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 the 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.
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.
