. This intermediary layer ensures that the reduced wax amount still provides adequate barrier protection, as the binder controls wax distribution and prevents penetration, maintaining reliability with lower wax content for improved compostability.
