Customer Relationship Excellence
GC recognizes the opportunities in end-use market entry and acquiring new customer through differential technology and innovation by developing products with functional variety and high performance in response to better living of customers and end users.
GC has engaged with groups of customers and external organizations by modifying its organizational structure according to the type and nature of its business, in order to enhance customer and marketing management. In addition, GC has established the InnoPlus Solution Center for the plastic industry, to encourage collaboration between GC and its partners in developing and delivering value that increases customer satisfaction. As a result, customers develop attachment to and preference for the Company’s products and continue to purchase them.
The InnoPlus Solution Center is one of the channels to receive customers' opinions to develop innovations and products which will add value to businesses, communities and the society.
GC’s customers were introduced to the virtual tour of the InnoPlus Solution Center which facilitated the viewing and collaborative development of products. Furthermore, the company is committed to grow sustainably alongside its strategic partners who are brand owners and strives to expand product development collaborations with educational institutions and government agencies in a bid to create product development opportunities, increase trade options and expand customer base.
GC has been using customer recommendations and feedback from various channels, such as the VOC and CSC systems, as essential input for developing innovative products that respond to customer and market needs. With this approach, GC has been able to continuously develop environmentally-friendly, safe‑to‑consumer, low‑carbon products. In addition, GC closely monitors the performance of its product development to ensure the highest level of customer satisfaction.
Furthermore, GC has developed a labelling scheme and trade mark that verifies the quality of material or product that the Company produced. GC also set up activities to raise awareness on the importance of environmental friendly consumption behaviours. Moreover, GC also hold seminars and lectures for its customers and business partners in the petrochemical sector to develop their capacity in developing environmentally products and services that matches international standards, as well as support them to adjust their business to future demands.
