Pharmaceutical packaging where the barrier and the paperwork both matter
In pharmaceutical packaging the specification is not finished when the pack performs. It is finished when the performance can be evidenced — material declarations, batch traceability, tamper evidence and a change-control trail that shows the pack shipped this year is the pack that was qualified. We supply against that, not around it.
Aluminium structures with a complete barrier
HDPE containers with induction-sealable necks
Desiccants in pharmaceutical-grade sachets
Serialised and void-on-removal labels
What this category requires of a pack
Four requirements that come before the commercial ones.
The barrier has to be absolute, not good
Many actives degrade measurably in the presence of moisture or oxygen, and the shelf life is a registered figure rather than an estimate. Aluminium foil is the only flexible material that excludes both completely, which is why it remains the reference here regardless of cost.
Tamper evidence is not optional
Induction liners, void-on-removal labels and fragile substrates all exist to make interference visible. Which one applies depends on the format and the market, and it is specified rather than chosen at the end.
Traceability runs to the unit
Serialisation — a unique, checkable identity on each pack — is mandatory in a growing number of markets and is what defeats both counterfeiting and diversion between territories. It is a data question as much as a printing one, so it is specified with the label.
Change has to be controlled
A substituted film, a different adhesive or a new lacquer is a change to a qualified pack. We quote the structure and supply the declarations for it, and we say when something is not the same thing.
Formats for pharmaceutical packaging
The formats and components this category orders.
Aluminium foil film
A complete barrier to light, oxygen and moisture, in soft or hard temper, lacquered where the face needs protection.
Four side seal pouch
Sachets and unit doses with an aluminium ply, flat and stiff enough to handle and machine-fill.
HDPE bottle
Chemically stable, very low permeability, opaque, with a neck finish matched to your induction sealer.
PP bottle and cup
Heat tolerant to 100 °C and reliably sealed to a foil lid, for tablets and capsules.
Desiccants
Silica gel and clay in food- and pharmaceutical-grade sachets, sized to the sealed volume.
Security label
Void-on-removal, fragile-substrate, holographic and serialised QR, printed with variable data.
Structures that suit it
PET/AL/PE remains the reference flexible structure: the aluminium ply excludes light, oxygen and moisture completely, and the PET outer takes the print and the handling. For rigid packs, HDPE gives the lowest permeability of the common polymers and is chemically inert against most formulations, with PP where heat tolerance is needed. Lacquers on metal components are chosen against the formulation rather than by default. See aluminium foil film and materials and structures.
What has to be provable
This is the category where quality and compliance stops being a page and becomes the product. Material declarations to FDA and GB standards travel with every order. Beyond that, what a pharmaceutical buyer needs is consistency that can be demonstrated: the same structure, the same supplier, the same lacquer, batch after batch, with documentation that survives an audit. Serialisation and anti-counterfeit requirements differ by market and are specified before the label is designed, not after. Export packaging compliance covers what travels with the goods.
The rules themselves are public: FDA 21 CFR 177, the US list of permitted food-contact polymers.
Questions we are asked about pharmaceutical packaging
Can metallised film replace foil here?
Rarely. Metallised PET is a very good barrier; foil is a complete one, and it does not develop pinholes under flex. For a registered shelf life on a moisture- or oxygen-sensitive active, foil is usually what the dossier says.
Do you supply pharmaceutical-grade desiccants?
Yes — silica gel and clay in sachet materials suitable for direct contact, sized against the sealed volume, the pack barrier and the shelf life rather than against the container size.
What tamper evidence do you offer?
Induction-sealable liners for bottles, void-on-removal and fragile-substrate labels for cartons and closures, and holographic films where a visual check by a patient or pharmacist is wanted.
Can you serialise labels?
Yes, with variable-data printing and a serialised QR or code per unit. How the numbers are generated and verified is part of the specification, so tell us the system you are using.
Will you tell me if a substitution changes the pack?
Yes. A different film, adhesive or lacquer is a change to a qualified pack, and we say so rather than shipping the nearest equivalent.
Do you publish prices?
No. Structure, volume, printing and compliance requirements change the price, so everything is quoted against a specification.
Send the specification, and the standard it was written to
Registered shelf life, the sensitivity of the active and the markets it ships to decide the structure. Send those with any existing specification and we will quote against it rather than around it.
Key Information
In pharmaceutical packaging the specification is not finished when the pack performs — it is finished when the performance can be evidenced, with material declarations, batch traceability and tamper evidence that a regulator will accept.
- Material declarations and batch traceability are part of the specification, not an afterthought.
- Tamper evidence is a requirement rather than an option in most markets.
- Moisture limits are typically the tightest of any category.
- Aluminium foil structures are used where a near-zero barrier is required.
- Documentation requirements differ by market, so the destination is part of the specification.
What makes pharmaceutical packaging different?
The evidence. A pack that performs is not enough; the material declarations, the batch traceability and the tamper evidence all have to stand up to a regulator.
What barrier do pharmaceutical packs need?
Often the tightest in the catalogue. Aluminium foil structures are used where moisture ingress has to be near zero.
Does the destination market change the specification?
Yes. Documentation and labelling requirements differ by market, so the country of sale is part of the specification rather than a shipping detail.
