Are Your Products Certified for Food Contact Safety and Chemical Leaching?

When it comes to drinkware and food storage products, safety is non-negotiable. At Healthkin + Jakon, a division of Zhejiang Jiakang Stainless Steel Product Co., Ltd., we understand that the materials that touch your food and beverages must be free from harmful chemicals and designed to prevent leaching. In this article, we walk you through our quality assurance process, the third-party certifications we pursue, and how we ensure every mug, tumbler, quencher, vacuum flask, hydration bottle, and large jug meets strict food contact safety standards.

Our Commitment to Food Contact Safety

All products manufactured under the Healthkin + Jakon brand—whether stainless steel, plastic, or silicone components—are produced in our facility located in Wuyi, Zhejiang. We prioritize the use of food-grade materials: 18/8 stainless steel, BPA-free plastics, and FDA-compliant silicone seals. Our raw materials are selected after rigorous supplier audits, and every batch is tested to confirm that no toxic substances like lead, cadmium, or phthalates are present.

Chemical Leaching Prevention

Chemical leaching can occur when low-quality materials interact with acidic or hot liquids. To prevent this, our products undergo a multi-step surface treatment process. For stainless steel products, we employ electro-polishing and passivation to create a non-reactive surface, ensuring that no metallic ions migrate into your drinks. For our plastic components, we use only food-contact-grade polymers that are stable across a wide temperature range. We also conduct extraction tests in independent laboratories to simulate long-term usage and verify that no chemical migration occurs.

Third-Party Certification and Testing

We believe in transparency. That is why we actively work with accredited third-party testing organizations to validate the safety and quality of our products. Our testing protocols cover:

• FDA 21 CFR compliance for materials intended for repeated food contact.
• EU 10/2011 migration testing for plastic materials in contact with food.
• LFGB (German) testing, known for its comprehensive sensory and migration requirements.
• Proposition 65 screening to ensure no reportable levels of listed chemicals.

Each product line—including our mugs, tumblers, quenchers, vacuum flasks, hydration bottles, and large jugs—can be accompanied by a certificate of conformity upon request. Our quality control team continuously monitors production processes to ensure that every unit leaving our factory meets the highest safety benchmarks.

In-House Quality Control Process

Beyond third-party certifications, we maintain a robust in-house quality management system. Every batch is inspected at multiple stages: incoming material inspection, in-process dimension and surface checks, leak testing, and final visual and functional verification. We also perform accelerated aging tests and dishwasher cycle tests to ensure that product integrity and safety are maintained throughout the product’s lifetime.

Customized Solutions for Your Safety Requirements

We know that different markets and customers may have specific safety requirements. That is why we offer customizable testing and certification options. Whether you need special migration tests for food simulants, specific component declarations, or documentation for regulatory submissions, our team is ready to assist.
