When is a 4-side-seal bag better than a 3-side-seal bag?

Whenever dimensional stability, uniform edge appearance or high seal strength matter, for instance with premium packaging, heavy contents or sharp-edged products.

What is a centre bottom seam?

An additional seal running across the middle of the bag base. It stiffens the bottom and improves stability without a bottom gusset.

Can paper-based laminates be processed?

Yes, provided they are heat-sealable. For purely paper-based sterile packaging the DLP-600 medical paper/plastic configuration is the appropriate machine.

What defines this machine

Continuous perimeter seal

All four edges are sealed, giving a dimensionally stable rectangular bag with uniform appearance, which is why premium brands choose this format.

Centre bottom seam for stability

The centre seam stiffens the base. The bag keeps its shape on the shelf without needing a bottom gusset.

High seal strength

Four sealed edges distribute the load. With heavy or sharp-edged products this format withstands considerably more than a 3-side-seal bag.

Serviceable classic line

Panasonic PLC with touchscreen, stepper motors and magnetic powder brake. Proven components with good spare-part availability in Europe.
