Types and advantages of commonly used protective films for die-cutting

The categories and advantages of commonly used protective films in die-cutting are widely used in modern industrial production, and die-cutting technology is widely used in industries such as electronics, automobiles, and packaging. In order to ensure that the product is not affected by the external environment during processing and transportation, various types of protective films are usually used in the die-cutting process. This article will introduce several common die cutting protective films and their respective advantages and characteristics. PET (polyethylene terephthalate) protective film characteristics: PET material has excellent weather resistance and UV resistance, suitable for outdoor application scenarios. Good mechanical properties and high adhesion enable it to withstand a certain degree of pressure and temperature changes. High transparency, does not affect the appearance of the protected product. Advantages: Anti scratch: Effectively prevent surface scratches and maintain product appearance. Waterproof and dustproof: Form a barrier to prevent moisture and dust from entering the interior of the product. Easy to peel off: It is not easy to leave residue on the surface of the object during peeling, reducing cleaning workload. Applicable industries: consumer electronics, solar panels, etc. Characteristics of PE (polyethylene) protective film: PE material is soft and elastic, suitable for laminating products with curved or complex shapes. It has good adhesion to ink and is commonly used for surface protection of printed materials. Low cost, suitable for large-scale production and applications that require cost-effective solutions. Advantages: Good flexibility: Adaptable to different surface curvatures and bends. Good barrier: prevents direct contact between moisture and other pollutants with the product. Environmentally friendly and non-toxic: compliant with RoHS standards, harmless to human health. Applicable industries: household appliances, building materials decoration, etc. OCA (Optical Tape) Characteristics: OCA is a specially designed double-sided coating film mainly used to achieve seamless full screen coverage and pasting between two planes. High light transmittance, which does not affect the display effect, suitable for fields such as touch screen assembly. Not sensitive to water vapor and can be used in high-temperature environments. Advantage: Ultra thin design: With a thickness of only a few micrometers, its presence is almost imperceptible. Automatic correction function: able to adjust position deviation on its own, improving fitting accuracy and efficiency. Strong durability: can withstand frequent touch and use, extending the service life of the device. Applicable industries: Mobile terminal devices such as smartphones and tablets. PVC (polyvinyl chloride) protective film characteristics: PVC material has excellent impact resistance and wear resistance, suitable for rough environments. Rich in color, it can be customized for dyeing to meet the needs of different customers. The price is relatively low, suitable for users with limited budgets. Advantages: Anti wear: Provides effective physical protection and reduces wear and tear caused by daily use. Anti corrosion: It has a certain resistance to chemicals and protects products from liquid erosion. Easy to install: No special tools are required to quickly complete the fitting operation. Applicable industries: Building hardware, kitchen and bathroom products, etc. The choice of appropriate protective film depends on the specific usage environment and product characteristics. Each type of protective film has its unique advantages and applicability, so reasonable choices should be made based on specific situations in practical applications. With the development of technology and the continuous emergence of new materials, more high-performance protective film products will emerge in the future, bringing more possibilities for the application of the die-cutting industry.
