Why people are noticing corrugated plastic
1 Exceptional endurance
Ten times the endurance ability of normal paper cardboard. Corrugated plastic can be re-used over ten times more than conventional disposable cardboard.
2 Lightweight
Hollow design makes corrugated plastic far lighter than traditional molded plastic containers such as Oricon and Patacon.
Lighter burden for workers means that transport costs are reduced.
3 Waterproof
Conventional cardboard and wooden packaging deteriorate and crumble with long term exposure to moisture and wetness.
The polypropylene resin used in corrugated plastic makes for exceptional waterproofing that does not deteriorate.
High quality waterproofing means that corrugated plastic can even be used for outside signboards, etc.
4 A wealth of options
Unlike traditional cardboard, attachment of grips, handles, belts and tapes can be applied to corrugated plastic. Suitable for long term use.
5 Conductivity
A special conductive sheet in the corrugated plastic eliminates the effects of static electricity.
Provides protection not only from static electricity, but also dust absorption, making corrugated plastic ideal for use in cleaning rooms.

Choose from the twelve available colors, or request a color that matches your corporate color scheme.
Sort packages by color depending on use, or by the type of items the are stored inside.
7 Sanitary
