The market of plastic labels is expanding constantly, and the market share of trademarks, stickers and signs is increasing day by day. Compared with other labels, plastic labels have the following characteristics in use.

1. Widely used. Not only in food and beverage, miscellaneous goods for daily use, household appliances, stationery, etc., but also in the price label of commodities in circulation, clothing, textiles, medicine, cosmetics, etc.

2. Easy to paste. Glue, paste and other adhesives are not needed, which is very convenient and has no pollution to the appearance of goods.

3. Durability. Strong adhesion, flexible adhesion, heat resistance and moisture resistance, and difficult aging. These are the characteristics of plastic labels.

Because of the various characteristics of plastic label, it was quickly accepted and applied by the public as soon as it came out, replacing the traditional trademark, and it has become an indispensable logo decoration for goods.

In the daily chemical label self-adhesive market, although the market share of paper labels is as high as 75%, in recent years, the heat transfer film labels also show a high growth trend. For heat transfer film materials, good printability is absolutely necessary, but the commonly used PE and PP films can not meet the requirements. In order to ensure that there are few problems or no problems in the printing process of this kind of label materials, it is very important to change the film surface properties.

There are many methods that can be used to modify the surface of thin films, including corona pretreatment, plasma pretreatment, flame pretreatment, chemical pretreatment/fluorination and coating pretreatment. Among them, corona pretreatment and coating pretreatment are the most commonly used surface treatment methods in printing industry.

Corona pretreatment is realized by high frequency and high voltage discharge of electrodes. After corona pretreatment, the surface energy of PP film can be increased to nearly 50mN/m, but this effect is short, because the following processes counteract the effect of corona pretreatment: polar functional groups rotate inward in plastic film polymer; The functional groups react and lose polarity; Additives in the film migrate to the surface and cover polar functional groups. The longer the film material is stored, the more serious this situation is, so corona pretreatment must be carried out again before printing.

The effect of corona pretreatment will be different with different materials of heat transfer film. In addition, the additives in the film and the aging of the material will also have a certain impact on the corona treatment effect. That is to say, when corona treating aging films containing more additives (such as lubricants), it will be difficult to obtain sufficiently high surface energy due to the barrier of additives migrating to the film surface.

In cold environment, the viscosity of BOPP labels decreases with the decrease of temperature. The conditions that BOPP labels often encounter in winter, such as non-stick glue, Fei Biao, dropping labels and so on, are all related to temperature.

1. Storage environment temperature

The storage environment temperature of BOPP label should not be too low. Self-adhesive materials placed outdoors or in cold environment can easily cause frostbite of materials, especially glue. If it is not properly restored, the viscosity and processability of self-adhesive will be lost or lost.

2. Processing environment temperature

Processing environment temperature is very important for materials to be processed smoothly. If the temperature is too low, after the viscosity of the material decreases, there will be poor printing, die-cutting Fei Biao, Fei Biao and falling marks in the processing, which will affect the smooth processing of the material.

3. Labeling ambient temperature

The labeling environment temperature should meet the product requirements. First of all, it is necessary to introduce relevant concepts: the lowest labeling temperature of self-adhesive products refers to the lowest environmental temperature at which labeling operation can be carried out.

4. Label preset processing

Tag presetting is very important in cold areas. If the temperature of the label itself is low or even frostbite due to the unsatisfactory transportation and storage conditions, although the labeling environment temperature meets the requirements, the viscosity and processability of the self-adhesive will also be affected because it cannot be recovered in time.

5. Use temperature range

After labeling, it usually takes a period of time (usually 24 hours) for the viscosity of self-adhesive label materials to gradually reach the maximum value. It is not advisable to put containers or products that have just been labeled into an environment with large temperature difference immediately (even if the environment meets the use temperature range of self-adhesive materials).

6. Surface cleaning

When labeling, attention should also be paid to the pressure control of labeling and the cleaning of the surface to be pasted. A suitable labeling pressure can not only ensure the pressure sensitive characteristics of pressure sensitive self-adhesive labels, but also discharge the air between the labels and the surface to be pasted. Therefore, the label is firmly and flat. Cleanliness of the pasted surface is also an important factor to ensure the viscosity and flatness of the label after pasting.

In fact, shrink sleeve labels are widely used, for example, shrink sleeve labels can be seen in many industries such as medicine, food, cultural products and so on, which can well illustrate that shrink sleeve labels are widely used.

Shrink sleeve labels have the advantages of no glue, no paste, no dipping in water, no pollution, saving labeling time, etc. They have a wide application range and are convenient and fast. All kinds of shrink sleeve labels can be applied to materials that ordinary paper labels cannot do. It can be said that shrink sleeve labels are universal labels. Compared with traditional printing, shrink sleeve label printing is very different. Shrink sleeve labels are usually printed and processed on a label linkage machine, and multiple processes are completed at one time, such as graphic printing, die cutting, waste removal, cutting and rewinding.

Shrink sleeve labels use advanced multi-color product labels. It is usually applied to information labels of drugs, food, electrical appliances, cultural goods and other items.

Label printing can be said to exist in all aspects of our life. The existence of label printing from product labels to price stickers, from instructions to brand promotion has brought a lot of convenience to our life and has also enabled print labels supplier to see business opportunities. However, it should be noted that label printing technology requires label materials. In order to achieve a good printing effect, label materials must be selected from multiple perspectives, so as to achieve an ideal label printing effect.

First of all, it is selected according to the characteristics of the substrate. The printed label and the carrier are used together. In order to make the two fit perfectly, it is necessary to consider the substrate characteristics of the carrier and the respective characteristics of the product or packaging material. Due to their different compositions and different ability to combine with tag limbs, special attention should be paid during production.

Secondly, different types of materials are selected according to different classifications and respective characteristics of label printing labels, and transparency, tearing property, softness and the like need to be considered. For example, if it is used as a commodity label in supermarkets, paper label materials with strong adhesiveness should be selected. The labels on the goods in the freezer or refrigerator should be low-temperature resistant flour and acrylic adhesive. On the contrary, the labels on heating appliances such as motors should be made of high-temperature resistant PET material.

Finally, according to the environment to choose. For example, the storage environment and transportation environment of products should consider temperature and humidity. Temperature difference range is indoor or outdoor, whether there is direct sunlight, etc.

As people's living conditions are getting better and better, they are becoming more and more fastidious about what to eat. Health preservation and health are in vogue now. Therefore, plastic labels will be observed first before deciding whether to buy food in supermarkets.

The plastic labels shall clearly state the name, specification, net content, date of production, ingredients or ingredients list, name, address, contact information, shelf life, product standard code, storage conditions, common name of food additives used in national standards, production license number, and other matters stipulated by laws and regulations.

In daily life, there are always some unscrupulous merchants who cheat on plastic labels in order to obtain high profits: for example, some foods have high fat content, so merchants must show zero fat on them to impress people! This is very harmful to our health!

Plastic labels should be clear, clear and easy to identify. Now more and more strict plastic labels tell us: the food you eat may be getting unhealthy!

Using advanced printing technology and high-quality label materials, a variety of specially printed labels have been developed, including sticker reverse printing, backing paper printing, local gluing, special die cutting, code anti-counterfeiting, ink discoloration, nuclear track anti-counterfeiting, etc. Products are widely used in medicine, food, daily chemicals, electronics, petrochemical, jewelry, logistics and other industries.

Packaging should be used for circulating products in all trades and industries. What is the concept and function of packaging for big brand companies in the consumer goods industry? What are the functions of the print labels supplier on product packaging?

The label, which carries complete product information and display effect, also shows the temperament and personality of the product itself and should be said to be the finishing touch to the product packaging. One of the requirements for labels on finished product packaging is the quality requirement, i.e. no wrinkles, no bubbles, no scratches, no burrs, etc., accurate printing overprint, no overlapping, no ink leakage, no ink impurities, etc., good adhesion and no warpage. Another is the new requirement of the information age, that is, to carry more product introduction materials, display them in the form of two-dimensional codes, and connect to more brand stories behind products, similar product introductions and other promotional information; Another is AR technology, that is, by scanning the product label and playing the previously recorded video photo files, consumers can feel personally involved, integrate into the brand, and improve their sense of scene.

The higher the price or the higher the cost, the better the label is, but the better it is to conform to the brand positioning and highlight the brand personality. Of course, the choice of labels is also constrained by the profit margin index of products, and it is necessary to seek the balance of materials, technology and design within the limited cost space. However, in the future, labels will be the collection carrier of big data. RFID technology can be used to integrate consumer usage data and logistics data from all channels, thus becoming an important resource for brand companies and facilitating further development of new markets.
