Anhui Go-wins (WATOW HTM) Metal Technology Co., Ltd. drives the digital printing revolution through its core DTF heat transfer film technology, empowered by cutting-edge coating/slitting systems and precision quality control. As a technology-based enterprise, we deliver comprehensive DTF solutions including premium films, inks, and hot melt powders, advancing innovation across apparel decoration, new energy labeling, and home appliance sectors. Our expertise in advanced coating technology further extends to specialty materials like foil pressure-sensitive tapes and heat-sealable aluminum foils, creating a dual-engine strategy of "DTF leadership + diversified material innovation". As Printable Heat-Sealable Film Suppliers and Printable Heat-Sealable Film Factory in China, all products meet RoHS/REACH international certifications, with quality endorsed across 30+ global markets.
Aluminum-free heat-sealing films are widely used to meet the needs of transparent packaging, metal detection, or cost control.
Common Structures:
1. Transparent High-Barrier Film: Such as PET/ALOx or SiOx/CPP. Utilizing an alumina or silica coating to provide high barrier properties while maintaining transparency, allowing the contents to be clearly seen.
2. Multilayer Co-extruded Film: Such as PET/PE or OPP/CPP. Achieving certain moisture-proof, oxygen-barrier, and heat-sealing properties through a combination of multiple layers of plastics with different properties.
Features:
Transparent and Aesthetically Pleasing: Showcases the product itself, enhancing its appeal.
Microwaveable/Metal Detectable: Metal-free, making it more convenient and safer to use.
Environmentally Friendly and Recyclable: Some structures are made of a single material, facilitating recycling.
Barrier Properties are Slightly Inferior to Aluminum Foil: However, it is sufficient for products with short shelf lives or less stringent barrier requirements.
Typical Applications: Jelly cups, dessert cups, sauce cups, instant beverage bottle cap sealing, and food packaging requiring metal detection.
