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
