For example, cartons are widely used to protect food items due to their durability, preventing contents from being crushed. This is especially important for delicate products like eggs, which require sturdy packaging to avoid breakage.
Beyond physical protection, packaging also safeguards food from environmental threats like moisture and oxygen. Moisture can lead to mold and bacteria growth, while oxygen can cause oxidation, resulting in rancidity and nutrient loss. To address these issues, packaging often includes barrier overwraps, sealed pouches, or liners to block moisture and oxygen, helping to extend the shelf life and preserve the quality of food.
Vacuum-sealed packaging, for instance, is commonly used for perishables like meat and cheese. By removing air, it reduces oxygen exposure, slowing oxidation and spoilage. Similarly, moisture-resistant materials like polyethylene provide a barrier against water vapor, keeping food dry and fresh.
Advanced techniques like modified atmosphere packaging (MAP) are also used to improve food preservation. MAP changes the gas composition inside the packaging, slowing microorganism growth and prolonging shelf life, particularly for fresh produce, meats, and bakery products.
In conclusion, packaging is essential for protecting food from mechanical and environmental risks throughout supply and distribution. Through physical barriers and innovative technologies, it ensures food remains safe, fresh, and high-quality until it reaches consumers.
