How to choose the right paper bag for tea packaging?

The aroma and quality of tea are highly susceptible to external environmental factors, and the choice of paper bag directly impacts the tea's freshness and flavor retention. Guangdong Guowei Guanli New Materials Co., Ltd., established in Dongguan in 2007 as a “paper-based alternative to plastic” solutions expert, offers sustainable packaging products that provide an eco-friendly and professional option for tea packaging. The following analysis outlines key considerations from multiple perspectives. ​

 

Firstly, moisture resistance and oxygen barrier properties are core criteria. Tea has strong hygroscopic properties; once exposed to moisture, it is prone to mold and spoilage, and contact with oxygen accelerates oxidation, leading to aroma loss. While traditional plastic packaging offers moisture resistance, it does not align with the trend toward environmentally friendly packaging. However, specially processed kraft paper composite bags, a subcategory of Food Packaging Paper Bags, feature an outer layer of durable kraft paper and an inner layer of biodegradable barrier film. This design blocks moisture and oxygen through the film layer while retaining the biodegradable properties of kraft paper, meeting biodegradable packaging standards and extending tea shelf life to over 18 months.  

​

Secondly, odor prevention and breathability must be precisely controlled. Tea has strong adsorption properties, easily absorbing external odors, while also requiring moderate breathability to release stale odors. Kraft paper itself has no odor and moderate breathability. Combined with a multi-layer composite structure, it can effectively block external odors from entering while avoiding the musty odor caused by complete sealing. Guangdong Guowei Guanli's paper bag packaging is optimized for tea characteristics, with some products featuring activated carbon coatings to further enhance odor absorption. A tea company reported a 70% reduction in cross-odor rates after testing the packaging.

 

The suitability of the packaging for specific scenarios requires careful consideration. For tea sold online, the packaging paper bags must have tear resistance. When used as inner bags for courier packing bags, the strength and durability of kraft paper can withstand transportation vibrations and reduce the risk of bag rupture. Additionally, the surface of kraft paper supports processes such as hot stamping and embossing, allowing for the printing of brand logos and tea information, thereby enhancing the product's quality. When displayed offline, packaging paper bags with window designs can directly showcase the appearance of the tea leaves. Combined with the natural texture of kraft paper, they are more likely to attract consumers who value quality.

 

Sealability and convenience of use are also important. Tea leaves require multiple uses, so packaging paper bags must have good sealability to prevent moisture from entering after each opening and closing. Kraft paper composite bags with zippers or self-sealing strips can be chosen, which are convenient for consumers to use while maintaining a sealed state. Guangdong Guowei Guanli's customized products can adjust the sealing strength according to tea categories (such as green tea, black tea, and oolong tea). Green tea requires slightly breathable packaging to prevent moisture buildup, while oolong tea requires stronger sealing to lock in aroma.  

Cost and environmental benefits are worth considering. The initial procurement cost of kraft paper packaging bags is slightly higher than that of ordinary plastic bags, but the unit price can be controlled after large-scale procurement, and it can reduce a company's environmental compliance costs. After a high-end tea brand adopted kraft paper packaging, consumer recognition of the brand's environmental friendliness increased by 40%, and the repurchase rate increased by 25%. Additionally, this type of packaging bag reduces carbon emissions by 68% compared to plastic packaging, aligning with the natural and healthy philosophy conveyed by tea brands. ​

 

In summary, packaging paper bags suitable for tea must strike a balance between moisture resistance, odor prevention, and environmental sustainability. Kraft paper composite bags, leveraging material advantages and process innovations, emerge as an ideal choice that balances practicality and sustainability. Guangdong Guowei Guanli's customized solutions can precisely match the packaging needs of different teas, helping tea companies establish a professional image in the green consumption market.
