Overview

Thong Guan Industries Berhad (TGIB) is a Malaysian manufacturer of plastic and flexible packaging products, headquartered in the northern state of Kedah. The business began in 1942 as a small family trading concern founded by Mr. Ang Thong Guan, who sold tea by bicycle in the town of Sungai Lalang, Kedah. His sons Dato' Ang Toon Cheng and Dato' Ang Toon Piah joined the business in 1945, and the family expanded beverage and consumer-goods distribution across the northern region of Peninsular Malaysia under the 888 brand. By the 1960s the company had diversified into plastics, producing raffia strings, drinking straws, plastic ropes, bags and sheets, and later paper products. A dedicated flexible packaging division, TG Flexible, was established in 1972. In 1997 Dato' Ang Poon Chuan became Managing Director and steered the group into stretch film production for industrial pallet packaging and unitization, a move that became central to its growth. Today Thong Guan describes itself as one of the largest manufacturers of plastic packaging products in Malaysia and among the fastest-growing companies in Asia Pacific. Its product range spans stretch film, stretch hood, shrink film and wrap, food cling wrap, industrial and consumer flexible packaging, additives, and food and beverage products. Core manufacturing is concentrated on a site of over 20 acres in Kedah, with additional operations in Sabah, China and Thailand, and overseas sales offices serving export markets. The company is listed on the Main Board of Bursa Malaysia (formerly the Kuala Lumpur Stock Exchange) and reports annual turnover of over USD 180 million, growing at an average of about 10% per year. It positions itself around innovation and sustainability, citing technologies such as nanotechnology cast lines for thin-gauge film and in-line MDO during extrusion. Governance is aligned with the Malaysian Code on Corporate Governance, supported by board charters, committees and policies covering risk, whistleblowing, anti-corruption and business ethics.

History

Thong Guan's history begins in 1942, when Mr. Ang Thong Guan started selling tea from a bicycle in Sungai Lalang, a small town in the northern Malaysian state of Kedah. The venture grew enough for the founder to acquire the company's first Chevrolet van. In 1945 his sons, Dato' Ang Toon Cheng and Dato' Ang Toon Piah, joined the family business, and together they extended the tea trade across the Northern Region of Peninsular Malaysia. Within three years the company had built a marketing network and a fleet of vans distributing beverages and consumer products to grocery and coffee shops, food outlets and general traders, operating under the 888 brand. By the 1960s the company diversified into the plastics industry, manufacturing products such as raffia strings and drinking straws and later expanding into plastic ropes, plastic bags and sheets, paper serviettes and cologne paper towels. This marked the beginning of its transformation into a major plastic packaging manufacturer. In 1972 the group established TG Flexible, a flexible packaging division, which went on to produce a wide range of flexible plastic packaging and services for industrial and consumer use. In 1997 Dato' Ang Poon Chuan was elected Managing Director of Thong Guan Industries. Under his leadership the company entered stretch film production for industrial pallet packaging and unitization through TG Stretch, a strategic move as demand for multi-layer stretch film grew. Over subsequent decades Thong Guan expanded its manufacturing footprint beyond its Kedah base, establishing operations in Sabah, China and Thailand, and building a network of overseas sales offices. Its core manufacturing operations in the Northern Region of Kedah cover over 20 acres. The company became one of the largest producers of cast pallet stretch film and garbage bags in the region, and adopted technologies including a nanotechnology cast line for super-thin gauge film and in-line MDO during extrusion for sturdier films. Thong Guan Industries Berhad is listed on the Main Board of Bursa Malaysia (the Kuala Lumpur Stock Exchange). It reports annual turnover of over USD 180 million and average annual growth of about 10%, describing itself as one of the largest plastic packaging manufacturers in Malaysia and one of the fastest-growing companies in Asia Pacific. The group maintains corporate governance practices aligned with the Malaysian Code on Corporate Governance, including a board charter, audit, nominating and remuneration committees, and policies on risk management, whistleblowing, anti-corruption, business ethics and related-party transactions.
