How Coffee Packaging Impacts Flavor and Freshness? What You Need to Know

Coffee is one of the typical representatives of global beverages. From planting to becoming a drink, every link affects its final flavor. If you want to retain the flavor of coffee, the transportation of finished products is essential. This article will elaborate on what kind of coffee packaging to choose what kind of preservation technology to use to keep the freshness of coffee, and the advantages and disadvantages of various bag types in practical applications.

Is It Important to Keep Coffee Fresh?

Yes, it is important to keep coffee fresh.
The coffee’s flavor will affect the coffee’s overall quality and thus determine the market and price of coffee, so choosing a packaging bag with good sealing performance is particularly important for keeping coffee fresh.

Πώς επηρεάζει η συσκευασία τη φρεσκάδα του καφέ;

Four factors that affect the freshness of coffee: temperature, humidity, oxygen, and light.

• The influence of temperature: High temperature will accelerate the oxidation of coffee and make it lose its aroma.
• The influence of humidity: In a humid environment, the moisture in the air is easily absorbed by coffee, resulting in mold or fermentation, which changes the taste of coffee.
• The influence of oxygen: Coffee will accelerate oxidation due to excessive exposure to the air, thus affecting its unique taste and flavor; too strong humidity will cause bacteria to grow, making the coffee moldy and inedible.
• The influence of ultraviolet rays: Ultraviolet rays in light irradiation will accelerate the decomposition of sensitive components in coffee, thus affecting the taste of coffee.

What is The Best Packaging for Coffee?

Mainstream packaging bags allow coffee-sealed packaging bags to have more shapes, styles, colors, and materials. So which packaging bag should be chosen?

The emergence of composite materials and the invention and use of one-way air valves have completely changed the packaging of coffee bags. The use of composite materials makes coffee packaging have stronger barrier properties, and the design of one-way air valves allows the carbon dioxide released by the coffee beans inside the package to be discharged in time, effectively preventing the packaging bag from bursting due to high air pressure.

At the same time, the air outside the package cannot enter. Therefore, the combination of composite materials and one-way air valves is the perfect choice for coffee packaging bags.

What Are The Types of Coffee Packaging Bags?

Side-seal Bag

Side-seal bags are sealed on all four edges of the bag to form a closed internal environment, which can maintain the stability of the internal environment of the package. Four-sided sealed bags are mostly made of multi-layer composite materials, which have excellent moisture resistance and light-shielding properties. With the use of a one-way air valve, the internal gas of the package can be discharged in time to prevent the bag from bursting. In addition, the side-sealed bag can be equipped with a zipper and a tin bar to facilitate secondary sealing after opening, reducing food waste caused by improper sealing after opening.

• Advantages: strong stability and easy to stack and store.
• Limitations: high cost.

Three-side Seal & Back Seal Bag

This bag type has no bottom support, but it can also be equipped with one-way air valves, zippers, and other devices. Three-sided seal, back seal bagged coffee often uses high barrier materials such as pure aluminum or aluminized film to enhance protection performance, which is more suitable for brands that need cost-effective solutions.

• Advantages: Because of the low price, it is more suitable for large-scale production.
• The material can be customized according to the protection level.
• Limitations: There is no reinforced bottom support, and it is not easy to stand upright.

Stand Up Bag

Because the stand-up bag has a large flat surface at the bottom, it forms a stable bottom support, allowing the bag to stand on its own when filled with items, making it convenient for display and storage. Stand-up bags mostly use a multi-layer composite structure, which can be equipped with one-way air valves, zippers, and other devices according to needs, and also have a good sealing effect.

• Advantages: convenient display, materials can be flexibly customized
• Limitations: high cost

Comparison and application scenarios of various bag types:

Each type has its unique features. Coffee manufacturers can choose the appropriate packaging bag type based on their packaging costs and market positioning.

For example: instant coffee powder can choose three-sided sealed bags or back-sealed bags. For coffee in the high-end market, eight-sided sealed bags or stand-up bags can be selected. At the same time, the concept of green environmental protection has gradually become popular, and the use of degradable and recyclable materials to make coffee bags has gradually become an industry trend, which not only meets the need for freshness preservation but also reflects the social responsibility of enterprises.

The design concepts and manufacturing processes of different types of coffee bags directly affect their performance in coffee preservation. Whether you are a professional roaster or a home user who enjoys coffee every day, you can choose the most suitable packaging solution according to your situation. In the future, Συσκευασία Huiyang looks forward to seeing more innovative coffee bag types appear, further improving the quality of coffee and consumer satisfaction. At the same time, the coffee industry should also actively respond to the call for sustainable development and strive to develop a new generation of packaging materials that meet the preservation standards and are conducive to environmental protection.
