(1) The
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

Easy-opening can
A can
equipped with an opening feature which can be removed or opened by hand
without the need for any tools such as a can opener.
|
Edge crush test
Measures
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
it.
|
Elastic limit
The point
beyond which a material breaks or is subject to non-elastic deformation when
stretched.
|
Elastomer
A
substance having rubber-like elastic qualities.
|
Electronic composition
The
process of setting type whereby all input and output is completed in
electronic format
|
Electronic sealing
The
sealing of two surfaces of thermoplastic films by inducing high-frequency
electric current to cause heating and fusion between them.
|
Electrostatic printing
(xerography)
Ink, in
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.
|
Elmendorf test (tear test)
A method
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.
|
Elongation
The
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.
|
Embossing
Producing
impressed designs on the surface of paper for example by the use of special
dies or rollers.
|
Emulsion
Two or
more normally immiscible materials held together in a liquid homogeneous
mixture by the influence of a third agent (emulsifying agent).
|
Enamel
A type of
coating specially designed to dry to a hard, high-gloss finish.
|
End
(1) One
of the faces of a rectangular container, usually one that has the smallest
area.
(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
factory-applied end.
(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.
|
Envelop (Verb)
To wrap
or enclose an item.
|
Envelope (Noun)
A
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.
|
Epoxy resins
Thermosetting
plastics made by the reaction of epoxies with other materials such as amines,
alcohols, phenols, acids and unsaturated compounds.
|
Etching
The
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.
|
Ethylene vinyl acetate (EVA)
A plastic
resin normally used in combination with other plastics in making film, coatings
and adhesives.
|
Excelsior
Shredded
wood used for cushioning.
|
Expanded plastic
A plastic
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.
|
Expendable pallet (one-way)
A pallet
of light construction and low-cost materials which permit it to be discarded
after its first usage.
|
Expiry date
The date
after which a perishable product should not be used, normally marked on the
package, also referred to as the ‘use-by’ date.
|
Export package
A package
specifically designed for transportation to and distribution in a foreign
market.
|
Extender
A
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,
primary ingredient.
|
Exterior package
A
container designed to support or contain one or more smaller packages,
usually retail packages.
|
Extrusion
The
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
and sheeting.
|
Extrusion coating
The
application of an extruded thermoplastic material onto the surface of paper,
film or foil.
|
Extrusion lamination
The use
of an extruded material as an adhesive binder between two base webs of
material.
|
