1. Material: Deep integration of technology and environmental protection
The core materials of Adhesive-Free Electrostatic Film label stickers are mainly PVC and PET films. These two materials have their own characteristics, giving the product diverse performance.
PVC film has excellent flexibility and can adapt to the surfaces of objects of different shapes. It is not easy to break even if it is bent or folded, and can meet the needs of personalized label production. Its good transparency makes the printed pattern more clear. Whether it is a colorful advertising label or a concise and clear product information label, it can achieve an ideal visual effect. At the same time, PVC film has good weather resistance. Under different climatic conditions, such as high temperature and humid environment, it can maintain stable physical properties for a long time, is not easy to age or deform, and ensures the long-term use effect of the label.
PET film is known for its high strength and high transparency. High strength makes it difficult to be torn and worn during transportation and use, ensuring the integrity of the label. High transparency makes the label seem to be integrated with the object being attached, without affecting the original appearance of the object, especially suitable for product packaging with high requirements for aesthetics. In addition, PET film has strong chemical stability and has a certain resistance to chemical substances such as acids and alkalis. In the application of chemical products and laboratory supplies labels, it can effectively prevent chemical erosion and maintain the integrity of label information.
In addition to PVC and PET films, special coatings are added to the surface of non-adhesive electrostatic film label stickers. On the one hand, the coating enhances the electrostatic adsorption ability of the film, so that the label can be firmly attached to smooth surfaces such as glass, plastic, and metal, and is not easy to fall off; on the other hand, the coating plays a protective role, which can effectively block ultraviolet rays, prevent the film from fading due to light aging, isolate moisture, prevent the film from being deformed by moisture, and extend the service life of the label. At the same time, the coating improves the surface performance of the film, provides a better adhesion basis for the printing process, and enables the ink to adhere evenly, presenting a clearer and more durable printing effect.
2. Production process: a combination of precision technology and innovative concepts
The production process of non-adhesive electrostatic film label stickers is complex and delicate, and each link affects the final quality and performance of the product.
Raw material pretreatment is the basis for production. PVC or PET film must undergo strict quality inspection before entering the production line. Professional equipment is used to measure the physical indicators of the film, such as thickness, transparency, and tensile strength. Only materials that meet the standards can be put into production to ensure product quality from the source. At the same time, the film is cleaned to remove surface dust, impurities, and static electricity to prevent these factors from affecting subsequent printing, die-cutting, and other processes, ensuring smooth production.
The printing process determines the visual effect of the label. Non-adhesive electrostatic film label sticker printing often uses gravure printing, flexographic printing, and digital printing technology. Gravure printing has a thick ink layer, high color saturation, and stable printing quality. It is suitable for mass production of high-precision labels, such as high-end product packaging labels, which can present delicate patterns and texts. Flexographic printing uses environmentally friendly inks, has low costs, and has strong production flexibility. It is suitable for small and medium-sized batch production and personalized customization. The printing content and pattern can be quickly adjusted according to customer needs. Digital printing does not require plate making, can achieve fast on-demand printing, has strong processing capabilities for complex patterns and personalized text, can meet customers' diverse design needs, and is especially suitable for emergency orders and small batch customized label production.
The die-cutting process gives the label a specific shape. High-precision die-cutting equipment and molds can cut the printed film into various shapes, whether it is a regular square, circle, or irregular pattern, it can be accurately presented. During the die-cutting process, the edge of the label is processed to make it smooth and flat, avoid burrs and burrs, improve the texture and use experience of the label, and ensure that the label is not easily damaged in subsequent use.
Electrostatic treatment is a key process for glueless electrostatic film label stickers. Static electricity is applied to the surface of the film through special equipment to make the surface of the film charged and generate electrostatic adsorption force. The intensity and uniformity of electrostatic treatment are crucial to the effect of label pasting. The processing parameters need to be strictly controlled to ensure that each label has stable and reliable electrostatic adsorption performance, so as to achieve glueless pasting and firm pasting and easy tearing.
