Product Design Brief – Absorbent Liner Bin Bag

Project Overview

We are developing an innovative bin bag with a liquid-absorbing liner, designed to trap and contain moisture, reducing leaks, spills, and odours. This product will differentiate itself from standard bin bags by offering a built-in absorbent layer, making it ideal for households, commercial kitchens, healthcare, and industrial applications where liquid waste is common.

Key Design Requirements
1. Material & Durability
• Multi-layer construction:
• Outer Layer – Tear-resistant, leakproof plastic (biodegradable or recycled options available).
• Inner Liner – Absorbent material capable of soaking up liquids, grease, and spills.
• Sealed base – Reinforced to prevent leakage and sagging.
• Designed for high-capacity and heavy-duty use.
2. Absorbent Liner Technology
• Liner made from super-absorbent polymer (SAP) material or plant-based absorbent fibres.
• Capable of absorbing up to X millilitres per bag (to be determined based on testing).
• Prevents odour buildup by locking in moisture and reducing bacterial growth.
3. Closure & Sealing Mechanism
• Drawstring closure for easy tying and transport.
• Alternative options: tie-handle or self-sealing flap for secure containment.
• Potential for odour-neutralising technology integrated into the closure area.
4. Size & Capacity Variations
• Standard (20–30L) – Ideal for home use.
• Large (50–80L) – Suitable for commercial and industrial settings.
• Extra-Large (100L+) – Heavy-duty waste collection applications.
5. Sustainability Considerations
• Available in biodegradable, compostable, or recycled plastic variants.
• Option for eco-friendly packaging, using minimal plastic wrapping or bulk-roll designs.
6. User Convenience & Features
• Pre-folded dispensing for easy access from a roll or box.
• Odour and spill containment to improve hygiene and reduce cleaning effort.
• Suitable for wet waste, food waste, and general refuse without compromising strength.

Design Deliverables Required:
• Concept Sketches & 3D Renderings showcasing structure, liner placement, and sealing methods.
• Technical Drawings & Material Specifications for prototyping and manufacturing.
• Prototype Development Recommendations, including absorbency capacity testing and material sourcing.
