A machine for providing cushioning products of varying lengths from a supply of a web material having sequential transverse rows of inflated protrusions. A pair of opposing feed members form a feed nip for moving the web along a path of travel. At least one sensor detects location information for the sequential rows of inflated protrusions as the web travels along the path of travel. A severing device is moveable between (i) an engaged position to separate the web transversely or perforate the web transversely and (ii) a disengaged position. A controller is programmed (i) to receive the location information and (ii) to operatively control the severing device to move it to the engaged position when a selected row is in a determined position relative the severing device.

An intermediate product (1) for producing a preferably sleeve- or bag-shaped packing means at least partially made of film material comprises a film material extending along a first portion (1a) and a second portion (1b) of the intermediate product, the film material being provided with a tearing line (53) for separating the first portion and the second portion from each other, wherein the first portion, once separated from the second portion, forms the packing means, and the second portion, while connected to the first portion, forms a part to be attached to a carrier for carrying the intermediate product. The film material is provided with a layer of added material (50) extending along the tearing line.

A method of making a storage bag (10) comprising the following steps performed in any order: (a) forming a composite tube having an inner surface comprising a higher melting polymer, an outer surface comprising a lower melting polymer, two ends (14a, 14b), and a diameter; (b) flattening the tube in a direction perpendicular to the diameter; (c) forming a joint (15) at one of the ends at a temperature between respective melting points of the higher melting polymer and the lower melting polymer; (d) providing a composite sheet (20) having a first side comprising a higher melting polymer and a second side comprising a lower melting polymer; and (e) disposing the composite sheet (20) over the joint (15) such that the first side comprising a lower melting polymer engages the joint (15) and forming a lap seam over the joint at a temperature between respective melting points of the higher melting polymer and the lower melting polymer, and a storage bag (10) made by such method.
摘要:
The method serves for producing flexible packaging products, more particularly packaging bags, the packaging products being formed by welding together two film layers. In order to avoid imprecisions in the sequence of process steps, film sections (4) formed of film layers are separated from a film web (7a; 7b) and transferred to a transport device (1) where they are positively fixed at least at one edge by means of a fixing device (3). Then the film sections (4) are transported by means of the transport device (1) in a transport direction (5) to at least one welding station (12) while maintaining the positive fit, the film layers are welded together in the latter, and the film sections (4) are subsequently further transported while maintaining the positive fit.
摘要:
A reusable closure system is disclosed for flexible packaging applications. The system generally includes base and lid portions. The base portion (109) can be bonded to underlying package material and includes first and second fields of touch fasteners (111) separated by a multi-layer buffer zone (113). The buffer zone can be at least in part co-located with a frangible region of underlying package material. In some embodiments, the buffer zone is substantially free of active bonding agent, such that there is little or no active bonding agent overlapping the frangible region. One of the touch fastener fields of the base can be deployed at least partially within the area defined by the frangible region (102). The other touch fastener field is deployed around the buffer zone. The lid portion can be bonded to the package material and/or base portion, and includes a hinge and another touch fastener field to mate with the base fields.
摘要:

Die zweite Schicht umfasst ein faserhaltiges Material.
摘要:
Methods for creating multi-layered bags with increased or maintained strength involve forming a ribbed pattern in one or more film layers of a multi-layered bag. The method also includes non-continuously laminating the film layers of the multi- layered bag together. In one or more implementation, a transverse direction ring rolling process forms the ribbed pattern and bonds the film layers together. In one or more additional implementations, the ribbed pattern and lamination are formed separately. Still further implementations include forming network patterns one or more film layers of a multi-layered bag. Multi-layered bags formed in accordance with one or more implementations of the present invention include one or more of increased strength or reduced basis weight.
