The manufacturing process of epoxy resin labels is mainly divided into two categories: industrial mass production and handmade customization. The core process involves forming a highly transparent, wear-resistant, and scratch-resistant "crystal epoxy" or "dome effect" layer on the label surface using epoxy resin (usually an A/B two-component system). The following is a summary of key process steps based on authoritative publicly available information:
The manufacturing process of epoxy resin labels mainly includes key steps such as material preparation, printing, lamination, epoxy resin application, curing, and die-cutting. The entire process needs to be carried out in a strictly controlled temperature and humidity environment to ensure stable label quality.
Material Preparation and Printing: High-quality face stock is selected, requiring a gloss deviation controlled within ±5% and a density uniformity of over 98%. The designed pattern is first printed onto the self-adhesive face stock, commonly using flexographic or offset printing.
Lamination Process: After printing, a transparent film is applied to the surface to enhance the label's abrasion resistance, water resistance, and UV resistance, extending its lifespan.
Epoxy Resin and Curing: Imported epoxy resin is dripped onto the label surface to form a glossy, transparent crystal layer. This process must be completed in a workshop environment with a temperature of 22±2℃ and a humidity of 55±5%RH to ensure consistent resin flow and curing effect.
Die-Cutting: The entire sheet of material is cut into the desired shape using a die, enabling complex patterns and personalized designs.
