Multi-layer films for making bags for containing flowable materials, in particular to large bags for dairy products. The multi-layer films have an outer and an inner sealant layer and a core layer and optionally, an interposed layer positioned between the outer sealant layer and the core layer and between the core layer and the inner sealant layer. The outer and inner sealant layers contain an ethylene/α-olefin interpolymer composition and the intermediate layer optionally contains this interpolymer composition.

An improved paperboard pouch comprising a multilayer substrate and a method of making the same is provided. The multilayer paperboard pouch comprises an outer surface and an inner surface, wherein one of the surfaces is defined as a food contact surface. In the depicted embodiment, the properties of the polymer layer are chosen to provide adequate mechanical and barrier protection to the paper-based pouch formed on the conventional pouch-forming equipment. A method of manufacturing a multilayer paperboard pouch using conventional bag-making equipment (“CBME”) running at normal production speed for making standard plastic pouches is also provided. First, a paper is extrusion-coated and then the CBME is configured with a feeder for feeding an extrusion-coated paper intermittently for a length along a feeding path; a cutter disposed at a position predetermined for cutting one of the layers of the coated paper and forming a first side gusset, a second side gusset and a bottom gusset portions and for folding each of a first side gusset, a second side gusset and a bottom gusset portions into halves along a center line extending longitudinally thereof; and a sealer for sealing the layers of the polymer with the layers of the bottom gusset portion and the layers of the first and second gusset portions, respectively to form the finished multilayer paperboard pouch ready for sale and distribution to various retailers. It is to be noted that in the depicted embodiment various closure constructions and mechanism can be used for heat sealing the finished pouches.

Described herein is a method of forming individual tubes or sachets containing fluent material, and a packaging machine for doing so, are described. The side of the foil which will be in contact with the fluent material when the package is formed is exposed to plasma in mist or aerosol form as the tube or sachet is formed from a strip of laminate material (1), which is folded about a former (2) into a closed tube or sachet which passes over the open end of a dispensing tube (3) from which the fluent material is dispensed. A mist of plasma is injected into the interior of the material tube as it is formed, extracted from the area once it has passed over the interior walls of the laminate tube.

A particle removal device for a filling machine configured to form, fill, and seal individual packages is provided. The particle removal device comprises an air supply pipe, and a controller being programmed to activate the particle removal device such that a jet of air is directed into a ready-to-fill package passing the particle removal device.

Even when the filling speed increases, the surface temperature of a molded bottle falls within a constant range, and a sterilizer adequately sterilizes the bottle.

A preform is heated, the heated preform is sealed in a mold, the preform sealed in the mold is blow-molded into a bottle, the surface temperatures of a neck portion, a body portion, and a bottom portion of the molded bottle are measured, and the mold temperatures of a neck portion, a body portion, and a bottom portion of the mold is so adjusted that the measured surface temperature of the bottle falls within a specified temperature range.

Provided is a device for processing containers, in particular plastic containers, including at least one container-processing apparatus, which has at least one changeover access entry, at which at least one of format parts and tools can be exchanged during changeover operation, and including a transport system, by means of which the at least one of format parts and tools can be brought to the at least one container-processing apparatus. The transport system is a driverless transport system, by which the format parts and/or tools can be automatically brought to at least one container-processing apparatus.

This disclosure provides new containers, preforms, methods, and designs for small and light-weight carbonated beverage packaging that provide surprisingly improved carbonation retention and greater shelf life, while still achieving light weight. This disclosure is particularly drawn to small PET containers for carbonated beverages, for example less than or about 400 mL, and methods and designs for their fabrication that attain unexpectedly good carbonation retention and shelf life.

An apparatus for producing packaging, in particular composite packaging for liquid foodstuffs, having a cross-sectional area that decreases in the pour-out direction in the gable region. The packaging is composed of a sleeve having a gable region having a plurality of gable faces and a pouring element. The apparatus has at least one rotatable mandrel wheel having a plurality of mandrels for holding the sleeves. Additionally, a method for producing such packaging and a gable press for use with the aforementioned apparatus. In order to allow easier and more cost-effective production, it is proposed that the apparatus has a gable press, assigned to a single mandrel wheel position, for folding the gable region, for connecting all the gable faces of the gable region of the sleeve to the pouring element and for sealing the protruding ears in the same mandrel wheel position.
