Packaging machine
- Onpack series

Flexible packaging is the most environmentally friendly packaging form with the least environmental impact. Orihiro is working to enhance the benefits of flexible packaging and adapt it to a sustainable society, such as reducing the weight of resin, making it more compact, reusing it, and recycling it.

Aseptic filling and packaging system / Gas type aseptic filling and packaging system

The aseptic filling and packaging system completely protects food from harmful microorganisms and enables storage, distribution and sale at room temperature. The gas aseptic filling system is an epoch-making system that can sterilize packaging materials and filling machines at low temperature with hydrogen peroxide gas. Unlike the conventional wet sterilization method using liquid hydrogen peroxide solution (wet type), the sterile environment can be maintained dry.

Pillow pouch packaging

This is a basic packaging form that represents Orihiro's packaging machines. Orihiro's machinery was a pioneer and is used as a delivery container for restaurant chains and fast food around the world.

Stand up pouch packaging

It is a popular packaging form with a high display effect. Onpack's stand up pouch filler has the flexibility for pouch shapes and sizes, design cut, spout shapes, etc.

T-pouch packaging

This is a packaging form originally developed by Orihiro. It features a straight cut, which makes it easy to open and there is no need to worry about dripping when opening. It is an eco-friendly pouch that can reduce the cost of the spout because it has a spout shape that can be drunk directly from the mouthpiece.

Four-side seal packaging (three-side seal packaging)

"three-side / four-side seal pouch" suitable for various food packaging including retort foods.

Total system with packaging machine

We provide total support for the construction of optimal production lines, from consultations on automation and mechanization to planning of food processing plants including packaging machines.
