The new trends of PET release printed films in terms of customization and high-performance features are as follows:
Customization Trends
Diverse Design Customization:
Personalized Patterns and Graphics: With the development of digital printing technology, it is possible to print various personalized patterns and graphics on PET release films. For example, in the packaging of personalized gifts and customized pet products, it is allowed to print patterns related to the characteristics of the gift or the image of the pet.
Variable Data Printing: In the fields of labels and packaging, variable data printing is gradually increasing. Information such as batch numbers, barcodes, QR codes and dates can be printed as needed to meet the needs of product traceability and personalized identification.
Size and Shape Customization:
Non-standard Size Products: Customers have different requirements for the width, length and thickness of PET release printed films1. Manufacturers are capable of providing non-standard size products to meet specific application scenarios, such as the needs of special-shaped product packaging and some special electronic components.
Customized Shapes: Besides the conventional rectangular shapes, PET release films can also be processed into special shapes like circles, ellipses and irregular polygons to meet the individual needs of different products and designs.
Function Customization:
Special Surface Treatment: According to different application requirements, the surface of PET release printed films can be treated with functions such as anti-fouling, anti-scratch and anti-static. For example, in the electronics industry, anti-static PET release films are used to protect electronic components from static electricity damage.
Customized Release Force: By adjusting the formulation of the release agent and the production process, the release force of the PET release film can be accurately controlled to meet the requirements of different adhesive products, such as the easy-peel labels and the high-adhesion double-sided tapes.
High-Performance Feature Trends
Improved Physical Properties:
Higher Tensile Strength and Toughness: The addition of new materials and the optimization of the production process enable PET release printed films to have higher tensile strength and toughness, which can resist greater tension and impact during use and are not easy to break or tear.
Better Heat Resistance: In some high-temperature application environments, such as the packaging of some food that needs high-temperature sterilization and the processing of electronic components at high temperatures, PET release films with better heat resistance are required. The development of new heat-resistant polymers and additives has made it possible to improve the heat resistance of PET films.
Enhanced Chemical Resistance:
Acid and Alkali Resistance: In chemical, pharmaceutical and other industries, PET release printed films need to have good acid and alkali resistance to ensure that the printed information and the performance of the film are not affected in an acidic or alkaline environment.
Solvent Resistance: When in contact with organic solvents, such as in the process of printing and coating, PET release films should maintain their stability and not be dissolved or deformed by solvents. The development of new coating materials and surface treatment technologies helps to improve the solvent resistance of PET films.
Advanced Printing Performance:
Higher Print Resolution and Clarity: The continuous progress of printing technology enables PET release printed films to achieve higher print resolution and clarity. The printed text, patterns and images are more vivid and detailed, which is beneficial to improving the grade of products and the effect of brand promotion.
Faster Drying Speed and Better Ink Adhesion: New inks and printing processes have been developed to shorten the drying time of inks on PET films and improve ink adhesion, thus improving production efficiency and product quality, and making the printed content more durable and not easy to fade or fall off.
