How does a vacuum compression bag work?

The goods are inserted, the zipper closed and air extracted through the valve with a vacuum cleaner or compressor. The valve prevents backflow so the reduced volume is maintained.

How much can volume be reduced?

It depends on the contents. Loose bedding compresses strongly, densely packed textiles much less. There is no universally valid figure.

Why is zipper tightness so critical?

A leaking zipper lets air back in and the bag refills within hours. Tightness therefore determines the entire function of the product.

DLP-1300: vacuum compression bags with zipper and valve

The DLP-1300 vacuum compression bag machine produces large 3-side-seal bags with zipper and vent valve. These bags substantially reduce the volume of compressible goods such as textiles and bedding, cutting storage and transport costs.

What defines this machine

Zipper and valve combined

The zipper closes the bag, the valve lets air escape and prevents backflow. Both elements are applied on the same machine.

Large formats

The 1300 frame delivers the bag sizes needed for bedding, pillows and textile packs, well beyond typical food-bag formats.

Zipper tightness as the core requirement

On compression bags zipper tightness decides function: a leak means the bag refills within hours. Zipper position and sealing are therefore tightly controlled.

Robust classic drive line

Panasonic PLC with touchscreen, stepper motors and ultrasonic web guiding. Built for continuous operation with thicker laminates.
