Six pouch formats cosmetic brands actually use.
The format that sells the sample.
Flexible packaging is where beauty brands win on two fronts at once: it is the lowest-cost, lowest-waste way to package sheet masks and samples, and the sample sachet is the single most powerful customer-acquisition tool a brand has. The catch is barrier and seal integrity — a weak laminate or a bad seal lets serum oxidise or leak, and the consumer blames the product, not the pouch. Vella routes each pouch format to factories with the right film structure and seal validation, and verifies barrier and burst testing before production is approved.
Flexible pouches, with numbers.
A printed sheet-mask pouch (about 4 × 10 cm) carries an industry floor of around 100,000 pieces per design at large converters and around 30,000 at smaller ones, with gravure cylinders at RMB 850–1,500 (≈USD 120–210) per colour and a 15–20 day cycle with ±10% over- or under-run. Pouches on stock film with custom print run 25–35 days; a custom structure or spout tooling 55–75 days. The pass marks are numeric: top seal ≥60 N/15 mm, side seals ≥65 N/15 mm, spout and tube-style seals ≥20 N/cm, and on foil structures oxygen and moisture transmission ≤0.1 per m² per 24 h.
Specification: pouch formats, sizes and structures
| Format | Typical size / fill | Structure | Features | Where it fits |
|---|---|---|---|---|
| Sheet-mask pouch (3-side seal) | About 4 × 10 cm folded mask in a 100–160 mm pouch; 20–30 ml serum | PET / AL / LDPE pure-foil laminate (gravure print on the PET face); VMPET metallised alternative | Tear notch; matte or gloss top film; single-dose | Sheet masks, under-eye patches |
| Sample sachet (flat, 3- or 4-side seal) | 5 × 7 cm (6 g) · 6 × 8 cm (8 g) · 6 × 9 cm (10 g) | PET / AL / PE for barrier; mono-PE for recycle-ready | Tear notch; roll-film for form-fill-seal lines | Serum, lotion, shampoo, cream samples |
| Stick pack | 1–15 ml | PET / AL / PE or PET / VMPET / PE | Vertical form-fill-seal | Single-dose serum, ampoule alternative |
| Stand-up pouch (doypack) | 50–500 g | PET / PE, kraft / PE, mono-PE, PCR laminate | Bottom gusset; resealable zipper; hang hole | Bath salts, scrubs, powder masks, solid refills |
| Spout pouch | 100–1,000 ml | PET / PE or mono-PE laminate; barrier layer where needed | Spout and screw cap sized to pour into the bottle neck | Shampoo, body wash, lotion, hand-wash refills |

Barrier structures: what each film actually blocks
| Structure | Oxygen / moisture barrier | Recycle status | Cost position | Use it for |
|---|---|---|---|---|
| PET / AL / LDPE (pure aluminium foil) | OTR ≤0.1 cc/m²·24 h; WVTR ≤0.1 g/m²·24 h (mask-pouch standard, GB/T 1038 / 1037) | Multi-material; not kerbside-recyclable | About 30% higher unit price than metallised | Sheet masks, serums, anything light- or oxygen-sensitive |
| PET / VMPET / PE (metallised) | Good, below foil; pinholes matter | Multi-material | Baseline foil-look pouch | Samples, wipes, powders |
| PET / EVOH / PE (PBL-type, foil-free) | High: EVOH passes oxygen at roughly 0.2 units versus 150–300 for single-layer PE (tube data) | Foil-free, metal-detectable | Mid | Oil- or fragrance-led formulas that want a squeeze-back, foil-free look |
| Mono-PE or mono-PP laminate | Light: OTR in the 150–300 range for PE | Recycle-ready where the market stream accepts it | Baseline | Refill spout pouches, doypacks for wash-off products |
| Kraft / PE or kraft / VMPET / PE | Light to medium | Multi-material unless mono-PE with a paper look | Baseline to mid | Powders, bath salts, natural positioning |

Compatibility: which formula goes in which structure
| Formula | Recommended structure | Hard rule |
|---|---|---|
| Sheet-mask serum (water-based, often with actives) | PET / AL / LDPE pure foil | Foil for light and oxygen; irradiated lots need the certificate |
| Serum with vitamin C, retinol | Foil, or PET / EVOH / PE | Needs the barrier: EVOH ~0.2 versus 150–300 for PE |
| Toner or mist above ~30% ethanol | Foil laminate with PE sealant; test the sealant | Never a PET contact layer for the bulk — PE sealant inside |
| Facial oil, essential oils | Foil with a PE sealant; check ink and adhesive | Essential oils extract plasticisers and lift ordinary inks — run the 48°C / 30-day test |
| Shampoo, body wash, lotion refills | Mono-PE spout pouch | Spout sized to the bottle neck; seal and burst on sample batches |
| Powders, bath salts | Stand-up or flat-bottom, kraft / PE or mono-PP with zipper | Moisture seal; WVTR matters more than OTR |
| Wet wipes (alcohol or fragrance) | PET / PE with resealable label | Check the label adhesive against the lotion |

Barrier data for foil, EVOH and mono-PE structures is tabulated on cosmetic tube specifications, and the formula rules on the compatibility matrix. Refill spout pouches for wash-off products sit in the haircare and bodycare solution; sachets and mask pouches for treatment lines in the skincare solution. The test battery is on cosmetic packaging quality standards; supplier screening on how to evaluate a China packaging supplier. Sibling formats: cosmetic tubes, HDPE shampoo bottles and refillable packaging.

Four things that decide whether a pouch performs.
A pouch looks simple, but the things that fail are invisible until they fail — barrier, seal, leak and recyclability. We test for them before production, not after.
Barrier structure
Sheet-mask serum and active formulas oxidise without the right barrier. We match the film structure — aluminium-foil, metallised PET or transparent high-barrier — to your formula's oxygen and light sensitivity, not to whatever the factory runs by default.
Seal & burst integrity
A pouch is only as good as its weakest seal. We require seal-strength and burst testing on sample batches so a pouch survives filling, shipping and the consumer's hands without leaking.
Fill & format match
Powders, scrubs, thin serums and thick lotions each need a different pouch style, gusset and closure. We spec the format to your fill and filling line — including spout and fitment compatibility — before tooling.
Recyclability that's real
A "recyclable" pouch with a mixed aluminium laminate isn't recyclable. Where you need a recycle-ready claim, we route to mono-material PE or PP structures and verify the full laminate is compatible before approving production.
