Medical Blister Packaging - Thermoformed Blisters for Syringes, Needles & Surgical Kits
Custom-made medical blisters and blister packaging for syringes, needles, implants, surgical kits, and diagnostic devices.
What Is Medical Blister Packaging?
Medical blister packaging, also called thermoformed blisters, are rigid medical-grade plastic trays that securely hold and protect sensitive products such as syringes, needles, catheters, implants, or surgical kits. They prevent mechanical damage and contamination while ensuring that sterility is maintained until the point of use.
Why Are Thermoformed Blisters Ideal for Medical Technology?
Thermoformed blisters are precisely tailored to the shape and geometry of the medical product. The result: custom-fit medical blister packaging that meets the highest standards for product protection, sterility, and process integration.
- Complex or sensitive products: secure packaging for catheters, sensors, or surgical instruments
- Sterile environment requirements: cleanroom-manufactured sterile packaging for surgical kits, implants, and diagnostic sets
- Automated packaging and filling in production lines
- Traceability & regulatory compliance: blister packs for MedTech that meet MDR, UDI, ISO 11607 requirements
- Cost-efficient production for small to medium series: ideal for new product development, special batches, or customized components
- “Tray ready for use”: product trays designed for automation, robotics, or line integration
- Logistics & storage optimization: through stackable medical trays and reduced material use
Functions & Features of Medical Blister Packaging
Product Protection & Sterility
Medical blisters protect sensitive components against mechanical stress, moisture, and contamination. Depending on the material, they are suitable for gamma, ETO, or steam sterilization.
Custom-Fit Fixation
Thermoformed blisters are adapted to product geometry. Nesting cavities prevent movement, allow automated line handling, and ensure secure logistics.
Transparency & Visual Inspection
Transparent blister materials allow visual checks of products, barcodes, or batch data – critical for quality assurance and clinical workflows.
Smart Medical Blister Concept With the 3D Tray Generator
Do you have a medical product – for example, syringes or diagnostic kits – and want to see how a custom-fit blister might look?
With formary’s 3D Tray Generator, you can upload your CAD model and automatically create a 3D design of the blister packaging. This saves development time, prevents design errors, and provides a quick visual impression of your medical blister.

Advantages of Medical Blisters Made of Plastic
Lightweight
Thermoformed medical blisters are lightweight and space-saving in design. They can be stacked, automatically removed, and efficiently integrated into surgical sets or kit logistics.
Material Variety
Thermoformed packaging for medical technology offers a wide selection of certified mono-materials (e.g. PET-G, PP) with recyclability and potential for bio-based solutions.
Fast Development
Thermoforming tools are more cost-efficient and available faster than injection molds. This makes thermoformed blister packaging ideal for R&D and small series.
Cleanroom & MDR Compliance
Thermoformed blisters for medical products can be manufactured under cleanroom conditions, compliant with EU MDR & UDI requirements.
Product Safety
Medical blister packaging provides protection against shocks, moisture, and contamination. They are compatible with sterilization methods such as gamma, ETO, or steam.
Automation Compatibility
Blister packaging for medical technology is ideal for automated filling, sealing, and palletizing. It allows seamless integration into existing production processes.
Suitable Materials for Medical Blister Packaging
Applications of Medical Blister Packaging
Blister Packaging for Syringes & Needles
Medical blisters reliably fix and protect sensitive products such as syringes, needles, catheters, or adapters during transport and storage. Depending on requirements, single- or multi-chamber blisters, combination blisters, or inlays for syringe sets are possible – sterile or non-sterile, ISO 11607 validated.
- Typical applications: disposable syringes, insulin syringes, dental anesthesia syringes, prefilled syringe cartridges, needle sets, vaccine and filler sets
Materials: transparent medical-grade PVC, clear medical-grade PET-G
Properties: transparent, dimensionally stable, stackable, precise cavities, protection against rolling, scratches, and damage, excellent visual inspection, compatible with secondary packaging (e.g. folding cartons)
Sterile Packaging for Surgical Instruments & Kits
For surgical instruments, kits, and sterile goods, we develop sterile packaging (sterile barriers) with Tyvek® lids or film sealing. These ensure maximum safety of medical products until opened in the operating room.
- Typical applications: bipolar forceps, clamps, electrodes, disposable instruments, reusable instrument trays, complete surgical kits
Materials: medical-grade PS (ESD blue or black), medical-grade PP (white, transparent)
Properties: robust design with 1–1.5 mm material thickness, optional ESD protection, stackable, rounded radii for safe handling, sealing edge for sterile packaging
Packaging Trays for Diagnostics & Test Kits
Thermoformed blisters are ideal for diagnostic and lab kits, such as COVID tests or blood analysis kits. Different chambers secure components like test tubes, pipettes, or rapid tests while allowing simple visual inspection.
- Typical applications: COVID tests, blood analysis kits, lab diagnostics, ophthalmology applications (lens holders, intraocular lenses), rapid tests
Materials: PET-G, A-PET transparent, medical-grade PS
Properties: dimensionally stable, stackable, clear visibility, precise cavities for pipettes, tubes, or lens holders, protection against twisting and scratching
Dental & Sample Packaging
In the dental field and for the safe transport of medical samples, resealable blisters and clamshell packaging are used.
- Typical applications: dental sets (anesthetic cartridges, filling materials, needles), sample and transport packaging, cartridge carriers for diagnostic or lab applications
Materials: PET-G, A-PET transparent
Properties: resealable (e.g. hinge design), clear transparency for visual checks, hygienic storage, reliable protection against moisture and dirt
Service & Maintenance Blisters
Medical blisters are also used for spare parts and maintenance kits, ensuring organization, protection, and transport of small components.
- Typical applications: maintenance kits for dialysis devices, pump systems, or MedTech modules
Materials: combinations of A-PET transparent, black PS, or other medical-grade materials
Properties: stackable, space-saving, reliable protection of small parts against loss and damage
Sustainable Alternatives: Molded Pulp
In addition to traditional plastic blisters, molded pulp packaging is becoming increasingly important as a sustainable alternative for certain diagnostic or test kits.
- Typical applications: inserts for COVID or rapid test kits, lab samples, consumer goods packaging
Material: molded pulp (cellulose, starch, water)
Properties: shock-absorbing, stable, hygienic, biodegradable, compostable
