Eco-Blend03/07 is a masterbatch which
degrades Polyethylene under the influence of light and
heat. The addition of 2 to 3% Eco-Blend 03/07 will produce
a photochemically and thermally degradable film.
Polyethylene containing Eco-Blend 03/07 will not degrade before
being exposed to UV light. Once the Polyethylene has been
exposed to UV light, the degradation reaction will be triggered
and continues even in the dark. It will be accelerated by
heat. Once the Polyethylene has been transformed into a fine
powder, many studies have shown that biological degradation
will take place. The end products of biodegradation will be
Carbon Dioxide and water, with a very small residue of non-toxic
inert mineral material. Biological degradation can start when
the molecular weight has been drastically reduced and when
the surface area of the disintegrated plastic has been enlarged.
The residues of degraded
Polyethylene are NON-TOXIC.

Eco-Blend 03/07 contains active metal
ions embedded in LDPE. Degradation starts only after the metal
ions have been activated by exposure to a UV light source.
The degradation speed is mainly dependent on:
- the concentration of Eco-Blend 03/07
- the thickness of the film
- the type of resin
- the presence of antioxidant and pigments
- the temperature
- the type of exposure
For mulch application, only practical tests can determine
the amount of POLYBATCH ?DEG that is required.
Practical tests must be performed to determine the optimum
Eco-Blend 03/07 is packed in Polyethylene
bags on shrink-wrapped pallets. It should be store inside
for no longer than 6 months.
The active ingredients of Eco-Blend
03/07 are approved for use in food contact applications according
to directive 2002/72/EC.
