Abstract: Provided is a device (400) for forming a pouch. The device can include a first sealing section (404) having a curved heat-transfer surface, and a second sealing section (406). The second sealing section (406) can include a first heat-transfer surface (407), a second heat-transfer surface (405), and a heated cutter (408). The heated cutter (408) can be disposed between the first heat-transfer surface (407) and the second heat-transfer surface (405). The device can also include an optional cutting face that accepts the heated cutter.

Abstract: A container and product system comprising a container adapted to house a product, the container comprising a substantially transparent multi-layered laminate body and a product housed in the container, the product comprising dyes, lakes, or both.

Abstract: A laminate ma tend comprising in sequence from outermost layer to innermost layer: (a) an outer sealant layer comprising a thermoplastic polymer, (b) a paper layer, (c) a barrier layer, and (d) an inner sealant layer comprising a thermoplastic polymer, wherein the paper layer has a Scott bond strength of 250-450 J/m2 is provided.

Abstract: A container is provided for substances that contain an antibacterial compound. The container has a tube body and a tube shoulder. The tube shoulder is made of an alkene based polymer such as a polyethylene or a polypropylene. Such alkene based polymers have a high absorptivity for antibacterial compounds such as triclosan. The shoulder includes a barrier unit. The barrier unit is made of a polymeric material such as polytrimethylene naphthalate, polyethylene naphthalate and acrolonitrile/methacrylate. This barrier unit can be a film on the tube shoulder or a co-injection molded insert in the shoulder. The absorption is less than 10 mg/dm2.

Abstract: A container is provided for substances that contain an antibacterial compound. The container is comprised of a tube body and a tube shoulder that includes a tube nozzle. The tube body may have a laminate structure. The tube shoulder may be comprised of an alkene based polymer such as a polyethylene or a polypropylene. Such alkene based polymers have a high absorptivity for antibacterial compounds such as triclosan. It has been found that the absorptivity for triclosan can be reduced through the use of at least one of polytrimethylene naphthalate, polyethylene naphthalate and acrolonitrile/methacrylate as the surface contacting the composition containing the antibacterial. This surface can be a film on the tube shoulder/nozzle, the full structure of the tube nozzle, an insert in the tube nozzle or a co-injection molded surface on a shoulder/nozzle. The absorption is less than 1.0 mg/dm2.

Abstract: A dual chamber sachet with a dispensing outlet can be made in a form/fill sequence by attaching the dispensing outlet to the film that is to form the chamber divider wall followed by attaching films that are to form the outer walls of the sachet to the dispensing outlet. The upper and side lateral edges of the sachet then are sealed together to produce a sachet with an open bottom end. The sachet can be produced from three film sources, two film sources with the outer walls being formed from a single film, or from a single film formed into a W-shape. The sachet preferably is filled through the open bottom end and the bottom end then sealed. However the sachet can be top filled through the nozzle. The sachets then are severed one from the other by cutting along a lateral seal and packed into a carton, or preformatted along a lateral seal and cut to produce a string of a set number of sachets. The sachets can have a single use dispensing outlet or a reclosable dispensing outlet.

Abstract: Injection stretch blowmolded polyester tubes have been developed for use in packaging water-containing products. Polyester resins have good barrier properties for organic materials but poor moisture barrier properties. It has been found that the moisture barrier properties can be increased by coating the exterior surface of the tube with a first material which adheres to the tube polyester surface and to an overlayer of a moisture barrier comprising polyvinylidene chloride, However, since the overlayer of polyvinylidene chloride can develop a yellow tint, the overlayer in one embodiment is coated with an opaque decorative layer to prevent or mask the gradual yellowing of the polyvinylidene chloride overlayer. In another embodiment where the tube is to be substantially transparent, the product in the tube will have a color that will substantially cancel the yellow tint that is developed by the polyvinylidene chloride overlayer.

Abstract: A pouch package is formed that has a multilayer structure of two or more layers where the longitudinal seal is formed from a bonding of the inner layer to the inner layer in a fin seal arrangement. One layer of the multilayer structure is a seal layer and another layer a barrier layer. There can be additional layers such as additional barrier layers and cutter lubricant layers. It is preferred that the multilayer structure have two to four layers (not counting adhesive tie layers) and that the inner seal layer be readily sealable by means of radio frequency energy. The longitudinal seal will preferably be along a side surface so as to have a spout. The pouch is made on form/fill equipment from a multilayer sheet by the multilayer sheet being formed into a tubular member with a longitudinal seal.

Abstract: A pouch container can be produced for household products such as bleaches using a multi-layer film and RF sealing techniques. The film has at least one barrier layer and at least one seal layer. The film also has an oxygen permeability of at least about 600 cm.sup.3 /m.sup.2 /day/bar and a transmissivity for fragrances. In addition, the film should be of an age after manufacture of about 2 weeks to about 24 weeks. The pouches that are formed have strong seals and overall strength.
