A flexible container incorporating flexible front and rear sheets with a perimeter seal in which at least one length or section of the perimeter seal can include a seal weld that has both a permanent seal section and a pressure absorbing seal section. The pressure absorbing seal section is configured to peel, fail, or split when the flexible container, filled with a solution or liquid, is dropped onto a hard surface to thereby absorb the impact of the drop. The flexible container can be provided with one or more dispensing and/or additive ports or without any port. The flexible container may include more than one compartments with a peelable seal separating two adjoining compartments of the flexible container.

A method for inspecting a joining surface (14) of a substrate, wherein a component is to be adhered to the joining surface of the substrate by means of an adhesive material (27), wherein the method comprises the following steps: providing at least one planar test textile (20), which has a fiber material (21) and an adhesive primer (22), applying the planar test textile to at least one part of the joining surface of the substrate to which the component is to be adhered so that the adhesive primer of the planar test textile contacts the joining surface of the substrate, at least partially curing the adhesive primer of the planar test textile in order to integrally bond the planar test textile to the substrate by means of the adhesive primer, pulling off the planar test textile after at least partially curing the adhesive primer and inspecting the joining surface by means of a qualitative evaluation of the fracture pattern between the cured adhesive primer and the planar test textile and/or by means of a quantitative evaluation of the pull-off force determined when pulling off the planar test textile.

An ultrasonic bonding tool is used on a horn side or anvil side of an ultrasonic joining device in which two synthetic resin sheets that include a polyethylene layer, a polypropylene layer and a ceramic heat-resistant layer are superposed and joined together so that the heat-resistant layers face each other. The ultrasonic bonding tool includes a plurality of protrusions shaped as quadrangular pyramids having a flat top surface. Each of the protrusions has an apex angle formed by two mutually opposite side surfaces that is within a range of 110-130. When two separators of a battery cell are joined together using the ultrasonic bonding device with the ultrasonic bonding tool, a force with which the separators adhere to the protrusions is weak. In this way, the separators do not adhere to the horn during ultrasonic bonding of the synthetic resin sheets.

The present disclosure relates to methods and apparatuses for mechanically bonding substrates together. The apparatuses may include a pattern roll including a pattern element protruding radially outward. The pattern element includes a pattern surface and includes one or more channels adjacent the pattern surface. The pattern roll may be positioned adjacent an anvil roll to define a nip between the pattern surface and the anvil roll, wherein the pattern roll is biased toward the anvil roll to define a nip pressure between pattern surface and the anvil roll. As substrates advance between the pattern roll and anvil roll, the substrates are compressed between the anvil roll and the pattern surface to form a discrete bond region between the first and second substrates. As such, during the bonding process, some yielded substrate material flows from under the pattern surface and into the channel to form a channel grommet region.

A laser welded structure is formed by laser welding together a resin molded body formed from a thermoplastic polymer alloy containing a crystalline resin and an amorphous resin and a metal body made of a metal. A glass transition temperature of the amorphous resin is lower than a melting start temperature of the crystalline resin.

A package that is suitable for packaging an article for collecting or administering a pharmaceutical active substance is disclosed. The package includes a first packaging component that includes a product-contacting sealant layer that includes a first ethylene vinyl alcohol copolymer. The package includes a second packaging component that includes a product-contacting sealant layer that includes a second ethylene vinyl alcohol copolymer. The ethylene content of the second ethylene vinyl alcohol copolymer is equal to or less than about 38 percent and the ethylene content of the first ethylene vinyl alcohol copolymer is greater than the ethylene content of the second ethylene vinyl alcohol copolymer.

The present disclosure is concerned with a method of forming a seal with a polyethylene based film structure. The polyethylene based film structure has at least one layer formed with an oriented polyethylene having a predetermined melting temperature (T.sub.m). A conductive heat sealing device provides heat to form the seal, where a first sealing bar of the conductive heat sealing device operates at a first operating temperature of at least 10 degrees Celsius (? C.) below the T.sub.m of the oriented polyethylene in the polyethylene based film structure and a second sealing bar of the conductive heat sealing device operates at a second operating temperature of at least 15? C. higher than the operating temperature of the first sealing bar. The seal formed with the polyethylene based film structure retains at least 99 percent of its original surface area prior to forming the seal.
