Frosted Finish

At Serigrafia Portal, we specialize in acid etching techniques, offering a key added value to the industry and a significant competitive advantage across the sector.

In our acid etching unit, we deliver finishes with a sophisticated, ultra-smooth matte texture that elevates the perceived value of every container.

An additional key benefit of acid etching is its critical role in pre-production quality control. By performing etching techniques in-house, we treat glass impurities and microcracks, guaranteeing a flawless surface and complete traceability before advancing to final decoration.
