Current chip packaging exists problems. The materials of current packaging are mostly made out of a plastic oriented polypropylene. To further strengthen the material, many chips bags have a layer of thick coating inside of bags. The materials used for chip packaging is more complicated than it looks.
Chip bags are mostly unrecyclable. The shiny lining in chip bags is often aluminum or a special mixed plastic. Since recycling plants cannot separate the plastic outer layer from the aluminum inner layer, these mixed-layer of materials cannot be recycled. Because of so many layers of plastics made of different materials as mentioned, empty chip bags would take up to 20 to 1000 years to be broken down. Consequently, this would affect the ecosystem, while spreading harmful substances throughout the country, even around the world.
Therefore, customized eco-friendly chips bag is very popular and important now. The sustainability issues caused by unrecyclable plastics can be solved by switching to environmentally friendly bags, made from recyclable or post-consumer plastic, creating recyclable food service packaging and using polylactic acid, which is a natural plastic material made from 100% annually renewable corn. Also brands can customized their chips packaging bags with plant-based compostable materials, the laminated compostable layers also have high barrier protection against moisture, water, light and oxygen to keep the chips fresh. And the compostable chips bags can break brown within 90 - 180 days in special environmental conditions.
In addition to switching the packaging materials, instructions that consist of elegant graphical elements on informing consumers how to recycle the product bags is also an essential step to create a sustainable food system. By making changes on packaging materials, Doritos will be able to reduce the plastic waste, diminish underground pollution, and avoid the spread of harmful substances, while keeping potato chips crispy even after consumers open the bags.
