Definitions
- the present invention relates to a propylene-based resin and a propylene-based polymer composition, and a film and a laminate comprising the same.
- a propylene-based polymer and propylene-based polymer composition with excellent low-temperature heat-sealing properties, a highly balanced rigidity and heat-sealing properties that have never been seen before, and improved antiblocking properties, slip properties, and moldability.
- the present invention relates to articles and films or food packaging films, laminates, fibers, sheets and molded articles made of them. Background art
- Polypropylene has been used in a wide variety of applications as a general-purpose resin because of its toughness, excellent heat resistance, and low cost.
- Crystalline propylene-based polymer films are widely used as packaging films because of their excellent rigidity, transparency and moisture-proof properties. Normally, these films are made by heat sealing, and after filling the contents, the bag mouth is closed again by heat sealing.
- the resin film used as the outermost layer of this multilayer film has the low-temperature heat-sealing properties required to speed up the above series of bag-making and packaging processes, and the slip properties required to perform the film rewinding process without hindrance. It is particularly required to exhibit excellent performance in terms of anti-locking and anti-locking properties.
- Propylene polymers require a higher degree of supercooling to initiate crystallization than ethylene polymers and have lower crystallization temperatures (T c) even at the same melting point (T m). This is particularly noticeable in low crystallinity polymers such as copolymers and polymers with low stereoregularity. This makes molding difficult and reduces resin properties, especially transparency, heat seal temperature (HST), modulus of elasticity, and impact resistance.
- HST heat seal temperature
- molding defects, especially chill roll release defects are likely to occur, and only the film becomes unstable. There is a problem that a sweeper roll mark is easily formed. Therefore, it was necessary to solve this problem in order to obtain films, fibers, sheets, and molded articles having excellent low-temperature heat sealability.
- the propylene-based polymer obtained by the conventional so-called Ziegler catalyst system has a wide molecular weight distribution and composition distribution, and is non-uniform, so that the high crystalline components contained in it generate rapid crystal nuclei, The degree of supercooling required for the onset of formation did not become relatively large, and the formability did not decrease so much.
- the non-uniformity of the composition due to the non-uniformity of the composition, the physical properties are reduced, and the resin composition contains sticky components and highly crystalline components, so that it has not yet reached the original resin physical properties.
- Polypropylene polymerized using a meta-opening catalyst developed in recent years is a single-site catalyst, so its composition is uniform, and there are few components that cause deterioration in physical properties such as sticky components and highly crystalline components. Excellent physical properties compared to conventional catalysts. However, the degree of supercooling was increased due to the uniformity of the composition, and the moldability was significantly deteriorated.
- a method has been proposed in which a propylene-based polymer polymerized with a meta-aqueous catalyst is used as a heat seal improver with a conventional propylene-based polymer polymerized with a Ziegler catalyst. (Japanese Unexamined Patent Publication Nos. Hei 2-173016, Hei 5-112628, and Hei 5_112883). However, although there was some improvement in the balance between heat sealability and film rigidity, there was still a problem in the balance between moldability and physical properties.
- the present invention achieves a further improvement in heat sealability to an extent comparable to that of linear low-density polyethylene without impairing the preferable properties inherent in the polypropylene film.
- anti-locking properties, film rigidity and film impact characteristics are maintained at a high level, and a balanced propylene-based polymer and propylene-based polymer composition, and a film or food packaging film, fiber, sheet, It is intended to provide various molded articles such as nonwoven fabrics.
- a propylene polymer having a uniform composition obtained with a metallocene catalyst can be rapidly produced in a molten propylene polymer without deteriorating the physical properties of the propylene polymer.
