Basa renzvimbo yekudhinda ndeyekugamuchira inki, kuumbwa kwemavara emifananidzo uye zvinyorwa; chikamu chepakati kutsigira nzvimbo yekudhinda, kupa zvinhu zvakakwana kuoma uye pachena, mukudhinda uye kupisa kwepamusoro pasi pechiito che deformation, kuve nechokwadi chekudhindisa kwakaringana. Iyo adhesive layer ichanyungudika pasi pechiito chekushisa kwakanyanya, making the label material and the plastic container become an integral whole, ensuring that the label and the plastic bottle firmly stick together.
Printed surface materials generally have three: PE, Bopp and PE + PP. Since most plastic containers are currently made of PE material, the use of PE in-mold labels is more conducive to recycling, as they are homogeneous materials. In the production of in-mold labels, in order to improve the ink-affinity printing surface materials, generally need to coat surface coating or corona discharge method to improve the surface energy.
There are two kinds of structures on the surface of the adhesive layer: planar meshfree structure and reticulated structure. The former is used in direct contact with the blank, natural exhaust, suitable for small area labels. The latter imprints the reticulated structure on the surface, and when in use, the gas is vented through the reticulated exhaust passage, thus avoiding the production of air bubbles. The adhesive layer also has the antistatic property to prevent double sheets when printing; in addition, it also has the sliding property to ensure the smooth separation of labels, making the printing process smoothly.

Ⅳ The way of Sino IML
Die-cutting into the label, the use of a manipulator piece by piece into the cavity, the use of extrusion plastic temperature and suction air pressure, the label and plastic bottles melt into one. Zvino, Sino IML has two ways: vacuum suction mode and electrostatic mode.
The vacuum mode is the most common and widely used method at present. Plastic packaging products companies can add in the original mold vacuum micro-hole, no special equipment, low-cost, very good use effect, and not easy to detect the vacuum mark, the technology is now very mature.
The most advantage of this technology is that it does not need to reform the original blow molding equipment, but at present, there is no successful case in our country. The electrostatic model has special requirements for Sino IML technology, equipment and physical properties of labels:
1) a high voltage electrostatic discharge (ESD) system must be added to the device to uniformly apply sufficient electrostatic charge to the label for a short period of time and attach the label to the blow molding cavity at zero potential through a robotic arm.
2) the electrostatic elimination system must be added to the equipment to eliminate the residual static electricity after each labeling and to avoid its influence on the electric control system of the Sino IML machine and the phenomenon of label adhesion caused by static electricity.
3) the appropriate label substrate and printing ink must be used.
