example 1

[0052] according to figure 1 and figure 2 The pouches are used on the FFS machine Figure 6-7 The sealing clips are formed from thin sheets. The FFS machine produces all seals by heating to create a thermal bond between the individual sheets. The sheet is the film material polyethylene terephthalate, metal film (such as ) and a three-layer laminate of polyethylene. Sheets are provided on rolls fed into the FFS machine and drawn onto the area where tubes are formed by sealing fin seals in the machine direction. The tube has a leading edge that is used according to Figure 6-7 The sealing jaws seal to form the leading edge seal. Fill and deposit a predetermined weight (2kg) of granular laundry detergent into the tube, and use Figure 6-7 The sealing jaw seals the tube to form a filled pillow pouch containing 2 kg of granular laundry detergent. The process is then repeated for the next pouch.

Abstract

A pouch (100) with a sheet (120) containing at least one layer of a film material is provided. The sheet forms a tube (138) which is closed with a seal (122) to form a volume (140). The seal (122) contains a first straight edge (128) and a second straight edge (130) adjoining the first straight edge (128). The first straight edge (128) forms an obtuse angle with the second straight edge (130). A sealing jaw (150) and a method for forming the pouch are also described.

Description

technical field [0001] The present invention relates to pouches. In particular, the present invention relates to sealed pouches formed from film materials. Background technique [0002] Pouches are typically formed from laminates or films, and can be used to hold many types of items, such as food, shampoos, detergents, pharmaceuticals, and the like. To prevent them from leaking, they are often sealed on all sides to form a fixed volume to hold products such as granular detergents. However, finding a balance between sachet waste and strength against rupture and leakage has been a challenge. The strength of the seal is proportional to the sealing area itself. If the pouch is sealed with an excessively large sealing area on the sides, the given volume of film per area is less, resulting in wasted film. However, if the sealing area is too narrow, the pouch will easily rupture (if dropped). [0003] The pouches are usually sealed with a straight seal forming an angle of abou...
