Your Guide to Sustainable Packaging Materials
Understand the different types of sustainable packaging, when to use each, and how to choose the right solution for your products.
Types of Sustainable Packaging
Each sustainable packaging type has unique properties, benefits, and ideal use cases
Paper & Cardboard
Materials: FSC-certified kraft paper, corrugated cardboard, molded pulp
Best for: Shipping boxes, food containers, retail bags, protective packaging
Sustainability Benefits
- Renewable resource (sustainably managed forests)
- Widely recyclable in existing infrastructure
- Biodegradable if uncoated
- Lower carbon footprint vs plastic
Considerations
- Moisture sensitivity (requires coating for wet products)
- Lower strength-to-weight ratio than plastic
- Some coatings can reduce recyclability
Common Certifications: FSC, PEFC
Compostable Bioplastics
Materials: PLA (Polylactic Acid), PHA, starch-based polymers, cellulose films
Best for: Food service packaging, produce bags, coffee capsules, flexible films
Sustainability Benefits
- Made from renewable resources (corn starch, sugarcane)
- Compostable in industrial facilities (EN 13432)
- Reduces dependency on fossil fuels
- Lower carbon emissions during production
Considerations
- Requires industrial composting (not home compostable)
- Limited recycling infrastructure
- Performance varies by temperature and humidity
- Higher cost than conventional plastic
Common Certifications: EN 13432, OK Compost, Seedling
Recycled Materials
Materials: rPET, recycled cardboard, recycled paper, recycled glass
Best for: Bottles, containers, shipping boxes, protective packaging
Sustainability Benefits
- Reduces virgin material extraction
- Lower energy consumption vs virgin materials
- Keeps waste out of landfills
- Established collection systems
Considerations
- Quality degrades with multiple recycling cycles
- Food contact requires virgin or food-grade recycled material
- Contamination affects recyclability
- Availability varies by region
Common Certifications: Recycled Content Certification, ISCC PLUS
Reusable Systems
Materials: Durable plastics, glass, metal, wood
Best for: Return logistics, premium products, bulk distribution, B2B shipping
Sustainability Benefits
- Lowest impact per use (with sufficient reuse cycles)
- Eliminates single-use waste
- Premium brand perception
- Long-term cost savings
Considerations
- Requires reverse logistics system
- Higher upfront investment
- Cleaning and sanitization needed
- Not suitable for all products/markets
Common Certifications: ISO 14001 (environmental management)
How to Choose the Right Packaging
Consider these factors when selecting sustainable packaging for your products
Product Type
- Food contact requires food-safe certifications (BRC, FSSC 22000)
- Dry goods: paper/cardboard works well
- Liquids/moisture: need barrier coatings or bioplastics
- Fragile items: molded pulp or recycled plastic cushioning
Shelf Life & Protection
- Long shelf life: may need oxygen/moisture barriers (coated paper, PLA)
- Frozen foods: ensure material performs at low temperatures
- UV-sensitive: opaque materials or UV-blocking films
- Mechanical protection: corrugated cardboard, molded pulp
Distribution & Logistics
- Local distribution: lighter materials reduce transport emissions
- International shipping: durability and moisture resistance critical
- Temperature control: material must withstand cold chain
- Stacking strength: corrugated cardboard with appropriate ECT rating
End-of-Life
- Home compostable: PLA with OK Compost HOME certification
- Industrial compost: EN 13432 certified materials
- Recycling stream: paper, cardboard, rPET work best
- Regional infrastructure: verify local waste management capabilities
Cost & Volume
- High volumes: economies of scale favor paper/cardboard
- Small batches: bioplastics may have higher minimums
- Budget constraints: FSC paper often most cost-effective
- Premium positioning: reusables or innovative bioplastics
