I. Compatible Substrate Types
Silver hot foil offers broad compatibility with commonly used industrial substrates. Key compatible options include: paper/carton without pre-treatment , enabling direct and firm hot stamping; polar plastics like PET, PVC, and ABS, where the adhesive layer quickly wets the surface and cures via thermal melting to meet peel strength standards; non-polar plastics such as PE and PP treated with corona , which resolves adhesion issues; flexible special versions suitable for leather and fabrics, resisting bending without peeling; and high-temperature special versions compatible with metal substrates like aluminum and stainless steel, forming reliable mechanical bonds to cover substrate needs across packaging, home appliances, automotive, and other industries.
II. Incompatible Substrate Types
Due to inherent property limitations, some substrates have low or no compatibility with this material. These include: untreated non-polar plastics like PE and PP, whose excessively low surface energy prevents adhesive adhesion, leading to easy overall peeling after hot stamping; high-roughness materials such as wood and crude rubber, where the foil layer cannot fully adhere, causing pinholes and bubbles; materials coated with low surface tension layers like silicone and fluorocarbon, to which the adhesive barely adheres with no bonding effect; undried porous substrates, which release water vapor at high temperatures, resulting in foil layer haze; and low-temperature sensitive plastics with a thermal deformation temperature ＜80℃ , where hot stamping temperatures cause substrate deformation and melting.
III. Compatible Processes and Equipment
In industrial production, this material seamlessly integrates with various mainstream processes and equipment. It is compatible with different hot stamping machines, fully matching the parameter range of 80-180℃ temperature and 0.3-0.6MPa pressure without requiring equipment modifications. It is compatible with subsequent processes such as lamination, UV curing, normal die-cutting, and thermal sealing below 120℃, with quality issues avoidable by selecting the corresponding special version. It adapts to high-speed production rhythms of 10-50m/min, supporting small-batch customization to large-scale production of millions of units, with high stability for products in the same batch to meet diverse production capacity needs.
IV. Incompatible Processes and Scenarios
This material has low compatibility with certain special processes, environments, and requirements. It cannot withstand harsh processes such as thermal sealing above 120℃ or UV curing exceeding 30 seconds, which easily cause foil layer carbonization and discoloration. It is unsuitable for outdoor environments with long-term exposure to high humidity and strong UV radiation, as this accelerates oxidation and gloss loss. In scenarios involving contact with strong solvents like acetone and toluene, the foil layer dissolves and peels off. It cannot meet high-frequency contact requirements for wear resistance exceeding 500 cyclesdue to insufficient wear resistance of standard versions. Additionally, products without environmental certification are incompatible with scenarios requiring strict compliance, such as food contact applications and EU exports.
