Medical Blister: Features of an Excellent Product

The term “blister” refers to a pre-formed plastic packaging used to contain small items. The hallmarks of an excellent product, widely used in the medical field, are definitely its lightness, ease of handling, and ability to protect its contents.

Today, the medical sector mainly uses blisters for operating rooms.

Technical Features of the Medical Blister

Blisters consist of two components:

  • Cavity: This is a part made of deformable material such as plastic and aluminum, obtained by heating the blister using mechanical tools like thermoforming machines.
  • Lid: Which can be made of paper or plastic and carries information about the manufacturer and contents.

Medical Blister: Its Importance in the Operating Room

In the field of medicine, blisters are used for packaging pharmaceutical products like pills and other medicines. However, the primary use of medical blisters is in the operating room, where doctors need sterile, single-use instruments.

Among the advantages of using blisters in the operating room are the utmost hygiene they offer, along with the guarantee of always having an intact product, and the simplicity and ease of opening the packaging when needed.

The blister is widely used in the operating room for various reasons and offers many benefits. Here are some of the main advantages of using blisters in the operating room:

  1. Sterility: Blisters are designed to maintain the sterility of surgical instruments and materials, post-irradiation or ETO gas, during storage, transportation, and handling. They are made of durable materials that prevent the entry of bacteria, microorganisms, and other contaminants into the sterile environment.
  2. Protection from shocks and damages: The blister provides a protective barrier that reduces the risk of instruments getting damaged during handling and transportation. Delicate surgical instruments can be securely placed inside the blister, avoiding direct contact with other surfaces or objects that could cause damage.
  3. Easy identification: The blister is often transparent or has a transparent window, allowing for easy identification of the instruments and materials inside without having to open the packaging. This enables healthcare professionals to quickly locate the necessary instruments for surgical procedures, reducing preparation times.
  4. Contamination control: Blisters offer an effective barrier against contamination during transportation and storage. Surgical instruments are securely packaged inside the blister, minimizing the risk of contamination from dust, particles, or external substances.
  5. Ease of opening: Blisters are designed for quick and easy opening, allowing medical staff to access the instruments efficiently without complex procedures. This helps reduce preparation time before surgery.
  6. Traceability: Many blisters come with labels or barcodes that make it easy to trace surgical instruments, production batches, and other pertinent information. This can be useful for inventory management, quality control, and product recall tracking if necessary.

The most common material used for producing medical device blisters is PETg, and in other cases, PVC or PET.

How Blister Production Takes Place

Niada NBC produces blisters for the medical sector at high temperatures. The plastic film wrapped around a spool is unrolled and processed in a “pre-heating station” where it is brought to a temperature, varying based on the material used, where the plastic becomes malleable. The warm plastic is then moved to a second station where, using a high-pressure mold (between 4 and 8 bar), the various cavities are imprinted. After this process, the plastic is cooled and the mold removed, ensuring the shape remains imprinted on the film.
