Back seal pillow pouches are typically formed from roll film into a tubular shape, then sealed longitudinally along the back and transversely at the top and bottom. This pouch format is widely used for snacks, candies, nuts, grains, seasoning powders, detergent powders and other loose products.

Runli can configure vertical form fill seal machines according to film material, pouch width and length, product characteristics and target output. Compatible multihead weighers, auger fillers and other dosing systems can be integrated for continuous pouch forming, filling and sealing.
