One of the primary characteristics of high temperature oil seals is their ability to maintain flexibility and resilience at elevated temperatures. Traditional rubber seals may become brittle and lose their sealing capabilities when exposed to heat. In contrast, high temperature oil seals retain their mechanical properties, ensuring that they continue to perform their sealing function effectively even in harsh conditions. Typically, these seals can withstand temperatures ranging from 150°C to over 300°C, depending on the specific material used.

2. Freshness Preservation One of the primary goals of packaging is to protect the contents from external elements, and hot tea packaging pouches excel in this area. They are typically made from multi-layer materials that secure the freshness of the tea by preventing exposure to air, moisture, and light. This preservation is essential for maintaining the tea's flavor and aroma, ensuring that consumers enjoy the full experience of their beverage.
