PLASTIC Food Packaging
PLASTIC food packaging PROPERTIES AND APPLICATIONS Plastic is light-weight, versatile, and inexpen- Since the 1950s, plastic has found countless Plastic is often used in combination with other sive. Most types of plastics are made with applications in food packaging items, such as materials such as paper & board, metals, fossil carbon, but renewable carbon sources bottles, trays, bags, and films. glass, printing inks, adhesives, and coatings. are increasingly used as raw material. COMPOSITION OF PLASTIC CHEMICAL SAFETY PACKAGING Plastics can transfer chemicals into packaged Plastics consist of polymers forming the food or beverages. This process is called structure of the material, and various additives chemical migration. In most cases, some of further customize the technical properties. A the migrating chemicals are known, while large variety of different chemicals can be used many others are identified only partially or not to produce plastic food packaging. Many of at all. Chemical migration depends on factors them have hazardous properties, and others such as food type, temperature, and storage lack publicly available toxicity data. In addition, time.
