Plastic packaging has been a topic of debate for decades, with environmental concerns at the forefront. However, one significant argument in favour of plastic is its ability to keep food fresh for longer, which has several benefits, including reducing food waste and increasing access to healthy food.
Plastic packaging prolongs the shelf life of food items, reducing waste and the need for consumers to buy the same product multiple times. This is particularly beneficial for consumers in rural areas or food deserts, where grocery store commute times are longer and poverty rates may be higher. By extending the shelf life of food, plastic packaging helps consumers save money and improves food security.
Several studies have demonstrated the effectiveness of plastic packaging in keeping food fresh. For example, cucumbers wrapped in plastic can last up to 14 days longer than unwrapped cucumbers, while bananas wrapped in plastic can last 21 days longer. Vacuum-sealed plastic packaging can keep meat fresh up to ten times longer than alternative packaging options and also maintains an appealing colour, which consumers associate with freshness.
Additionally, plastic packaging reduces contamination and spoilage during manufacturing and transport. Plastic absorbs vibration and shock from sudden movements, making it safer than glass or aluminium containers, which are more prone to denting or shattering. This further reduces food waste and makes food safer for consumers.
While there are valid concerns about plastic waste and its environmental impact, it is important to consider the benefits of plastic in certain applications, such as food packaging. Plastic packaging helps to reduce food waste, increase food security, and improve accessibility to healthy food, especially in areas with limited access to fresh produce. However, it is crucial to use plastic responsibly, improve recycling methods, and explore alternative packaging options when possible to minimise the negative impact of plastic on the environment.
