27 Coding and labelling of food packages

 

32.1 Introduction

 

The objective of foodstuff labelling is to guarantee that consumers have access to complete information on the content and composition of products, in order to protect their health and their interests. Other information may provide details on a particular aspect of the product, such as its origin or production method. Some foodstuffs, such as genetically modified organisms, allergenic foods, foods intended for infants or even various beverages, are also subject to specific regulations.

 

Labelling of certain non-food products must also contain particular information, in order to guarantee their safe use and allow consumers to exercise real choice. In addition, the packaging of foodstuffs must adhere to production criteria in order to avoid contaminating food products.

 

The nature of the labelling, the presentation of the foodstuff, and the publicity for it must not:

  • Mislead the consumer as to the characteristics, the properties or the effects of the foodstuff
  • Attribute to any food the property of preventing, treating or curing a human disease (with the exception of natural mineral waters and foodstuffs for particular nutritional uses for which specific provisions exist).
  • Information on foodstuffs must be precise, clear and easy to understand by the consumer.

 

32.2 Responsibilities of the Manufacturer

 

The manufacturer under whose name or business name the food is marketed or the importer is responsible for the information relating to the foodstuff. They must ensure the presence and accuracy of the information in accordance with the applicable food legislation and requirements of relevant national provisions.

 

32.2.1 Mandatory particulars

 

The mandatory particulars must be easy to understand and visible, clearly legible and, where appropriate, indelible. The height of the characters must be at least 1.2 mm (except for small-sized packaging or containers).

 

The mandatory particulars concern:

  • The name
  • The list of ingredients which are listed in descending order of weight and designated by their specific name
  • The substances causing allergies or intolerances (nuts, milk, mustard, fish, grains containing gluten, etc.)
  • The quantity of certain ingredients or categories of ingredients
  • The net quantity of the food
  • The date of minimum durability or the ‘use by’ date
  • Any special storage conditions and/or conditions of use
  • The name or business name and address of the food business operator or importer
  • The country of origin or place of provenance for certain types of meat, milk or where failure to indicate this might mislead the consumer
  • Instructions for use where it would be difficult to make appropriate use of the food in the absence of such instructions
  • For beverages containing more than 1.2 % by volume of alcohol, the actual alcoholic strength by volume
  • Nutritional declaration

 

The mandatory particulars concerning the name, net quantity and the alcoholic strength by volume shall appear in the same field of vision.

 

The mandatory particulars must be in language which is easy to understand by the consumer, and, if required, in several languages.

 

32.2.2 Omission of certain mandatory particulars

 

Specific provisions are provided for:

  • Glass bottles intended for re-use
  • Small-sized packaging
  • The nutritional labelling of foodstuffs
  • Beverages containing more than 1.2 % by volume of alcohol

 

32.2.3 Voluntary information

 

Information provided voluntarily must meet the following requirements:

  • it shall not mislead the consumer;
  • it shall not be ambiguous or misleading;

32.6 Bar Code

 

A bar code may be defined as a series of bars and spaces arranged according to the encodation rules of a particular specification in order to represent data. Its purpose is to represent information in a form that is machine-readable. Bar codes are read by scanning devices that are programmed to analyse the structure of the bars and spaces and transmit the encoded data in electronic format. These data can then be stored on a file or transmitted to a computer for processing. Techniques other than bar codes achieve the same objective: capturing automatically data encoded using a particular technology. These include optical character recognition, magnetic stripe, and radio-frequency identification. The concept of encoding and reading data automatically is called automatic data capture (ADC).

 

32.6.1 Benefits of Bar Codes

 

The main benefits of bar codes are speed and accuracy. Capturing data automatically by reading a bar code can be done in a fraction of a second, much faster than manual key entry. It is commonly agreed that an operator doing key entry makes one error for every 300 characters typed. Reading bar codes makes data capture almost error-free. The error rate depends on the type of bar code and equipment being used, but usually it is lower than one error per 1,000,000 readings.

 

32.6.2 Bar-Code Symbologies

 

A bar-code symbology is a set of rules describing the way bar and spaces have to be organized to encode data characters. Since the invention of the bar code concept in the United States in the late 1950s, hundreds of bar-code symbologies have been developed, but only a few of them are actually being used on a large scale.

 

Typically, a symbology is qualified as being discrete or continuous. In a discrete symbology, the spaces between symbol characters do not contain information because each character begins and ends with a bar. In a continuous symbology, there is no inter-character gap; that is, the final element of one symbol character abuts the first element of the next symbol character, and all the elements carry data contiguously. The most popular bar-code symbologies are briefly described below.

 

32.6.2.1 Code 39

 

Code 39 was launched in 1975. It is widely used for industrial applications. Code 39 is a discrete, variable length symbology encoding the 36 numeric and uppercase alpha characters (A–Z, 0–9) and seven special characters: space, dollar sign ($), percent (%), plus (+), minus (–), dot (.), and slash (/). A symbol character is composed of nine elements, five bars and four spaces. An element is either wide or narrow. There are three wide elements and six narrow elements in a symbol character. A Code 39 symbol begins with a start character and ends with a stop character. It can be read from the right to the left and from the left to the right.

 

32.6.2.2 ITF

 

Interleaved two of five (abbreviated ITF) has been found to be well adapted to the materials and printing conditions frequently used on fiber-board cases. It is a continuous symbology encoding only numeric digits. A pair of digits is represented by five bars and five spaces. One of the pair is represented by the dark bars and the other by the light bars, and the dark and light bars are interleaved. Because the digits are represented in pairs, the symbol can only encode even number of digits. In addition to the digit characters, there are two auxiliary characters used as guard bars at the beginning and at the end of the digit representation. The symbol is designed to be read bi-directionally by fixed or portable scanners.

 

32.6.2.3 Code 128

 

Code 128 was introduced in 1981 in response to the need for a compact alphanumeric code symbol that could be used to encode complex data. The fundamental requirement called for a symbology capable of being printed by existing data-processing printers. Code 128 uniquely addresses this need with the most compact, complete, alphanumeric linear symbology available. In addition, Code 128 has been designed with geometric features to improve scanner reading performance and to be self-checking.

 

32.6.2.4 EAN/UPC

 

EAN/UPC was developed in the late 1960s when researches were conducted in the United States to improve the efficiency of checkout operations in retail stores. EAN/UPC is a continuous symbology encoding fixed-length numeric digits. Several variants exist, known as EAN-13, UPC-A, EAN-8, and UPC-E. In addition, the symbology enables to encode two small symbols encoding two and five digits. These are called add-ons because the information they contain supplement the main symbols. A symbol character is composed of seven modules, two bars, and two spaces. A bar or a space is composed of one to four modules. An EAN/UPC symbol begins and ends with a guard pattern. In the EAN-13, UPC-A, and EAN-8 version, a center pattern separates the symbol into segments that can be read separately by a decoding equipment, thus making the symbol omnidirectionally readable. The EAN/UPC symbology is widely used to encode the identification number of consumer products.

 

32.6.2.5 PDF417

 

PDF417 is a two-dimensional, stacked bar-code symbology. In PDF417, the basic data unit or minimum segment containing interpretable data is called a code-word. Every code-word in the symbol is the exact same physical length, and each code-word can be divided into 17 equal modules. Within every code-word, there are four bars and four spaces. The minimum number of modules of any bar or space is one; the maximum is six. The PDF417 symbology defines 929 distinct code-words and supports 12 modes. Each mode specifies the meaning of the code-words. The standard modes are Extended Alpha Numeric Compaction Mode, Binary/ASCII Plus Mode, and Numeric Mode. The number of data characters that can be encoded in a PDF417 symbol depends on the mode being used. In the extended alphanumeric compaction mode, the maximum number of ASCII characters per symbol is 1850. In numeric mode, a symbol can encode a maximum of 2725 digits.

 

32.6.2.6 Data Matrix

 

Data Matrix is a two-dimensional matrix symbology that is made up of nominally square modules arranged within a perimeter finder pattern. Each Data Matrix symbol consists of data regions that contain nominally square modules set out in a regular array. The data region, or set of data regions and alignment patterns, is surrounded by a finder pattern, and this is in turn surrounded on all four sides by a quiet zone border. The number of data characters per symbol is up to 2335 alphanumeric characters or 3116 numeric only characters. Data Matrix Symbols are read by two-dimensional imaging scanners or vision systems. Most other scanners that are not two-dimensional imagers cannot read Data Matrix. Data Matrix Symbols are designed for use with applications that involve imaging scanners throughout the supply chain.

 

32.6.3 Applications

 

The bar-coding technology has gained wide acceptance in numerous applications. Today, virtually all packages, from the smallest units intended for sale to a consumer to the biggest transport units, bear one or several bar codes carrying their identification number and other data relevant to the parties shipping, carrying, or receiving goods.

 

Scanning at retail point of sale is a major application using bar-code technology. Millions of stores around the world have implemented scanning systems relying on the GS1 identification number and the associated EAN/UPC bar-code symbol.

 

A rapidly growing field of applications using bar-coding technologies lies within the supply chains. Goods ready for shipment by a supplier are packed, and each package is numbered and bar-coded with a unique number. Before the physical delivery of the merchandise, the supplier sends an electronic message to the delivery point, advising about the arrival of the goods. This electronic message contains the unique identification number of each package and the description of its contents.

 

32.6.4 Printing Bar Codes

Virtually any printing technology can be used to print bar codes, provided that it is accurate enough to achieve the right level of required quality. The printing processes fall into two categories: commercial and on-site. The choice between these two approaches is determined by the nature of the information to be encoded and the number of codes to be printed. Typically, if the information is static (e.g., the identification number of a product to be placed on a package) and if the number of codes to be printed is large, the traditional commercial method using film masters is appropriate. If the information is variable (i.e., different for each item or short series of items or if the quantity required is small), then on-site printing processes should be used.
