Cigar Leaf Cigarette Paper for Heating Articles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cigarette paper for cigars has insufficient tensile strength to be applied to heating type smoking articles, leading to damage and a deterioration in unique smoke flavor and taste when used in heating devices.
Innovation Solution
Development of cigarette paper for cigars with 50 wt % or more cigar leaf, incorporating pulp and using a manufacturing method that includes beating and mixing cigar leaf and pulp, followed by papermaking using a Fourdrinier or cylinder paper machine, to achieve a tensile strength of 120 cN/mm or more.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If traditional cigarette paper for cigar is used, then the unique smoke flavor and taste are maintained, but the tensile strength is insufficient causing damage in heating type smoking articles
Solution Approach 1:
The patent applies composite materials by combining cigar leaf fibers with pulp fibers to create a cigarette paper wrapper that achieves both high tensile strength (≥120 cN/mm) and preserved cigar flavor. The composite structure allows the paper to withstand mechanical stress in heating devices while maintaining the unique taste characteristics of traditional cigar wrappers.
Solution Approach 2:
The patent changes the compositional parameters of the cigarette paper by specifying that cigar leaf content must be 50 wt% or more, and tensile strength must reach ≥120 cN/mm. This parameter optimization ensures the wrapper is suitable for heating type smoking articles while preserving the essential cigar flavor profile.
2Reliability
If cigar leaf content is increased to enhance flavor, then the unique smoke flavor and taste are improved, but the tensile strength may be compromised
Solution Approach 1:
The patent optimizes the parameter balance by establishing that cigar leaf content should be 50 wt% or more while simultaneously requiring tensile strength of ≥120 cN/mm. This dual parameter specification ensures both flavor quality and mechanical strength are achieved together, not traded off against each other.
Solution Approach 2:
The composite material structure combines cigar leaf fibers (providing flavor) with pulp fibers (providing strength) in a synergistic ratio. The pulp component compensates for any potential strength deficiencies while the cigar leaf maintains the characteristic flavor, achieving both objectives simultaneously.
3Reliability
If the cigarette paper is made stronger to prevent breaking, then the workability and durability are improved, but the manufacturing complexity increases
Solution Approach 1:
The patent simplifies the manufacturing approach by focusing on key parameter changes: increasing cigar leaf content to ≥50 wt% and optimizing the beating process to achieve ≥120 cN/mm tensile strength. These targeted parameter adjustments achieve durability without requiring fundamentally complex manufacturing processes.
Solution Approach 2:
The patent uses conventional papermaking machinery (Fourdrinier or cylinder paper machine) rather than specialized equipment, effectively copying proven manufacturing methods. This allows the production of high-strength cigarette paper using existing industrial infrastructure, avoiding the need for complex new manufacturing systems.
