JEFF Envelope Manufacturer was the predecessor of JEFF PACKAGING LIMITED prior to 2010. The company rebranded to its current name to better reflect its core business focus on diversified packaging product lines developed in recent years.

    Founded by Mr. Scott Ku in 1996, JEFF originally established its manufacturing base in Guangzhou. Built on efficient teamwork and agile operations, the company has maintained steady and rapid development. In June 2006, the factory relocated to Yangjiang, Guangdong, and formally established its subsidiary, JEFF ENVELOPE MANUFACTURER (YANGJIANG) LTD., with a registered capital of USD 1.3 million. Covering a plant area of 150,000 square feet, our facility achieves an annual output value of USD 10 million.    

    JEFF holds multiple technical patents and possesses advanced production software, hardware and processing technologies. Our exclusive low-temperature hot-melt coating technology for PE films, featuring sophisticated formulation and ultra-low-temperature strong adhesion performance, has obtained European patent certification. Equipped with over 30 sets of computer-controlled automated production equipment, our annual production capacity reaches 1.8 billion units. We are widely recognized as a professional supplier of adhesive packaging and postal packaging products, including security tamper-evident bags compliant with EU Cash EDI standards and US FedCash requirements, security tapes, packing list envelopes, courier bags, adhesive dust mitts, and related packaging accessories.

    Through years of technical accumulation and product iteration, we have formed two core product categories: plastic series and paper series. Our plastic product lineup covers EU Cash EDI and US FedCash certified security cash transport bags, general security bags, packing list envelopes, poly mailers, tamper-evident seals and more. Our paper series includes paper security bags, paper packing list envelopes, vinyl record paper sleeves, eco-friendly paper bags and other customized paper packaging solutions.

Furthermore, JEFF is officially listed as a qualified STEB manufacturer and distributor by ICAO.
