From Food to 3C Products: Practical Application Cases of BOPP Heat-S Sealable Film Across Industries

In food packaging, it serves as the material of choice for instant noodles, frozen foods, and snack packaging bags. For example, a renowned instant noodle brand uses BOPP heat-sealable film for bowl noodle lids, achieving precise sealing within 3 seconds via high-speed heat-sealing equipment. This not only effectively prevents oil-fried noodles from absorbing moisture and deteriorating but also showcases ingredients vividly through its high light transmittance (up to 92%). In the frozen food sector, multiple chain dumpling brands employ composite packaging bags with BOPP heat-sealable layers, ensuring that heat-sealed edges remain tightly sealed at -18°C low temperatures to avoid dumpling sticking and damage.

In daily necessities and industrial applications, it is widely used in detergent packaging bags, cosmetic soft packaging, and dust-proof/moisture-proof packaging for textiles and electronic products. An international daily chemical brand uses 3-layer co-extruded BOPP heat-sealable film for laundry detergent packaging, expanding the heat-sealing temperature range to 120–180°C to adapt to different production line equipment, with a single production line capable of producing up to 500,000 bags daily. In textile packaging, fast-fashion brand ZARA widely uses BOPP films with heat-sealable edges for garment dust bags, allowing consumers to re-seal the bags via pre-installed heat-seal strips after opening, enhancing reusability. In the 3C products sector, Huawei uses anti-static BOPP heat-sealable films for inner packaging of mobile phone accessories, enabling rapid heat-sealing of data cables and chargers while preventing potential electrostatic damage to precision components.
