摘要:
This disclosure provides new heat sealable, barrier laminate packaging structures used for beverage component pouches or cartridges, including new structures and chemical compositions of the pouch made to contain the beverage base, component, or component concentrate. These structures and compositions used for heat sealable, barrier laminate packaging balance good heat sealability with improved performance for flavor scalping, oxygen permeability, and/or undesirable moisture ingress or egress, which affect the stability and useful life of the pouch or cartridge and its contents.
摘要:
The invention concerns a device (10) for continuously treating a web substrate (15a) in a plasma enhanced process. The device (10) contains at least one treatment station (12a, 12b) with a vacuum process chamber, wherein at least one plasma treatment unit (13a, 13b) is allocated to the at least one treatment station (12a, 12b) which is designed to form a plasma zone (14a, 14b) within the process chamber for treating a surface of the web substrate (15a). The device (10) further contains a transporting system for continuously transporting the web substrate (15a, 15b) through the at least one treatment station (12a, 12b), with an unwind roller (20) and a rewind roller (21), wherein the transporting system defines a transporting path of the web substrate (15a) through the process chamber. The plasma treatment unit (13a, 13b) contains at least one extensive antenna and at least one radiofrequency generator for exciting said extensive antenna to at least one of its resonant frequencies, wherein the transporting system in the process chamber defines a treatment path section for the web substrate (15a), wherein the treatment path section for the web substrate (15a) lies opposite to and spaced from the extensive antenna.

The present disclosure provides a multilayer formable barrier film having a thickness ranging from 100 to 750 micron comprising. The film comprises i) a substrate layer comprising a) a PVC film, optionally laminated with a PE film and, b) at least one layer of PVDC as a barrier layer; and ii) a base layer comprising a) a PVC film, optionally laminated with a PE film and, b) at least one layer of PVDC as a barrier layer, said base layer laminated to said substrate layer through an adhesive coat.
摘要:
Die vorliegende Erfindung betrifft eine mindestens monoaxial gereckte, mehrschichtige Kunststofffolie mit Trennwirkung und einer Gesamtdicke ≤ 18 μmι, vorzugsweise ≤ 12 μm, die auf mindestens einer Oberfläche eine mindestens partielle Prägung aufweist.
摘要:
A packaging for a tea pouch, a method of making the packaging, and a tea pouch made from the packaging are disclosed. The packaging includes a paper substrate and a coextrusion including an ethylene vinyl alcohol layer. The ethylene vinyl alcohol layer is directly attached to the paper substrate. Packaging of this type exhibits excellent barrier properties, may be heat sealed under pressure to form a tea pouch without substantial amounts of squeeze out, and does not present the cost or disposal issues associated with some other types of packaging.
摘要:
The present invention relates to a non-foil packaging laminate for liquid food packaging comprising two or more layers of paper or other cellulose-based material, outermost liquid tight, heat sealable layers of polyolefin-based polymers, and barrier layers coated onto the inner side of the first layer of paper or cellulose-based material. The invention also relates to a method for manufacturing the packaging laminate and to a packaging container that is made from the packaging laminate.
摘要:
A method of making multilayer paper-based packaging materials with enhanced barrier performance is disclosed that is economical on a per-package cost basis. The disclosed method comprises steps of coating a water-based barrier composition on-line during papermaking process onto at least one surface of the paper-based substrate, and then applying a polymeric film onto the surface of the resulting coated paper-based structure. When desired, the disclosed method may include a step of applying a layer of base coat between the paper-based substrate and the barrier layer to enhance the surface smoothness and reduce the porosity of the paper-based substrate.
