Why KORO Is China's National Industry Standard Drafting Unit for Sheet-Fed Paper Bag Machines

In China's paper bag machinery industry, there's one distinction that sets a manufacturer apart: being named the National Industry Standard Drafting Unit.

KORO (Wenzhou Koro Machinery Co., Ltd.) holds this designation for sheet-fed paper bag machines. It means the standards that govern the entire industry were written with KORO's expertise — a responsibility that only a handful of manufacturers earn.

But how did KORO earn this distinction? And what does it mean for you as a buyer?

From 2008 to Industry Leadership

Founded in 2008, KORO has spent over 16 years perfecting the art of paper bag machine manufacturing. The company specializes in sheet-fed and roll-fed paper bag making machines, serving medium and high-end handbag manufacturers worldwide.

Over that time, KORO has accumulated:

• 75+ state patents, including 17 invention patents

• ISO/SGS certification and European Union CE certification

• Recognition as a National High-Tech Enterprise

• Recognition as a Zhejiang Provincial Sci-Tech SME

These aren't just badges on a wall. They represent thousands of hours of R&D, countless design iterations, and a relentless commitment to quality.

What "National Industry Standard Drafting Unit" Actually Means

In China, industry standards are not written by government committees alone. They are developed in collaboration with the country's leading manufacturers — the companies with the deepest technical expertise and the most rigorous quality systems.

KORO is one of those companies.

What this means for you:

• Proven technical expertise — KORO doesn't just follow standards; it helps define them

• Rigorous quality systems — the same systems that earned KORO its standard-drafting status are baked into every machine

• Industry-recognized reliability — when the industry looks to KORO for standards, you can trust that KORO's equipment meets the highest benchmarks

Innovation That Sets the Standard

KORO's commitment to innovation isn't just talk — it's backed by concrete achievements.

In 2020, KORO developed and manufactured a fully automatic paper bag making machine equipped with automatic reinforced cardboard pasting at the bag mouth, inserting-type top folding, and hole punching. This machine was named the "First Set" Product in the Key Areas of Equipment Manufacturing in Wenzhou City — a prestigious recognition that few manufacturers achieve.

This wasn't a one-time achievement. KORO has consistently pushed the boundaries of what paper bag machines can do:

• T Series: Full automatic paper bag machine with top card pasting, top folding, and hole punching, handling paper thickness from 100–300gsm at speeds up to 78 bags per minute

• TB-S Series: Fully automatic machine integrating top card and bottom card pasting in a single production line

• H Series: Stacked design enabling 15-minute changeover between twisted and flat handles, with synchronized zero-waste technology

Each innovation is protected by patents — 75 of them, with 17 classified as invention patents
