Core Advantage · Short Runs

HP Indigo 200K Digital Printing

The HP Indigo 200K digital press is a core competitive advantage for short-run, multi-design flexible packaging. It allows small batches and several designs to be produced without traditional gravure cylinders.

Purpose: New product launches, market testing, seasonal packaging, sample bags and small SKU batches.

  • No gravure plates or cylinders for digital jobs
  • Multiple designs or SKUs in one order
  • Fast artwork revisions and shorter turnaround
  • Suitable for hundreds to a few thousand pieces

High Volume · Bulk Orders

Gravure Printing

Traditional rotary gravure printing for large-volume repeat orders, where unit cost and long-run color stability matter most.

Purpose: Established products and repeat bulk shipments that benefit from a lower per-unit price.

  • Lower unit cost at high volume
  • Stable, consistent color across long runs
  • Vivid, durable printed layers
  • Commonly suited to orders above roughly 10,000 pieces

Material Structure

Lamination

Two or more film layers are bonded together to build the barrier and mechanical structure required for the product.

Purpose: Combining barrier, print, seal and strength functions in a single flexible web.

  • Custom barrier against moisture, oxygen and light
  • Different film functions combined in one structure
  • Structure matched to product shelf life and regulations
Curing room with laminated film rolls conditioning after lamination
Bond Stabilization

Curing

Laminated rolls are held under controlled conditions to stabilize the adhesive bond before pouch making.

Purpose: Ensuring the layers stay bonded through downstream processing and the product's shelf life.

  • Stable adhesive bonding after lamination
  • Reduces the risk of delamination
  • Consistent performance in later production stages
