In the world of wine, from the moment a winery carefully brews and bottles it, how to maintain its flavor, aroma, and quality becomes a race against time. Traditional wine preservation methods, such as cork stoppers and screw caps, although effective to some extent, also have their own limitations. Nowadays, the emergence of new non-woven fabrics has brought a new dawn for wine preservation and is quietly changing the landscape of this field.
Material composition and characteristics of new non-woven fabrics
Core Material Unveiling
The emergence of new non-woven fabrics in the field of wine preservation lies in their unique material combination. Biobased materials represented by biodegradable polylactic acid (PLA) occupy an important position among them. PLA raw materials are derived from renewable plant resources such as corn, potatoes, and crop straw, and have good biocompatibility and biodegradability. In new non-woven fabrics, PLA fibers typically account for 40% -60%, providing the material with basic flexibility and stability. For example, in some high-end wine preservation packaging, non-woven fabrics mainly made of PLA can tightly adhere to the bottle body without scratching it due to the hard material.
In addition, the addition of nanocellulose has brought a qualitative leap to non-woven fabrics. Nanocellulose has extremely high specific surface area and excellent mechanical properties. Although its content in non-woven fabrics is relatively small, generally between 5% and 15%, it can significantly enhance the strength and barrier properties of the material. It is like steel bars in a building, supporting the non-woven fabric structure, allowing it to remain stable in the face of external environmental changes.
Excellent feature display
Excellent gas barrier properties: The flavor and quality of wine are highly susceptible to the influence of oxygen and other gases. The new non-woven fabric, with its unique material structure, has excellent barrier properties against gases such as oxygen and carbon dioxide. Experimental data shows that compared with ordinary packaging materials, the new non-woven fabric can reduce the oxygen transmission rate by more than 80%, effectively delaying the oxidation process of wine and maintaining its freshness in fruit aroma and taste. This means that wine packaged with new non-woven fabrics can maintain its original flavor for a longer period of time during the shelf life, reducing problems such as taste deterioration and aroma loss caused by oxidation.
Good humidity regulation ability: Wine storage requires high humidity, and high humidity can easily cause cork to mold, while low humidity may cause cork to dry and crack, affecting sealing. The new non-woven fabric has a unique humidity regulation function, which can absorb or release a certain amount of moisture, stabilizing the relative humidity of the wine storage environment within an ideal range (generally 60% -70%). For example, when the environmental humidity is high, hydrophilic groups in non-woven fabrics will adsorb excess water; And when the environment is dry, it slowly releases moisture to ensure that the wine bottle stopper is always in good working condition.
Antibacterial performance guarantee: Microbial contamination is also an important factor affecting the quality of wine. The new non-woven fabric exhibits excellent antibacterial performance by adding natural antibacterial agents or utilizing the material’s own characteristics. Non woven fabrics containing chitosan have significant inhibitory effects on common microorganisms such as Staphylococcus aureus and Escherichia coli, effectively preventing wine from spoiling due to microbial growth during storage and transportation, and extending the shelf life of wine.
Application forms of a new non-woven fabrics in wine preservation

Direct wrapping: The new non-woven fabric is directly made into a sleeve shape and wrapped around the outside of the wine bottle. This method not only provides physical protection for wine bottles and reduces collision damage during transportation, but also utilizes the gas barrier and humidity regulation properties of non-woven fabrics to create a stable microenvironment for wine. For example, some boutique wineries use this method on the packaging of limited edition wines, which not only highlights uniqueness but also safeguards the quality of the wine.
Built in sandwich type: A new non-woven fabric sandwich layer is set inside the wine packaging box. After the wine is placed in the packaging box, non-woven fabric surrounds the bottle from all sides. This application form is particularly common in bulk transportation of wine, which can effectively reduce the risk of environmental factors affecting the entire box of wine during long-distance transportation, ensuring that every bottle of wine can safely reach its destination.

The new non-woven fabric can also be made into fresh-keeping sheets, which can be placed inside wine bottles or under bottle caps. Fresh food tablets are usually specially treated and contain antioxidants or antibacterial agents that can be slowly released. After being placed in the bottle, the preservative film will continue to release effective ingredients, inhibit the growth of microorganisms that may exist in the bottle, and slow down the oxidation rate of the wine. For example, in some high-end restaurants, sommeliers will put these fresh-keeping tablets into the remaining wine bottles after opening, in order to extend the drinkable time of the wine after opening and maintain its taste and flavor.
Industry changes and prospects brought by new nonwoven fabrics
Positive impact on the wine industry
Improving product quality and stability: Wine preserved with new non-woven fabrics has greater stability in quality. Whether it is long-term cellar storage in wineries, complex and variable logistics transportation processes, or storage stages after consumer purchase, wine can better maintain its original flavor and taste, reduce quality decline caused by improper preservation, and enhance consumer trust in wine brands.
Expanding market and sales scope: Due to the new non-woven fabric, the shelf life and freshness of wine can be effectively extended, allowing wine to maintain high quality in a wider geographical area and for a longer period of time. This provides opportunities for wine companies to expand their markets, and some remote areas that were previously difficult to access due to preservation issues have now become within reach, helping the wine industry further expand its market share.
Future Development Potential and Challenges
Infinite potential: With the continuous advancement of materials science, new non-woven fabrics are expected to further improve their performance. For example, the development of non-woven fabrics with higher selective barrier capabilities for specific gases can more accurately regulate the gas environment inside wine bottles; Or develop non-woven fabrics with self-healing function, which can automatically restore their freshness performance when slightly damaged, providing more reliable protection for wine preservation.
Challenges coexist: Currently, the application cost of new non-woven fabrics in the field of wine preservation is relatively high, which to some extent limits their large-scale popularity. In addition, consumers’ awareness of this new type of fresh-keeping material is not high enough, and the wine industry and material companies need to jointly strengthen market promotion and education. In the future, how to reduce costs, improve production efficiency, and enhance consumer recognition of new non-woven fabric preservation technologies will be the key to promoting their sustainable development in the field of wine preservation.
The new non-woven fabric, as an emerging force in the field of wine preservation, has shown great potential and advantages. It is quietly changing the storage and transportation methods of wine, bringing new development opportunities to the wine industry. I believe that in the near future, with the continuous improvement of technology and the gradual acceptance of the market, new non-woven fabrics will become the mainstream choice for wine preservation, bringing us a more delicious and lasting wine experience.
Dongguan Liansheng Non woven Technology Co., Ltd. was established in May 2020. It is a large-scale non-woven fabric production enterprise integrating research and development, production, and sales.
