Glutathione Vial Boxes

Packaging for light exclusion

When a customer specifies that a product must be protected from light, the packaging can contribute in specific, measurable ways — and it is worth being precise about what those are rather than making a general claim.

• Opaque board — A carton with no window and sufficient caliper blocks visible light when closed.
• Avoiding windows entirely — The most common decision; a window defeats the purpose of an opaque carton.
• Dark inside surface — An inside-printed dark panel reduces internal reflection.
• Full closure — A carton with tucked or glued flaps rather than an open tray.
• Secondary carton — An outer carton adds a second barrier for transit and storage.

What we will not do is state that a carton provides a specific level of light protection for your product. That depends on the vial itself, the storage conditions and your own testing.

Two-component packs

A powder vial and a solvent vial are rarely the same size, which makes a symmetrical insert the wrong answer.

• Independent cavity sizing — Each vial cut to its own diameter and height rather than to a compromise.
• Dividing wall — Board or foam between the two so the glass cannot make contact.
• Depth staggering — Cavities set at different depths so both vials finish level at the top.
• Position marking — Printed labels or numbers so the two are not confused.
• Optional syringe channel — Where the pack also carries a transfer or reconstitution device.

The full logic for cavities holding unlike components is set out on the 2-vial kit boxes page.

Formats we build

• Single-vial carton — One powder vial, die-cut insert, opaque board.
• Powder plus solvent pair — Two cavities, dividing wall, printed positions.
• Three- and five-count sets — Matched vials supplied together, in a partitioned carton.
• Clinic multi-packs — Ten-count cartons for practitioner supply, usually plain and over-labelled.

Most of these sit on a 5ml or 10ml footprint, so the cavity and carton guidance on the 5ml vial box page applies directly.

Materials

• SBS paperboard — The standard; at a sufficient caliper it is fully opaque.
• Kraft paperboard — Naturally opaque and lower cost, with limited print contrast.
• Rigid chipboard — For presentation packs; the greyboard core is entirely opaque.
• Metallised or foil-lined board — Where an additional barrier is specified by your own requirements.
• Recyclable paper-based stock — Available where no metallised layer is used.

Opacity is a function of caliper and coating rather than colour, and a light-coloured board can be entirely opaque — see the board grade reference.

Inserts

• Two-cavity die-cut platform — The economical option for a paired pack.
• Two-cavity foam block — More protective, and easier when the two vials differ significantly.
• Folded partition — A simple board wall creating two isolated cells.
• Formed tray — Where the two components must sit at controlled heights.

Printing and finishing

• CMYK process — For full-colour clinical or aesthetic-market artwork.
• PMS spot colour — For consistent brand colour, particularly on solid backgrounds.
• Inside printing — A dark inner panel reduces internal reflection and can carry position labels.
• Matte lamination — Reduces glare; also accepts applied labels reliably.
• Spot UV and foil — Used sparingly, usually confined to a logo.

Vial labels for paired packs

• Visually distinct labels — The powder and solvent labels should be immediately distinguishable at a glance.
• Consistent brand, different colour block — The usual solution — same design, clearly different accent.
• Variable data — Batch and lot fields printed per unit.
• Moisture resistance — For vials that may be refrigerated and handled with damp hands.

Ordering

• 1. Send both vials — The powder vial and the solvent vial, plus any device that shares the pack.
• 2. State any light requirement — Tell us if opacity is a specification, and we will keep windows out of the design.
• 3. Structure and insert — Specified against the two components and the count.
• 4. Die line, proof, sample — A loaded sample with both vials seated.
• 5. Production — Printed, cut, glued and packed flat, with inserts supplied to match.

Artwork responsibility

• We print what you supply and approve; we do not author packaging content.
• We do not review artwork for regulatory compliance or required statements.
• Our checks cover production issues only.
• Determining what your packaging must show is your responsibility.

Quality control

• Both cavities are fit-tested with their actual vials, not with one representative sample.
• Wall thickness between cavities is verified.
• Cartons are checked for full closure with no light gaps at the flaps where opacity is specified.
• Colour is checked against the approved proof.
• Loaded samples are inverted and shaken.

Packaging supply scope

• Peptides Boxes manufactures empty cartons, inserts, trays and labels only.
• No glutathione, solvent, diluent, medication or vial content is supplied with any order.
• We make no claims about the stability, safety or efficacy of anything a customer packs.
• Legal, labelling, testing, storage, shipping and regulatory responsibility rests with the customer.
