Grandwin Showcases Surface Protection Materials at Mid-Autumn Employee Gathering
SHUNDE, Guangdong, Sept. 25, 2026 — Grandwin (Junying), a company specializing in Surface Protection Materials, hosted a Mid-Autumn Festival gathering at its Shunde headquarters, combining festive employee appreciation with a focused showcase of its latest product innovations. The event placed the company’s Masking Films, Door Edge Protection Film, and Polyester film at the center of the program, giving employees a deeper technical understanding of the products they help produce every day.
Product Portfolio Takes Center Stage
Grandwin’s core business revolves around Surface Protection Materials designed for demanding industrial applications. The company’s Masking Films series is manufactured using high-quality base paper and specially formulated adhesives, offering firm adhesion, easy tearing, and clean peel-off without residue. These Masking Films are widely deployed in building decoration painting, furniture manufacturing, and general industrial masking, where precise masking boundaries are critical to finished product quality. A recent addition to the line, Grandwin’s high-performance kraft adhesive paper, undergoes moisture-proof and tensile-resistant treatment to achieve superior toughness, withstanding high-temperature baking up to 130℃ for industrial coating processes. The product supports full-spec customization with widths from 20mm to 2100mm and grammages from 40g to 60g, and is produced using formaldehyde-free technology with VOC emissions well below EU REACH and US UL standards.
The Door Edge Protection Film line addresses a critical vulnerability in automotive and appliance manufacturing: the exposed edges of doors, panels, and structural components that are highly susceptible to chips, scratches, and impact damage during assembly, transport, and installation. Grandwin’s Door Edge Protection Film provides a durable, conformable barrier that adheres securely to edge profiles while remaining cleanly removable, preserving surface integrity from production through final delivery.
Grandwin’s Polyester film offering leverages PET substrate technology to deliver excellent abrasion resistance and enhanced scratch protection. The Polyester film is engineered for applications requiring high mechanical strength, thermal stability, and dimensional consistency, serving as a reliable protective layer in electronics manufacturing, insulation systems, and precision component handling. Together with PE-based options, Grandwin’s Polyester film gives clients the flexibility to select the ideal protective material based on specific environmental conditions and application needs.
Employee Engagement Focused on Product Knowledge
During the gathering, a dedicated product display area allowed employees to examine samples of Grandwin’s Surface Protection Materials, Masking Films, Door Edge Protection Film, and Polyester film up close. Technical staff explained performance characteristics, application scenarios, and correct handling procedures — building on the company’s ongoing practice of integrating product knowledge into employee training programs. Employees from production, quality control, and warehouse teams discussed how each product’s properties translate into real-world performance for customers in electronics, building materials, and furniture sectors.
A team member from the coating workshop noted that seeing the finished Masking Films and Polyester film samples helped connect daily production tasks to end-use applications. Another employee from the quality department said the Door Edge Protection Film demonstration clarified why adhesion consistency and clean removability matter so much in customer specifications.
Management Perspective
Management representatives visited production areas during the event, distributing holiday gifts and reinforcing the company’s commitment to both employee well-being and product excellence. A company spokesperson emphasized that Grandwin’s strength in Surface Protection Materials stems from continuous investment in substrate modification, adhesive R&D, and environmentally responsible manufacturing. The company’s Masking Films, Door Edge Protection Film, and Polyester film are exported to markets across Europe, the Americas, and Southeast Asia, with customer feedback driving ongoing product refinement.
Looking Ahead
Grandwin will continue to advance its Surface Protection Materials portfolio, optimizing Masking Films, Door Edge Protection Film, and Polyester film to meet evolving industry requirements. The company plans to expand production capacity and deepen technical collaboration with customers, ensuring that every product leaving its Shunde facility delivers reliable, measurable protection value.
