NOVA® KEY FACTS




1. POLAR-CO-MONOMER GRAFTED POLYOLEFIN
2. EXTRUDABLE
3. TIE RESIN
4. ADHERING TO BARRIER MATERIALS (ETHYLENE VINYL ALCOHOL (EVOH), POLYAMIDE (PA), METALS)

NOVA® 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. NOVA® 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.

Multilayer Structure with NOVA®


  • 1

    STRONG ADHESION

    By thermal reaction NOVA® adheres to ethylene vinyl alcohol (EVOH), polyamide (PA), polyester (PET), polyolefins (PE, PP) and metals.

  • 2

    ADHESION DURABILITY

    NOVA® shows excellent long-term adhesion strength even after secondary processing like pasteurization, hot filling, boiling and sterilization

  • 3

    POLYOLEFIN-LIKE PROPERTIES

    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.

  • 4

    EASY PROCESSING

    NOVA® , 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
    7. CO-INJECTION

Agriculture




MULCH FILMS

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:

VIF – VIRTUALLY IMPERMEABLE FILM:


  • 5 –LAYER STRUCTURE WITH PA

    significant improvement of gas retention; permeation is virtually blocked to keep fumigants in the soil

  • TIF – TOTALLY IMPERMEABLE FILM:

    7-LAYER STRUCTURE WITH EVOH

    significant improvement of gas retention; permeation is totally blocked to keep fumigants in the soil

  • MULCH FILMS – FEATURES:



    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
