Market-Machinery-Applications
Synopsis : Oriented films are known to have improved properties
in comparison to non-oriented films.
Presently the production of oriented film is sub-divided into the
following material groups:
 |
OPP - 58.3% |
 |
OPET - 29.6% |
 |
OPS - 7.5% |
 |
OPVC - 1.4% |
 |
OPA - 1.8% |
 |
Rest - 1.4% |
The share of OPE is so small that it appears under the category
'Rest' of the above table.
The PE market in North America is presently
 |
Films for general packaging (Consumer goods, carrier bags etc.)
- 35% |
 |
Films for food packaging - 42% |
 |
Films for industrial packaging - 23% |
The raw material manufacturers seem to have identified a potential
for oriented PE films and offer blown film resins which after orienting
have the same optical properties as OPP and partially even better
stiffness and tensile strength. Monoaxial oriented lines are now
offered by Hosokawa Alpine AG & Co., OHG to produce OPE films. The
orienting process increases strength in machine direction, provides
stiffness and barrier properties and has increased transmittance.
Bread to bakery products are candidates for OPE films as are also
snack foods. New developments on the raw material side, together
with improved machinery technologies are able to meet the demand
and offer cost saving production of film with improved optical and
mechanical properties.
