Two-Ply Moisturizing Tissue Paper Design to Reduce Packaging Bending
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Moisture-retaining tissue paper products are prone to bending during transportation and storage, making them difficult to package and retrieve due to their soft and moist nature, which differs from general-purpose tissue products, requiring stronger cardboard cases and complex packing operations.
Innovation Solution
A tissue paper product with specific physical properties, including 2-ply sheets with a certain basis weight, thickness, tensile strength, and moisturizer content, packaged in a way that allows it to be stacked like general-purpose products, using a combination of glycerin and 1,3-propanediol as moisturizers to enhance softness and cushioning, and a cardboard case design that accommodates these properties.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If tissue paper contains moisturizer to provide softness and smoothness, then the tissue paper becomes moist and soft, but the web bends easily during storage and transportation
Solution Approach 1:
The patent applies parameter changes by precisely controlling the basis weight (11.7-13.0 g/m²), paper thickness (123-145 μm), and moisturizer content (1.0-2.5 g/m²) to achieve optimal balance between softness and cushioning properties. This quantitative parameter optimization resolves the contradiction by finding the precise range where both softness and structural integrity coexist.
Solution Approach 2:
The patent uses composite materials by combining tissue paper with specific moisturizer formulations containing glycerin and 1,3-propanediol in controlled ratios. This composite structure provides both the softness from moisturizer and the structural strength from the paper matrix, resolving the contradiction between softness and cushioning properties.
2Stability of the object's composition
If moisture-retaining tissue products are packed with upper surfaces facing upward to prevent web bending, then the web does not bend, but a cardboard case with increased strength is required
Solution Approach 1:
The patent changes the packaging orientation parameter from conventional upward-facing to short-side-upward positioning. This parameter change in packing arrangement allows the web to remain stable while distributing weight differently, eliminating the need for strengthened cardboard cases.
3Stability of the object's composition
If moisture-retaining tissue products are packed with upper surfaces facing upward, then the web remains stable, but the packaging operation becomes complex and time-consuming
Solution Approach 1:
The patent inverts the conventional packaging orientation by positioning tissue products with their short sides facing upward instead of upper surfaces facing upward. This inverted approach maintains web stability while simplifying the packaging operation and improving productivity.
4Strength
If the amount of moisturizer is reduced to improve cushioning properties, then the web becomes less prone to bending, but the smoothness and softness of the tissue paper decrease
Solution Approach 1:
The patent applies parameter changes by optimizing the moisturizer content to a specific range (1.0-2.5 g/m²) rather than simply reducing it. This precise parameter control maintains sufficient smoothness and softness while achieving adequate cushioning properties.
Solution Approach 2:
The patent uses composite materials with specific moisturizer formulations containing glycerin and 1,3-propanediol that provide enhanced cushioning properties per unit of moisturizer content, allowing reduced overall moisturizer amount while maintaining softness and smoothness.
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 tissue paper product maintains excellent softness and smoothness while achieving improved cushioning properties, allowing it to be packaged and stored like general-purpose products without bending, reducing packaging costs and simplifying handling processes.
Implementation Method 1
the web of moisture-retaining tissue paper is moist and soft due to the hygroscopic effect of a moisturizer
Implementation Method 2
the web of the tissue paper has a high elasticity... the web 302 is likely to bend in a box during display of the product on a shelf or by a shock during transportation. The web 302 hardly recovers from the bent state.

AI summary
A moisturizing tissue product that can be packaged in the same way as a non-moisturizing tissue product. With this tissue paper product, in which a web obtained by folding and laminating in a pop-up configuration a plurality of sheets of tissue paper containing a moisturizing agent is stored in a rectangular-shaped paper box having an outlet on an upper surface thereof, the problem of the tissue paper is solved by this tissue paper product in which the number of plies is 2.
