Description

Technical Field

[0001] This utility model belongs to the field of label hot stamping technology, specifically a label hot stamping mechanism. Background Technology

[0002] Hot stamping is the application of hot stamping technology in label production, creating a decorative effect with metallic luster and vibrant colors.

[0003] Label hot stamping utilizes the principle of heat transfer. By heating and applying pressure, the filter layer on the hot stamping foil is peeled off from the base film, and the aluminum layer is bonded to the substrate using a heat-sensitive adhesive. By precisely controlling the temperature and time, the label hot stamping process is completed.

[0004] During the manufacturing, transportation, or storage of label materials, static electricity can be generated due to friction and other reasons. Static electricity easily attracts dust particles in the air, causing them to adhere to the label surface. During the hot stamping process, this can result in problems such as blurred edges and uneven colors in the hot stamping pattern.

[0005] Therefore, this utility model provides a label hot stamping mechanism. Utility Model Content
