Choosing the Right Layers: A Balancing Act for Product Protection
Selecting the ideal combination of plastic layers isn't a one-size-fits-all approach. It's about understanding the unique needs of your product and tailoring the packaging accordingly. Here's how WVTR and OTR influence your choices, along with other crucial factors:
1. Understanding Product Sensitivity:
- High Sensitivity: Products like pharmaceuticals and electronics necessitate materials with exceptionally low WVTR and OTR, such as aluminum foil, EVOH (ethylene vinyl alcohol), or high-barrier plastics like PVdC (polyvinylidene chloride). Multiple layers might be required for maximum protection.
- Moderate Sensitivity: Items such as snacks and baked goods demand a balance between barrier effectiveness and cost-efficiency. BOPP and BOPET are suitable for moisture protection, while incorporating a layer of aluminum foil or metallized film enhances oxygen barriers.
- Low Sensitivity: For products like fresh produce and certain personal care items, LDPE and CPP are adequate for basic protection, though additional layers might be beneficial for prolonging shelf life or meeting specific barrier needs.
2. Shelf Life Expectations:
- Long Shelf Life: Select materials with very low WVTR and OTR to preserve product quality over extended periods.
- Short Shelf Life: Flexibility in material choice is possible, but considerations such as moisture absorption and aroma preservation remain crucial.
3. Packaging Format and Functionality:
- Pouches: Typically require flexible materials like LDPE or CPP, known for their sealing capabilities and puncture resistance.
- Rigid Containers: Use BOPP and BOPET for their rigidity and printability, enhancing the overall packaging structure.
- Additional Features: Consider factors like ease of opening, resealability, and enhancing the consumer experience through practical design.
4. Advance Sustainability Goals:
- Recyclability: Favor mono-material or same polymer family structures that facilitate easier recycling.
- Bio-Based or Compostable Options: If these align with your environmental objectives, they can be viable choices.
