Private label sheet masks and sheet mask OEM in Korea

Brands work with GDK on masks in three ways. For private label sheet masks, our R&D and design teams develop the essence, sheet and pouch for your brand (ODM). For sheet mask OEM, you bring the specification or formula and we procure materials and manufacture in Korea under CGMP, ISO 22716 and ISO 9001. Or start from one of GDK's ready-to-market mask formulas and customise texture, scent, claims and pouch. Compare OEM and ODM.

Fingerprint-free, automated mask production

No worker's hand touches the product.

Mask quality depends on hygiene as much as on the essence. GDK runs a six-step automated line in which no worker's hand touches the product — which is why we call it the fingerprint-free process:

  1. Automated cutting of the mask sheet
  2. Automated folding
  3. Automated insertion into the pouch
  4. Automated filling of the essence on pouch filling lines
  5. Automated packaging into unit cartons
  6. Automated wrapping to completion

The process runs inside a CGMP-certified site (all processes) and is supported by raw material and packaging inspection before production. Read about our quality system.

Patented mask technologies

Biodegradable sheet mask packaging – Patent No. 10-2390469

Mask packaging is single-use by nature. GDK developed and patented a mask kit packed in biodegradable packaging material, so brands can reduce the environmental footprint of their mask line without giving up the sheet format. This technology reflects the sustainability principle of GDK's Great Innovation standard.

Peel-off pack with whole botanicals – Patent application 10-2019-0063226

GDK has filed a patent application for a cosmetic composition for peel-off packs that contains natural materials such as flower petals in their original form. The botanicals stay visible inside the formula, adding visual appeal and letting consumers see what they are applying.

Wash-off mask formulas you can launch

Two of GDK's ready-to-market formulas are wash-off masks inspired by traditional Korean ingredients:

  • Rice Sediment Mask – made with rice lees extract from makgeolli brewing, with a texture and scent that recall the lees themselves. It keeps the skin moist while on and gently removes dead skin cells and impurities when rinsed off.
  • Mugwort Moxibustion Cream – a green gel that turns into a white cream as you massage it, with a warming feel. Made with mugwort leaf extract to soothe sensitive skin, it leaves the skin texture smooth after rinsing.

From concept to shipment

Your mask project follows GDK's 10-step development process: we identify your needs, design the product, sign an NDA and agree on quality tests, develop the concept, sheet, essence and pouch, assess usability, compatibility, stability and safety, confirm the final version, schedule production, inspect materials, produce and deliver — with marketing support after launch.

Frequently asked questions

How many sheet masks can GDK produce?
GDK's capacity for mask and patch products is 460,000 units per day, or about 10 million units per month.
Which mask types can you develop?
Sheet masks, bubble-type sheet masks, spot patches, peeling pads, peel-off masks, wash-off masks and sleeping masks. The formula and format are developed around your brand's needs.
Are the masks touched by hand during production?
No. GDK's fingerprint-free process automates cutting, folding, insertion, filling, packaging and wrapping, so the sheet and essence are not handled by workers.
Can you offer eco-friendly mask packaging?
Yes. GDK holds Korean patent No. 10-2390469 for a mask kit packed with biodegradable packaging material, and can propose it for your mask line.
Can I order a peel-off mask with real flower petals?
GDK has filed a patent application (KR 10-2019-0063226) for a peel-off pack composition containing whole botanicals such as flower petals, which remain visible in the formula. Ask our team about developing this format for your brand.
