The KORO Premium Series Advantage

For garment bags, cosmetic bags, and premium gift bags, quality is non-negotiable. A single crease, a loose bottom card, or a burst bottom can ruin an entire batch — and your reputation.

The KORO Premium Series (T Series, TB Series, T-S Series, TB-S Series, A Series, and KL Series) was designed specifically for high-end paper bag production. It doesn't just make bags — it makes perfect bags, every time.

Laminated Paper Bags No Longer Go to Waste

Laminated paper is tricky. On traditional equipment, when the tube turns over during forming, the paper creases. Once creased, the bag is ruined — and so is the entire batch.

The Premium Series solves this with a 23-meter patented linear production line. Instead of bending and turning, the tube moves straight through the forming process.

What this means:

• Zero creases on laminated paper

• Zero scrap from crease-related rejects

• Consistent quality across every bag, every run

For luxury brands that demand flawless packaging, this isn't just an advantage — it's a requirement.

Zero Bottom Card Drop — No More Jams or Downtime

Bottom cards are essential for premium bags — they provide the structure and strength that luxury packaging demands. But on traditional machines with vertical stations, bottom cards frequently fall out during production, causing jams, downtime, and frustrating delays.

The Premium Series features angled dual stations with a mini-cylinder push-flat design.

The result:

• Bottom card drop rate reduced by 90%

• 30% higher efficiency — less downtime, more output

• Consistent bottom card placement — every bag, every time

No more stopping production to fish dropped cards out of the machine. No more wasted bags from misaligned bottom cards.

Zero Bottom Burst — Bottom Inlet Design Prevents Bursting

Here's a subtle but critical difference: most traditional machines use top inlet for bottom pasting. The result? Air gets trapped inside the bag during forming, and when the bottom is sealed, the trapped air causes bursting.

The Premium Series uses bottom inlet design — air escapes naturally during the forming process, so the bag seals cleanly every time.

What this means:

• Zero bursting during bottom pasting

• No air-trapped rejects

• Higher yield from every production run
