Plastics based on resins composed principally of polymeric esters, in which the recurring ester groups are an integral part of the main polymer chain, and in which ester groups occur in most crosslinks that may be present between chains.
Its an interesting book that i read many years back. It talks about the familiar sayings and their meanings. This reminds me that for we packaging technologists, the life is not different. If I try to explain the meaning of book from packaging technologists' point of view, its: 1. Lock: Tamper evidence 2. Stock: Material options and availabillty Chhavi Goel 3. Barrel: Its the real container where the complete packagingChhavi Goel technology is built up So here in this article, now we will try to give you more meanings about the popular words in packaging and we also expect you to add your familiar packaging sayings here for the benefit of entire packaging community.
Computer-aided manufacturing (CAM)
This term implies the use of a computer and postprocessing or linking software (such as Smartcam or Mastercam) to manipulate and compile data into a machine language for a machine(s) to execute the desired function. Another definition is the use of computers to program, direct, and control production equipment.
GSM
It is an acronym standing for 'Grams per Square Meter'. It allows print buyers and print suppliers to know exactly about the quality of paper that is being ordered. Two ways of expressing grammage are commonly used:
- Expressed in grams per square meter (g/m2), paper density is also known as grammage. This is the measure used in most parts of the world.
- Expressed in terms of the mass (expressed as weight) per number of sheets, it is known as basis weight. The convention used in the United States and a few other countries using US paper sizes is pounds of a ream of 500 (or in some cases 1000) sheets of a given (raw, still uncut) basis size. Japanese paper is expressed as the weight in kg of 1,000 sheets.
Coextrusion
Coextrusion is the extrusion of multiple layers of material simultaneously. This type of extrusion utilizes two or more extruders to melt and deliver a steady volumetric throughput of different viscous plastics to a single extrusion head (die) which will extrude the materials in the desired form. This technology is used on any of the processes used for plastic film manufacturing (blown film, overjacketing, tubing, sheet). The layer thicknesses are controlled by the relative speeds and sizes of the individual extruders delivering the materials.
In many real-world scenarios, a single polymer cannot meet all demands for an application. Coextrusion allows for mediation of this problem, optimizing a wide range of properties such as oxygen permeability, strength, stiffness, and wear resistance
laser scoring
Use of high-energy narrow light beam to partially cut through a material in a straight line or shaped patterns. This process is used to provide an easy-opening feature to various types of flexible packaging materials.
Diatomaceous Earth
A substance consisting of the skeletons of billions of microscopic plankton, containing a high amount of silicon. A common paper filler, also used in ceramics, glazes and dynamite.
Alkyd plastics
Backing Liner
Edible Packaging
The packaging is made of an edible component which is a thin continuous layer of edible material formed on / placed on or between the food and food components. This packaging is an integral part of the eaten and can be eaten as a part of the whole food product. This could be in form of a coating or a film
Corrugated board
Corrugated board is formed by gluing one or more sheets of fluted corrugating medium ( the wavy paper in the middle) to one or more flat facing linerboard. Common types corrugated boards are: Single Face, Single wall, Double wall etc.

Definition of 'Consumer Packaged Goods-CPG'
Cost and Freight (C&F)
Term of sale signifying that the price invoiced or quoted by a seller for a shipment does not include insurance charges, but includes all expenses up to a named port of destination. In comparison, carriage paid to (CPT) terms include all transport charges (but not insurance) up to a named place (usually the buyer's warehouse) of destination. See also cost, insurance, freight (CIF).

Elemendorf test
A test for measuring the tearing resistance of paper, paperboard, tape, and other sheet materialsTest details and other parameters are available in standard - ASTM D1424 - 09(2013)
Comments
· Deaerator:
A deaerator is a device that is widely used for the removal of oxygen and other dissolved gases.The air is removed to prevent undesirable oxidative reactions of product. The Deaerator generally consists of a vessel in which the product is exposed to a vacuum on a continuous flow.
Fin Seal:
Fin seals are created when the inside edges of the substrate are bonded, leaving the seam standing out from the package, such as on potato chip bags.
Lap seal:
Lap seals are made when two layers of substrate overlap, forming a bond with no material standing out from the package.
VACUUM PACKAGING
It is a method of packaging that removes air from the package prior to sealing. This method involves (manually or automatically) placing items in a plastic film package, removing air from inside, and sealing the package.
Shrink films are sometimes used to have a tight fit to the contents. The intent of vacuum packaging is usually to remove oxygen from the container to extend the shelf life of foods and, with flexible package forms, to reduce the volume of the contents and package.

ANCHORAGE
A term for how well a coating sticks to the substrate. Poor anchorage can cause coating to easily rub off the substrate
TAMPER EVIDENT TECHNOLOGY
Tamper -Evident describes a device or process that makes unauthorized access to the protected object easily detected.
To make a pack tamper evident various processes are being used. Solutions may involve all phases of product's production, distribution, logistics, sale, and use. No single solution can be considered as "tamper proof". Often multiple levels of security need to be addressed to reduce the risk of tampering. It could happen through packaging, seals and closures, master-batch, labeling and so on
VIALS
A vial (also known as a phial or flacon) is a small glass or plastic vessel or bottle, often used to store medication as liquids, powders orcapsules.
Lenticular printing
This is a technology in which lenticular lenses (a technology that is also used for 3D displays) are used to produce printed images with an illusion of depth, or the ability to change or move as the image is viewed from different angles.
Examples of lenticular printing include flip and animation effects such as winking eyes, and modern advertising graphics that change their message depending on the viewing angle
AUTOMATION
A technique of making industrial machinery, a process, or a system operate in an independent or self-controlling manner. This is the generic definition of automation. With regard to packaging, this definition should be adjusted to reflect the objectives of packaging, as follows: Automation is controlling the packaging line by using the optimum technique to cause the process to operate at a steady state pace in a self-controlling manner. Note that these definitions say nothing about eliminating labor or guaranteeing profitability, but they both imply that automation will optimize labor and give the potential of profitability
