Bag flattener conveyors are used to flatten filled bags for uniform stacking. Filled bags are “squeezed”, shaping the bags to a uniform “brick-like” shape for better palletizing. Uniformly flattened bags ensure less product spillage and product damage due to uneven pallet loads.
Depending on the product, bag flattening conveyors can be dual belts or roller/belts. The roller/belt bag flatteners are used with free-flowing products like corn or granules. Dual belt bag flatteners are used with non-free-flowing products like flour or soil.
Bag flatteners are usually located after a bag kicker/turner and before a transfer conveyor. Inpak Systems offers bag flatteners from Chantland, ESP, JEM, and Rapat.

Bag Flattening Conveyors FAQs
Top-Belt flatteners have a powered overhead conveyor belt running synchronously with the bottom conveyor providing gentle, continuous compression, making it ideal for multi-wall paper and plastic film bags.
Roller Conditioning Plates flatteners use a series of weighted, non-powered steel rollers mounted over a standard belt conveyor. This applies targeted impact compression, which is highly effective for heavy, coarse aggregates like sand, concrete mixes, and minerals. Contact us for help choosing a bag flattener.
Bag flatteners can accommodate multi-wall paper bags, woven polypropylene (PP), laminated poly-woven, and thick polyethylene (PE) plastic film bags.
Bag flatteners can process pillow-style bags, gusseted bags, and bags using various closures, such as sewn seams, heat seals, or ultrasonic pinch valves.
Standard flatteners can handle 20 lbs. to 110 lbs. (10 kg to 50 kg) bags.
Yes, our bag flatteners feature manual or automated actuators to modify the gap clearance between the top compression assembly and the bottom carrying belt.
Yes, Because the flattener clamps the bag firmly from both the top and bottom, It can transport flattened bags up/down an incline angle of up to 30 degrees.
Bag flatteners with variable-speed electronic drives (VFDs) can be synchronized to match the exact output of your bagging machine. Speeds typically range from 30 to 90 FPM (e.g. 15 to 30+ bags per minute).
Yes, upgrades are available. Contact our technical engineers with your requirements and they can recommend a model that meets your needs.
