Food Packaging Types
Glass – Because it is moisture and heat resistant, glass is an excellent choice for foods with a lengthy shelf life. This permits you to heat treat the product after it’s been filled and it won’t let any air in as long as the seal is secure. Glass is non-reactive with food and can be made translucent to allow viewing of the contents of the package. Glass can also be tinted to prevent light from damaging the product’s quality, as in a brown beer bottle.
Metal-Stainless steel, aluminium, and tinplate are the most common metals used in packaging. Because of the features of food-safe metal, the packaging is heat resistant, long-lasting, and easily recyclable. Metal cans containing acidic foods may corrode, producing changes in the food’s quality, loss of barrier integrity, and, as a result, a reduction in shelf life.
Paper and Cardboard — Compared to metal and glass, paper and cardboard packaging is lightweight and inexpensive. It’s also a substance that’s easily recyclable and compostable. When paper-based packaging comes into contact with moisture or humidity, the barrier integrity is disrupted, making it easier to rip or damage.
Food Grade Plastic – One of the greatest materials for food safety and product quality is food grade plastic packaging. Plastic has good barrier properties, which means that once wrapped, it protects the food from any pollutants. The barrier features of packaging have an impact on a product’s shelf life and prevent it from spoiling or deteriorating in quality, resulting in less food waste going to landfill. Some food-grade plastics can be recycled as well.
