Article Numbering System, a bar coding system originating in Europe, for
product identification. See also: U.P.C.
ear-like extensions which appear at the corner of sacks after they are filled
and closed. Appear.
(2) ear, Van Buren. The extended flap on a soap or other
carton which folds and seals on the outside side panel of the carton, thus
making carton more siftproof.
(3) (4) Ears are attached to metal pails to
hold bail or handle.
(5) Name given the finger grip of pressed glass between
the shoulder and finish of a glass jug to facilitate holding it.
equipped with an opening feature which can be removed or opened by hand
without the need for any tools such as a can opener.
the ability of a small vertically placed sample of corrugated board to
withstand compression in the plane of the board. Indicates
rigidity of the corrugated board and compressive strength of a box made from
beyond which a material breaks or is subject to non-elastic deformation when
substance having rubber-like elastic qualities.
process of setting type whereby all input and output is completed in
sealing of two surfaces of thermoplastic films by inducing high-frequency
electric current to cause heating and fusion between them.
atomized or powdered form, is electrically charged in varying degrees
according to the density of the image and is thereby attracted to and
deposited on the surface.
for testing the tear strength (resistance to tearing) of a packaging
material. The test measures the energy required to extend a tear of specified
length in a tape, or
other material, once the tear has been started by an intentional precut.
increase in length of a material under tensile stress (stretching). Data is
expressed in terms of percentage increase in length to the breaking point.
See also: Elastic limit.
impressed designs on the surface of paper for example by the use of special
dies or rollers.
more normally immiscible materials held together in a liquid homogeneous
mixture by the influence of a third agent (emulsifying agent).
A type of
coating specially designed to dry to a hard, high-gloss finish.
of the faces of a rectangular container, usually one that has the smallest
(2) The head or bottom of a cylindrical container. In can making, can
lids are referred to as ends: Top end or customer's end and Bottom end or
(3) In set-up paper boxes, the piece of boxboard
attached to the base or side of an ended box.
(4) A discontinuity in a foil
web or other sheet material, usually caused by breaks.
or enclose an item.
flexible flat package having two normally rectangular faces and joined at
three edges to form an enclosure. The non-joined edge may be closed after
filling by any of several methods: adhesive interlocking flap, heat seal,
string tie or metal fastener.
plastics made by the reaction of epoxies with other materials such as amines,
alcohols, phenols, acids and unsaturated compounds.
process of producing a design on metal or glass by causing the surface to be
eaten away by a corrosive substance or cut by a sharp point.
resin normally used in combination with other plastics in making film, coatings
wood used for cushioning.
in the form of a foam (cellular) made by thermal and/or chemical means and
having cushioning and insulating properties. Low moulding pressures and
economical tooling make foam moulding an inexpensive method of producing
complex cushioning components. Plastic foams are commonly made from
polystyrene (EPS), polyethylene, polypropylene and polyurethane.
of light construction and low-cost materials which permit it to be discarded
after its first usage.
after which a perishable product should not be used, normally marked on the
package, also referred to as the ‘use-by’ date.
specifically designed for transportation to and distribution in a foreign
substance, such as pigment, wood flour, etc., added to a product, such as an
adhesive, ink, paint, etc., to increase its bulk relative to the active,
container designed to support or contain one or more smaller packages,
usually retail packages.
forcing of plastifiable materials (rubber, thermoplastics, etc.), generally
by means of heating to fluid state and pumping by a continuous screw through
a shaping die into continuous lengths of profiles, rods, pipe, film, tubing
application of an extruded thermoplastic material onto the surface of paper,
film or foil.
of an extruded material as an adhesive binder between two base webs of
hole, often reinforced, through which to insert a string or clasp, often used
to attach a label or tag to a package.
