Problems solved by technology

This prior art punch also has the disadvantage that the curved shape of one lateral edge must be complementary to the shape on the other lateral edge, thus limiting the flexibility to provide the various shapes one may wish to impart to the package

Embodiment Construction

[0027] The present invention provides a method for making packets in multiple lanes in a form fill seal (FFS) machine. Although the sachets of the present invention can be made in a horizontal or vertical FFS machine, it is preferred to make the sachets in a vertical FFS machine.

[0028] The invention relates to a method for manufacturing a packet having at least one edge comprising a non-linear portion. By "non-linear" is meant for the purposes of the present invention a shape that cannot be defined by a single straight line. The term "non-linear" includes angular bends formed when two or more wires join each other, curves of any shape and various combinations thereof. Preferably, the non-linear profile is a curved profile. The non-linear edge may be on the longitudinal edge or the transverse edge of the packet, although the non-linear edge is preferably on the longitudinal edge. By "longitudinal edge" is meant an edge defined by sealing the film in the longitudinal direc...

Abstract

The invention provides a process for the manufacture of sachets (1) in a plurality of lanes in a form fill and seal machine, one or more edges of said sachets comprising non-linear profiles (7) over at least 10% of the length of the edge, said sachets manufactured by a process comprising: (i) sealing two films (9,10) in the longitudinal direction to form a plurality of tubes parallel to each other; (ii) sealing the tubes along one end; (iii) filling the tubes with the desired material; (iv) sealing the tubes at the second end to form a plurality of sachets (1), and (v) punching out portions (8) of the sealed edges of the sachets to define the non-linear edges (7).

Description

technical field [0001] The present invention relates to a method for making packets in multiple lanes in a form fill seal (FFS) machine. Background technique [0002] Sachets have been used to pack various types of products like emulsions, powders, liquids, tablets, noodles, granules and pastes in different technical fields. Sachets allow these products to be packaged and sold in smaller quantities compared to common packaging like bottles and cans. Sachets can be conveniently used during travel as smaller quantities of so-called "unit dose" quantities can be carried without spilling. The product can be dispensed by tearing the packet and giving the product a single use, after which the packet is discarded. Selling in small packets is also convenient for new consumers who do not want to spend a lot of money trying out a new product, because the cost of the product in the packet is much lower than that sold in common units like bottles or jars. Thus, consumers who want to ...
