NFC packaging materials, explained.
Behind every great NFC pack is a stack of quiet decisions: which chip, which antenna, which substrate, which finish. This guide walks through the tradeoffs so you can spec NFC packaging that performs in every environment your product ships into.
The three parts of an NFC inlay
- The chip. A tiny silicon die (a fraction of a millimetre) that stores the URL and, in secured variants, produces a cryptographic signature on every tap.
- The antenna. A copper or aluminium coil, usually 20–35mm across, that harvests power from the phone and communicates with it.
- The substrate. A thin PET or paper layer the chip and antenna sit on before being laminated into your pack.
Choosing a chip
- NTAG 213 — most popular; 144 bytes; ideal for a URL plus small metadata. Lowest per-unit cost.
- NTAG 215 — 504 bytes; useful when the tag itself carries structured data beyond a URL.
- NTAG 216 — 888 bytes; the choice when you want to store rich payloads on the chip.
- NTAG 424 DNA — cryptographic authentication. Every tap generates a unique server-verifiable signature. The default for anti-counterfeit and luxury.
Antenna size and read range
Larger antennas read from further away and are more forgiving of off-axis taps. A 30mm+ round antenna in a hangtag or insert reads reliably at 2–4cm; a smaller 12mm antenna in a compact label reads only when the phone is touching the tag directly. Match antenna size to the physical space you have and the tolerance you want at point of interaction.
Substrates by use case
- Paper & cardboard — the default for hangtags, cartons and inserts. Compatible with standard paper recycling.
- PET — thin, durable, moisture-resistant. Used for labels, seals and outdoor packaging.
- Fabric & woven labels — the inlay is sandwiched between fabric layers, ideal for premium apparel.
- On-metal inlays — ferrite-backed to work on aluminium cans, foil pouches and metallic surfaces where a standard inlay would be detuned.
Finish and durability
NFC inlays survive normal handling — but you can specify a matt/gloss overlaminate, UV varnish, foil stamp or emboss over the chip area without affecting performance. Avoid metallic foils directly over the antenna; they can shift the resonance and reduce read range.
Sustainability considerations
Paper-substrate inlays are the most easily recycled option and are increasingly used by brands with EPR (extended producer responsibility) obligations. The chip itself is small enough that it does not disqualify a pack from paper or cardboard recycling streams in most jurisdictions.

Frequently asked questions
Which NFC chip should I use for packaging?
For most content and marketing experiences, NTAG 213 or NTAG 215 is ideal — cheap, universally readable and enough memory for a URL plus metadata. For authentication and anti-counterfeit, use NTAG 424 DNA, which signs each tap cryptographically.
Can NFC chips be printed onto standard packaging?
The chip and antenna come pre-assembled as an inlay and are laminated into hangtags, labels or cartons during finishing. Any converter or packaging printer can integrate them; the design of your pack does not need to change.
Does the packaging material affect NFC performance?
Yes. Paper, cardboard, plastic and fabric all work well. Metal blocks NFC unless you use a ferrite-shielded on-metal inlay — this matters for aluminium cans, foil pouches and metallic labels.
How durable are NFC chips inside packaging?
A properly laminated NFC inlay survives normal retail handling, shipping, temperature swings and light moisture. For outdoor or wet environments, we recommend PET-encapsulated inlays and a protective overlaminate.
