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.
