What are the materials of barcode labels, and what are the uses of barcodes?

There are many different classifications of barcode labels:

Coated paper self-adhesive labels are generally used as information labels for medicines, food, wine, electrical appliances, beverages, etc.

2.Mirror coated paper self-adhesive label, multi-color product label, suitable for food, medicine, stationery, etc.

3.Aluminum foil self-adhesive label, suitable for high-end information labels for medicines, food, stationery, etc.

4.Matte writing paper, offset paper labels, multi-purpose labels, the most common in general life, used for information labels and barcode printing labels.

5.Thermal paper self-adhesive labels for marking** and as an informational label for retail supplies.

6.Fragile paper self-adhesive labels, used for electrical appliances and some mobile devices, medicines, etc. as anti-counterfeiting labels, label paper can not be reused after private.

However, the classification of barcode labels is not only the above, their materials are generally made of copper cardboard, mirror copper cardboard, polyethylene (PE), polypropylene (PP), polyester film (PET), vinyl (PVC) several processing and synthesis, each material has its own unique characteristics, generally if it is used for electrical appliances, there will be polyester film (PET) this material, because PET has a good scratch resistance, anti-fouling, high temperature resistance and other properties, Moreover, it has good degradable properties, and the impact on the environment will not be great, which is more environmentally friendly. If you need a label that is very resistant to high temperatures, it is not just the materials mentioned above, which are based on polyimide film and protected by high-temperature silicone pressure-sensitive adhesives. This label has excellent high temperature resistance and insulation, corrosion resistance, non-toxic and tasteless, and is harmless to the human body and the environment.

The barcode on the cigarette can mark the country of production of the cigarette, the manufacturer, the name of the product, the date of production, the category, the date and many other information, each kind of cigarette corresponds to a unique barcode, the barcode can be identified by the barcode reader, and it has a wide range of uses in commodity circulation.

The meaning of the product barcode number: The following takes the barcode 6936983800013 as an example, this barcode is divided into 4 parts, from left to right:

1. 1-3 digits: a total of 3 digits, corresponding to the barcode of 693, is one of China's national ** Xiangdong. (690--695 are all ** in Chinese mainland, distributed internationally).

2. 4-8 digits: a total of 5 digits, corresponding to the barcode of 69838, on behalf of the manufacturer, applied by the manufacturer, allocated by the state.

3. 9-12 digits: a total of 4 digits, corresponding to the barcode 0001, representing the goods in the factory, determined by the manufacturer.

Fourth, the 13th digit: a total of 1 digit, corresponding to the 3 of the barcode, is the check code, according to a certain algorithm, calculated by the first 12 digits and obtained.

One-dimensional code. A 1D barcode consists of a set of bars and empty symbols arranged according to certain rules.

Able to represent characters, numbers, symbols and other information; There are about 20 common kinds: such as EAN-13, CODE39, UPC-A, etc.

EAN series: the world's common commodity barcode developed by the International Article Number Association;

UPC series: American Unification ** Committee, the one-dimensional barcode used in the United States is composed of a set of bars and empty symbols arranged according to certain rules. Able to represent characters, numbers, symbols and other information; There are about two dozen common types:

Such as EAN-13, Code39, UPC-A, etc.; EAN series: the world's common commodity barcode developed by the International Article Number Association;

UPC series: American Unification Committee, in the United States and Canada;

Code39: Complete structural design, with certain error correction ability, widely used in industry, books and tickets;

Codebar: used in medical, logistics and other industries;

***。Due to the limited capacity of 1D codes, most applications require database support; So for this reason, on the basis of the one-dimensional code theory, *** appeared in the 90s of the last century; Not only can it store numbers, but it can also store information such as **, sound, fingerprint, etc.

QR code: Invented by the Japanese company DENSO, it is widely used because it can store Chinese characters and recognize quickly;

PDF417: Invented by American Symbol (now Motorola), widely used by American companies;

DataMatrix: Invented by idmatrix in the United States, the performance is stronger than PDF417.

Barcode label paper is divided into the following seven categories of only Huai files:

1. Matte writing paper and offset paper labels, used for information labels and barcode printing labels, especially suitable for high-speed laser printing, and also suitable for inkjet printing;

2. Coated paper self-adhesive labels, suitable for information labels of medicines, food, edible oils, wine, beverages, electrical appliances and stationery;

3. Mirror coated paper self-adhesive label, high-gloss label paper for high-grade multi-color product labels, suitable for information labels of medicines, edible oils, food, beverages, wine, stationery, and electrical appliances;

7. Thermal paper self-adhesive labels, suitable for ** marks and other retail purposes and other information labels.

Barcode label paper is divided into thermal labels, copperplate labels, PET labels, synthetic paper labels, jewelry tags, etc., according to the specifications of the printer, thermal labels (thermal labels do not use ribbons, thermal printing methods) and ordinary labels (generally refer to the labels with ribbons, thermal transfer printing methods).

In addition, the label is also divided into rolls and sheets, if it is printed with a barcode printer, use it into a roll. Single-sheet labels can be made with an ordinary laser printer. I can recommend it to you, go to Alibaba and search for Sunshine Wealth. Hope it helps. Thanks, hope!

The classification and use of self-adhesive labels are as follows.

1. One-dimensional barcode.

A 1D barcode only expresses information in one direction (usually horizontally), while in the vertical direction it does not express any information, and its certain height is usually for easy alignment of the reader.

2. Two-dimensional barcode.

A barcode that stores information in a two-dimensional space in both horizontal and vertical directions is called a 2-dimensional bar code.

Like 1D barcodes, 2D barcodes have many different encoding methods, or symbologies. In terms of the coding principles of these symbologies, they can generally be divided into the following three types.
