In life, we can often see some products are packaged by packaging companies, such blister materials are mainly used for packaging products, such as toys, hardware, food and medicine. Many blister packaging machines use heat and pressure to form a cavity or pocket from a roll or plastic sheet through a mold. In recent years, improvements in cold forming, especially allowing steeper depth angles during the forming process, thus minimizing the amount of material per cavity, have helped to improve this technique. The main advantage of plastic-type blister packaging is its more compact size compared to cold-formed aluminum and its transparency seen in the product. Blister packaging has many applications in medicine and medical equipment, the most common is the unit dose packaging used in tablets, capsules or lozenges. Blister packaging can provide barrier protection for shelf life requirements and provide a degree of tamper resistance. In some countries, blister packaging is mainly used to package doctor samples of drugs or over-the-counter products (OTC) in pharmacies. Blister packaging is the main type of packaging in some other countries, because pharmacy dispensing and repackaging are not common. PET blister tablets have the advantages of non-toxic, reliable health performance, and Y-ray disinfection of its packaged items, so combined with the above characteristics of PET blister tablets and the rational use of PET blister packaging, which brings great uses to the packaging of products in life.
