贝卡尔特特殊镀膜公司(Bekaert Specialty Film Co., Ltd.,以下简称BSF)是国际公认的薄膜金属化、涂布和复合行业领导者，是全球第一家采用美国航空航天技术生产窗膜的窗膜生产商。

BSF所生产的窗贴膜具有隔热、节能、防爆、安全、美观等卓越品质。1994、1995年，公司连续两次获得国际金属化涂布与复合生产商协会（AIMCAL）年度技术大奖，代表着行业最高技术水平。BSF已经成为全球最大的高性能窗膜生产商，拥有多项世界领先窗膜利技术与专利产品。旗下的K牌玻璃膜早已进入中国，广泛应用于汽车和建筑市场。

Bekaert Specialty Films Corporation (Bekaert Specialty Film Co., Ltd., Hereinafter referred to as BSF) is an internationally recognized film metallization, coating and laminating industry leader, is the world's first use of U.S. aerospace technology to produce window film window film manufacturers.

BSF window films manufactured with insulation, energy, explosion, safety, aesthetics, etc. excellent quality. 1994 and 1995, the company won two consecutive international metal coating and composite Manufacturers Association (AIMCAL) Technology of the Year Award, representing the industry's highest level of technology. BSF has become the world's largest manufacturer of high performance window film, window film has a number of world-leading proprietary technology and patented products. the K quantum film has already entered the Chinese brand of metal film is widely used in automotive and construction markets.

BSF运用先进的磁控溅射生产技术，把不锈钢、钛、 镍、金、银、铜等贵金属制成透明隔热合金层，使窗膜在隔热功能大幅度提高的情况下同时具有很高的视觉清晰度，解决了染色－热蒸发工艺生产的窗膜透光率低、高反光、隔热功能差、视觉模糊、易褪色、耐腐蚀性差等诸多缺陷。目前，BSF已经成为全球最大的高性能窗膜生产商和销售商，拥有多项世界领先窗膜专利技术与专利产品， 也是全球7家被国际窗膜协会（IWFA）认可的生产商之一、全球仅有的3家具备磁控溅射窗膜生产能力的厂商之一，并被IWFA推荐使用。

BSF magnetron sputtering using advanced production technology, the stainless steel, titanium, nickel, gold, silver, copper and other precious metal alloy made of transparent insulation layer, the window film insulation function in the case of substantial increase in both high visual clarity, to solve the stain - the production of thermal evaporation process window film transmittance is low, high reflective, insulation is poor, blurred vision, fade, many defects and poor corrosion resistance. Currently, BSF has become the world's largest high performance window film manufacturers and distributors, the world's leading window film has a number of patented technologies and proprietary products, is the world's seven by the International Window Film Association (IWFA) approved manufacturers, the world's only three windows with magnetron sputtering film production capacity of manufacturers, and is IWFA recommended.
