Équipements de scellage d’emballages médicaux : l’étape finale pour former une barrière stérile fiable

Within a medical packaging system, premium packaging materials and well-engineered structural design lay the foundation. Nevertheless, the final sealing process represents the critical last line of defense for the sterile barrier. The integrity of the sealing interface and the consistency of seal strength directly determine whether the device remains protected against microbial ingress throughout its shelf life.

To deliver a truly one-stop packaging solution for medical devices, Martin Medical Packaging provides high-quality medical blister trays and lidding materials, alongside a full portfolio of in-house developed medical heat sealing equipment.

Sealing Equipment

Two core equipment lines precisely cover mainstream medical packaging sealing requirements.

1. Medical Blister Heat Sealers (Multiple Models)

Designed for sealing rigid blister trays such as PETG, PET, and PP with Tyvek® or coated medical dialysis paper lidding. These machines deliver precise control over temperature, pressure, and dwell time, ensuring uniform seal width and consistent seal strength across the entire sealing path. They eliminate weak seals and leak channels to meet the stringent requirements of high-cleanliness sterile barriers.

2. Medical Pouch Sealers (Multiple Models)

• Suitable for a wide range of flat roll pouches, paper-plastic pouches, and all-plastic pouches.
• Produces continuous, smooth seal lines with high peel strength. Compatible with paper-plastic pouches, Tyvek pouches, and header pouches to support stable line speed and high sealing yield.
• An external vacuum sealing option is available for devices requiring low‑oxygen or oxygen‑free packaging environments to satisfy special application demands.

Material and Equipment Synergy

• Most sealing failures arise from poor matching between material properties and machine parameters. Martin sealers support standard production runs as well as customized process development.
• Our full equipment range works seamlessly with blister trays, Tyvek paper-plastic pouches, header pouches, center-seal pouches, PE pouches, and aluminum foil pouches. For nearly any material combination, locked-in precision parameters achieve optimal molecular fusion and reduce weak seals, leak paths, and particle generation.
