The Transparent 8 Side Seal Pouch For Coffee represents the pinnacle of protective packaging, combining crystal-clear visibility (that builds consumer trust by showcasing coffee quality) with industrial-grade sealing technology (that eliminates leakage risks).

Certified by TÜV Austria OK Compost and EN 13432, this pouch uses a 3-layer PLA/PBAT laminate—a fully biodegradable material under industrial conditions—while delivering barrier performance on par with traditional non-biodegradable coffee pouches. It is ideal for coffee brands prioritizing both sustainability and product protection, particularly in markets like Europe where compostable packaging is increasingly mandated.
Superior Sealing Technology
The 8-side heat-sealed design creates a seal strength of 6-8 N/15mm—a 50% improvement in leak-proof performance compared to 3-side seal pouches. This eliminates the risk of coffee powder leakage, a common complaint with traditional packaging that leads to 8% product waste for coffee brands. Each seal is tested using a tensile tester to ensure consistency, with no weak points that could fail during shipping. The 80-150μm thick transparent film achieves 95% light transmittance, perfectly showcasing the coffee’s color (e.g., the rich brown of medium-roast beans or the pale beige of decaf grounds) and particle size uniformity—key factors that influence consumer trust in coffee quality. The film is also scratch-resistant, maintaining clarity even when stacked with other pouches in distribution centers.
Advanced Barrier Properties
The metallized barrier layer (integrated into the 3-layer structure) achieves an oxygen transmission rate ≤0.05 cm³/m²·day and water vapor transmission rate ≤0.5 g/m²·24h—ensuring coffee remains fresh and aromatic for 12-18 months of storage. This is critical for preserving the delicate flavors of specialty coffees, such as Colombian beans with floral notes, which can degrade within 3 months in low-barrier packaging. The pouch’s -40℃ to 85℃ temperature resistance adapts to diverse supply chains, from frozen storage of cold-brew concentrate to ambient distribution of instant coffee. It also resists oil absorption, preventing the film from becoming cloudy when in contact with oil-rich coffee varieties (e.g., Brazilian beans).
Sustainability Credentials
The 3-layer PLA/PBAT laminate degrades by ≥90% within 12 weeks under industrial composting conditions (per EN 13432), breaking down into harmless organic matter that enriches soil—no microplastics remain. The material is sourced from renewable resources (PLA from corn starch, PBAT from plant oils), reducing reliance on fossil fuels. Heavy metal content is far below EU standards (lead ≤0.01ppm, cadmium ≤0.002ppm), and the pouch uses plant-based inks for printing—complying with REACH and EU 10/2011 environmental regulations. Additionally, the pouch is carbon-neutral in production, with emissions offset through reforestation projects in Costa Rica.
Specifically designed for specialty coffee powder, cold brew coffee concentrate, and instant black coffee, the transparent appearance enhances consumer trust by allowing inspection of the product—reducing “product not as described” returns by 30% for online coffee brands. The 8-side seal structure’s cube-shaped form optimizes warehouse storage capacity by 18% compared to irregularly shaped packaging, as it stacks neatly without gaps. This is particularly beneficial for large-scale retailers and subscription services that manage high inventory volumes. The pouch is also suitable for single-serve coffee sachets (50g) and bulk commercial packs (1kg) for cafes, with customizable sizes to meet diverse needs. Its durability reduces transportation damage rates to ＜2%, a significant improvement over traditional paper coffee bags (which have a 12% damage rate).
We offer full size customization (ranging from 5cm×5cm for sample packs to 30cm×40cm for commercial bulk packs) and seal strength grading (standard: 6 N/15mm for regular coffee; high-strength: 8 N/15mm for heavy or coarse coffee grounds). Brands can choose from 8-color flexographic printing with ±0.2mm precision, enabling semi-transparent brand logos or full-color designs on the transparent background—ideal for brands wanting to balance visibility with branding. We provide free compostability certification documentation to help brands market their sustainability credentials, and offer one-way degassing valve integration (to release CO₂ from freshly roasted beans) and easy-tear notch design (for hassle-free opening). For brands new to compostable packaging, our team provides guidance on storage and handling (e.g., avoiding extreme heat) to maintain pouch performance. We also support small-batch trials (MOQ 800 units) to let brands test market response before committing to large orders.
