摘要： An object of the present invention is to provide a laser-printable laminate display body in which printing is not peeled off even when an external stimulus such as rubbing is applied, and to provide a laminate display body which can afford high-quality laser printing such that characters can be clearly visually recognized by high density and fineness of printing and does not cause defects such as perforation due to laser printing. A laminate display body including at least one printing layer that can undergo printing by laser irradiation, in which the laser printing layer includes a laser-printed portion printed by laser and a non-printed portion, at least one laser non-absorbing layer is laminated on the printing layer, and the absolute value of the difference in color L* value between the laser-printed portion and the non-printed portion is 1.0 or more and 10.0 or less.

摘要： Provided is a multilayer body having favorable thermal dimensional stability and capable of producing a food-packaging bag where without providing any perforations or guiding lines through laser half cutting, a resistance at opening by tearing is low, and only a small extent of parting occurs; and a step is formed between opening ends on the front and back sides to be easily opened and contents can easily be taken out therefrom. A multilayer body having one or more types of base material films; and a polyolefin-based resin sealant film made from a polyolefin-based resin composition containing a propylene-α-olefin random copolymer, wherein 1) the base material films have orientation angles, a sum of absolute values of which is 25° to 85°, 2) the sealant film has a piercing strength of 5.0 to 15.0 N, and 3) the sealant film has an orientation coefficient ΔNx, in a longitudinal direction, of 0.0150 to 0.0230.

摘要： Disclosed are a propylene polymer-based composite film, a preparation method therefor, and an application thereof. The composite film comprises at least two different layers: layer a and layer b, wherein layer a and layer b each comprise at least one propylene polymer, and at least one of layer a and layer b comprises a propylene impact copolymer, wherein the propylene impact copolymer comprises elastic moieties that form dispersed strip-like rubber phases in the composite film, the rubber phases are arranged parallel to each other, and the average dimension of transverse axes of the rubber phases is 20-200 nm and the average of aspect ratios is 5-20. The composite film has both excellent impact resistance and optical properties, and even has good tensile properties and/or good heat-sealing strength at lower heat-sealing temperatures, and even has good uniformity. The composite film is particularly useful in the field of packaging materials, especially in battery packaging materials, electronic product packaging materials, or food packaging materials.
