resins are modified polyolefins with functional groups, designed to bond to a variety of
polyolefins, ionomers, polyamides, ethylene vinyl alcohol (EVOH), polyester (e.g. PET) and
metals. They serve as tie layer in multilayer applications such as films, sheets, bottles, tanks,
pipes, tubes and others and, thus, help to combine the excellent properties of incompatible
materials, as, for example, gas barrier resins and moisture barrier resins.
resins are also used as coupling agents, compatibilizers and impact modifiers in various
types of composites. NOVA®
adhesives are thermoplastics and can be as easily processed as any
other polyolefin by (co-)extrusion or powder coating. NOVA®
is famous for its excellent quality
and is therefore the world’s leading polyolefin-based adhesive. Production sites all over the world
assure a constant and convenient availability of our top quality adhesives.
By thermal reaction NOVA® adheres to ethylene vinyl alcohol (EVOH), polyamide (PA), polyester (PET), polyolefins (PE, PP) and metals.
NOVA® shows excellent long-term adhesion strength even after secondary processing like pasteurization, hot filling, boiling and sterilization
Since NOVA® is based on polyolefins or copolymers, it retains the physical properties of each polyolefin or co-polymer including mechanical strength, heat resistance, chemical resistance and recyclability.
, a thermoplastic, can be processed as easily
as any other polyolefin by the following methods:
1. FILM CO-EXTRUSION (CAST AND BLOWN FILM)
2. CO-EXTRUSION BLOW MOULDING
3. SHEET CO-EXTRUSION
4. TUBE CO-EXTRUSION
5. CO-EXTRUSION COATING
6. METAL COATING
The use of fumigant gases, like pesticides and fungicides, is widely spread in agriculture to ensure
growth of high quality vegetables, fruits or flowers. Co-extruded multilayer mulch films are
designed for keeping these ozone depleting gases in the soil and for assuring better crop growth by
suppressing weeds, reducing water evaporation and creating optimized conditions which stabilize
or extend the growing season. Besides this, mulch films provide maximum tear resistance and
optimized on-field duration.
As, however, fumigant gases may cause health risks to field workers and residents, the fumigation
process needs to be optimized to minimize human and environmental damage. To keep the harmful
gases in the soil and to reduce the emission rates, high-barrier films are designed:
significant improvement of gas retention; permeation is virtually blocked to keep fumigants in the soil
significant improvement of gas retention; permeation is totally blocked to keep fumigants in the soil
1. improved gas retention due to virtually/totally blocked
permeation; fumigation gases are kept in the soil
2. Water conservation
3. tear resistance
4. on-field duration
