Packaging design terms glossary

Letter A

A.C.L.
Applied color lettering. Colored lettering or design of a ceramic nature fused onto bottles. Employs screen printing to transfer glass frit (powdered glass colorant) to the surface of a bottle or glass container. The design is fired, heated in a lehr, and becomes permanently fused.

ABS
Acrylonitrile-butadiene styrene (ABS). Tough, hard, rigid, opaque plastic easily fabricated by injection molding, extrusion and thermoforming. More costly than general purpose and impact grades of polystyrene. Of limited use in packaging.

Accelerated Test
Laboratory performance test of a container or coating to evaluate its performance in a shorter time interval than that required under actual service conditions. Example: Performing chemical-resistance tests at elevated temperatures.

Acid Rain
Acid rain refers to a mixture of wet and dry deposition (deposited material) from the atmosphere containing higher than normal amounts of nitric and sulfuric acids. The precursors, or chemical forerunners, of acid rain formation result from both natural sources – volcanoes and decaying vegetation – and man-made sources – primarily emissions of sulfur dioxide (SO2) and nitrogen oxides (NOx) resulting from fossil fuel combustion. When fossil fuels are combusted, acid-forming nitrogen and sulfur oxides are released to the atmosphere. These compounds are transformed in the atmosphere. These compounds are transformed in the atmosphere, often traveling thousands of kilometers from their original source, and then fall out on land and water surfaces as acid rain. Acid rain is best known for the damage it causes to forests and lakes. Less well known are the many ways it damages freshwater and coastal ecosystems, soils and even ancient historical monuments, or the heavy metals these acids help release into groundwater.

Acrylic

Dimension “H”
BOTTLE “H” Dimension: The height of the neck finish. Measured from the top of the neck to the point where the diameter “T”, extended down, intersects the shoulder. The bottle finish “H” must be greater than closure “H” (corrected for the thickness of the compressed liner or other sealing elements). CLOSURE “H”: The “H” dimension is measured from the inside top of the closure vertically down to the bottom of the closure skirt. Effective “H” must take into consideration the liner, or other sealing element, if one is used. To determine effective “H”, liner thickness or other sealing element under compression must be determined and subtracted from unlined “H”.

Dimension “I”
The minimum opening through the finish and neck expressed by measuring the inner diameter of the neck at its narrowest point. Specifications require a minimum “I” to allow sufficient clearance for filling tubes. Linerless closures, with a plug or land seal, and dispensing plugs and fitments require a controlled “I” dimension for proper fit.

Eutrophication
Eutrophication is a process whereby water bodies, such as lakes, estuaries or slow moving streams, accumulate nutrients that stimulate excessive algal growth. Nutrients can come from many sources, such as: 1) fertilizers applied to agricultural fields, golf courses and suburban lawns; 2) deposition of nitrogen from the atmosphere; 3) erosion of soil containing nutrients; 4) sewage treatment plant discharges; and 5) the burning of fossil fuels. As the algae grow faster, they shade existing plants until both the algae and some plants die off. As the dead algae and plants are decomposed by microbes, dissolved oxygen is used up, creating an anoxic condition – an environment without oxygen. Such an environment becomes unsuitable for plants and animal life. Algal blooms also lead to oxygen depletion resulting in fish population decline and the creation of aquatic conditions that can be harmful to human health.

Greenhouse Gases
Gases that trap heat in the atmosphere are often called greenhouse gases. Some greenhouse gases such as carbon dioxide occur naturally and are emitted to the atmosphere through natural processes and human activities. The international Panel on Climate Change (IPCC) recognizes four primary greenhouse gases (GHGs). These are water vapor (H2O), carbon dioxides (CO2), nitrous oxide (N2O) and methane (CH4). However, the IPCC and other leading climate change agencies include a number of entirely human-made gases in their GHG inventory which by category, include halocarbons and other chlorine and bromine containing substances, also known as fluorinated gases, which are dealt with under the Montreal Protocol, and sulphur hexafluoride (SF6), hydrofluorocarbons (HFCs) and perfluorocarbons (PFCs) dealt with under the Kyoto Protocol. Carbon dioxide has a global warming potential of one, while methane and nitrous oxide have warming potentials of 25 and 310 respectively. Fluorinated gases can be intense greenhouse gasses with the multiplier for sulfur hexafluoride (SF6) being 23900 times as potent as carbon dioxide. A complete list of pertinent GHGs can be found on the IPCC website. The principal greenhouse gases that enter the atmosphere because of human activities are:

Carbon Dioxide (CO2): Carbon Dioxide enters the atmosphere through the burning of fossil fuels (oil, natural gas and coal), solid waste, trees and wood products, and as a result of other chemical reactions (e.g., manufacturing cement).

Methane (CH4): Methane is emitted during the production and transport of coal, natural gas and oil. Methane emissions also result from waste elimination by livestock, some agricultural processes and by the decay of organic waste in municipal solid waste landfills.

Nitrous Oxide (N2O): Nitrous oxide is emitted during agricultural and industrial activities, as well as during combustion of fossil fuels and solid waste.

Fluorinated Gases: Hydrofluorocarbons, perfluorocarbons and sulfur hexafluoride are synthetic, powerful greenhouse gases that are emitted from a variety of industrial processes. Fluorinated gases are sometimes used as substitutes for ozone-depleting substances (i.e., CFCs, HCFCs, and halons). These gases are typically emitted in smaller quantities, but because they are potent greenhouse gases, they are sometimes referred to as High Global Warming Potential gases (“High GWP gases”).

The resulting opaque material offers good dimensional stability, low-temperature impact strength and rigidity. HIPS is readily molded to precise tolerances. It can be combined with other plastic parts to make units which are attractive and tough. Disadvantages include poor barrier properties, and poor grease resistance.

Hollow Neck

Hot Check
An edge or side defect. A check characterized by deep V-shaped cracks appearing on the edge or side.

Hot Filling
The product, usually a liquid, is passed through a heat exchanger and then filled at elevated temperatures. The closure is then applied. Any microbiological contamination on the inner surfaces of the container (usually a bottle) is destroyed by the hot liquid without heating the bottle itself, as in the technique of in-bottle pasteurization.

Hot Stamping
This decorating technique utilizes a die (design) that cuts metal foils from a ribbon and by heat, embosses the design onto the surface of the plastic containers. Often used in conjunction with silkscreening on cosmetic containers such as those used for shampoos and conditioners.

LF
Lubricant Finish (LF). Lubricant finish treatment is used to ì reduce excessive removal torque build-up found with plain vinyl and P/E coated papers. These papers have a tendency to cold flow after the closure is applied, causing removal torque build up, which is is accentuated with time and temperature. The LF coating is effective in minimizing this problem. The LF coating is also used with Saran film, which has a tendency to grasp the glass sealing surface during capping. This results in erratic capping performance and false application values. Closures which appear to be on tight are reduced to approximately zero removal torque with only slight impact on handling. To overcome this tendency and insure good application and removal torque performance, the LF coating of wax treatment is used.

Life Cycle Assessment
LCA is the “compilation and evaluation of the inputs, outputs and the potential environmental benefits and impacts of a product system throughout its life cycle” (ISO 14040:2006). It is a rigorous approach to assessing environmental aspects and potential impacts of industrial or other systems. LCA enables the estimation of the cumulative impacts resulting from all stages in the product life cycle, often including impacts not considered in more traditional analyses (e.g., raw material extraction, material transportation, ultimate product disposal, etc.). The LCA methodology may be applied on individual phases of a life cycle, e.g., a manufacturing process. Partial life cycle assessments are called cradle-to-gate or gate-to-gate. A full life cycle assessment is known as cradle-to-grave assessment.

Cradle-to-gate: Cradle to gate is a partial life cycle assessment process that includes the resource acquisition and production/manufacturing phases until a specified point (the gate), depending on who is doing the assessment. In terms of packaging, cradle-to-gate measurement may, for instance, include the growth, harvest or extraction and processing of raw materials, processing of recycled or reused materials, production of final packaging materials, conversion of final packaging materials into packaging components, assembly of packaging components into units of packaging and filling of packaging components, as well as the transport functions that are required to move materials, components and units of packaging from one supply chain partner to another up until product is put into the packaging.

Gate-to-Gate: Gate-to-Gate is a partial life cycle assessment process of only one phase of the life cycle. In terms of packaging, gate-to-gate measurement may, for instance, assess the physical and functional attributes or conditions related to packaging that occur during the period of time a supply chain partner owns or is responsible for packaging material, packaging components or units of packaging up to the point of transfer to the next partner in the supply chain.

Cradle-to-Grave: Cradle-to-Grave is a full life cycle assessment that includes resource acquisition to final disposition. In terms of packaging, cradle-to-grave measurement would include the growth, harvest or extraction and processing of raw materials, processing of recycled or reused materials, production of final packaging materials, conversion of final packaging materials into packaging components, assembly of packaging components into units of packaging, filling of packaging components, use of packaging and end-of-life management of packaging/packaging materials. It would also include any transport functions that are required to move raw, recycled, reused or final packaging materials, packaging components and units of packaging from one supply chain partner to another. But, it would not include transport of packaging that contains product.

Life Cycle Inventory Data
Life cycle inventory data is the data collected or derived during a life cycle inventory analysis. A life cycle inventory analysis is the process of examining all the inputs and outputs in a product system’s life cycle, beginning with what the product is composed of, where those materials came from, where they go and the inputs and outputs related to those component materials during their lifetime. The purpose of the inventory analysis is to quantify what comes in and what goes out, including the energy and material associated with materials extraction, product manufacture and assembly, distribution, use and disposal and the environmental emissions that result.

Polyallomer (PA)
Polyallomer is an essentially linear copolymer with repeated sequences of ethylene and propylene. It combines some of the advantages of both polymers. Polyallomer is autoclavable, and offers much of the high temperature performance of polypropylene. It also provides some of the low temperature strength and flexibility of polyethylene.

Polycarbonate
Polycarbonate is window-clear, amazingly strong, and rigid. It is autoclavable , nontoxic and the toughest of all thermoplastics. PC is a special type of polyester in which dihydric phenols are joined through carbonate linkages. These linkages are subject to chemical reaction with bases and concentrated acids, cydrolytic attack at elevated temperatures (e.g. during autoclaving), and make PC soluble in various organic solvents. For many applications, the transparency and unusual strength of PC offset these limitations.

Polyethylene

Polymer
A high molecular weight organic compound, natural or synthetic, whose structure can be represented by a repeated small unit, the polymer; i.e., polyethylene, rubber, cellulose. Synthetic polymers are formed by addition or condensation polymerization of monomers. If two or more monomers are involved, a copolymer is obtained. Some polymers are elastomers, some plastics.

Polyolefins
Polyolefins are high molecular weight hydrocarbons. They include low-density and high-density polyethylene, and polypropylene. All are break resistant, nontoxic, and non-contaminating.

All polyolefins can be damaged by long exposure to ultraviolet light.

Polypropylene
Polypropylene is similar to polyethylene, but each unit of the chain has a methyl group attached. It is tranlucent, autoclavable, and has no known solvent at room temperature. It is slightly more susceptible than polyethylene to strong oxidizing agents. It offers the best stress-crack resistance of the polyolefins. Products made of polypropylene are brittle at ambient temperature and may crack or break if dropped from benchtop height. Used in film, in sheet and for molded rigid containers.

W (Full Wax)
Full Wax (W). Full wax treatment is generally used on wide mouth closures as a caulking agent. It is difficult for many liner facings to provide a satisfactory seal on wide mouth containers. The larger the finish, the greater the tolerance in both container and finish. Inherent waves and dips in large finishes also contribute to this condition. The full wax treatment is generally suggested for closures 58mm and above, primarily as a sealing aid. It also provides an additional moisture barrier and acts as a lubricant similar to the LW and LF coating treatments.

Water Consumption and Use
The term “water consumption” is used to indicate; 1) fresh water (excluding rain) that is mechanically diverted from a source and then used in such a way that it is not available again as liquid fresh water; or 2) water that is degraded during use such that it cannot be collected for reuse. The difference between water “use” and water “consumption” is that consumption causes the water to become unavailable for direct or immediate use. An example of water “use” is water used in paper production processes that is collected, processed and reused on site. An example of water “consumption” is water that evaporates during a production process. Another example of water consumption is water that becomes an ingredient of a final material such as that used in water-based ink.

Water Vapor Perm

This property has measurable values that can be determined under specified conditions of time, temperature and the water vapor pressure differential between two sides of a material or between two sides of material or between the inside and the outside of a container.

Wavy Appearance
A general defect. Irregular surface on either the inside or outside of the container.

Wax Coatings
Wax is widely used as a component of liner facings and serves three principal functions: 1) Lubricates the facing. This prevents excessive adherence to the glass or plastic finish, which may cause closures to be difficult to remove. 2) Reduces vapor transmission. Many dry products are packaged using liners, which depend on wax entirely as the vapor barrier. 3) Acts as a caulking agent. On widemouth containers, the wax helps to compensate for surface variations in the container finish.
