HEAT SEALABLE MONOAXIALLY ORIENTED PROPYLENE-BASED FILM WITH DIRECTIONAL TEAR. |
摘要 |
A monoaxially oriented film including an ethylene-propylene impact copolymer and 3-15 wt% of a metallocene-catalyzed propyl ene-butene elastomer and 30-60 wt% of a crystalline propylene homopolymer which is oriented at least 3 times in the machine direction and exhibits excellent linear directional tear properties in the machine direction for retort pouch applications and has excellent heat seal performance both pre- and post-retorting. This film formulation and orientation is suitable for pouch applications requiring an "easy-tear" linear tear feature and excellent hermetic seal properties, particularly for retort pouches. |
