Tunsing Releases New DS318 Hot Melt Adhesive Film rolls Empowering the 3C Packaging Industry with Precision Temperature

Shenzhen Tunsing Plastic Products Co., Ltd. (hereinafter referred to as "Tunsing") has officially released the latest version (V1.4) of its DS318 Hot Melt Adhesive Film. Specifically designed for 3C product packaging, battery packaging, and mobile power packaging, this hot melt adhesive defines new industry standards through its superior low-temperature processing and precise physical properties.

DS318 is an eco-friendly thermoplastic hot melt adhesive film based on ethylene synthesis modification technology. Featuring an amber translucent appearance, this product is supported by release paper and can be repeatedly heated and plasticized. It demonstrates exceptional adhesion to textiles, metals, plastics, and wood.

Key Technical Highlights:

• Physical Density: Strictly controlled at $1.0pm0.02g/cm^{3}$.

• Melting Range: Features an ideal melting interval of 65-90°C, significantly reducing processing energy consumption.

• Activation Threshold: The activation temperature starts as low as 75°C, ensuring the protection of heat-sensitive substrates.

• Flexible Specifications: Thickness options range from 0.05mm to 0.10mm, with support for custom widths from 5mm up to 1480mm.

The Tunsing R&D team has conducted exhaustive characterization of DS318 using advanced laboratory equipment. In the latest technical data sheet, Tunsing disclosed the product’s Differential Scanning Calorimetry (DSC) analysis curve, showing a clear endothermic peak near 80.0°C, which ensures thermal stability during the melting process.

Furthermore, rotational rheometer tests confirm that DS318 reaches its transition from a viscoelastic solid to a viscoelastic fluid at approximately 84.2°C. This precise feedback on physical characteristics allows manufacturers to establish ideal bonding conditions when setting secondary lamination temperatures between 110°C and 160°C.

To meet the dual demands of efficiency and aesthetics in the 3C packaging sector, DS318 offers a highly competitive processing window. Under a pressure of 0.3-0.6 MPa, efficient bonding can be achieved in just 5 to 25 seconds. This characteristic not only shortens production cycle times but also ensures ease of operation during die-cutting and automated assembly thanks to the glassine release paper protection.

Shenzhen Tunsing Plastic Products Co., Ltd. has been deeply involved in the hot melt adhesive field for many years, consistently relying on laboratory data to provide professional and reliable bonding solutions for global customers. The release of DS318 marks another milestone in Tunsing’s pursuit of product refinement and technical excellence.
