Single-material packaging: From recycling dilemma to sustainability trend
In today's consumer market, "Can it be recycled?" has become an important indicator when purchasing food. Consumers are starting to pay attention to whether the packaging indicates a single material and whether it has recycling value, which has made monomaterial packaging an important trend in the food packaging industry.
Why is a single material becoming a new trend?
In the past, composite materials were difficult to recycle due to their complex structure, and recycling plants were unwilling to process them. Single-material packaging materials, which integrate the same material such as PP, PE, and PET into one piece, simplify the structure and can directly enter the recycling system, making them easier to reuse.
Easier to recycle, environmental protection is no longer just a slogan
Mixed-material packaging requires layered disassembly, which is labor-intensive and uneconomical; single-material packaging eliminates these cumbersome steps, considers recyclability from the design stage, and truly embodies the core spirit of sustainable packaging .
Simpler to manufacture, lower carbon emissions
Composite materials require multiple processing steps, hot pressing, and bonding, resulting in high energy consumption. Single-material processing involves fewer steps, naturally reducing energy consumption and carbon emissions. Many brands that have adopted this approach have not only become more environmentally friendly, but have also seen comprehensive improvements in production efficiency, inventory management, and packaging processes.
- Smoother manufacturing process
- Energy consumption decreases and carbon emissions decrease simultaneously.
- With a single source of raw materials, inventory and production management are more efficient.
Under the dual pressures of market forces and regulations, transformation has become inevitable.
With sustainability regulations and EPR systems being implemented in various countries, brands must take responsibility for their packaging. Consumers are also more willing to choose products labeled "recyclable" and "low carbon footprint." Brands that fail to transform will be naturally eliminated by the market.
Functional Challenges: Uniform Molding, Yet Strong Enough
Single-material composites are indeed inferior to single-material composites in terms of oxygen barrier properties, heat resistance, and moisture resistance. However, these problems are being gradually overcome through technologies such as thickness adjustment, surface coating, and property improvement .
This is a sustainable reform that begins with "structural simplification." Single-material packaging is not just about packaging; it's the first step for a brand towards sustainability.
