Product Description

Please note these bags are being replaced with our new bags, so they are reduced to clear.

Section Product Details
Short Description The definitive premium, plastic-free showcase for luxury tea emporiums, specialty coffee roasters, and artisan bakeries. Our Premium Compostable Kraft Heat-Seal Bags feature a crystal-clear, anti-fog NatureFlex™ viewing window made entirely from renewable wood pulp cellulose. Crafted from heavyweight, unbleached kraft paper, these structural stand-up pouches are designed to work perfectly with impulse heat sealers to lock in volatile aromatic oils, maintain crisp textures, and present your premium blends with zero petroleum footprint.
Product Overview

Preserve Delicate Aromas & Volatile Oils: For high-end coffee roasters and tea merchants, oxygen and moisture migration are the enemies of flavor. While standard paper bags allow essential oils to dissipate and leave unsightly grease stains, our premium pouches feature a high-barrier NatureFlex™ inner lining. This botanical matrix traps delicate aromas, delicate herbal bouquets, and rich coffee notes inside, ensuring your customers experience the exact flavor profile you intended while preventing external ambient humidity from spoiling the contents.

Artisan Aesthetics with Flawless Window Clarity: Elevate your retail shelves with the tactile charm of heavy-duty brown kraft paper paired with a high-gloss, static-free viewing window. Unlike oil-based plastics that attract dust and cause internal condensation to fog up the display, our wood-pulp window strips remain perfectly clear. Your loose-leaf tea blends, colorful botanicals, freshly roasted single-origin beans, or glazed artisanal pastries are showcased beautifully with full-length transparency.

Professional Heat Sealing for Tamper-Evident Freshness: Tailored specifically to integrate smoothly into busy packing passes and commercial processing lines. The specialized plant-based barrier lining is optimized to melt smoothly under low-temperature impulse heat sealers. This creates an airtight, robust, and tamper-evident security weld that preserves optimal product freshness from the moment it leaves your scales to the second it is opened at home.

Key Features & Benefits
  • NatureFlex™ Window: High-clarity viewing panel made from certified compostable wood cellulose—absolutely zero crude oil or petrochemicals.
  • Heavyweight Unbleached Kraft Paper: Premium, thick structural paper body that offers visual rustic charm and total grease-proof resistance.
  • Aroma-Lock Oxygen Barrier: Exceptional protection matrix preserves delicate loose tea scents and volatile coffee bean roasting oils.
  • Low-Temp Heat Sealable: Optimized to fuse smoothly under standard impulse sealing bars to guarantee tamper-evident retail freshness.
  • 100% Certified Compostable: Fully accredited to strict Feed a Field™ and EN 13432 protocols for plastic-free disposal.

Storage Guide

Because our premium kraft bags rely on natural wood pulp cellulose elements, basic storage care ensures long-term operational performance:

  • Keep It Dry: Always protect the unbleached kraft paper fibers from heavy sink steam, damp roasting room environments, or wet floors.
  • Stable Temperatures: Store within a climate-managed room away from immediate proximity to commercial coffee roasters, baking ovens, or radiator pipes when inactive.
  • Out of Direct Sunlight: Keep 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 delivery date to ensure optimal heat-seal properties.
Technical Specifications
  • 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.
  • Sealing Profile: High-performance, low-temperature impulse and rotary thermal weldable.
  • Certifications: Fully credentialed to EN 13432 compostability limits and Feed a Field™ ethical markers.
Disposal Guide
  • 🟢 Green (Best): Covered in coffee oils, fine tea dust, or pastry crumbs? 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.
  • 🔴 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.
