摘要:
A container body and base being lightweight structures designed to accommodate vacuum forces either simultaneously or in sequence. The container body and base each absorb a significant percentage of the vacuum. By utilizing a lightweight base design to absorb a portion of the vacuum forces enables an overall light-weighting, design flexibility, and effective utilization of alternative vacuum absorbing capabilities on the container body.

A packaging film for use as at least a part of a package for food or beverage products is disclosed. The packaging film includes one or more than one layer. The one layer of the single layer film or a layer of the multilayer film that in use contacts a packaged product is formed from a packaging material in the form of a polymeric material that is a non-scalping polymer that does not absorb or absorbs only minimal amounts of flavour components of the packaged product.

Method and apparatus for measuring, monitoring and/or providing an indication of material "damage" in board products, particularly Machine Direction (MD) Shear. In this regard, the present document discloses applying a predetermined force to a board product such that the board product is not deflected beyond its elastic region. The apparatus used for applying the force is preferably of a size or structure suitable for physically limiting the amount of deflection of the board product. By maintaining the board product within its elastic region as such, the occurrence of permanent damage to the board product is reduced. Hence, the disclosed method and apparatus are able to provide a non-destructive indication of MD Shear on the paperboard product being tested, and are thus suitable for use in on-line testing/monitoring of paperboard production.
