Pulp-Injection
Pulp-Injection at a glance
- Extensive design flexibility
- Precise, Thin, and Rigid as plastic
- Recyclable as paper*1
- Less water consumption
- Premium paper-like texture
*1 Local regulation needs to be checked.
We offer one stop solution from product design to mass production in Germany and Japan.
Material
Pulp-Injection pellet consist of mainly pulp, starch and small amount of water.
Thanks to the high pulp content (> 50%), the products are classified as non-corrugated fiberboard with PAP 21 recycling code and recyclable in existing paper recycling system.

Pulp-Injection Material
Process
Pulp-Injection production process is not ‘Thermoforming’ but ‘Injection molding’. The combination of unique material composition and our process know-how makes unique product shape and properties.
-
- Material preparation
- Pulp-Injection pellet is moisturized to be injectable into a mold.
-
- Injection molding
- The material is injected into a mold and formed.
-
- Drying in mold cavities
- The water content is vaporized in the cavity.
-
- Post trimming
- Unnecessary part is trimmed out.

Recyclability and Bio-based content
-
Pulp-Injection is classified as ‘Non-corrugated fiberboard(paperboard)’ with PAP 21 recycling code in Europe.
The products are disintegrated well in repulping process and are recyclable in a common paper recycling system according to the test results following PTS-RH 021:2012.
-
The biomass content level is 90%.
Biomass mark (90%) No.230137 certified by Japan Organics Recycling Association
