Also, the adhesive coating module is configured to apply an adhesive to an outermost surface of the embossed one or more first layers and an inner surface of the second layer.

Method Of Manufacturing A Paper Bag For Containing Sanitary Products
20230347614 · 2023-11-02 ·

A method of making a paper bag for containing sanitary products, which includes conveying a paper web having a first side and a second side in a conveying direction; Applying a sealable coating to the first side of the paper web in sections, and applying second coating strips extending substantially transversely to the conveying direction and spaced apart from one another in the conveying direction; folding onto itself the first side of the paper web along the direction of conveyance to form a two-ply web having a folding configuration; and heat sealing the second coating strips to form side seams each defining a bag interior; separating the two-ply web along the heat sealed side seams to separate the two-ply web into individual paper bags.

Flexible packaging structure with a built-in opening and reclose feature

A flexible packaging laminate is formed to have a built-in opening and reclose feature by forming the laminate as a two-part structure having an outer structure joined in face-to-face relation with an inner structure. Score lines are formed in both structures to enable an opening to be formed through the laminate by lifting an opening portion (e.g., a flap or the like) of the two structures out of the plane of the laminate. The score line through the outer structure defines a larger opening than the score line through the inner structure, such that a marginal region of the outer structure extends beyond the edge of the opening portion of the inner structure. A pressure-sensitive adhesive is used to re-adhere the marginal region to an underlying surface of the inner structure adjacent the opening through the laminate.

REINFORCED THERMOPLASTIC BAG WITH EXTENDED HEM SKIRT
20220219865 · 2022-07-14 ·

The present disclosure relates to strata 2-ply drawstring trash bags implementing a J-flap extended hem to provide increased top-of-bag strength. In one or more embodiments, the J-flap extended hem includes a 2-ply web folded back on itself (e.g., during a hem folding operation to enclose the drawstring within a hem channel). In one or more implementations, a hem seal secures the 2-ply web to an inside surface of the trash bag. At least one ply of the 2-ply web fold-over extends past the hem seal and is additionally secured to the inside surface of the trash bag via one or more hem skirt seals. For reduced material consumption in certain embodiments, the J-flap extended hem of the present disclosure imparts added strength using only one ply of the 2-ply web fold-over. In some embodiments, at least one ply of the 2-ply web fold-over includes ring-rolled portions to add top-of-bag strength.

THERMOPLASTIC FILMS AND BAGS WITH ENCAPSULATION-BASED DELAYED ODOR CONTROL AND METHODS OF MAKING THE SAME

The present disclosure relates to a thermoplastic film that includes a plurality of ribs and a plurality of web areas that separate and connect the ribs. The thermoplastic film further includes an encapsulated odor control component that includes an odor control active encapsulated within a plurality of encapsulants. The encapsulants can be configured to delay a release of the odor-control active until activated. Further, the encapsulated odor control component can be applied across the plurality of ribs and the plurality of web areas, which can be configured to cause the encapsulants to activate in phases.

ADDITIVE APPLICATION SYSTEMS AND METHODS FOR PADDED MAILERS

An additive application system utilized to form a padded mailer is provided, along with corresponding methods and systems. The system applies an additive liquid to a portion of a first web that, along with a second web, forms a panel of the padded mailer. After contact occurs, an internal pouch for the panel is formed. When the additive liquid and expandable adhesive positioned within the internal pouch are energized via an oven, the expandable adhesive expands in thickness within the internal pouch to form padding for the panel. Utilizing additive liquid enables use of less expandable adhesive while maintaining a desired speed of operation of the oven to still produce a desired thickness for the padding. Cooling may be applied after expansion in the oven to retain thickness expansion in the padding.
