MD20 Tea bag packaging

Machine overview

Simple and versatile.

A mid to low-speed packaging machine for non-heat-sealable, double-chamber, knotted bags for tea and herbs, the MD20 processes either naked bags or bags in heat-sealed outer envelopes.
Equipped with an optional automatic cartoning attachment for pre-glued cartons, the MD20 can also be fitted with a hand-removal unit for counted or uncounted teabags, according to customer needs.
Production is constantly monitored by dedicated supervision software and a video camera which checks knotting and teabag conformity.
