What Is an Automatic Paper Bag Making Machine?
An automatic paper bag making machine is a piece of industrial equipment that converts kraft paper rolls into finished paper bags in one fully automatic workflow. It integrates feeding, forming, gluing, cutting and counting to produce consistent, high-quality bags for food, retail and shopping packaging. This guide explains its definition, two main types, core functions and practical values for B2B purchasers, production managers and factory owners.
1. What Is an Automatic Paper Bag Making Machine?
An automatic paper bag making machine is a PLC-controlled industrial device that processes roll paper into standard paper bags without manual intervention. It supports different paper weights and bag shapes, with high speed, stable precision and low labor requirements. It is the core production equipment for modern paper bag factories and packaging plants.
Our automatic models include high-speed v-bottom and flat-bottom versions to match food packaging and shopping bag demands.
2. Main Types of Automatic Paper Bag Making Machines
Automatic paper bag making machines are divided into two mainstream types based on bag bottom structure. Each serves different packaging scenarios.
2.1 V Bottom Paper Bag Making Machine (ZM-JD400V)
The ZM-JD400V is a high-speed machine dedicated to v-bottom (pointed-bottom) paper bags. It runs at 60–500pcs/min, processes 40–80g/㎡ food-grade kraft paper, and complies with EU food packaging standards. It is widely used for fast food, snacks, bakery and takeaway packaging bags.
