NON-METALLIC TIE
A non-metallic tie, for example a twist-tie or a tin-tie, comprises a polymeric material melt-blending from a composition containing (a) from about 50 to about 80 wt % of at least one matrix-forming thermoplastic polymer which is amorphous or becomes amorphous when melted, and (b) from about 20 to about 50 wt % of at least one elastomeric polymer which has a flexural modulus of less than 700 MPa and a glass transition temperature less than 25 C., based on the combined weight of (a) and (b). The tie is characterized by tensile elongation at break according to ASTM D638-00 of from about 20 to about 100; and a dead fold angle equal to or less than about 30, as determined by a method including the steps of (i) providing a sample of the twist tie having two end portions, a thickness of 1-2 mm and a length of about 100 mm; (ii) folding the sample approximately in half in the lengthwise direction so that end portions are approximately adjacent to each other; (iii) relaxing the folded sample at room temperature for three minutes; and (iv) measuring as the dead fold angle the included angle between the article sample end portions.
Convertible Bag
A bag includes a first sidewall, a second opposing sidewall, and a foldable base. The foldable base is coupled to the first sidewall and the second side wall. The foldable base includes a first rigid panel coupled to a second rigid panel such that the foldable base is configured to fold from a generally flat configuration to a folded configuration, thereby converting the bag from an expanded configuration to a collapsed configuration.
RESEALABLE BAG WITH CUTTING MECHANISM
A sealing and cutting assembly for engaging a bag to cut and reseal the bag comprises a first sealing strip and a second sealing strip connected at corresponding ends thereof and engaging both sides the bag therebetween. A slider block is movable along the first sealing strip and the second sealing strip. Movement of the slider block in a first direction bringing the first sealing strip and the second sealing strip into sealing engagement with one another to seal the bag, and movement of the slider block in a second direction releasing the first sealing strip and the second sealing strip from said sealing engagement to open the bag. A cutting mechanism mounted on the slider block, wherein the cutting mechanism moves with the slider block along the first sealing strip and the second sealing strip.
Package with Peelable and Non-Peelable Heat Seals
A package, e.g., a pouch, comprising: (A) An exterior surface comprising oriented-polypropylene (OPP), and (B) An interior surface comprising a blend, in weight percent based on the weight of the blend, of: (1) From 30 to 80 wt % of a propylene-based plastomer or elastomer (PBPE), and (2) From 20 to 70 wt % of low density polyethylene (LDPE); the package further comprising (C) A peelable end seal formed by joining in a heat seal two sections of the interior surface, the heat seal having a seal strength of 1 to 4 pounds per inch (1b/in) (4.48 to 17.9 Newton (N)/25.4 millimeter (mm)), and (D) A lap seal formed by joining in a heat seal a section of the interior surface with a section of the exterior surface, the heat seal having a seal strength of greater than or equal to () 15 lb/in (67.2 N/25.4 mm).
Resealable package method for producing the resealable package and apparatus for producing the resealable package
The invention relates to a resealable package (1, 1, 1), comprising a package body (2) having a first side wall (4), a second side wall (6) opposite the first side wall (4), an openable top end (8) and a closed bottom end (10), wherein a portion (12) of the first side wall (4) protrudes beyond the second side wall (6) at the top end (8) in a direction from the bottom end (10) to the top end (8), and a closure element (18) which is releasably adhered to an inner surface (14) of the portion (12) of the first side wall (4) which protrudes beyond the second side wall (6) and the second side wall (6) so as to close the top end (8), Upon removal of the closure element (18) from the package body (2), a resealable adhesive arrangement (20, 22; 23; 25) is exposed so as to allow the inner surface (14) of the portion (12) of the first side wall (4) which protrudes beyond the second side wall (6) and an outer surface (16) of the second side wall (6) to be resealably adhered to one another in a position to close the top end (8). Further, the invention relates to a method and an apparatus (100) for producing the resealable package (1, 1, 1).
Self-closing sack
A sack includes a flexible sack body and a mouth that includes two separable lips that form a mouth opening when the lips are separated from one another, and that close the opening when the lips are adjacent to one another. Closing structure is configured to enable a separating force that is applied to the lips to separate the lips from one another to form the mouth opening, and to bring the lips adjacent to one another to close the mouth opening in the absence of the applied separating force.
CLOSURE ASSEMBLY FOR A BAG AND A METHOD OF CLOSING THE BAG
A closure assembly for a bag, comprises, a first closure having a first longitudinal member, the first longitudinal member having a first end and a second end, the longitudinal member being provided with a clamping arrangement adapted to clamp a bag, the clamping arrangement comprising a first clamp at the first end and a second clamp at the second end, wherein, a bottom surface of the longitudinal member comprises two edges adapted to be separated under force and snap into a closed position elastically, wherein the first clamp and the second clamp are adapted to limit the separation between the two edges and a second closure having a second longitudinal member, the second longitudinal member having a hollow cross section defining a cavity adapted to receive the first closure.
Resealable bag with cutting mechanism
A combination sealing and cutting assembly for a bag comprises a first sealing strip and a second sealing strip. The first sealing strip and second sealing strip are connected at their corresponding ends. A slider block is movable along the first sealing strip and the second sealing strip. Movement of the slider block in a first direction brings the first sealing strip and the second sealing strip into sealing engagement with one another while movement of the slider block in a second direction releases the first sealing strip and the second sealing from said sealing engagement. A cutting mechanism is mounted on the slider block and moves with the slider block along the first sealing strip and the second sealing strip.
FLEXIBLE SEALING STRIP
A flexible sealing strip applied to a long soft opening of an airtight or watertight bag is revealed. The flexible sealing strip includes a long cut portion, a first plate portion and a second plate portion formed integrally on two sides of the long cut portion in a length direction respectively, and a fastening portion arranged at two ends thereof. The long soft opening is opened when the first and the second plate portions are bent flexibly and away from each other relative to the long cut portion. The long soft opening is closed when the first and the second plate portions are turned back to the original state, parallel to each other in the length direction. Next the flexible sealing strip is rotated 360 degrees relative to the long soft opening and bent so that the fastening portion is secured. Therefore the bag is sealed firmly.
CLOSURE SYSTEM FOR FLEXIBLE BAG
The present disclosure relates to a closure system for a flexible container. The closure system generally includes a flexible member and a substantially rigid member. The flexible and rigid members are each interconnected to opposing portions of an aperture of the container. When the closure system is in a closed state, the flexible member is in a position proximate to the rigid member. The flexible member may be pulled away from the rigid member to move the closure system to an open state. The closure system will remain in the open or closed state without contact from the user. The user may return the closure system to the closed state by applying a predetermined force to the flexible member.
