Environmental Footprint of Metal vs Plastic Packaging
Most people think they are making a sustainable choice when opting for metal packaging, as metal is thought to be durable and recyclable. Unfortunately, this is not always the case.
Metal packaging, just because it's recyclable, doesn't necessarily mean it's the most sustainable packaging option. There are several indirect impacts such as transportation of heavy metal packaging and energy consumption during the manufacturing of metal that severely burden its life cycle. Plus, a great deal of used metal still goes to landfills due to the way metal is disposed of by consumers.
Here are some things to consider regarding the environmental footprint of metal:
Sustainability Drawbacks of Metal
Resource-intensive, greenhouse gas (GHG) emission heavy manufacturing process
Heavy packaging material, making it less environmentally friendly in transportation
Incinerating non-recycled metal causes a lot of CO2 emissions
Depending on the industry and products your business carries, choosing metal packaging can have disadvantages beyond sustainability. Below are some factors to take into account:
Other Disadvantages of Metal
Expensive packaging material due to the weight
Vulnerable to corrosion, such as rust
Rigid and difficult to store effectively
Dents easily, making the packaging vulnerable to leakage
Packaging is only available in a few shapes and sizes
Problematic supply chain and instable pricing
Metal is known for its durability but is generally not the best packaging choice. Although plastics are the subject of frequent global debate and criticism, they play an important role in reducing greenhouse gas emissions compared to alternatives such as metal and glass. Over the past 15 years, many manufacturers have switched to plastic packaging for reasons such as sustainability, design versatility, supply chain flexibility and durability.
By replacing your metal packaging with plastic, you can avoid corrosion, support the circular economy, and lower costs without compromising design freedom.
Advantages of Plastic
Less intensive to produce, reducing greenhouse gas (GHG) emissions
Weight efficient, thus lower cost and easier to transport
Durable with a long life cycle
Stable supply chain and pricing
High density polyethylene (HDPE) and polypropylene (PP) are widely used for packaging, but don't provide effective barriers against many ingredients. This can result in discoloration, weight loss, labels coming off, loose caps, ingredient loss and formulation instability. Choosing Enkase barrier technology will enable protection, full recyclability and allow total design freedom for your packaging.
