What Are the 7 Types of Packaging? A Custom Medical Packaging Buyer's Guide

Most custom medical packaging falls into seven structural types, and each one does a different job between your production line and the patient. Picking the wrong type shows up as crushed shippers, reprinted cartons, or products that absorb moisture before use. This guide covers all seven: paperboard folding cartons, corrugated boxes, rigid boxes, chipboard boxes, plastic boxes and trays, poly bags, and foil sealed bags. You'll see what each type protects, which standards apply, and how to spec it before your next reorder.

Sort Custom Medical Packaging by Layer

Each of the seven types sits in one of three layers: primary packaging touches the product, secondary packaging holds and labels it, and tertiary packaging ships it. The layer decides which rules apply.

Part 1 of ISO 11607 defines a packaging system as the sterile barrier system plus the protective packaging around it and requires performance testing of that whole system, so your carton and shipper get tested alongside the pouch. Assign every component of your custom medical packaging to a layer before you request quotes, since a foil pouch, a folding carton, and a corrugated shipper each carry different medical packaging requirements.

Spec Paperboard Cartons for Custom Medical Packaging

Paperboard folding cartons carry most retail and pharmacy products because they print sharply, ship flat, and hold regulatory copy on every panel. Solid bleached sulfate (SBS) board in the 16 to 24 pt range covers most pharmaceutical folding cartons, with heavier calipers for glass vials and multipacks.

OTC drug cartons also fall under 21 CFR 211.132, which requires tamper evident packaging, so glue seals or perforated tear strips belong in the dieline from the start. Brands scaling a supplement line face the same caliper and tamper decisions, covered in our guide to nutraceutical packaging choices.

Put caliper, coating, and tamper feature on one drawing when you brief custom medical packaging, and ask for a plain white structural sample before any ink goes down.

Rate Corrugated Shippers Before They Leave Your Dock

Corrugated boxes protect medical device packaging through parcel networks, pallet loads, and warehouse stacking that would crush a folding carton. The fluted medium between two liners absorbs impact and resists stacking pressure, a structural difference covered in our breakdown of paperboard versus cardboard.

A standard 32 ECT single wall box carries a rating of 40 pounds and 75 united inches, and anything heavier or larger needs a higher ECT rating or double wall board. Test the full shipper to ISTA 3A for parcel delivery or ASTM D4169 for distribution simulation, since sterile device files under ISO 11607 typically cite one of those methods.

Record the ECT rating on your spec sheet so every reorder matches the box that passed testing.

Use Rigid Boxes for Kits, Chipboard for Samples

Rigid boxes suit surgical instrument sets, sales rep demo kits, and any custom packaging for medical devices that gets opened and closed repeatedly. Manufacturers build them from chipboard roughly 1.5 to 3 mm thick wrapped in printed paper, and they ship assembled, so they take up more freight and warehouse space than folding styles.

Lighter chipboard boxes use recycled grades such as clay coated news back (CCNB), which keeps unit cost and shipping weight down for sample kits and backer cards. Reserve rigid construction for products a clinician or rep will handle dozens of times, and put single use samples in chipboard.

Pair Plastic Trays With a Validated Sterile Barrier

Plastic boxes, clamshells, and thermoformed trays hold instruments and implants in fixed positions so parts can't scratch or rattle loose in transit. PETG trays sealed with a breathable DuPont Tyvek lid, such as grade 1073B, are a common sterile packaging format because ethylene oxide gas passes through the Tyvek while microbes stay out.

Lock your tray and lid materials before validation, because changing either one later can send you back through ISO 11607 testing. For retail products that don't need sterility, compare clamshell and blister formats against a folding carton before paying for tooling.

Seal Reagents in Foil and Parts in Poly

Poly bags and foil sealed bags handle the smallest components and the most moisture sensitive products in a kit. Low density polyethylene (LDPE) bags in 2 to 4 mil gauges keep screws, tubing, and accessories clean and separated, and pink antistatic versions keep static from building up around electronic parts.

Foil laminates block moisture, oxygen, and light almost completely, which is why lateral flow test cassettes ship in individual foil pouches with a desiccant sachet inside. Match the bag to the failure you're preventing: poly for contamination and loose parts, foil for humidity and light.

Print Variable Compliance Data on Labels

Compliant medical packaging carries data that changes by lot and by unit, and printing that data straight onto cartons means scrapping inventory every time it changes. FDA's UDI rule at 21 CFR 801.20 requires a unique device identifier on device labels and packages, and the Drug Supply Chain Security Act requires a 2D DataMatrix barcode with the product identifier, serial number, lot, and expiration date on prescription drug packages.

Unit level serialization stands out among healthcare packaging trends because each package now carries data a preprinted carton can't hold. Printed collateral hits the same reprint problem, as our blog on disclosure changes shows.

Print static branding on the carton, apply lot and serial data on labels, and test adhesive label performance at your storage conditions, including 2 to 8°C cold chain.

Check Credentials Before You Order Custom Medical Packaging

A supplier's certifications tell you whether its process holds up under audit, and your quality team needs copies for supplier qualification. Pharmaceutical packaging and labeling operations fall under FDA cGMP rules in 21 CFR Part 211, and ISO 9001:2015 certification shows a documented quality management system behind every run.

Oliver, Inc., for example, works to FDA cGMP and ISO 9001:2015 standards and holds G7 Master Qualification for color consistency across reprints. We stock pharmaceutical grade paperboard in multiple calipers and handle printing, die cutting, kitting, and fulfillment in house, which keeps labels, cartons, and collateral matched. Bring these questions for a packaging partner to your first call, and request certificates before you issue a purchase order.

The seven types split by job: paperboard, chipboard, and rigid boxes carry the brand, corrugated protects it in transit, and plastic, poly, and foil sit against the product itself. Custom medical packaging holds up when every layer has a named standard behind it and the data that changes lives on a label.
