FAQs – Bag Closing Machine

What purpose does a bag closing machine serve?
Bag closing machines are used to seal the tops of various types of bags for shipping and safely storing your products such as grains, food products, fertilizers and chemicals, cement, and animal food.
Industrial bag closer machines are widely used in agriculture, food processing, chemical manufacturing, construction, logistics, pharmaceuticals, and packaging industries.
An Armstrong bag closer will work with almost any type of bag closure, including woven polypropylene, high density polyethylene (HDPE), paper, cotton, and laminated and multi-layer bags.
The difference between sewing machines and heat seals is primarily due to the materials being used to close each type of bag. Sewing machines usually sew with a heavier thread to join heavier weight bags that may be reused multiple times; heat seals use heat to create a fully sealed and airtight bag closure. As a result, heat sealed bags are typically more suitable for food and chemical applications.
