High-performance packaging will help to keep food fresh for extended periods. Polymer packaging also has low moisture/vapor transmission rates to keep food and consumers safe. It also helps to keep meat fresher longer, because plastic films for fresh meat packaging are specifically designed to allow a small amount of oxygen to pass through the film, thus maintaining the oxymyoglobin that gives meat its fresh red color.2
Fresh Vegetables and Fruits
Plastic packaging has been known to extend the shelf life of perishable foods such as fresh fruits, vegetables, and meats, which helps to reduce food waste. One way this is achieved is through modified atmosphere packaging, which helps the container provide a reduced-oxygen air mixture that better preserves food.3 1 The moisture- and chemical-resistant properties of HDPE and LLDPE keep produce fresh and prevent wilting.
HDPE is an approved food-safe material4 that is typically used to make cereal and snack liners. HDPE is strong enough to stand on its own, making it ideal for cardboard box liners. It also offers moisture-resistant properties to protect from liquids and helps dry goods last longer.
Refrigerated and Frozen foods
Milk, juices, cheese, and other cold-storage items are typically packaged in rigid or flexible plastic. HDPE is impact resistant to protect liquid packaging from punctures. Plus, both forms of PE can withstand a wide range of temperatures, covering the products from the outside environment.5
