A bag has a bag body that defines an interior and opening. A reclosable closure is configured for repeatably and nondestructively closing and opening the opening. A covering flap is connected to the bag body, extends away from the bag opening, and has a zone of weakness. The covering flap can be attached to the bag body while covering the closure. To access the closure, the covering flap is torn along its zone of weakness. The bag can also have a removable panel, which can be attached to the removable panels of other bags to form a header pack. The bag body and covering flap can be removed from the header pack by being torn along another zone of weakness between the covering flap and removable panel that has a lower tear strength that the zone of weakness of the covering flap.

The invention relates to a flat-lying side-gusset bag made of a plastic fabric composite (2) and to a method for the production thereof. The side-gusset bag has opposing front walls (3a, 3b), side gussets (4a, 4b) introduced in between said front walls (3a, 3b), and folding edges (5) between the front walls (3a, 3b) and the side gussets (4a, 4b). Peripheral sections of the plastic fabric composite (2) are connected together in an overlapping region (10) at a longitudinal seam, wherein the plastic fabric composite (2) has a plastic fabric (7) and at least one closed plastic layer. The side gussets (5) extend, in the case of the flat-lying side-gusset bag, in each case over at most ⅓ of the width of the front walls. According to the invention, the overlapping region (10) is arranged off-center on one of the front walls (3a, 3b) at least partially over one of the side gussets (4a, 4b) or at one of the side gussets (4a, 4b). In order to be able to form such a side-gusset bag, in the production method, first of all a closed, two-layer tube (12) is formed, from which a side-gusset tube (1) is subsequently formed.

A tamperproof bag includes a base, a pair of opposing end walls, and a pair of opposing sidewalls extending upwardly from the base to form an open upper end, defining an interior volume. Each end wall includes a height greater than a height of each sidewall, allowing for easier handling. An adhesive strip is disposed on an interior-facing surface of at least one end wall. The adhesive strip is configured to secure the end walls together to form a sealed closure and prevent access to the interior volume. Separation of the pair of end walls once adhered forms a tear in the bag, which may identify that an unauthorized access attempt to the bag has been made and prevents reclosure of the bag. A tab connected to a perforated strip that aligns with the adhesive strip provides a mechanism for accessing the interior of the bag.

The present disclosure is directed to provide a package which enables repeated opening and sealing of an opening, and can be favorably closed by bringing a pair of resin adhesive parts into contact with each other while preventing sticking of materials to each resin adhesive part. A package of the present disclosure comprises a main body having an internal space and an opening in communication between the internal space and an outside; and a pair of, i.e., two, resin adhesive parts which are disposed so as to be capable of being brought into contact with each other for sealing the opening. Here, the 90-degree peel force between the pair of resin adhesive parts is 0.02 N or more, the coefficient of dynamic friction of each of the two resin adhesive parts is 1.50 or less, and the tack force of each of the two resin adhesive parts is 1.60 N or less.

The present utility model refers to a bag or a bundle-type packaging suitable to contain cement or other similar material, consisting of at least one sheet of paper wherein the external sides of said sheets are coated with at least one layer of hydrophobic paint.

This paint transfers water-repellent characteristics to the paper; in this way, both the transmission of moisture/water vapor (WVTR) and the absorption of water (COBB) are significantly reduced.

In fact, thanks to at least one layer of paint applied externally to the sheets of paper that make up the bag, the water is not retained by the paper, but slips away due to the high surface tension present on the treated paper.

The barrier effect is thus increased compared to that obtainable from standard bags known in the art, thus guaranteeing the product contained inside the bag a high protection from humidity, even in the absence of intermediate polythene sheets in the manufacture of the bag and, consequently, improving the shelf life of the product contained inside the bag.

The bag achieves these results even though it has no intermediate plastic layers.
