The problems to be noticed of self adhesive stickers label printing

The self adhesive stickers label printing need to be aware of problems:
Small self adhesive label, and many times is the important of corporate image, brand, to reflect the quality of the products, play an important role to cause consumers the purchase desire.
Adhesive processing is done through online way, and its quality control is a comprehensive problem, need from the choice of materials, equipment configuration and control and process line, and considering the set of implementation, can according to label products in terms of the user, the application of which to improve the quality of the label.
self-adhesive label
When choosing raw material, choose high quality as well as various physical and chemical indexes of qualified adhesive material, failed not because the material price is low, and use. Inferior quality of the raw material itself is not stable, and more have a chance to lead to equipment can't normal processing, and human waste of resources, will cause losses to the human resources, lose customers. Therefore, in terms of the selection of raw materials, materials with strict standards. You can rest assured to buy and place the order.
How to avoid the back glue film adhesive printing labels process
1. For cylinder bottle, especially less than 30 mm in diameter, be careful to choose material.
2. If the label size is too big or too small, should be pay attention to proceed actual experiment.
3. If the post content is irregular surface spherical, even for the label material type, thickness and adhesive has a specific consideration.
4. Some rough surface such as corrugated carton will affect the labeling, light oil also have an impact on the surface of the corrugated carton.
5. Automatic labeling machine, if necessary can proceed labeling experiment.
6. Even if the tag is labeling at room temperature, pay attention to the export experience in transit and the use of high temperature.
7. More oil or water environment will affect the adhesive stickers properties, such as tag target environment and temperature should be paid attention to.
8. Soft PVC surface sometimes has a plasticizer, pay special attention to selecting the appropriate adhesive.
Printing process
Most of them adopt the same process. Self-adhesive printing process is mainly done on the label machine one-time meaning that a machine can complete label printing a number of different processes.

The Information of Rigid PVC Packaging Film

PVC (polyvinyl chloride) chemical and physical properties. Rigid PVC is one of the most widely used plastic material. PVC material is a kind of non-crystalline materials. PVC material in used actually often add stabilizer, lubricant, auxiliary processing agent, pigment, impact resistant agent and other additives. PVC material have no flammability, high strength, good resistance to climate change and the geometric stability. PVC of oxidant, reductant and strong acid has the very strong resistance. However it can be strong oxidizing acid such as sulfuric acid, nitric acid corrosion and also does not apply to the occasion of contact with the aromatic hydrocarbons, chlorinated hydrocarbons. PVC rigid sheet melting temperature during processing is a very important process parameters, if the parameters will lead to improper material decomposition problem. The flow characteristics of PVC is rather poor, its technological range is very narrow. Especially big molecular weight of PVC material is more difficult to process (this material is usually to add lubricant to improve flow characteristics), so usually use the small molecular weight of PVC material rigid PVC film. PVC shrinkage rate is low, it is generally 0.2 ~ 0.6%.
PVC Sheets for thermoform blisters packaging
The process conditions of injection moulds
Dry processing: usually do not need to be dry processing.
Melting temperature: 185 ~ 205 c
Mold temperature: 20 ~ 50 c
Injection pressure: can be reach to 1500 bar
The holding pressure: can be reach to 1000 bar
Injection speed: to avoid material degradation, generally want to use reasonably the injection speed.
Runner and gate: all regular gate can be used. If processing small parts, it would be better to use needle point gate or dive into the gate; For thicker components rigid film, it is better to use the fan gate. Pinpoint gate or dive into the gate of minimum diameter should be 1 mm; The thickness of the fan gate cannot be less than 1 mm.

Basic Knowledge of The Masterbatch

The full name of masterbatch is color masterbatch, also known as color pigment. It is a special colorant for new type of polymer materials, which is composed of pigments or dyes, carrier and additives these three basic elements, is take extraordinary amount of pigments or dyes evenly attached in resin to obtained aggregation. It can be seen as pigment concentrate, so its coloring is higher than the pigment itself. The masterbatch is mainly used in plastics, to achieve the desired color effect in the plastic or rubber products.
The commonly used methods of the classification of Plastic Masterbatch is as following:
A. By carrier classification: such as PE masterbatch, PP masterbatch, ABS masterbatch, PVC masterbatch, EVA masterbatch, etc.
White Color Masterbatch
B. By Application : such as injection masterbatch, blowing masterbatch, spinning, masterbatch, etc., And each type can be divided into different levels, such as:
1. Advanced Injection Masterbatch: Used for cosmetics packaging, toys, electrical shell and other advanced products.
2. Ordinary Injection Masterbatch:Used for general daily plastic products, industrial containers, etc.
3. Advanced Blown Film Masterbatch: Used for blow molding of ultra-thin products coloring.
4. Ordinary Blown film Masterbatch: Used for blow molding of general packaging bags, woven bags coloring.
5. Spinning Masterbatch: Used for textile fiber spinning coloring, thin pigment particles, high concentration, high coloring, heat resistance, good light fastness.
6. Low Class Masterbatch: Used in the manafucture of low -level products that less demanding on the color, such as trash can, low-level containers, etc.
7. Special Masterbatch: is according to user specified for products of plastic varieties, use the same plastic as the carrier of masterbatch.Such as PP masterbatch, ABS pigment respectively choose PP, ABS as a carrier.
8. Universal Masterbatch: Also use some kind of resin(often low melting point PE) as a carrier, but it can be applied to coloring other resin in addition the its carrier resin. Universal masterbatch is relatively simple, but the disadvantages are more, recommends that users use Special Masterbatch. Special Masterbatch heat levels are generally compatible with the plastic products, at normal temperature , can be safely used. Only under the following conditions can cause varying degrees of discoloration , one temperature exceeds the normal range , another stop too long.
Why use masterbatch instead of toner?
1. In many cases ,the plastic products manufacturers choose toner when matching color that is not the most economical choice. And not familiar with the toner, it is very common that resulting in waste of manpower and materials when repeated color trial,This problem does not exist when using masterbatch.
2. The class of the products made by masterbatch coloring is completely different with the one by toner coloring , and the price of the former should be higher. The higher parts is some higher than the increase in the cost of using masterbatch. So the masterbatch can create “profits” instead. From this perspective , in some cases , the use of masterbatch coloring dye coloring is more economic than using toner.

The choice of adhesive sticker

The adhesive sticker label printing have higher requirements on process and printing equipment, so when choosing the adhesive sticker should pay attention to the following points:
1. According to the labeling of the object type, the scale, quality, characteristics on the surface of the paste, the using environment and the user's requirements and other comprehensive consideration. If you want to use good transparency polypropylene adhesive printing labels on the label made of transparent bottles can produce no labels of fashionable feeling, can enhance the grade of the goods, stimulate consumer purchasing desire. And polyvinyl chloride (PVC) film flexibility, contractility, opaque, processing property and labeling features are very good, and colourful, have the function of the promotion of goods.
self-adhesive sticker
2. Film class the adhesive sticker surface must be smooth and uniform compact, density, colour and lustre is consistent, pervious to light and to ensure the film absorbing ink evenly, with the printing quality of color difference is small.
3. The thickness of the adhesive sticker wants uniformity, intensity index to be qualified. Printing process of printing pressure associated with adhesive thickness, if the thickness, the printing pressure is uneven, lead to label print handwriting or ink has deep have shallow. If poor strength of thin film, printing film tension, it is difficult to control in the process of the die cutting and produce a great impact on the waste discharge.
4. The adhesive sticker to level off some, rewinding tension is uniform. Good flatness, printing to the correct delivery, running, alignment, and winding. The rewinding tension of the film is uniform properly, such as tension is too small, thin film base material is flabby, lateral misregister; Tension is too large, such as base material transverse shrinkage, color is not stable, also hard to normal printing.
5. Film class the self adhesive stickers also has corrosion resistance, ageing resistance, do not fade, the characteristics of shrinkage, low expansion ratio. Such as poor corrosion resistance, easy aging and fading, the label is not made of durable, will also affect the product sales and use. If the contraction and expansion ratio is larger, the not only influence the printing overprint precision, also can make the label deformation in use process, affect product sales and use. Especially high-grade goods, should try to avoid the goods being expired, and tag has the embarrassing situation of aging (including plastic tag aging and fading of ink). Necessary to carry on the resistance to aging experiment to deal with plastic or label, testing its performance.
6. The choose and buy the adhesive sticker is in the period of validity, maintain good viscosity.
