What are the Cling Wrap and Environmental Concerns? Is Cling Wrap Safe for the Environment?

Plastic food wrap, or any industrial food wrap manufactured using plastic, can be seriously environmentally concerning. The reason behind this is the plastic, containing hundreds to thousands of microplastics. Such cling films lack natural raw material; thus, they are non-biodegradable, non-recyclable, and non-compostable. They cannot be broken down by microorganisms present in the soil. Thus, once you dispose of them after using them, they remain unaffected on the land even after many years. Due to this reason, they are known for contributing to land pollution. 

The friendly nature of plastic-containing cling films is also polluting our surroundings. The only way to eliminate them is by burning them, which can cause more severe damage. Their burning eliminates harmful gasses such as carbon dioxide in the environment. Such gasses are polluting our air and contributing to increased global warming, a rising global issue of modern times. 

Besides affecting land and air, cling films also affect the water bodies and cause serious harm. Microplastic present in plastic materials not only pollutes the water but also causes damage to fish. The fishes may engulf them, considering them their foodstuff. In this way, they can result in severe health hazards or even the death of fish. 

In contrast, cling films, made using biodegradable, natural materials, are non-hazardous for land, air, and water bodies. It does not cause any pollution because of its high biodegradability, compostability, and recycling. They are broken down by microorganisms and vanish from the land or water whenever you throw them away. Even their burning does not pollute the air because of the lack of harmful gasses. Additionally, eco-friendly cling films do not cause chemical leaching; thus, they are the best food wrapping, covering, and packaging options. 

How to Properly Dispose of Cling Films or Wrap?

As we know, cling films containing plastic material cannot be recycled. Thus, you cannot dispose of them openly because they can harm our environment. They can cause pollution if not handled properly. Thus, the only good way to dispose of them is by putting them into dustbins. So, whenever you need to throw away the cling wrap, a careful way of disposable should be used. You can carefully put it in a trash bag box or a container instead of openly throwing it on land.
