Glossary


C

Can Liner
Term used for garbage, trash or waste bags. It is used in industrial, institutional and medical applications. Can Liner Standard Colors are clear, black, white, gray, red, blue and yellow.

Case
The smallest shipping unit for poly bags containing multiple cartons.

Cast Film
Plastic film produced from synthetic resins (such as polyethylene) by the cast process. In this process, the molten resin is extruded through a slot die onto an internally cooled chill roll.

Co-extrusion
The simultaneous extrusion of two or more different thermoplastic resins into a sandwich-like film with clearly distinguishable individual layers. This involves a process where parts are blow-molded with walls containing two or more layers of different material. Coextrusion offers wide latitude for material selection and also allows the use of recycled materials. A material with good barrier properties, for example, can be used for the inside and outside surfaces of a blow molded bottle, while recycled material can be used for the internal layer. (Modern Plastics Encyclopedia 1995).

COF
The coefficient of friction is a measurement of "slipperiness" of plastic films and laminates. Measurements are usually done film surface to film surface. Measurements can be done to other surfaces as well, but not recommended because COF values can be distorted by variations in surface finishes and contamination on test surface.

Cold Seal
This is a term to describe pressure sensitive adhesive coating on plastic films or laminates that will allow the packages to be sealed by application of pressure (with no heat or with minimal heat).

Compostable
Compostable materials are capable of undergoing biological decomposition in a compost site, to the extent that they are not visually distinguishable and break down to carbon dioxide, water, inorganic compounds, and biomass, at a rate consistent with known compostable materials (e.g. cellulose). See also 'compostable plastic'.

Compostable plastic
A polymer is 'compostable' when it is biodegradable under composting conditions. The polymer must meet the following criteria: a) Break down under the action of microorganisms (bacteria, fungi, and algae); b) Total mineralization is obtained (conversion into CO2, H2O, inorganic compounds and biomass under aerobic conditions); c) The mineralization rate is compatible with the composting process and consistent with known compostable materials (e.g. cellulose).

Composting
The term used to describe the activity of breaking down plant and animal material using microorganisms under aerobic conditions. For successful composting there must be sufficient water and air to allow the microorganisms to break down the material, and the compost should reach and maintain a warm temperature.

Conversion
The term used to indicate converting plastic bags from a continuous roll to separate bags in a given configuration.

Cored Rolls
Bags or tubing is rolled on cardboard cylinders (looks similar to a roll of paper towels).

Coreless Rolls
Bags are rolled with perforations or are interleaved in a roll configuration.
