The present invention is directed to a method of incrementally stretching polymeric film formed from a blown film extrusion process. The present invention is further directed to a polymeric bag formed from an incrementally stretched polymeric film. The incremental stretching is performed on a collapsed polymeric bubble via a pair of intermeshing rollers. The incrementally stretched polymeric film may be stretched only along a portion of its width. The polymeric bag may be a drawstring trash bag with an extended hem where only the extended hem of the bag or the body of the bag comprises incrementally stretched polymeric film.

A breathable bag (1) especially suitable for packaging horticultural products (2) comprising a mesh casing (3), which is capable of housing the products to be packaged and at least one first band (5) of flexible material applied on the outside of and joined to the casing by affixed areas (6, 7) affixed to said casing, the first band covering a region (8) of the casing that has a hole (9), the practical access to the hole (9) being prevented by the affixed joining areas (6, 7) between the first band (5) and the casing (3), and the first band (5) being equipped with at least one tear line (10) that determines in the first band (5) a removable portion (5c) from the casing (3) that is sufficient to leave uncovered or to open a practical access to said opening (9).

A pouch or pocket may act as a container and may be used to securely hold objects (e.g., cell phone, keys, wallet, etc.) during athletic activity (e.g., running). The pouch may be a standalone item or integrally formed as part of other items. The pouch may hold the object to be stored in place within the pouch or pocket. The pouch may provide some cushioning or impact force attenuation to protect the object being held within the pouch or pocket. Additionally, the pouch may be attached to a garment, such as running clothes. The pouch includes an outer envelope sealable by a closure and a one-way valve with foam layers located inside the pouch. After the object is placed in the pouch, the closure is closed, and the air within the pouch is expelled via the one-way valve by compressing the foam layers from the outside.

A device and a method for applying cover sheets to cross-bottoms of tubular sections made of a plastic material. The device includes conveyor devices for transporting the tubular sections and for depositing the cover sheets on the cross-bottoms in a deposit area. The device includes a hot gas device with a gas heater and a nozzle connected to the gas heater and oriented toward the deposit area for the cover sheets so when gas is supplied to the gas heater, the gas flows along a flow path from the gas supply through the gas heater and the nozzle into the deposit area. The hot gas device has a hot gas reservoir with an internal volume for the temporary storage of hot gas, the flow path running through the hot gas reservoir. A gas mass flow ({dot over (m)}1, {dot over (m)}2, {dot over (m)}ges) of gas supplied to the gas heater is adjustable by a control.

The present invention is a bag making machine (20, 30). The bag making machine (20, 30) includes: a conveying unit (37) which conveys a multi-layer film (S) in which films (13a, 13b) are overlapped; a side edge sealing device (27) which thermally fuses the films (13a, 13b) to each other; and an ultrasonic device (26) which crushes a part of a zipper member (14) disposed between films (13a, 13b). The side edge sealing device (27) includes: a platform (44); and a heat-generating head (45). The ultrasonic device (26) includes: an anvil (41); and an ultrasonic horn head (42). The heating-generating head (45) and the ultrasonic horn head (42) reciprocate at a same cycle via a link member (51).

An envelope liner template having a first panel having a pattern inscribed therein and a second panel. The second panel is positioned below the first template and attached by a fastening mechanism. The fastening mechanism is adapted to secure a decorative sheet in place between the first panel and the second panel when a cutting implement cuts through the pattern and the sheet against the second template panel to form an envelope liner.
