Abstract
A multi-phase, non-heat seal tea bag web material is provided with a pattern on either the top or bottom phases. The top phase is formed from fibers, such as hardwood, that provide a tighter or more dense fibrous phase than the vegetable fibers used in the base phase. Patterning can be provided during web formation by using a knuckled wire or by applying a fluid jet against the top of the web material. The sifting characteristics of the multi-phase web material are comparable to or better than that exhibited by single phase material.
