Do Lug Cap Liners Support PVC-Free and Eco-Friendly Materials?

Environmental Protection and Food Safety Trends

With the rise of global environmental awareness, more and more food and beverage brands are paying attention to the use of PVC-free and eco-friendly materials in food and pharmaceutical packaging. This is not only about environmental friendliness but also concerns the safety and regulatory compliance of food contact materials.

Especially in the European and American markets, many companies are actively seeking "chlorine-free" or "environmentally friendly" cap liners to reduce their product’s environmental impact and meet the requirements of the green supply chain.

Against this background, industry players often ask: Do current lug cap liners fully support PVC-free and eco-friendly materials?

Current Status and Limitations

Kamellia continues to pursue quality and innovation in product development. However, at present, lug cap liners have not yet fully supported PVC-free or eco-friendly materials. This is not due to technical shortcomings but rather due to the current industry landscape and material characteristics.

PVC liners have long been widely used in metal caps because they provide:

• Excellent sealing performance: Effectively prevents leakage and ensures product freshness.
• High heat resistance: Capable of withstanding retort sterilization and pasteurization processes.
• Mature supply chain: Currently the most widely used solution in terms of cost and stability.

Although alternative materials are available on the market, large-scale applications still face challenges such as stability, heat resistance, and regulatory certification. Therefore, Kamellia’s current lug cap products still use traditional materials to ensure quality and food safety that meet industry standards.
