Evaluating the quality of PET matte silver thermal label paper can be considered from multiple dimensions, including material characteristics, printing effect, durability and production details. Here are some specific assessment methods:
1. Material characteristics
PET material: Confirm whether the label paper is PET material, PET material has good hard brittleness, temperature resistance (usually in the range of -60 ° C ~ 150 ° C), light resistance (not easy to fade), transparency and corrosion resistance (can resist a variety of chemicals). Matte silver PET has a special uniform coating on the surface, giving it a unique matte silver effect.
Thickness: The thickness of common PET matte silver thermal label paper is 25U, 50U, 75U, 100U, 150U, etc. The greater the thickness, the more difficult it is to foam when printing. The specific thickness selection should be determined according to the actual demand.
2. Print effect
Clarity: the printed label text and pattern should be clear and recognizable, without blurring, gaying and other phenomena.
Stability: During the printing process, the label paper should be stable to avoid paper jam and deviation.
3. Durability
Waterproof: Test whether the writing is still clear after the label is soaked in water for a long time.
Corrosion resistance: Soak the label paper in a chemical solvent such as gasoline and observe whether the ink will be corroded or blurred.
Tear resistance: Tear the label paper left and right to test whether it is easy to tear or break. High quality PET matte silver thermal label paper should have strong tear resistance.
Scratch resistance: Use a hard object to slide and scratch on the label surface and observe whether the writing will fall off. Matte silver PET label paper usually has good scratch resistance.
High temperature resistance: Test the performance change of the label paper in a high temperature environment. High-quality label paper should still be clear and the paper should not be deformed at high temperature.
4. Production details
Packaging and hygiene: Choose the label paper with intact packaging and inner paper core. The surface of the paper should be clean and hygienic, without dust and imprint.
Die-cutting and spacing: Check whether the strip behind the paper die-cutting is divided, whether the side of the paper roll is clean, and whether the spacing and margin between the paper and the paper are consistent.
Adhesiveness: Attach the label to a clean, smooth surface, test its adhesion and whether it is easy to tear off without leaving residue.
5. User evaluation and feedback
Refer to the evaluation and feedback of other users to understand the performance of the brand or model of PET dumb silver thermal label paper in actual use. This information can be obtained through e-commerce platforms, industry forums, etc.
In summary, evaluating the quality of PET dumb silver thermal label paper needs to be comprehensively considered from many aspects. You are advised to select an appropriate product based on actual requirements and application scenarios.
