Medical device packaging: The constant temperature heating heat sealing machine reshapes the technological power of green packaging

Driven by global plastic restrictions and carbon neutrality goals, the packaging industry is undergoing a transformation from traditional plastics to bio-based and biodegradable materials. With its low-temperature sealing and pollution-free emission characteristics, constant-temperature heat sealing machines have become core equipment for eco-friendly packaging manufacturing, revolutionizing sectors such as medical device packaging.

Medical Device Packaging: Dual Assurance of Sterility and Traceability

Medical device packaging demands exceptional sealability and clear identification. Constant-temperature heat sealing machines enable hermetic sealing between blister cavities and medical-grade paper (e.g., Tyvek) or aluminum foil. One medical device manufacturer adopted this process, achieving a sealing strength of 20N/15mm and zero damage rates in drop tests. An even more innovative application is permanent marking technology—using customized molds to emboss QR codes onto packaging surfaces. These codes maintained a 100% recognition rate after 100 friction tests, effectively resolving traceability failures caused by traditional printing methods.

In the medical industry, packaging is not merely an "outer layer" but a critical component ensuring sterility, safety, and full traceability. Through innovative processes and material applications, Puxiong has successfully established a dual technical system of "sealing protection + intelligent traceability," setting a new benchmark for medical device packaging.

High-Strength Sealing: Welding Technology Strengthens the Sterility Barrier

The sealability of medical device packaging directly impacts product sterility. By employing constant-temperature heat sealing technology, the manufacturer achieves molecular-level welding between blister cavities and medical-grade paper/aluminum foil through precise temperature and pressure control. This process overcomes the limitations of traditional heat sealing:

• Sealing strength of 20N/15mm: Far exceeding industry standards, ensuring the packaging withstands external impacts during transportation and storage.
• Zero damage in drop tests: Simulating extreme scenarios to verify the packaging’s comprehensive protection of internal devices.
• Optimized material compatibility: Tailoring heat-sealing parameters for different materials (e.g., PVC blisters, Tyvek medical paper) to avoid over- or under-welding, balancing sealability and material integrity.

Permanent Traceability: Embossed QR Codes Solve Industry Challenges

Traditional printed labels are prone to wear, moisture, or chemical corrosion, leading to broken traceability chains. The manufacturer innovatively applies mold-embossing technology to directly imprint QR codes onto packaging surfaces, achieving "one-step formation, lifelong readability":

• 100% recognition rate after 100 friction tests: Deep embossing (0.1–0.3mm) and surface microstructure modifications enhance QR code durability, surpassing the longevity of inkjet or laser etching.
• Integrated anti-counterfeiting and traceability: QR codes can embed batch numbers, production dates, sterilization parameters, and other information, enabling instant verification via scanning to comply with regulatory requirements (e.g., FDA UDI, EU MDR).
• Cost and efficiency optimization: Embossing requires no additional consumables, reducing per-unit marking costs by 60%. Seamless integration with automated production lines boosts efficiency by 30%.
