Sheet Mask OEM FAQ: Fabrics, Serum Volume, and MOQ

What materials are sheet masks made from?

The most common carriers are cotton, rayon, and non-woven fiber blends, with newer options such as bio-cellulose, hydrogel, and micro-fiber. Cotton and rayon feel soft and hold serum well; bio-cellulose hugs the face and gives a cooling, gel-like feel but costs more; hydrogel masks are peel-off formats rather than soaked sheets. The right choice depends on the experience you want and your price point, so ask your OEM partner to send samples of each material.

How much serum is in a sheet mask?

Typical masks hold between 20 and 30 ml of essence per sheet, and many suppliers target a middle figure as the standard fill. Concentrated or premium masks sometimes carry more, but the sheet material itself sets a practical limit on how much serum it can hold without dripping. What matters more than raw volume is formula quality and even saturation, so ask for a consistent fill weight and a preservative system suited to a high-water formula.

What is the MOQ and lead time for custom sheet masks?

MOQs depend on whether you choose existing mask shapes and stock serum formulas or request custom shapes, custom fabrics, and custom formulas, since custom elements raise the MOQ. Lead time includes serum development, stability testing, cutting the mask to shape, printing the pouch film, filling, sealing, and quality control, so plan for several weeks from approval to delivery plus shipping time. Confirm both MOQ and lead time in writing before you start.

What production steps are involved in sheet mask OEM?

The process runs from formula development and stability testing, through sourcing and cutting the sheet fabric, printing and slitting the pouch film, filling the serum into the pouch, inserting the mask, and sealing, then coding, batch testing, and cartoning. A reputable OEM follows GMP and documents every batch so raw materials and quality-control results are traceable. Ask to see the production flow and batch records during a factory audit.

How do I keep sheet mask quality and safety consistent?

Sheet masks are high-water, high-exposure products, so the essentials are a validated preservative system, microbiological testing of every batch, sealed pouches with correct fill weights, and storage away from heat and sunlight. Work with an OEM that follows GMP standards and can provide certificates of analysis and safety documentation for each batch. Also run your own stability checks at agreed intervals after production rather than only at launch.
