LIWUNON Achieves ETL and GRS Certifications, Reinforcing Its Commitment to Safety and Sustainability

 LIWUNON, a technology-driven brand focused on advancing vacuum food preservation, today announced that its vacuum sealer has successfully obtained both ETL certification and GRS (Global Recycled Standard) certification, marking a significant milestone in the company’s journey toward building safer, more responsible products.

These certifications reflect LIWUNON’s ongoing commitment to engineering excellence, consumer safety, and environmental responsibility.

ETL Certified — Safety You Can Trust

The ETL mark, issued by Intertek, confirms that LIWUNON’s vacuum sealer complies with strict North American safety standards.

For consumers, this means confidence in everyday use.
For LIWUNON, it represents something deeper:

A product built not just to perform—but to perform safely, consistently, and reliably over time.

Every unit is designed and tested to meet rigorous electrical and operational safety requirements, ensuring peace of mind in every use.

GRS Certified — A Step Toward Sustainable Manufacturing

In addition to safety, LIWUNON is committed to reducing environmental impact.

The Global Recycled Standard (GRS) certification verifies that materials used in the product or its packaging meet strict requirements for recycled content, traceability, and responsible production practices.

This means:

  • Greater use of recycled materials
  • Transparent and traceable supply chains
  • Reduced environmental footprint

Because better products shouldn’t come at the expense of the planet.

Built on Real Engineering, Not Assumptions

At LIWUNON, certification is not the goal—it’s the baseline.

Our products are developed through extensive real-world validation:

  • 1,500+ hours of motor and pump durability testing
  • Testing across 46+ brands and 200+ machines
  • Analysis of 100,000+ customer reviews

We study what fails, so we can build what lasts.

More Than Compliance

“Achieving ETL and GRS certifications is an important step, but it’s only part of our journey,” said a LIWUNON spokesperson.
“We believe great products must be safe, reliable, and responsible—from how they perform to how they are made.”

  • Strong yet controlled vacuum performance
  • Reliable, airtight sealing
