Custom Flat Bottom Coffee Bags with Valve & Side Gusset Zipper | Soft Touch Lamination Coffee Packaging
Product Description
This custom eight-side seal flat-bottom coffee bag is designed for premium roasted coffee packaging, combining structural stability, high-barrier protection, and advanced surface treatment.
The eight-side seal flat-bottom design provides superior dimensional stability, ensuring the bag remains upright during transport and retail display. This structure expands the printable area, making it ideal for brands seeking professional, customized coffee packaging with high shelf visibility.
The bag features a pure aluminum inner lining, effectively blocking oxygen, moisture, and light. This high-barrier structure helps protect the aroma, flavor, and freshness of the coffee during storage and transportation, making it suitable for specialty coffee beans and freshly roasted coffee products.
The built-in one-way vent valve allows freshly roasted coffee to release carbon dioxide while preventing outside air from entering the bag. This controlled gas exchange helps maintain the quality of the coffee after roasting and throughout its product lifecycle.
The side-sealed heat-sealed zipper provides reliable sealing and convenient resealing, allowing consumers to easily open and close the packaging while helping to maintain the freshness of the coffee after opening.
The soft-touch outer film provides a smooth feel and a sophisticated matte finish, elevating the packaging's premium positioning and offering a unique visual and sensory experience for specialty coffee brands.
As a professional coffee packaging manufacturer, we offer customized solutions including bag sizes, printing designs, surface treatment options, valve configurations, and packaging structures to meet the diverse needs of different coffee brands.
Material and Structural Advantages
Eight-Side Sealed Flat Bottom Structure
The eight-side sealed flat bottom structure provides superior mechanical stability, keeping the coffee packaging upright during transport and retail display. Compared to traditional packaging bags, this design offers a larger front display area, which is beneficial for brand promotion and enhances the shelf appeal of premium coffee products.
Pure Aluminum Inner Layer
The pure aluminum inner layer provides high barrier properties, effectively blocking oxygen, moisture, and light. This helps minimize the impact of the external environment on roasted coffee, protecting volatile aroma components and maintaining the flavor quality of the coffee during storage and transportation.
One-Way Exhaust Valve
The one-way exhaust valve is designed specifically for freshly roasted coffee products. It allows carbon dioxide released after roasting to escape while preventing external oxygen from entering the packaging. This controlled pressure release system helps reduce packaging expansion and extends the shelf life of the coffee.
Side-Sealed Heat-Resealable Zipper
The side-sealed heat-resealable zipper provides a secure resealing solution after opening. It improves the ease of use of the packaging while helping to reduce the packaging's contact with air during repeated opening and closing, thus ensuring that the coffee remains fresh after its first use.
Soft-touch film finish
The outer surface is coated with a soft-touch film, providing a smooth feel and a premium matte finish. This surface treatment enhances the visual depth of the printed design and helps coffee brands create a differentiated packaging experience.
