The Flat Bottom Coffee Pouch is a type of flexible packaging with a three-dimensional base specifically designed for coffee and high-value food products.  Its core structural feature lies in the multi-folded base that forms a stable support surface, allowing the packaging to stand upright naturally without external support. This packaging format is widely used in the coffee industry, not only for its neat appearance and stable display but also for its significant advantages in capacity utilization, internal space efficiency, and overall packaging consistency. Compared to traditional stand-up pouches or side-gusseted bags, the Flat Bottom Coffee Pouch, with its five- or six-sided stress-bearing structure, maintains even tension after filling, reducing collapse or deformation caused by concentrated weight of the contents. Its structural design also accommodates the needs of industrial mass production, compatible with various composite film material systems, and supports the integration of functional modules such as one-way degassing valves, zippers, and easy-tear openings. In modern coffee supply chains, this type of packaging not only serves as a basic container but is also considered an important component of brand image, information communication, and logistics efficiency, suitable for commercial scenarios requiring high packaging stability, sealing consistency, and standardization.

1. Structural Stability

The Flat Bottom Coffee Pouch utilizes a multi-fold bottom structure. After filling, the bottom unfolds to form a complete support surface, with the bottom width typically exceeding 85% of the bag width. It can withstand static pressure exceeding three times the weight of its contents. Under standard warehousing and stacking conditions, the bag tipping rate can be controlled to below 1%, effectively reducing the risk of deformation during transportation and display. The stable force distribution allows the packaging to maintain a consistent posture during automated boxing and stacking, reducing the frequency of manual intervention and making it suitable for mass production and long-term storage requirements.

2. Capacity Utilization

Under the same external dimensions, the Flat Bottom Coffee Pouch achieves an internal effective volume utilization rate of over 90%, an improvement of approximately 10% to 15% compared to traditional stand-up pouches. After the bottom unfolds, the internal cross-section of the bag is closer to a regular rectangle, reducing dead spaces for content accumulation and allowing for more even distribution of coffee beans or powder. This feature helps achieve higher filling volumes without increasing the external packaging size, reducing the proportion of packaging materials consumed per unit weight of product, and improving overall packaging efficiency.

3. Sealing Consistency

The Flat Bottom Coffee Pouch typically uses a three-seal or four-seal structure at the top, with a heat seal width consistently controlled within 8 to 12 millimeters, and a heat seal strength test reaching over 30 Newtons. The multi-seal structure disperses the sealing force, reducing the probability of single-point seal failure. Combined with a high-barrier composite film, the overall oxygen transmission rate can be controlled to below 1 cc per square meter per day, which helps slow down coffee oxidation and ensures consistent sealing performance across different batches during the storage period.

4. Specification Standardization

The bag dimensions of the Flat Bottom Coffee Pouch are highly standardized. The width, height, and bottom fold ratio can be modularly designed according to common coffee specifications, such as 250 grams, 500 grams, and 1 kilogram capacity ranges, with an error margin of ±2%. This highly consistent specification system facilitates multi-SKU management for brands and also allows for unified planning of automatic filling equipment, labeling systems, and outer carton sizes, reducing production adjustment costs due to packaging differences and making it suitable for long-term stable supply needs.

5. Structural Compatibility

The Flat Bottom Coffee Pouch is compatible with the integration of various functional components, such as one-way degassing valves, zipper closures, or tear-off structures. The installation position accuracy of these components can be controlled within ±1 mm. Its flat front and back surfaces provide a stable mounting area for these functional components, preventing bag deformation from affecting the sealing performance of the components. This feature allows the Flat Bottom Coffee Pouch to flexibly configure functional modules according to the needs of different product lines without changing the main structure, thus enhancing the scalability of the packaging solution.

1. Roasted Coffee Beans

In roasted coffee bean packaging, the Flat Bottom Coffee Pouch can accommodate different weight ranges of coffee beans, from 200 grams to 1 kilogram. The uniform internal space of the bag facilitates natural bean stacking and reduces corner compression. With the addition of a degassing valve, pressure changes inside the bag can be controlled within a safe range, reducing the likelihood of bag expansion. This packaging format remains upright on shelves, making it easy for consumers to identify label information and increasing display density, making it suitable for mid-to-high-end coffee product lines.

2. Ground Coffee

For ground coffee, the regular bottom structure of the Flat Bottom Coffee Pouch helps distribute the powder evenly during filling, reducing localized compaction problems caused by uneven distribution. After sealing, the bag maintains a flat appearance, preventing bulging of the side walls due to powder concentration. In practical applications, this bag type supports multiple opening and closing cycles, allowing users to take out portions as needed while maintaining bag stability after each opening, making it suitable for long-term retail use.

3. Specialty Coffee Series

In specialty coffee products, the Flat Bottom Coffee Pouch is often used to package single-origin or limited-batch products. Its neat and three-dimensional shape helps highlight product information. The flat front and back surfaces provide ample display space for detailed labeling, batch information, and flavor descriptions, making the packaging more systematic in terms of information presentation. In this application scenario, packaging consistency helps establish a professional brand image and meets the market demand for high-quality packaging details.

4. Commercial Channel Supply

In commercial channel supply systems, the Flat Bottom Coffee Pouch is suitable for bulk transportation and centralized warehousing. Its regular shape increases outer carton loading efficiency by approximately 10%, reducing unit transportation costs. The bag remains stable during stacking, reducing the probability of compression damage. For coffee products requiring cross-regional distribution, this packaging format helps maintain appearance consistency at different logistics nodes, reducing after-sales risks.

5. Customized Packaging Solutions

In customized packaging applications, the Flat Bottom Coffee Pouch can be adjusted in size and functional configuration according to different brand needs, allowing for a unified packaging system across multiple product series. Its standardized structure focuses the customization process on surface design and localized functional adjustments, without affecting overall packaging stability. This approach helps brands maintain consistent packaging logic when expanding their product lines, reducing production and management costs associated with frequently changing bag types.
