The quality standards for PET thermosensitive matte silver paper usually cover multiple aspects to ensure its performance in practical applications. Here are some key quality standards:
1、 Appearance quality
Surface flatness: The surface of PET thermosensitive matte silver paper should be flat, smooth, and free of bubbles, damage, wrinkles, and other phenomena.
Coating uniformity: The matte silver special coating should be evenly applied to the surface of the paper to ensure printing quality and aesthetics.
Color consistency: The color of the paper should be consistent, without obvious color differences or spots.
2、 Printing performance
Printing clarity: PET thermal matte silver paper should have good printing clarity, able to present clear and sharp images and text.
Printing speed: The paper should be able to support faster printing speeds to meet the requirements of efficient printing.
Printing adaptability: Paper should be suitable for multiple printing methods, such as thermal printing, heat transfer printing, etc., and be able to maintain good printing effects under various printing conditions.
3、 Durability
Waterproof: PET thermal matte silver paper should have good waterproof performance and be able to maintain the clarity and stability of labels in humid environments.
Oil resistance: Paper should be able to resist the erosion of oil and ensure the durability of labels in oily environments.
Abrasion resistance: Paper should have strong abrasion resistance and be able to maintain the integrity and clarity of labels during use.
High temperature resistance: In high temperature environments, paper should be able to maintain stable performance without deformation, fading, or other phenomena.
4、 Environmental performance
Recyclability: PET thermal matte silver paper should be made of recyclable materials that meet environmental requirements.
Harmlessness: Paper should not release harmful substances such as phenolic compounds, heavy metals, etc. during production and use.
