Non-durable self-supporting flexible containers.

A trifold side seamed film produce bag includes a front wall and a back wall, first and second side edges sealed together and a seamless bag bottom. The bag is joined at the side edges to additional bags by a perforation. The bag is corona treated on at least one wall and promotional material is printed on the treated surface. The bags are folded to one third of their height to fit compact bag roll dispensers. The bags are folded in a Z-fold or C-fold configuration. The method includes manufacturing the bags and winding them onto cores or forming the bags into coreless rolls. An apparatus for forming the side seamed bags includes an extruder, a tubing flattener, a perforator, a sealer, a corona treater, a printer and a slitter. The treated, printed bags may be stored on rolls for later slitting into two bag streams and folding into thirds.

Disclosed herein are adapters for use with ordinary lawn and leaf bags. In one example, a foldable, expandable, and reusable adapter is provided. The adapter includes a rectangular base unit that is designed to receive four connector pieces. The four connector pieces are made of a rigid material and may include respective vertical and horizontal creases that allow them to be folded. As such, once assembled, the adapter may be folded for storage and later expanded for use. In use, the adapter is inserted into a lawn or leaf bag and provides a larger opening for the bag as well as prevents the mouth of the bag from closing.

A flexible material for a flexible container can include a first laminate and a second laminate joined to at least a portion of the first laminate by at least one seal. The first laminate can include a first gas barrier layer disposed between first and second sealable layers, wherein the first and second sealable layers define opposed exterior layers of the first laminate. The second laminate can include a third sealable layer defining an exterior layer of the second laminate, and a second gas barrier layer. The at least one seal joins a portion of the third sealable layer to at least a portion of the second sealable layer.

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.

An example tote package is disclosed for carrying a load external to a UAV. The tote package may be generated by folding a sheet of material. The sheet may include a middle section, a first side section, and a second side section. When the sheet is folded, the middle section may create a bottom portion of the tote package. Additionally, the first side section may create a first side portion tapering up from the edge of the bottom portion to the middle of the top portion of the tote package. Furthermore, the second side section may create a second side portion tapering up from the opposite edge to the middle of the top portion. At the top portion, the first and second sections may connect to create a handle. The first side, second side, and middle sections may be folded to create front and back portions of the tote package.

A preservative composition includes a source of ascorbate or erythorbate ions, or a mixture thereof, a source of calcium ions and one or more food grade sequestrants, wherein the molar ratio of ascorbate or erythorbate ions, or a mixture thereof, to calcium ions is of from 0.5:1 to 1.4:1.

The disclosure is directed to sampling bags having flexible walls. The sampling bags may have agile walls that include a shape memory component. The shape memory component tends to return the sampling bag to its initial shape. Such sampling bags may be used in a variety of sampling methods.
