Professional Heat-Sealing Efficiency: Say goodbye to stapled bag folds or weak tape closures. These high-performance food bags are explicitly manufactured to support heat-sealing bars. The specialized plant-based lining requires a significantly lower sealing temperature than standard oil-based plastic bags, allowing busy operators to create an air-tight, tamper-evident barrier while conserving energy during fast production runs.

Artisan Presentation with Zero Petroleum: Traditional clear window liners rely on crude oil-derived plastics that pollute the ecosystem. Our premium heat-seal bags pair rustic, eco-conscious brown kraft paper with a high-clarity NatureFlex™ window panels constructed from managed forest stocks. Your multi-layered bloomer sandwiches, artisanal wraps, pastries, or gourmet slices of cake are showcased beautifully without any synthetic condensation fogging up the glass-like viewing strip.

The Ultimate Food-To-Go Pairing: Engineered for high-volume coffee shops, bakeries, school cafeterias, and commercial catering passes. These flat-pack bags are designed to seamlessly accommodate rigid sandwich card inserts and sofa trays. Simply slip your loaded product into the bag, slide it across the heat bar, and hand over a perfectly protected, beautifully branded retail package that customers can open with complete trust.

• Low-Temp Heat Sealable: Specifically optimized to melt smoothly under impulse heat-seal bars to create an airtight freshness barrier.
• Crystal Clear NatureFlex™: Premium anti-fog observation window manufactured entirely from natural, sustainable wood pulp cellulose.
• Perfect Tray Compatibility: Sized beautifully to hold standard N1 sandwich and cake sofa trays, protecting items from crushing during transit.
• 100% Petroleum-Plastic Free: Fully aligned with Feed a Field™ criteria and Made in Green Britain™ eco manufacturing protocols.
• Energy-Smart Production: Low melting matrix requires less operational wattage from countertop impulse sealing units.

Because our heat-sealable packaging relies on natural wood pulp elements, maintaining optimal storage conditions ensures long-term operational performance:

• Temperature Boundaries: Store within a climate-managed room between 17°C and 23°C (60°F to 75°F). Avoid keeping them next to heat sealer passes or kitchen radiator pipes when inactive.
• Keep It Dry: Always protect the unbleached kraft paper fibers from heavy sink steam, damp storage environments, or wet floors.
• Out of Direct Sunlight: Keep the bulk stock enclosed inside original shipping boxes to prevent UV radiation from drying out or degrading the flexible plant film window.
• Observe Shelf Lifespan: We recommend putting these natural cellulose bags into service within 6 months from your initial delivery date.

• Material Base: Sustainable Premium Kraft Paper sourced from certified responsibly managed forestry.
• Window Composition: 100% Clear Renewable Wood-Cellulose NatureFlex™ Film Panel.
• Chemical Profile: 100% Plastic-Free, Chlorine-Free, and Added PFAS-Free.
• Freezer Restrictions: It is highly recommended not to expose this product line to blast freezing environments below −30°C.
• Certifications: Fully credentialed to EN 13432 compostability limits and Feed a Field™ ethical markers.

• 🟢 Green (Best): Covered in sandwich ingredients, crumbs, or spreads? Place the used bag directly into your home compost pile or commercial food waste collection bin. It completely decomposes into organic nutrients in under 6 to 16 weeks.
• 🟡 Amber (Good): If the bag remains entirely clean and dry, it can be collected with your standard household paper and cardboard dry recycling streams (notify your waste company it is wood-pulp based).
• 🔴 Red (Okay): If general facility waste is the only option, these purely botanical fibers naturally decay over time in landfill without polluting soils with persistent microplastics.
