Paper Envelope Bag Forming Machine

The Automatic Paper Envelope Bag Forming Machine is designed for the continuous production of flat paper envelopes, V-bottom lifafas and lightweight paper packaging bags. It processes kraft paper, white paper, brown paper and suitable food-grade paper through automatic feeding, alignment, side gluing, tube forming, length measurement, cutting, folding and collection operations.

Its photoelectric correction system helps maintain accurate paper alignment, while the digital length counter enables consistent envelope sizing during production. Adjustable forming and cutting arrangements allow different envelope dimensions to be produced on the same machine. The heavy-duty mild-steel body provides stable operation, and the user-friendly electrical control panel allows convenient speed and production control. This machine is suitable for manufacturing pharmacy envelopes, bakery bags, grocery lifafas, seed envelopes, food-packing covers, stationery envelopes and general-purpose retail paper bags with uniform finishing and reduced paper wastage.
