    What is Polypropylene (PP) ? It is a rigid and crystalline thermoplastic used widely in everyday objects like packaging trays, household products, battery cases, medical devices, etc. Polypropylene is a polymer whose monomer is propylene (an organic hydrocarbon with the chemical formula C3H6). The chemical formula of polypropylene is (C3H6)n. This polymer is also known as polypropene and is often denoted by the abbreviation 'PP'. Generally, polypropylene is produced via a chain-growth polymerization reaction involving propylene. This polymer is known to be a thermoplastic polymer, i.e. it softens upon heating and can, therefore, be remoulded. Its popularity had exploded and widespread commercial production. Today it is one of the most commonly produced plastics in the world. What type of products can it be made into in the blister industry? Most of them are in food industry, why for this? PP material is high temperature resistant and freezable, also it is food grade type. Polypropylene is a material that is fully recyclable. Bacteria, fungi, and other microbes are vulnerable to polypropylene. Polypropylene is a non-toxic material found in nature.

    Types of Plastic Food Packaging and Safety

    Types of Plastic Food Packaging and Safety Did you know? Plastic is a surprisingly versatile material with elemental origins. Elements from the periodic table, such as carbon, hydrogen, oxygen, nitrogen and sulfur, are the building blocks for a variety of plastics used to make many of the products we use every day. Some plastics are transparent and durable for use in eyeglasses or safety goggles. Other plastics are strong and lightweight, allowing us to ship more products with less packaging. Plastics can even be bacteria-resistant for use in food packaging and life-saving medical equipment. You don't have to be a scientist to understand the many ways plastics are useful. Plastics are used in many types of food packaging and containers for a variety of reasons – they help protect foods from damage, provides food safety and extends the freshness of foods.   What are the different types of plastics used in food packaging? You may have seen the number 1 through 7 on the bottom or side of a plastic packaging container. This number is the plastic “resin identification code,” also known as the “recycling number.” This number can also provide guidance for consumers who want to recycle plastic containers. Many major types of plastic resins used in packaging (#1 through #7) are recyclable. Most frequently, community recycling programs collect plastic bottles made from PET (#1) and HDPE (#2), but many communities are expanding their programs to collect additional types of plastics. Although most communities instruct residents to recycle by the shape of an item (e.g., bottles, containers, caps, lids), some communities also refer to the resin identification code. If you have questions about which plastics are recycled in your community, see the 2015-2016 Study on Recycling Access and check with your local recycling or solid waste facility. It’s easy to search online.
