In the growing market of sustainable packaging, Hiroyuki Industries (M) Sdn Bhd has established itself as a key player in the production of food-grade recycled PET (rPET). Founded in 2001 and based in Johor Bahru, Malaysia, the company is a subsidiary of Japan’s Hiroyuki Co., Ltd.. Hiroyuki is specialized in rPET resin and high-quality packaging solutions tailored to the food and beverage industry. Its product portfolio includes food-grade rPET resin for bottle-to-bottle recycling, as well as strapping bands, stretch films, and tying twines for general packaging applications. To ensure that only the highest quality material leaves the facility, Hiroyuki relies on the advanced capabilities of SIKORA’s PURITY CONCEPT V system for optical inspection and analysis.

Integrated into their quality control laboratory, the system inspects rPET samples before shipment and automatically detects visual defects such as black specks and discolorations on the pellets, and other contaminants as small as 50 micrometers. By replacing manual inspection processes, the PURITY CONCEPT V significantly increases accuracy and efficiency in quality control.
“With the PURITY CONCEPT V, we have significantly improved our ability to detect visual contaminants of the pellets. This not only enhances product quality but also boosts confidence in our material among our customers,” says Chan Shuang, QA Assistant Manager at Hiroyuki.
The use of the PURITY CONCEPT V has led to measurable improvements in product consistency. Defects are detected earlier, allowing for immediate corrective action and reducing the number of non-conforming batches. Each inspection is recorded and archived, creating a reliable data trail that supports traceability, customer assurance, and regulatory audits. This data includes the number and size of defects, providing the team with valuable insights for ongoing process optimization.
At Hiroyuki, optical inspection systems like the PURITY CONCEPT V are considered a key element in ensuring compliance with strict international standards such as those set by the EU, FDA, and EFSA. The system supports the company’s mission to deliver safe, high-performance recycled materials to its customers while continually refining its internal processes. Looking ahead, Hiroyuki aims to evolve into a comprehensive hub for rPET resin, preforms, and bottle production within its region. With a clear focus on innovation and quality, the company is well-positioned to lead the way in sustainable packaging solutions for years to come. A partner on this way is SIKORA and its inspection technology.
