A plastic thread bonding method and structure for folding edge of a FIBC includes setting the folding edge of the FIBC flatly on a metal solid surface; using a cooling device to maintain a condensation temperature of the solid surface; performing a needle insertion action of the folding edge by a plastic injection needle, and condensing and crystallizing at the eyelet to form a base point; performing a needle withdrawal action by the plastic injection needle to fill up a melted plastic into the eyelet, applying a pressurized cold air to condense the melted plastic to from a thread post; performing a horizontal translation action of the plastic injection needle or the folding edge, and applying the pressurized cold air to condense the melted plastic to form a thread bridge; and repeating the aforementioned procedure to form a next base point, a next thread post and a thread bridge.

Bags for containing various retail items, such as food items, and methods of forming the same. In some aspects, a bag having a top and bottom is provided. The bags can include a first layer and a second layer opposite the first layer and uniformly extending from the first layer. In some aspects, the bag can further include a first side seam between a side of the first layer and an opposing side of the second layer and a second side seam between a side of the second layer and an opposing side of the second layer. The first layer and the second layer each have an un-folded edge substantially parallel to the bottom fold. In some aspects, the bags include a bottom V-shaped fold extending along a transverse axis relative to the first side seam and the second side seam, the bottom V-shaped fold forming a seamless bottom.

A process for producing bags comprising: feeding a bottom web, a first side web and a second side web in a conversion process, each of the webs having a first side edge and a second side edge, wherein the first side edge of the first side web is aligned with the first side edge of the second side web, the second side edge of the first side web is aligned with the first side edge of the bottom web, and the second side edge of the second side web is aligned with the second side edge of the bottom web, thereby forming an inverted T-shaped web comprising a base having first and second wing portions and a riser, wherein the first wing portion comprises the bottom web and first side web, the second wing portion comprises the bottom web and the second side web, and the riser comprises the first and second side webs; sewing the first side web to the bottom layer in the first wing portion with a repeating pattern comprising a truncated triangle having a narrow portion and wider portion, and a tab separating the triangles, wherein the narrow portion of the triangle points toward the second side edge of the first side web; sewing the second side web to the bottom layer in the second wing portion with a repeating pattern comprising a truncated triangle having a narrow portion and wider portion, and a tab separating the triangles, wherein the narrow portion of the triangle points toward the second side edge of the second side web; contacting the first and second wing portions by folding them toward each other, thereby forming a folded web; rotating the folded web to the horizontal; sewing the first and second webs together in the riser with a repeating pattern comprising a flat-bottomed U shape with tabs separating the repeating U's, where the flat bottom of the U faces the first side edge of the first and second side webs, and the tabs separating the flat-bottomed U's are bisecting the tab separating the triangles in the first and second wing portions, thereby forming a web of sewn bags; cutting the web along the edge of sewn bags to remove the sewn portion corresponding to the flat bottom portion of the flat bottom U shape parallel to the edge, thereby forming a web of open top bags; and transversely cutting the web of open top bags at the middle of the truncated triangles and bisecting the repeating U's, thereby forming separate, open bags, and optionally scrap material.
