Kraft Paper Coffee Bags refer to packaging bags primarily made with kraft paper as the printable outer layer. They are commonly used for packaging coffee beans, ground coffee, and lightweight dry goods. These bags utilize a multi-layered composite structure, preserving the natural texture of kraft paper while also providing barrier properties against gas, moisture, and light. They come in various forms, including stand-up pouches, flat bags, and flat-bottom bags. The kraft paper surface is ideal for showcasing brand style and allows for various printing designs on the bag. The packaging bags are typically processed with food-grade materials to meet hygiene requirements for food packaging. Kraft Paper Coffee Bags utilize different inner layer materials depending on the contents, ensuring good protection and practicality. Their stable form makes them suitable for mass production and automated packaging equipment, and they are widely used in the coffee industry.

1. Durable

The Aluminum Foil Flat Bottom Kraft Paper Coffee Bag features a multi-layer composite structure. The outer kraft paper layer has a basis weight of 50–80gsm, and the middle aluminum foil or VMPET layer provides excellent barrier properties, with a water vapor transmission rate of less than 0.5g/m²·24h. High strength and good stiffness maintain bag stability during transportation and withstand the standard pressure of automatic filling equipment, reducing bag breakage.

2. High Barrier

The inner material can use PET/AL/NY/RCPP or PET/VMPET/PE structures, reducing oxygen transmission rate to below 1cm³/m²·24h, helping to preserve the flavor of coffee beans. The aluminum foil layer provides high light-blocking performance, protecting the contents from UV rays. Combined with the flat bottom bag structure, the Kraft Paper Coffee Bag maintains the freshness and aroma of the contents.

3. Highly Adaptable

The bag type supports various structures, including SUP, stand-up pouches, and flat bottom bags, suitable for different filling modes. Bag sizes can be adjusted according to the packaging needs of 50g–1kg of coffee beans. The bag opening can be equipped with a tin tie or zipper, allowing for resealing after opening. The overall molding effect is stable, suitable for high-speed packaging lines.

4. Customizable

The product's surface kraft paper is suitable for flexographic, gravure, or digital printing, enabling full-color visual design. Material structures can be selected from combinations such as PET/PE, PET/VMPET/NY/PE, and PET/AL/NY/PE to suit the preservation needs of different contents. The product appearance, bag proportions, and visual layout can all be adjusted according to customer requirements, enhancing brand recognition and making the Kraft Paper Coffee Bag more aligned with market positioning.

5. Easy Sealing

The bag opening can be selected with a tin tie or zipper sealing structure. The tin tie supports repeated folding and fixing, suitable for daily use of lightweight products such as coffee beans and tea leaves; the zipper structure offers higher sealing performance and a tensile strength of 6–8N. The flat bottom structure provides better bag stability, and combined with a heat seal width of 8–10mm, it enhances overall packaging safety, making the Kraft Paper Coffee Bag more stable and reliable.

1. Coffee Shop Outlets

Coffee shops frequently use Kraft Paper Coffee Bags to package freshly roasted coffee beans and their own blended beans. The flat-bottom structure facilitates shelf display, and the outer kraft paper layer makes it easier to showcase brand image. The barrier structure maintains the flavor of the coffee beans, ensuring consumers receive consistent quality after purchase.

2. Roasting Factory Storage Area

When packaging large quantities of coffee beans, roasting factories choose Kraft Paper Coffee Bags suitable for automated packaging lines. Their composite structure can withstand impact during handling and prevent moisture damage during storage and transportation. Different material combinations can be adapted to the preservation needs of light and dark roasted beans.

3. Chain Retail Shelves

Retail supermarkets prefer to use visually consistent Kraft Paper Coffee Bags for displaying specialty coffee on shelves. The flat-bottom bags allow for tight packing, improving the neatness of the display. The bag body can be customized with large-area printing, making the brand more recognizable on the shelves.

4. E-commerce Packaging and Distribution Center

E-commerce companies require packaging that is pressure-resistant, durable, and airtight. The composite structure of Kraft Paper Coffee Bags reduces structural damage during long-distance transportation. The aluminum foil layer protects the contents from temperature fluctuations, ensuring more stable coffee quality during cross-regional delivery.

5. Coffee Training Institution Teaching Materials

Training institutions need to provide students with sample beans during courses. Kraft Paper Coffee Bags can be filled in different sizes and offer excellent sealing and preservation. The bags are suitable for small-batch, portioned management, ensuring consistent flavor of the sample beans throughout the course.
