Claim:
A nonwoven web for use in producing beverage infusion pouches and bags, said web consisting of: a plurality of mono-component mono-constituent Polylactic Acid (PLA) fibers forming said web by dry thermo-bonding that is free from plasticizers and use of other special surface treatments, wherein said web provides for biodegradability after usage and recyclability of waste materials during each step of a manufacturing process of said web; the mono-component mono-constituent Polylactic Acid (PLA) fibers having an amorphous portion and a crystalline portion; the amorphous portion for facilitating ease of melt and flow around the crystalline portion so that the fibers self bond through at least one of web heating and pressure applications; wherein said mono-component mono-constituent Polylactic Acid (PLA) fibers form pore sizes of the web that are maintained if infused with hot liquids to enhance flow.
