The blister manufacturer: Frequent Problems and Instant solutions while coding

Blister packaging is a common term, especially in terms of packaging items in the bakery sector, electronic items, and also in the food grade industry. But during packing, a blister manufacturer needs to do proper printing and labelling of the packaging before a product is shipped.





It's critical for products to have the correct coding information to comply with applicable governing bodies' regulations. However, producers may face issues when coding into blister packaging. However, a manufacturer faces several problems that happen during the printing and labelling of cases. And there are various solutions. Let’s discuss in detail:

Common problems
  1. Quality of code - According to the size and substrate on which they are printed, all codes must be mechanically readable. Because foil is commonly used in blister packaging, the innovation must be capable of printing at a high resolution to meet industry standards. Quality control checks will fail if the codes are not crisp, clean, or clear, resulting in substantial downtime, and a hike in ink usage and also contributing a lot to incessant product wastage.
  2. Line of production speed: The volume of throughput is large in the pharmaceutical, electrical, and toy industries. Manufacturers may face difficulties maintaining precision, efficiency, quality control, and minimizing downtime if they do not have access to a dependable solution. Manual tasks can also take a long time when transitioning to a new product and, as a result, different coding messaging.
  3. Types of packaging materials: Blister packing is used for a variety of purposes, some of which necessitate the use of specific packaging materials like foil or Tyvek®. Makers will have to choose a suitable ink that is suited for quick adherence based on the material. Fast-drying periods are required for products that interact with other materials and should not smear after printing.
  4. Product handling: Products must be provided to the printhead in a consistent and regulated format so that the coding to be applied to the appropriate locations at a fixed time.
Implemented solutions

There is a variety of techniques accessible for manufacturers based on the difficulty level of the code which is been applied to the blister packaging, as well as the substrate material itself. The following are the three options:
  1. Laser: It can generate numerous lines of text and provide flexible, high-speed, high-quality coding on a wide range of materials. It can provide both human-readable and 2D DataMatrix code, as well as solutions that meet serialisation rules and other traceability requirements legally. They don't need inks or solvents, which saves time and money, and their IP65 certifications make them appropriate for even the roughest conditions.
  2. The thermal transfer overprinting: By controlling the ribbon tension, it results in clear, crisp coding, increasing production speed and almost reducing downtime. It has a low total cost of ownership since it fits into almost all current thermal transfer brackets, which reduces installation expenses all at once. 
  3.  The Thermal inkjet: It has quick-dry periods and strong adhesion, making it ideal for fast-paced production lines.
