    1. Copolymer is 1-butene based polymer. It is compatible with PE and PP, offering unique functions in both PE and PP based products

    2. Copolymer is dispersed in PE with domain size of a few microns, which ensures stability of easy-peel property. Heat seal strength of film can be easily controlled.

    3. Copolymer is also utilized as a modifier to improve low temperature heat sealability of PP films due to its compatibility and low melting point.

    ADVANCED MATERIALS

    ■ Wood Fiber-Excellent filler loading property

    - WF/PB-1

    Surface improvement - High dispersion and burning (fiber-degradation) prevention compared to other resins

    - PB-1 durability

    (1) Low temperature process - Surface improvement, WF burning odor reduction (Spiral test confirmation)
    (2) Improvement of fluidity and dispersion
    (3) Reduction of extrusion pressure, increase of WF content
