[Problem] Transparency, tear strength, rigidity and impact strength are well balanced, low-temperature heat sealability and rigidity are well balanced, good hot tack strength when heat-sealed with low sound, and heat-sealed when high temperature. Resin composition and film having both good hot-tack strength United States Patent Application 20060128400 Kind Code: A1 99 to 50% by weight of an ethylene copolymer (component A) produced using a metallocene catalyst, and a propylene copolymer (component B) ) Resin composition containing 50 to 1% by weight [Effect] Since the resin composition has excellent hot tack strength in both the low-temperature region and the high-temperature region, the vertical pillow packaging can be stably performed. For example, when the sealing temperature is 90 ° C. (low temperature range) and 120 ° C. (high temperature range), a hot tack strength of 1.5 N or more and a heat seal strength of 1200 g / 15 mm or more can be achieved. [Selection diagram] None |
