摘要： 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 (Tm). 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 Tm 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.

摘要： In order to prevent degradation of appearance, prevent a decrease in flexibility, and improve non-elasticity in a non-stretchable region in an elastic film stretchable structure, the invention is characterized by having an elastic film stretchable structure (20X) formed by stacking an elastic film (30) between a first sheet layer (20A) and a second sheet layer (20B), wherein a region having the elastic film stretchable structure (20X) includes a non-stretchable region (70) and a stretchable region (80) provided at least at one side of the non-stretchable region (70) in a stretching and contracting direction, the stretchable region (80) being stretchable in the stretching and contracting direction, the first sheet layer (20A) and the second sheet layer (20B) are joined via through holes (31) penetrating the elastic film (30) at the large number of sheet bond portions (40) arranged at intervals, and the non-stretchable region (70) does not have a section in which the elastic film (30) linearly continues along the stretching and contracting direction, due to presence of the through holes (31), even though the elastic film (30) continues in the stretching and contracting direction.

摘要： The invention relates to a high-strength and permanently elastic curable adhesive for bonding at least two surfaces, of which at least one surface is a surface of a permanently elastic plastic, wherein the adhesive is an adhesive that cures in at least two different hardening mechanisms, wherein the first hardening mechanism comprises a chemical reaction to form a chemical bond including a sulphur atom, and the second hardening mechanism comprises the formation of crystalline structures from amorphous polymers. The invention also relates to a method for high-strength and permanently elastic bonding of at least two surfaces to one another, of which at least one surface is that of a permanently elastic plastic, by means of such an adhesive, said method comprising the steps of: applying the adhesive to at least a first of the surfaces to be connected, ensuring conditions under which at least the first hardening mechanism of the adhesive can take place, bringing the first surface into contact with the second surface, and ensuring conditions under which the second hardening mechanism of the adhesive can take place.

摘要： A method for coupling a tube to a tube fitting includes radially outwardly expanding a tubular compression collar from a constricted state to an expanded state, the compression collar having a throughway extending there through and being made of a resiliently flexible material. An end of the tube is inserted within the throughway of the expanded compression collar, the tube bounding a passage. A tube fitting is inserted within the passage of the tube. The compression collar is allowed to resiliently rebound back towards the constricted state so that the compression collar pushes the tube against the tube fitting.

摘要： Liner having an induction heat sealable layer for sealing to a rim of a container, and a pull tab for ease of removal of the liner from the container rim. An insert is disposed between multilayer upper and lower components, has a heat bondable polyolefin layer that is thermally laminated to polyolefin layers of the upper and lower components, forming a pull tab between the integrated polyolefin layers. The resulting composite resists delamination and can be formed in a single thermal lamination step, avoiding the multiple lamination steps, associated high equipment costs, and complex layer constructions of the prior art.

摘要： A yarn or thread may include a plurality of substantially aligned filaments, with at least ninety-five percent of a material of the filaments being a thermoplastic polymer material. Various woven textiles and knitted textiles may be formed from the yarn or thread. The woven textiles or knitted textiles may be thermal bonded to other elements to form seams. A strand that is at least partially formed from a thermoplastic polymer material may extend through the seam, and the strand may be thermal bonded at the seam. The woven textiles or knitted textiles may be shaped or molded, incorporated into products, and recycled to form other products.

摘要： A machine and method for making bags is described and includes a web traveling from an input section to a rotary drum, to an output section. The rotary drum includes at least one seal bar, having a first sealing zone, and an adjacent weakening zone. The weakening zone may be a heated perforator, includes a heating wire, or be disposed to create an auxiliary sealed area.
