Definitions

• Packaging serves essential functions in the transportation, safeguarding, presentation, and exhibition of goods. This industry finds applications across a spectrum of sectors, including fast-moving consumer goods, medical and healthcare, and hospitality.
• packaging plays a critical role in preserving product integrity, application suitability, and shelf life.
• packaging serves as a vital shield against damage, contamination, external environmental factors, and harmful microorganisms.
• Blister packs consist of pre-formed packaging materials, typically featuring a thermoformed plastic cavity and a flexible, bendable lid. Within this type of packaging, the product is securely placed into deep-drawn pockets or cavities that resemble raised blisters. Blister packs are most employed for the packaging of pharmaceutical products, such as pills, tablets, capsules, and lozenges. Their popularity arises from their ability to protect and present medications effectively.

• thermoforming sheet is initially fed through a thermoformer plate, which is heated to a controlled temperature, typically within the range of 110 to 140°C, with a specific preference for temperatures falling between 120 and 127 °C. Tablets are then loaded into the thermoformed grooves on the heated sheet using a tablet feeder. Subsequently, a sealing material is applied to the tablet-filled thermoformed sheet at a designated sealing temperature, typically ranging from 110 to 125°C, with a more precise preference for temperatures between 113 and 120°C. Finally, the sheet with the sealed tablets undergoes cutting at a series of aligned cutting stations, resulting in the individual tablets being securely sealed through this comprehensive process.
