A blister packing line is a specialized assembly line used in the pharmaceutical and consumer goods industries. It automates the process of packaging individual items, such as tablets, capsules, or small electronics, into pre-formed plastic blisters.
The line typically includes several stages:
- Feeding: Individual items are fed into the line, often via hoppers or vibratory bowls.
- Blister Forming: Thermoplastic sheets are heated and formed into individual cavities using molds.
- Filling: The formed blisters are filled with the respective items.
- Sealing: A heat-sealable film is applied over the filled blisters and sealed to create a tamper-evident package.
- Inspection: Automated systems inspect the packages for defects like missing items, incorrect filling, or seal integrity.
- Labeling: Labels are applied to the packages containing product information.
- Collection: The finished blister packs are collected and transported for further processing or distribution.
Blister packing lines offer several advantages, including increased production speed, reduced labor costs, improved product quality and safety, and enhanced tamper-proofing.
