The surface of laminated business cards is dense and has low polarity, making it easy to “fake stick” when directly glued. The key is to choose the right adhesive type, treat the surface well, control the temperature and pressure, in order to stick firmly.
Sunlifehot melt adhesiveThere are models specifically designed for laminated surfaces, and Guangzhou Sunlife Trading can provide small sample adhesion testing. Before mass production, it is necessary to conduct a tensile test to confirm that there is no delamination before proceeding to the production line.
Q: Why did it open again after being pressed down?If the opening time is missed or the pressure is insufficient, adjust the pressing timing.
Q: Can ordinary glue be used for gluing?The adhesion of the film is poor, and the special adhesive is more secure.
Hot melt adhesive granulesIs it environmentally friendly or toxic? Legitimate hot melt adhesive particles themselves are thermoplastic polymers that are solid, non-volatile, and insoluble in water at room temperature, making them relatively safe adhesive materials. Whether it is “toxic” mainly depends on the formula and high-temperature usage method. Looking at safety from three aspects raw […]
The procurement risks of industrial chemical raw materials such as chromium powder often occur after placing an order: unclear packaging labeling, incomplete delivery upon arrival, and missing storage and requisition records all increase the difficulty of subsequent traceability. Starting from the procurement handover chain, this article explains how to establish basic control points. Core KeywordsChromium […]
Direct answer: It’s not the same thing Hot melt adhesive granulesThe testing report often mentions “softening point”, but rarely includes “melting point”. The reason is simple: this type of adhesive is mostly an amorphous polymer blend system, without a clear melting point like crystals, only a gradually softening temperature range. The softening point is an […]
Let’s first clarify what REACH actually covers REACH is the chemical regulation of the European Union, which regulates “substances” rather than “whether a product is good or not”.Hot melt adhesive granulesAs a mixture exported to the EU, there are two core obligations: first, each substance in the formula must be registered or exempted from compliance […]
