When selecting materials, flexibility and thinness should be prioritized to ensure the sticker adheres seamlessly to the curved surface without adding extra weight. Ultra-thin PET film (50–80μm) or soft PVC materials work well, as they can bend naturally with the curve, avoiding bubbles and wrinkles. A matte or semi-gloss coating can enhance tactile quality while

(1) Functional requirements: Ensuring basic performanceFunctionality is the “bottom-line” requirement for seal stickers. It should be determined according to product transport, storage, and usage conditions. For e-commerce packages shipped by courier, friction resistance and adhesive strength are critical to avoid tearing or detachment during sorting and handling. For refrigerated food (e.g., fresh produce, dairy), stickers

The consistency of raw materials is the fundamental prerequisite for achieving uniform color blending, requiring strict control from both ink and substrate perspectives. As the core carrier of color presentation, ink batch stability directly impacts blending results. It is essential to purchase inks from the same brand and model to avoid discrepancies caused by pigment

Its main advantages lie in the controllable surface finish and high color performance. The base paper, often made from wood pulp or cotton pulp, is dense with moderate stiffness. Through adjustments in coating composition and application, several subtypes are derived. For example, high-gloss coated paper features an extremely smooth surface with gloss exceeding 80%, resulting

For premium appeal, the metallic sheen of foil labels can be enhanced through gold stamping or matte finishes, creating a high-end look. Examples include gold foil labels on luxury chocolate gift boxes to highlight exclusivity; aluminum foil labels on aged Pu’er tea cakes for moisture protection and laser-engraved branding; and foil neck labels on high-end

The “brightness” of fluorescent stickers essentially comes from the process where fluorescent pigments absorb external light (such as natural sunlight or fluorescent lighting) and convert it into visible light—this is called photoluminescence. Different types of fluorescent pigments vary greatly in luminous efficiency and brightness decay rate, making pigment selection the decisive factor for brightness. Currently,
