When we ship the machine, the client always asked us to stick a shipping mark onto the wooden case. Some people use copy A4 paper to print, some people use adhesive paper to print. When we buy some new goods, there is a sticker on the outside of the package box. Even buy a new tire for our car, there is a paper sticker on it. Wow, there seem so many paper stickers in our daily life packaging. Today we are going to talk about the “paper sticker” and the cutting machine that possibly working with it.
What is Adhesive Paper?
Self-adhesive paper is a kind of paper that is made of paper, film, or special materials, coated with adhesive on the back, and coated with silicon protective paper as the base paper.
The Structure of the Self-adhesive Paper
* Top coating- face coating, generally used to improve printing performance.
* Facestock- surface materials (comprehensive selection according to customer requirements, actual stickers, and use environment).
* Primer-back coating is usually used to improve the adhesion between the glue and the back of the surface material.
* Adhesive- glue (usually used in durable goods such as electronic products, cars, tools, etc., which have high adhesion and weather resistance; hot melt glue has a high viscosity, low price, wide use, but poor weather resistance and heat resistance; water glue is environmentally friendly, good processability, usually used in food, medicine, daily chemical, etc.).
* Release coating- release coating, composed of silicone oil (water separation and UV curing, Dow corning is the largest supplier), reduces the stickiness between the glue and the base paper, and enables the glue to be stripped from the base paper when labeling.
* Release liner- release layer, mainly made of transparent PET film or paper (transparent Gracindi paper, opaque yellow base paper, CCK (coated clay paper, etc.). Only transparent base paper can be used for automatic labeling.
* ABC Coating- is mainly used to prevent the glue from penetrating the white surface of the base paper and to avoid adhesion between the back of the base paper and the surface material when the label is rolled up into a large roll.

The Adhesive Paper Market Price in China
The price is measure by square meter or roll. Below pictures are the price for B2B platform for reference:
Adhesive Paper Roll Cross-cutting Machine
Working Theory
1.The main contents are as follows: 1. The paper slitting machine should cut the whole roll or the whole raw material with a fixed length, and use the fixed-length slitting control.
2. The slitting length can be set continuously. If there is an error in the actual slitting length, it is easy to be calibrated by setting parameters.
3. The slitting control of the paper slitter is divided into static and dynamic slitting: accurately stop the machine when the set length reaches, then static slitting processing, and restart the operation after slitting; when the set length arrives, the paper slitting machine sends out slitting signal without stopping, and the slitting machine cuts dynamically in the process of material movement.
Attention Points in the Operation of Self-adhesive Paper Cutting Machine
1. Before use, the machine should check whether the working position is properly adjusted, the lubricating parts that need to be lubricated should be filled with lubricating grease in advance, and at the same time should insist on whether the cutting tool on the tape slitting machine is sharp.
2. Before working, we should also check whether the machine is abnormal and enter the order for processing into the computer for inspection in advance.
3. Before the self-adhesive paper slitting machine is turned on, the operator should ensure that there is no other personnel around it, to avoid accidental injury to other personnel.
4. Ensure the normal voltage, current, and hydraulic pressure before starting up, to ensure the safe and effective operation of the equipment.
5. During the operation of the self-adhesive paper slitting machine, to avoid involving the hand in causing personal injury, we should pay attention not to touch the film roll or roll core in operation.
6. When operating the self-adhesive paper slitting machine, you should be careful not to use knives or hard objects to scratch or cut each roll core.
7. After the self-adhesive paper slitting machine is put into work, the best working state of the equipment should be adjusted in time according to the production situation to ensure that the indentation of the cutting machine is moderate, the cutting is burr-free, and the trimming position on both sides is suitable.
8. The equipment should be cleaned and maintained regularly when it is not in use to ensure that it can be used directly next time. For example, it is necessary to inject butter every half a year when the transmission chain and gears are short of oil; the lubrication of the reducer, the lubrication of the bushing and the shaft on the coiling shaft, the lubrication of the gas source processor, or regularly check whether the screws are loose or not, it should be noted that the belt slitter should not use corrosive chemicals to wipe the embossed wheel, rubber wheel, and coiler during maintenance.

Adhesive Paper Q&A
Can an ordinary printer print A4 self-adhesive tape?
Ordinary laser printers and inkjet printers can print A4 self-adhesive tape, but there are many precautions: 1. Print properties of traditional Chinese medicine are set to self-adhesive or thick paper mode. 2. Laser printers and inkjet printers are respectively suitable for their inkjet printing paper, but the matte adhesive tape is recommended. 3. The glue-overflowing printing paper will reduce the drum or belt of the laser printer and the inkjet printer will reduce the service life of the nozzle.
What are the differences between the dry sticker and the water sticker?
The difference between sticker dry sticker and a water sticker is that it is posted on the wall or the glass. In general, when posting post-it stickers on the wall, you can only use the “dry sticker method”, while in the glass surface construction, it is usually recommended to use the “water sticker method”.
How long can the self-adhesive paper be stored?
The best storage condition is 23 ℃ and 50% humidity. In this environment, the self-adhesive material can be stored for 1 year, after more than 1 year, it is necessary to check the stickiness and peeling degree of the paper surface material. It is recommended that plastic film sealed packaging, printed label packaging should be layered and stacked, not overweight, to prevent glue penetration and adhesion, to prevent direct sunlight.
Is self-adhesive tape harmful?
It is recommended that the plastic film be sealed and packaged. After printing, the labels should be layered and stacked, not overweight, to prevent glue penetration and adhesion, and to prevent direct sunlight.
What kind of rubbish does self-adhesive paper belong to?
Self-adhesive tape belongs to dry rubbish / other rubbish. Dry rubbish: other domestic wastes except for hazardous garbage, recyclables, and wet garbage. Common dry trash / other rubbish are jars, old bathtubs, cups, walnuts, disposable chopsticks, broken flowerpots, wooden combs, dirty clothes, basketball, toilet paper, ceramic bowls, garbage bags, tiles, brooms, etc.
How to tear the adhesive tape clean?
It’s hot. We can directly use a lighter or a hairdryer to heat the sticker to make the glue dissolve. When the label is a little hot, it’s easy to take it off.
Encounter water. If there is no lighter, we can soak these in warm water for a while and wait for the sticker to soften thoroughly. The effect is also good.
Alcohol, essential oil. Alcohol, wind oil essence and so on is also very suitable, with alcohol coated on the surface of the self-adhesive label, feel that the self-adhesive has been softened and gently torn, it can completely fall off.
What are the reasons for the raised edges of self-adhesive labels?
Glue viscosity is too weak: suitable glue material should be selected.
The pressure of the pressing wheel of the labeling machine is not enough: the reason and the solution areas above.
Label surface material: when selecting label surface material, we should consider whether the labeling object is a plane or a surface, large diameter or small diameter, a single surface or a sphere, a rigid body or a compressible deformation, these indicators are directly related to the Improper selection of adhesive: when choosing a self-adhesive adhesive, printing recommends that you first determine whether the adhesive required for the self-adhesive label is permanent or removable, whether it is pasted at one time or can be re-pasted.
Poor control of film tension: the label with the correct coating is removed from the base paper, and the label is not curled or labeled. After the label with too tight tension is removed from the base paper, the label is reversed, which leads to the phenomenon of label edge degumming and warping after labeling.
The shape design of the bottle body is unreasonable: the reasonable design should be that the surface within the labeling range of the bottle body is flat (mainly in the design of the flat round bottle body), but if the surface is partially spherical within the labeling range, the labeling area is larger when using paper labels, and the lower end of the labeling is easy to wrinkle on both sides.
This is Zoe, the above knowledge is just the tip of the iceberg, but they demonstrate how helpful the adhesive paper is. Then it could transform value chains and operations. To get adhesive paper business boom day by day.
