A tablet blister packing machine is a critical piece of equipment in both the pharmaceutical and nutraceutical industries, as these machines are meant for packing tablets and capsules into blister packs with efficiency. It protects the products from moisture, light, and other forms of contamination, keeping the quality and shelf life intact. The entire mechanism is done in steps: automatic, accurate, and advanced.
The process starts with the forming station, where a plastic or aluminum film is heated and molded into blister cavities. This step involves either thermoforming or cold forming, depending on the material and product requirements. Thermoforming entails heating a PVC or PET film to temperatures between 100°C and 150°C, thus making it pliable for shaping. In cold forming, aluminum foil is pressed into the desired shape without heat and offers superior protection against light and oxygen.
At this stage, the feeding station guarantees that each cavity gets the right number of tablets or capsules. Modern machines use the latest vibratory or rotary feeders fitted with sensors to detect and correct any misplacements, which could achieve a filling accuracy over 99%. For instance, the Jinlu tablet blister packing machine integrates optical sensors to minimize errors and ensure consistent filling.
The next step is the sealing station, where a lidding material, usually aluminum foil, is applied to the blister pack. The machine uses heat and pressure, typically in the range of 150°C to 200°C and up to 10 bar pressure, to securely seal the blisters. This ensures that the tablets remain protected from external factors like humidity and contamination.
After sealing, the coding and perforation station prints batch numbers, expiry dates, and other important information onto the packs. A number of machines also have perforation features, which enable the blister packs to be easily separated into individual doses. High-speed models can process up to 600 blisters per minute, greatly improving production efficiency compared to manual methods.
The last stage is the cutting and ejection station, where the blister packs are cut into their final shape and ejected for packaging. Machines such as the Jinlu blister packing machine have servo motors for precise cutting to ensure uniformity between batches.
A tablet blister packing machine offers many advantages, such as speed, precision, and product protection. According to a 2022 report from the International Society for Pharmaceutical Engineering, automated blister packing machines can reduce packaging errors by up to 70% compared to semi-automated systems, improving overall operational efficiency.
