Elevate your coffee packaging with our Compostable Tin Tie Coffee Bags, designed for both freshness and sustainability.
The bags are developed for roasters and coffee brands seeking a kraft-based packaging format with a compostable internal structure. The kraft paper provides the characteristic paper appearance and a printable outer surface for branding, while the inner multilayer structure provides the functional sealing and barrier properties required for coffee packaging. The kraft paper itself is not intended to provide the primary barrier function.
Depending on the required packaging performance, the multilayer structure can be selected according to factors such as expected shelf life, filling conditions, and distribution environment. This allows the packaging to be specified around the actual coffee application rather than treating one material structure as suitable for every product.
The integrated tin tie provides a simple manual resealing mechanism after opening. This makes the format suitable for roasted coffee beans and ground coffee sold through specialty roasters, cafés, retail stores, and other applications where a kraft-paper appearance, manual resealing, and a compostable packaging structure are part of the packaging requirements.
Standard formats can be supplied for common coffee weights, while custom dimensions and material structures are available for brands developing their own packaging specifications. A window can also be incorporated where product visibility is required, subject to the selected compostable structure.
For compostable applications, the complete packaging construction should be considered, including the kraft paper, inner film layers, adhesives, printing, and closure components. FernPack can develop the multilayer structure according to the required compostability specification, with applicable certification depending on the final construction and target market.
For extended shelf-life requirements or long-distance export, a higher-barrier structure may be recommended based on the coffee, filling process, and distribution conditions.
Frequently asked questions
1. What is the structure of compostable tin tie coffee bags?
The bags use a kraft-based multilayer structure, combining a paper outer layer with selected compostable film layers. The kraft paper provides the visible outer surface and printability, while the inner layers provide the functional sealing and barrier properties required for coffee packaging. The exact structure can be adjusted according to the application and compostability specification.
2. Are the bags fully compostable?
Compostability depends on the complete packaging structure, including the kraft paper, inner films, adhesives, printing, and closure components. We can provide compostable multilayer structures based on the required specification, while applicable certification depends on the final construction and target market. For a specific compostability claim, the complete bag structure should be confirmed before production.
3. Can the bags include a degassing valve or a window?
A window can be incorporated into the bag where product visibility is required. A PBS/PLA degassing valve can also be considered for roasted coffee applications, but its compatibility with the selected compostable structure should be evaluated as part of the complete packaging specification.
4. Are these bags suitable for roasted coffee?
Yes. They are designed for roasted coffee beans and ground coffee where a kraft-based, resealable packaging format is required. The appropriate multilayer structure should be selected according to the expected shelf life, filling conditions, and distribution environment. For extended shelf-life requirements or long-distance export, we can recommend a higher-barrier structure based on the specific application.
5. How does the tin tie closure work?
The tin tie provides a manual resealing method by folding the closure over the top of the bag after opening. It does not provide the same type of hermetic reseal as a heat-sealed or zipper closure, so the packaging format is generally selected where convenient manual resealing is part of the intended use.
