EVOH for pesticide packing
   EVOH can be regarded as EVA (ethylene—acetic
acid ethylene ester copolymer) modified material. It has both
ethylene polymer good process capability and vinyl alcohol
polymer high gas obstruct capability. It is a new colorless,
transparent obstruct material, with PVDC and PA, these three
materials are the best barrier resin in the world. Its gas
obstruct capability is **0 times higher than PA, ****0 times
higher than PE,PP and ten times higher than PVDC which high
obstruct material we used very often. In dry or relative humidity
condition, its permeability is extremely low, but its gas barrier
capability is *0 to *0 times or even more times higher than
Nylon. EVOH has excellent transparency, glossiness, mechanical
strength, retractility, abrasive resistance, freeze resistance
and surface strength. It has the highest heat stability in all
the barrier resins. It also has excellent oil resistance, organic
solvent resistance and antistatic capability. It can regenerate
and does not contain Chlorine and Dioxin,it is to be called green
environmental production. According to the use of soft packaging,
you must considered the material process capability and physics
capability, to choose *0 to *0 times EVOH as the barrier layer,
not only prevent oxygen and water vapor infiltrating into the
content, but also chain up the aroma, fluid juice and the solvent
of the content. Thus it solved the problem that the contents
(liquid, gas) dissolved the compound water glue. In some areas,
the EVOH has gradually replace the metallized film, aluminum foil
and rigid container. It is being received various countries
attention and shows the best potential growth trend in the
market. Due to the oxhydryl in the molecular structure of EVOH
resin, EVOH resin has the hydrophilia and hygroscopicity. When it
adsorb the damp, its gas obstruct capability will be affected. So
EVOH is used as the middle layer, usually coated with polyolefin.
The damp quantity can be control aboratively, to use multilayers
coated technic to packing EVOH resin (such as polyolefin).
   After many years research, we discovered that
if we select the international import raw materials, use the
latest co-extruded process flow, the production which contains
the EVOH high obstruct ability. Then compound many kinds of base
materials like PE, PP, PVC, polystyrene, PET, PA and so on. The
Oxygen transmission rate can be reduced to a small percentage
even one thousandth. According the requirement of the obstruct
effect, it can be coated on single side or double sides or even
multilayer coated. The production of multilayer coated film for
the automatic liquid filling machine, not only solved theÂ
moisture absorption problem, but also had a good economical
efficiency. To each kind of active ingredient, the low
adsorbability, high obstruct capability, it can prevent the loss
of effective component; the excellent oxygen resistance, can
prevent the oxidation and metamorphism of the effective
component; the excellent transparency, can be applied to the
oxygen sensitive goods. The packaging content can be solid
granules, powdery products, fluid products.
Â
Chemic and oil resistance capability
   EVOH compound film has excellent oil
resistance and organic solvent resistance. Put it in the liquor
and oil in the *8 degree F. A year later, the increased
percentage of the weight is : cyclohexane, xylene, petroleum
ether, benzene and acetone is 0% ; glycol is 2.3% ; methanol is
*2.2%; salad oil is 0.1%.
Thermal/ Mechanical Properties
   EVOH compound film has high mechanical
strength, flexibility, surface strength, abrasive resistant,
weather resistance and strong antistatic capability. The material
has high gloss and the low fog density, so it has a high degree
of transparency.
