摘要:
A packaging member (1, 80, 100) is provided with easy-opening means (7, 85, 107, 108) for allowing the packaging member to be opened easily, wherein the easy-opening means is either positionally 5 or structurally improved. As one example, the packaging member is a packaging bag (1, 80), in which the easy-opening means serves as a tearing start point when opened with the use of the easy-opening means. The easy-opening portion is formed at a position slightly shifted inward from a perimeter edge of the 10 packaging bag. As another example, the packaging member is a packaging container (100), in which the easy-opening means is structurally improved.

A packaging material capable of having a desired sealing strength with ease and a packaging bag using such material are provided. A packaging material (1), which serves as either one of a first and a second packaging materials (1, 1A) to be heat-sealed to each other, includes a sealing portion (2). This sealing portion is weaker in sealing strength than other portions and composed of an applied area (3) of a coating agent preventing the heat sealing and a non-applied area (4) of the coating agent. The applied area and the non-applied area are easily changed in an area size from each other depending on the sealing strength required for the sealing portion.

A gusset bag (10) is formed of a pair of flat surface parts (12A and 12B) facing each other, and side gusset parts (14) folded to the inside of the bag. The gusset bag (10) has side heat-sealing portions (16A) at which the sides of the flat surface part (12A) and sides of the side gusset parts (14) are joined at the inner surfaces thereof, side heat-sealing portions (16B) at which the sides of the flat surface part (12B) and the other sides of the side gusset parts (14) are joined at the inner surfaces thereof, and closing sealing portions (18) at which the side heat-sealing portions (16A) and the side heat-sealing portions (16B) are joined at the outer surfaces of the side gusset parts (14) by ultrasonic sealing. With this configuration, in the gusset bag (10), it is possible to easily close the gusset parts, while preventing film pieces or dust from entering the bag in a step of closing the gusset parts.

The method for attaching a thin cylindrical element (4) to a mold core (3) is a method for attaching a film-like thin cylindrical element (4), which is formed in a cylindrical shape having a constant cross-sectional shape, to an outer surface of a mold core (3) in a manner so as to cover the mold core (3). The method includes pressing the thin cylindrical element (4) onto a tip portion (3A) of the mold core (3); guiding the thin cylindrical element (4) to the base end side of the mold core (3) while ejecting gas into between the mold core (3) and the thin cylindrical element (4); and attaching the thin cylindrical element (4) to the outer surface of the mold core (3) in a manner so as to cover the mold core (3).
摘要:
[Problem] It is to provide a polyethylene sealant film having a great strength and good heat sealability even though being thin. [Solving Means] The above problem is solved by the multilayer polyethylene sealant film produced by the method of producing a multilayer polyethylene sealant film comprising coextruding and stretching a sealant layer comprising a low density polyethylene resin or linear low density polyethylene resin and an orientation layer comprising a polyethylene resin having a melting point higher than the sealant layer by an inflation method at a temperature higher than the melting point of the sealant layer and higher than the Vicat softening temperature but lower than the melting point of the orientation layer.
