Case for Mono-Material Packaging
What is Mono-Material Packaging?
Mono-material packaging refers to packaging made entirely from a single type of plastic, such as polyethylene (PE) or polypropylene (PP), which help to simplify recycling processes. A stand-up pouch made entirely of polyethylene is easier to recycle compared to a typical chip bag, which uses mixed materials (Image below)
Mono-Material Plastic Packaging Matters
With the evolution of blown film lines, both multi-material and mono-material packaging concepts have evolved exponentially within the flexible packaging industry.
As the conversation around sustainability intensifies, the demand to shift from multi-material flexible plastic packaging to mono-material structures is growing rapidly.
While new materials like biodegradable or compostable options promise sustainability, they face challenges such as cost, performance, and availability. Here’s why mono-material packaging is a practical alternative:
Compatibility with Existing Systems. Transitioning to mono-material films doesn’t require replacing your entire filling and packing system—just fine-tuning parameters to achieve the perfect settings.
Recycling-Friendly Mono-materials work seamlessly with current recycling systems using advanced technologies like Near-Infrared (NIR) spectroscopy. These systems easily detect and sort mono-materials, improving sorting efficiency and recycling rates.
Versatility Widely used in food packaging for dry and frozen goods, mono-materials are ideal for applications like stand-up pouches, block-bottom bags, and MAP systems.
Functionality, mono-material doesn’t mean mono-layer. Advanced designs deliver the required barrier properties, appearance, and user-friendly features like resealable zippers.
Choosing the Right Solution
When designing sustainable packaging, it’s crucial to consider your specific needs and requirements, there's no one-size-fits-all solution. In generall, the best decision balances sustainability goals with practical needs and production realities.
