Medical Support Inserts / Backing Cards — The Invisible Armor Inside Packaging
Every shift of a device during transit threatens the integrity of the sterile barrier. Though medical support inserts and backing cards do not form the sterile barrier themselves, they act as invisible armor to restrain movement, avoid collision and prevent sharp components from puncturing packaging. Martin provides die‑cut inserts made from HDPE and PP.
Overview
Medical support inserts and backing cards sit inside blister trays or sterile pouches to fix devices, limit displacement and protect sharp tips. Martin offers custom die‑cut HDPE and PP inserts, with early DFM review together with blister tray development.
Materials & Applications
- HDPE Inserts Flexible, high impact resistance and precise die cutting. Ideal for trocars, surgical blades, hypodermic needles and other sharp devices requiring tip protection.
- PP Inserts Higher rigidity, excellent heat resistance and good flex fatigue performance. Suitable for orthopedic drills, metallic implants and large devices demanding strong support.
- Functional Styles Tip sleeves (cover sharp points to avoid lid puncture), tray inserts (full device restraint), and contoured locating pockets to constrain movement inside cavities.
Martin’s Advantages
- Early DFM Collaboration Support insert requirements are evaluated during blister cavity design, preventing poor fit and extra cost caused by late modification.
- Cleanroom Fabrication Die cutting in controlled clean environment with smooth, burr‑free edges to reduce particulate contamination risk.
- Compliant Medical Grade Materials Medical‑grade HDPE and PP raw materials, meeting biocompatibility and cleanliness requirements, compliant with ISO 11607.
