Moisturizing Tissue Paper Structure to Prevent Web Bending
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Moisture-retaining tissue paper products tend to bend and lose their cushioning properties during storage and transportation, making them difficult to package and dispense like general-purpose tissue products, which have higher elasticity and are less prone to bending.
Innovation Solution
A tissue paper product with specific physical properties, including a 2-ply basis weight, thickness, tensile strength, and moisturizer content, is developed, allowing it to maintain softness and smoothness while enhancing cushioning properties, enabling it to be packaged similarly to general-purpose products.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a moisturizer is applied to tissue paper to provide softness and smoothness, then the tissue paper becomes moist and soft, but the web loses elasticity and bends during storage and transportation
Solution Approach 1:
The patent applies parameter changes by precisely controlling the basis weight of the tissue paper within a specific range (12.0 g/m² < basis weight ≤ 13.0 g/m²) and limiting the moisturizer content (0.5 g/m² < moisturizer content ≤ 2.0 g/m²). These parameter adjustments optimize the balance between softness and structural integrity, preventing web bending while maintaining the desired tactile 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 the cardboard case requires increased strength and packaging becomes more complex
Solution Approach 1:
The patent inverts the conventional packaging orientation for moisture-retaining tissue products. Instead of placing products with upper surfaces facing upward, the invention packages them with short side surfaces facing in the top-bottom direction of the cardboard case. This orientation reversal allows the web to function as a post providing structural support, eliminating the need for increased cardboard case strength while preventing web bending.
3Stability of the object's composition
If the orientation of moisture-retaining tissue products is changed for packaging, then web bending is prevented, but the packaging operation becomes troublesome and productivity decreases
Solution Approach 1:
The patent achieves universality by making the tissue product structure itself serve multiple functions. The web not only provides the tissue function but also acts as a structural post for packaging stability. This multi-functionality allows the same packaging orientation to be used for both general-purpose and moisture-retaining products, simplifying packaging operations and improving productivity.
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, preventing bending during storage and transportation, allowing for efficient packaging and dispensing like general-purpose products, even when containing a moisturizer.
Implementation Method 1
the web of moisture-retaining tissue paper is moist and soft due to the hygroscopic effect of a moisturizer

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.
