윗물이 맑아야 아랫물이 맑다

«If the upstream water is clear, the downstream water will be clear too»

— Korean proverb

Our QC system starts with incoming raw-material control. Every production stage is a check of the 'upstream' for the next step.

Quality control process

6 steps — from raw material to shipping

  1. 1

    Incoming raw-material control

    Every batch of raw materials is verified against supplier certificates and our own measurements — nothing unchecked enters production.

  2. 2

    In-process control

    At critical points of the line — extrusion, printing, thermoforming — operators record parameters per checklists.

  3. 3

    Intermediate control

    Between major operations, sample measurements confirm that the intermediate product meets the spec.

  4. 4

    Final QC

    Finished product undergoes final inspection: dimensions, color, strength, compatibility with the customer's packaging lines.

  5. 5

    Laboratory testing

    For selected batches — mechanical, color, and thermal tests. On request — RoHS verification and MSDS documentation.

  6. 6

    Batch passport

    Every batch ships with a document recording the control results. Full traceability back to raw material.

R&D and development

We don't just produce — we develop

Clients come to us not only for standard products. When a task requires a material that doesn't yet exist on the market — we create it.

Joint case with a home-appliance manufacturer and Polyplastic: we developed a dielectric plate based on RP black — RoHS-compliant, with a V=0 flammability rating. The solution passed testing and went into series production.
