Solution Overview
Problem
The environmental pollution caused by non-biodegradable cigarette paper when cigarettes are discarded is a significant issue, and existing solutions for biodegradable cigarette materials have limitations in terms of physical properties and performance.
Innovation Solution
The use of biodegradable cigarette paper made from polymers like polylactic acid (PLA) and polybutylene adipate terephthalate (PBAT), optionally with additives like calcium carbonate, which provides improved biodegradability, tensile strength, and adhesiveness, and is applied to smoking articles to enhance atomization when heated.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If biodegradable materials are used for cigarette paper, then environmental pollution is reduced, but physical properties such as tensile strength and adhesiveness deteriorate
Solution Approach 1:
The patent employs composite materials by combining biodegradable polymers (PLA, PBAT) with natural fibers (cellophane, rayon, cotton, hemp, or flax). This composite structure allows the cigarette paper to maintain adequate mechanical strength while preserving biodegradability, thus resolving the contradiction between environmental friendliness and physical strength.
2Object-affected harmful factors
If biodegradable materials are used for cigarette paper, then environmental pollution is reduced, but adhesiveness deteriorates
Solution Approach 1:
The combination of biodegradable polymers with natural fibers enhances adhesiveness through the inherent bonding properties of these materials. The natural fibers provide surface characteristics that improve adhesive attachment, while the polymer matrix ensures cohesive strength, together maintaining reliable adhesion in an environmentally friendly format.
3Strength
If conventional cigarette paper is used, then physical properties are maintained, but environmental pollution increases
Solution Approach 1:
The patent changes the material parameters by selecting specific biodegradable polymers (PLA, PBAT) and natural fibers with controlled properties. By adjusting the composition ratios and processing parameters, the cigarette paper achieves physical properties comparable to conventional paper while being environmentally benign, thus resolving the contradiction between performance and pollution.
4Object-affected harmful factors
If biodegradable cigarette paper is used, then biodegradability is improved, but manufacturing complexity increases
Solution Approach 1:
The patent achieves homogeneity by using materials with compatible processing characteristics. The biodegradable polymers and natural fibers are selected to have similar melting points, viscosity ranges, and processing temperatures, allowing them to be manufactured using conventional paper-making equipment without requiring complex specialized manufacturing systems.
