A slip of
paper, film or foil to be affixed to a container. The label usually carries a
graphic design and printed information about the product.
device for applying labels to packages. Adhesives, where used, may be applied
to the package or to the label. The machine may be fully or semi-automatic.
portion of the body of a container to which labels are affixed or decoration
1.Coatings of metal cans or other packaging
to prevent changes of taste, discoloration and other alterations in the
product. Most important types are epoxy-phenolics, acrylic, vinyl, phenolic,
2.Varnishes applied over printing to give
protection to the print or to give it a gloss finish.
or material packed in a shipping container or vehicle.
1.(Noun) A product made by bonding together
two or more web sheets or layers of material or materials.
2.(Verb) To unite two or more layers or webs
1.Wet lamination — the webs are joined with
solvent-based adhesive which must be dried by evaporation after joining.
2.Dry lamination — after the adhesive has
been applied and cured on the surfaces to be joined, the webs are bonded with
heat and pressure.
3.Extrusion lamination — a molten plastic
resin or hot melt adhesive is extruded between the two webs and cools there,
binding them together. See also: Co-extrusion.
seam made by overlapping one layer over the edge of another and sealing
together with adhesive, heat or other means. Lap seam or lap seal.
See: Lap joint.
chemical compound, usually a rubber derivative, which often serves as the
base for an adhesive filler or lining; usually water borne.
arrangement or drawing showing rough position, sizes, colour and other
details of a design.
condition at the finish of the container
such that the normal sealing
device or closure will not retain the air or liquid contents.
container having a manufacturing variance/fault characterized by sloping bottom that causes it to lean
when standing alone.
continuous-belt oven for the fusing of ceramic colours on to glass and the
annealing of glass containers.
printing process where viscous ink is applied to the surface being printed,
from raised inked surfaces made of metal or photopolymer.
A printing process using
flexible plates with raised plastic or resin. Ink is transferred from the
raised surfaces of the plate to a printing press blanket, then to the surface
to be printed.
of holding a lid on a full open head drum by means of a lever-operated
tightening device or ring that can be locked in closed position.
separate top or cover of a box or container. May be hinged or otherwise
attached to the body of the container.
pliable material which forms a rubber-like (often a latex) gasket to seal the
joints of metal cans and the seal between bottles and their closures.
profiling of products and their packaging throughout their useful life, from
initial production to disposal, also described as an assessment of their
environmental impacts ‘from cradle to grave’.
measure of the ability of a pigment, dye, or other colourant to retain its
original colour and physical properties either alone or when incorporated
into plastics, paints, inks and other coloured films or surfaces, upon
exposure to sun or other light.
(2) Ability of a plastic or other organic
film or surface to withstand the deteriorating effect of exposure to sun or
other light independently of the stability of any pigmentation it contains.
density resin produced by polymerization of ethylene with other alfa olefins
in presence of a catalyst. Offers greater strength and ease of processing,
thus giving economic advantages over conventional low density polyethylene
made by the high pressure process.
consisting only of lines and areas of solid colour.
lining or non-adhered lining material which separates a product within a
container from the container walls.
(2) One of the outer faces or the
finished surface of laminated or coated paperboard.
(3) In corrugated
boxes, a creased sheet inserted to cover any four or more panels, resulting
in double thickness walls, adding strength and other reinforcement.
(4) A bag used
inside a barrel to protect the contents from sifting, moisture and
(5) The inner bag of a double bag.
(6) A paperboard
of high bursting strength used for making fibre drums and for the facings of
(7) In closure manufacture, a specially treated material
placed inside a closure to provide a seal
that prevents leakage or deterioration of the contents.
A separate bag inserted
into another package to provide special or additional protection properties
used to line either side of the corrugated medium. Can be a kraft liner made
of virgin sulphate paperboard or a test liner containing recycled waste paper
one-component thermoplastic closure incorporating a sealing "fin"
which, when applied to a container with the appropriate finish, seals most
liquids including volatile ones.
laminated from combinations of aluminium foil, paper and plastic films,
providing an impermeable barrier pack to contain non-pressurised beverages
and liquid food, Normally supplied to packer on reels as a flattened, tubular
web and formed, filled and sealed on proprietary vertical filling machine
systems such as those of Combibloc and Tetrapack.
See: offset printing.
or group of packages representing one or several shipping units — a pallet
load, a truck load.
closing ring around the rim of a full-removable-head container intended to
retain the cover and form a seal. The ring is a circular modified
"V" or "U" section channel, the ends of which are drawn
together by means of a bolt and the periphery thus shortened, to develop the
abbreviation for “logotype”. A logotype is an identification name, symbol or
mark, including a trade mark or brandmark.
Polyethylene resin having a density below 0.925 g/cm3,
so-called conventional polyethylene, the most common type, having high gloss,
high flexibility but relatively low performance.It is mostly used for the
production of films, of coating, of molding for flexible lids, and for
flexible blow loded containers.
box, basket or other container suitable for handling or shipping fruit or
vegetables; usually refers to the relatively shallow, nailed wooden box. Also
(2) A projection on a part
or a package used for fastening or to obtain a fit between two parts.
metal fastener used for securing the top or bottom heads of a fibre drum,
steeI drum, or metal pail to the side-wall.
(4) Extensions around the
circumference of a lid which are crimped down to hold the lid securely in
place against the body of the container.
or plastic closure designed to be secured by engaging lugs on the neck or
finish of a container e.g. twist-off caps.
for metal drum or pail, with extensions around the circumference that are
bent down to hold the cover securely in place against the container body.
container finish identified by intermittent horizontal, tapered ridges that
permit the matching shaped lugs on the closure to slide between them and
fasten securely with a partial turn.
