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.
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.
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 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
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.
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.
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 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.
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).
Freight on board (FOB)
A test for measuring the tearing resistance of paper, paperboard, tape, and other sheet materials
Test details and other parameters are available in standard - ASTM D1424 - 09(2013)
