To find a combination of a laminate packing material and a liquid composition containing a methoxycinnamic acid ester compound as a translucent or white-turbid emulsified product in an aquatic component, so that the composition will not change if it is accommodated in the packing material, as well as to provide a laminate packing type product which can maintain its quality over time equivalent to a product accommodated in a glass bottle.

The laminate packaging type product is formed by accommodating the liquid composition, a translucent or white-turbid oil-in-water emulsion, which contains components (A) to (C): (A) a methoxycinnamic acid ester compound, (B) phosphate ester anionic surface-active agent, and (C) water, in the packaging bag formed with a laminate film having a sealant layer containing a resin which includes a cyclic polyolefin resin as a primary component.
