What are stand-up pouches (Doypack) and why are they popular for tea?

Stand-up pouches feature a bottom gusset that allows the bag to stand upright on shelves, improving product visibility and consumer convenience. 

They are among the most popular packaging types for loose-leaf tea and specialty blends. These pouches often include resealable zippers, tear notches, and support high-quality printing for strong branding. 

They are typically made from laminated materials like PET/AL/PE or BOPP/AL/CPP, providing excellent barrier properties against moisture and oxygen.
