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.

Liners for cooking vessels, cooking systems, and methods of making liners for cooking vessels are disclosed. The liner can be a multi-layer liner having a bag-like structure with a closed bottom having a bottom edge, a top opening having first and second top edges, and two sealed sides. The liner can have a first side seal extending along a first end from the top opening toward the bottom edge and a second side seal extending along a second end from the top opening toward the bottom edge. The liner material can include an aluminum foil sheet thermally laminated to a polymer film. The polymer film can include a biaxially-oriented polyethylene terephthalate layer coextruded with an amorphous polyethylene terephthalate sealant layer.

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.
摘要:
The invention relates to a packaging means, especially a sack-shaped packaging means, comprising a packaging material (101) which is arranged in at least two layers, wherein the packaging material has at least two layers (A, I). According to the invention, a first layer comprises a non-woven fabric (103) and a second layer, which is connected in at least some areas to the non-woven fabric, comprises a plastic (102). The plastic used is at least one monoaxially or biaxially stretched film web (102).
摘要:
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:
A method for providing crease lines (9) to a packaging material (2) having a bulk layer is provided. The method comprises the steps of arranging the material (2) to be creased between an elastic anvil (14) and a pressing tool (12) having at least one protrusive ridge (20) facing the anvil (14), and pressing the ridge (20) towards the anvil (14) such that the packaging material (2) will be subject to an imprint, whereby the width of the imprint is continuously increasing as the ridge (20) is pressed against the anvil (14).
摘要:
Die Erfindung beschreibt ein Packmittel, insbesondere sackförmiges Packmittel, welches einen Packstoff umfasst, der zumindest zweilagig angeordnet ist, wobei der Packstoff zumindest zwei Schichten umfasst, wobei eine erste Schicht Vliesstoff umfasst. 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.
