Adopted as a packaging material for a logistics company: Long cellulose fiber reinforced resin for both CO2 reduction and strength

PLASTRON® LFT long cellulose fiber reinforced resin that combines strength and reduced environmental impact

In recent years, the logistics industry has seen a growing need for packaging materials that are strong and reduce environmental impact. In particular, it is desired to utilize sustainable materials while ensuring safety during transportation. Our PLASTRON® LFT long cellulose fiber reinforced resin offers a new solution to this need.

    

Why customers choose PLASTRON® LFT Long Cellulose Fiber Reinforced Resin

We are pleased to announce that our environmentally friendly grade, PLASTRON® LFT long cellulose fiber reinforced resin has been adopted by the logistics company Asakawagumi Unyu for a new sustainable version of their packaging product “EMUNEJI”.

EMUNEJI is a plastic item to fasten cardboard boxes for transportation. Metal fasteners may require specialized tools and skilled labor to install, but EMUNEJI can be easily installed with an electric screwdriver, thus enhancing work efficiency. In addition, since the screw tips do not stick out, this product is designed for safety during and after installation.

The main requirements of Asakawagumi Unyu in adopting PLASTRON® LFT for their sustainable EMUNEJI fasteners are as follows.

  1. High strength: sturdiness (high impact strength and rigidity) to withstand impact during transportation
  2. Sustainable: leading to reduction of CO₂ emissions
  3. Easy to use and maintain: safe to install with an electric screwdriver, etc.


PLASTRON® LFT long cellulose fiber reinforced resin meets these requirements and has passed the strict standards of Asakawagumi Unyu.

 

Made possible by long cellulose fiber reinforcement: High impact strength and excellent rigidity

When packaging materials for transportation are used for export, they must be strong enough to withstand the harsh logistics environment. However, biomass materials generally have low strength.
Our PLASTRON® LFT uses long cellulose fiber to produce higher impact strength and superior stiffness.

 

 

From an environmental standpoint, this cellulose fiber is a sustainable material derived from trees. Unlike glass fiber and metals, no residue is generated during incineration, enabling “thermal recycling” that leads to reduction of industrial waste. In addition, compared to the polyamide resin used in the standard version of EMUNEJI, this LFT grade has a lower product carbon footprint because it consumes less energy during production. The light weight of this grade also contributes to CO₂ reduction during transportation from the standpoint of secondary materials.

Furthermore, we are developing new grades utilizing PCR (post-consumer recycled) materials with the aim of further reducing environmental impact.

 

Voice of Asakawa-gumi Unyu

We have been working for several years on blending biomass materials in our “EMUNEJI”. Generally, increasing the ratio of biomass material in a product decreases its strength, but by using PLASTRON® LFT long cellulose fiber reinforced grade, we were able to develop an environmentally friendly product that retains its strength. In the future, we look forward to grades using PCR materials from Polyplastics.

 

Toward a sustainable future: PLASTRON® LFT offers three grade types

PLASTRON® LFT, which utilizes wood-derived cellulose, a biomass raw material, is available in three types of grades. For details on the features and physical properties of each type, please refer to the downloadable documents:

 

 

 

Please consider using PLASTRON® LFT cellulose reinforced resin for your packaging materials and components, as it is environmentally friendly and offers high performance at the same time.
