Flat Bottom Coffee Bags are a type of professional packaging bag used for coffee beans and ground coffee.  Their main characteristic is a flat bottom structure, allowing them to stand stably after packaging, enhancing shelf display. These bags typically utilize a multi-layer composite material structure to ensure the bag maintains its shape and the contents remain dry during storage. Flat Bottom Coffee Bags are suitable for various design and printing methods and can showcase brand visuals through different surface treatments. During production, different bag sizes, thicknesses, and sealing structures can be selected according to requirements, making the packaging more suitable for the product's volume and layout. This type of bag offers the advantages of a regular structure and a clean visual appearance, making it suitable for packaging solutions for various coffee product sizes. It is considered a high-quality bag type in the packaging industry, distinct from common stand-up pouches and side-gusseted bags, offering a more three-dimensional appearance and being more suitable for the packaging and display needs of mid-to-high-end coffee brands.

1. Diverse Zipper Options

Custom Zipper Flat Bottom Coffee Bags offer regular zippers, hidden zippers, or tin tie closures to meet different opening experiences. The regular zipper structure boasts a strength of over 2.5N, ensuring the bag maintains its sealing ability even after repeated opening and closing. The Pocket Zipper provides a cleaner front display, enhancing the visual integrity of the packaging. Combined with the stable structure of Flat Bottom Coffee Bags, the mechanical strength of the zipper and its oxygen barrier properties improve overall storage reliability.

2. Multiple Bag Styles

Bag styles can be customized as SUP, Flat Bottom, Side Gusset, or roll film, corresponding to different production line needs. Flat Bottom Coffee Bags utilize a four-corner octagonal structure, increasing shelf display area by approximately 30%. Side gusset bags facilitate increased capacity, while roll film is suitable for high-speed packaging equipment. The diverse bag style options allow customers to design more appropriate packaging forms based on product positioning, ensuring filling efficiency and consistent finished product appearance.

3. Multi-Layer Materials

Available structures include PET/PE, PET/NY/PE, PET/VMPET/PE, OPP/VMPET/PE, and paper/VMPET/PE, with thickness ranging from 60–150μm. The multi-layer composite structure enhances tensile strength and barrier properties. For example, a 15–20μm NY layer can enhance puncture resistance, while the VMPET layer provides superior light barrier effects. The flexible combination of material structures allows Flat Bottom Coffee Bags to be suitable for coffee products with different roasting levels and oil content.

4. Stable Structure

The flat bottom structure achieves stable standing through a wide bottom welding process, with a bottom seam strength of over 3.5N, reducing tipping during transportation. The three-dimensional design increases bag volume utilization, suitable for various capacities such as 250g, 500g, and 1kg. This structure allows the packaging to maintain a three-dimensional effect on all four sides when displayed, helping brands present a more organized visual layout. The bottom structure of Flat Bottom Coffee Bags is also more compatible with automated packaging equipment.

5. Flexible Printing

The entire product can be customized with visual designs, supporting up to 10-color printing with a resolution of 150–200 LPI. The multi-material base film allows for matte, glossy, and spot varnish effects. Brands can adjust the colors, patterns, text, and window placement according to different coffee product lines. The printing precision, combined with the three-dimensional structure of the Flat Bottom Coffee Bags, enhances shelf appeal and maintains packaging consistency.

1. Coffee Roastery

Coffee roasteries need packaging bags for selling coffee beans, drip coffee bags, or ground coffee. Custom Zipper Flat Bottom Coffee Bags support multi-batch packaging, meeting the roastery's requirements for capacity, degassing valve configuration, and printed labels. The flat bottom structure allows for neater display on shelves, improving presentation quality. The multi-layer composite material protects the aroma of roasted coffee beans and is suitable for different roasting profiles.

2. Supermarket Shelves

Supermarket shelves require packaging with high visibility and stability. Flat Bottom Coffee Bags, with their flat bottom design, stand stably, increasing brand visibility. Multiple bag types can be adjusted to different shelf sizes and SKU requirements, better adapting to retail channels. The product can be combined with moisture-proof materials to ensure the coffee remains dry during distribution.

3. Coffee Brand Gift Boxes

Many brands launch holiday gift boxes or limited edition sets, requiring more three-dimensional packaging. Flat Bottom Coffee Bags, due to their sturdy structure and high printing precision, are suitable as individual packaging bags within gift boxes. Brands can use high-color printing, window designs, or different material combinations to present a more distinctive series of visuals, making the gift box more recognizable.

4. E-commerce Coffee Packaging

E-commerce channels have high requirements for packaging strength, transport durability, and product appearance consistency. Custom Zipper Flat Bottom Coffee Bags use multi-layer materials, giving the bags better resistance to compression and damage. The flat bottom structure is easier to stack in shipping boxes, improving shipping efficiency. E-commerce products usually require a good opening experience, and various zipper configurations can enhance the repurchase experience.

5. Coffee Shop Takeaway Sales

More and more coffee shops are offering takeaway coffee beans. Flat Bottom Coffee Bags are suitable for different weight packaging needs. Their stable structure makes them easy to place in the cashier area or display area, improving customer convenience. The material combination reduces the impact of light and air on coffee beans, allowing coffee shops to provide higher-quality takeaway products. Diverse printing options can meet the brand needs of coffee shops for small-batch customization.
