Vertical form & seal
Our family of vertical bagging machines includes models for both mid-range and high-speed packaging as well as small or large bag sizes. Both the VerTek® and XPdius® series of vertical form fill and seal machines are engineered to seal a wide variety of film types, structures and styles.
We have installed hundreds of vertical form fill and seal machines around the world for a variety of products including candy packaging, snack food packaging, chocolate packaging, vegetable packaging, fruit packaging, cheese packaging, meat packaging, poultry packaging, pet food packaging, bakery packaging, cannabis packaging, hemp packaging, vitamin gummy packaging, pharmaceutical packaging, medicinal packaging, frozen food packaging and grain packaging.
How does vertical form fill and seal technology work?
The vertical form, fill and seal process (also known as VFS or VFFS or vertical bagging) starts with a cylindrical roll of film. The vertical bagging machine will transfer film from the roll through the forming collar (aka tube or plow). Once transferred through the collar, the film will then fold and the vertical seal bars will extend to seal the back of the pouch. Once the desired pouch length is transferred and filled with product, the horizontal seal bars will then close, seal and cut the pouch providing a finished product with top and bottom horizontal seals and one vertical back seal.
