A Unipac (formerly 3M Cap-Seal) product. A range of one piece lining materials with a substrate choice of either unbleached virgin pulpwood or folding box board. Both conform to the stringent requirements of food approval bodies in a majority of countries. Can be used to line plastic and metal closures. The functionality of the AlphaSeal liner depends on the facing material applied to the pulpwood or box board substrate. Choices for facing material include polyester, PVDC, Saran, aluminum/foil/polyester, SA-66, univinyl, or aluminum foil. Depending on facing material selected, the AlphaSeal provides a general purpose sealing of bottles containing wet or dry products, solvents, weak acids and alkalines, and can provide a gas barrier.

A brown-colored glass used principally for beer, medicine and liquor containers. The color decreases the effect of some forms of light which would be injurious to the contents of the container.
> Ask about Amber Glass

Also ampoule, ampule, ampoul. A relatively small container made from a glass or plastic tube, the end of which is drawn into a stem and closed by fusion after filling. The bottom may be flat, convex or drawn out as required. Opening is achieved by breaking the stem.

> Ask about Animal Healthcare Products

A controlled temperature process in which glass is gradually cooled in ovens or lehrs to avoid the creation of stresses and strains within the glass due to natural or uneven cooling. The annealing temperature in glass is about 1000 degrees F.
> Ask about Anneal

A chemical substance that can be added to plastic resin to minimize or prevent the effects of oxygen attack on the plastic (e.g., yellowing or degradation). Such chemical attack by oxygen may render a plastic brittle or cause it to lose desired mechanical properties.
> Ask about Antioxidant

Corrugated board with embossed or chemically-treated surface, to increase coefficient of friction, so containers made from the treated board will produce a more stable pallet or unit load.
> Ask about Anti-Skid Corrugated

A substance applied to the surface of a plastic article, or incorporated in the plastic from which the article is to be made, so as to render the surface of the plastic less susceptible to accumulation of electrostatic charges which attract and hold fine dirt or dust on the surface. There are two types: (1) metallic devices, and (2) chemical additives, either internal or surface applied.
> Ask about Antistatic Agent

A container closure designed so that it may be used to apply the contents of the container, such as oil and grease spouts or daubers.
> Ask about Applicator Cap

Short glass rod 2 mm to 4 mm in diameter used in conjunction with an applicator cap. The end which enters the cap is cut square. The other end may have a variety of glazed finishes.

Items used to package aromatherapy products, including glass and aluminum bottles, vials, perfume samplers and candle holders.
> Ask about Aromatherapy Packaging

A technique for creating a shelf-stable container by placing a commercially sterile product into a commercially sterile container. The process involves sterilizing a product and its intended container (usually separately) and then bringing them together within a sterile environment for filling and sealing. The sealed container is designed to maintain a sterile product until the seal is broken. In addition, when packaged aseptically, the product does not require refrigeration until the package seal is broken. Used for drink boxes, wine (bag-in-box), tomato products and soy milk.
> Ask about Aseptic Packaging

A wide variety of assembly services such as collating, filling, gluing, labeling, bagging, shrink wrapping, bag sealing, blister sealing, display assembly, package assembly, inspection, and bulk mail preparation are available. Some companies follow strict anti-contamination procedures to ensure a clean pack.

A number obtained by adding the thickest wall section measurement of a container to the thinnest wall section and dividing by two. It does not describe the distribution of plastic material in a container.
> Ask about Average Wall Thickness

System of weights used in Great Britain and U.S. for the measure of goods other than gems, precious metals and drugs. Designated by "oz" or "oz av" and "lb" or "lb av". Sometimes, when a container is meant to hold a specific product such as honey or talcum powder, the bottle capacity is stated in auvoirdupois ounces rather than in fluid ounces. For example, a typical 1 lb. honey bottle holds 11 to 12 fluid ounces.
