What Type of Boxes Are Acceptable for Medical Device Packaging
“Acceptable” depends on the device risk, sterility needs, shipping environment, and regulatory/labeling requirements. Below is a practical framework and the **box types** commonly used in medical device supply chains—from sterile barrier cartons to distribution shippers—plus how Influence Packaging helps you choose, test, and document the right spec.
Device Risk & Sterility First
Right Box for Each Layer
Tested for Distribution
Compliant Labeling
Start with the Packaging “Layers”
- Primary / Sterile Barrier (if applicable): Tyvek®/film pouches, thermoformed trays with Tyvek lids, blisters. (This isn’t a “box,” but it defines the next layers.)
- Secondary / Shelf Carton: A folding carton or small corrugated mailer that protects the primary pack and carries labeling (e.g., UDI where required).
- Tertiary / Shipper: Corrugated shipping case that protects units through distribution (parcel, 3PL, cold chain, etc.).
If the device is **non-sterile**, you’ll typically use a secondary carton and a robust corrugated shipper with the right inserts.
Acceptable Box Types & When to Use Them
| Box Type | Where It Fits | Why It’s Used | Notes |
|---|---|---|---|
| Folding Carton (SBS/CRB) | Secondary (shelf) carton | Clean print for IFUs/UDI; precise fit around pouches or trays | Common caliper 0.016–0.024″; add tamper-evidence or tear-strips as needed |
| Corrugated Mailer (E-flute) | Secondary or light tertiary | Stronger than carton; good for small kits and DTC shipments | Print-friendly; fast assembly with locking tabs; add paper inserts |
| RSC Shipper (B/C-flute) | Tertiary case | Most common distribution shipper; scalable & cost-effective | Select ECT/board grade by weight & stack time; use edge/corner protection if needed |
| FOL Shipper (Full Overlap) | Tertiary (heavier items) | Extra top/bottom strength for dense or fragile equipment | Pair with molded fiber/corrugated inserts; reinforce seams/tape width |
| Double-Wall / BC | Tertiary (heavy/large devices) | Improved compression & puncture resistance | Consider pallet pattern & humidity; may need straps or corner boards |
| ESD-Safe Corrugated / Cartons | Secondary/tertiary (electronics) | Protects electro-sensitive components | Use with ESD foams/paper; maintain ESD workstation practices |
| Cold-Chain Shippers | Tertiary (temperature-controlled) | Maintains validated temperature range | Kits with PCM/insulation; documented pack-out and monitoring |
Engineering Considerations (Choose Before You Spec)
- Sterilization Method: EtO, gamma, e-beam, steam—materials must be compatible (carton inks, adhesives, and any in-box materials).
- Distribution Risk: Parcel vs. LTL vs. air; drop/impact, compression, and vibration exposure.
- Cleanliness: Carton fibers & lint control near sterile barriers; sealed pouches/trays first, then boxes.
- Labeling: Space for UDI (if required), warnings, IFU callouts; barcode placement for scan reliability.
- Inserts: Prefer engineered paper/corrugated or molded fiber; minimize loose particulates and plastics.
Validation & Testing
- Transit: Choose an appropriate ISTA protocol for your shipping profile; verify pack performance (drops, compression, vibration).
- Shelf Life: For sterile devices, ensure packaging supports claimed shelf life with documented materials and seals (handled in primary layer, but secondary/tertiary must not compromise it).
- Change Control: Lock BOM (board grade, flute, adhesive, tape) and control revisions to keep validation intact.
