Fully Automatic Roll Fed Flat Handle Paper Bag Machine Series

The fully automatic roll fed flat handle paper bag machine uses roll paper and roll paper handles as the raw material, and can carry out flat handle manufacturing, handle patching, tube forming, tube cutting, bottom forming, and compaction output in one continuous operation. It is especially suitable for large scale production of bags for food packaging and clothing. It also features a fully automatic production.  

A flat handle (internal) paper bag has the same weight capacity as that of a twisted handle bag, and is relatively inexpensive to manufacture. The flat handle inside the bag significantly reduces the packing case size and the cost. Machine operation is simple and efficient, lending to its popularity on the market today.
