The disclosure relates to a printed film including a base film, a removable printed layer containing an alkali-removable ink, and a finishing varnish layer, the layers being formed on the base film. The finishing varnish layer contains at least a curable resin and a curing agent, and the curing agent is blended in an amount of less than 40 parts by mass based on 100 parts by mass of the curable resin. Thus, the printed layer is prevented from being scratched or peeled off and can be reliably removed by alkali treatment at the time of disposal.

Printing film from which printing layer can be detached

Provided is a laminate that is excellent in heat sealing properties and is suitable for reuse. The laminate includes: a first layer having a melting point of Tmand containing a first polyethylene alone as a resin; and a second layer having a melting point of Tmand containing a second polyethylene alone as a resin, where: the first layer and the second layer are disposed respectively as outermost surfaces of the laminate; and Tm−Tm≥24.0° C. is satisfied.

Laminate, packaging bag, and method for manufacturing same

The present invention relates to an ornamental laminate film made from at least an inside film and an outside film, provided with a letter and/or a pattern by printing and as a raised part protruding toward the outside film. At least apart of the letter and/or the pattern has a metallic luster and differs in at least one of hue, brightness, chroma and glossiness from a region other than the letter and/or the pattern, and the raised part is formed along at least a part of the letter and/or the pattern. As a result of that, an ornamental laminate film with excellent design is provided without impairing its function as a packaging material.

Laminate film, and pouch-type container and sealing material having ornamental laminate film

To provide a pouch for achieving a reduced storage space with a simple configuration and a method for manufacturing the pouch. A pouch () including a gusset portion () includes a pouch main body () and an inner supporting member () disposed inside the pouch main body (). The pouch main body () includes a content containing portion () and a first fixture portion () and a second fixture portion () that face each other across the content containing portion (). The inner supporting member () includes a first fixing portion () fixed to the first fixture portion () and a second fixing portion () fixed to the second fixture portion ().

Pouch and pouch manufacturing method

A method for three-dimensionally forming a resin packaging member. The resin packaging member is heated to a temperature not higher than the Vicat softening temperature of the packaging member, and then compression shaping is conducted at a temperature not lower than room temperature and not higher than the Vicat softening temperature so as to form a three-dimensionally shaped portion with a large protrusion.
