Doy Style Stand Up Product BagsOur VFFS Packaging Machinery Produces Doy Style Stand-up Pouches
Doy Style and Stand Up Pouches
The Doy Pack style of stand-up pouches are popular for their strength and versatility in packaging a broad range of products, including powder, granules, pastes and liquids. The Doy Pack style stand-up pouch can achieve a greater filling volume then a flat pouch, and their ability to be displayed upright at point of sale offers an advantage in product marketing.
More recently the addition of resealable enclosures, such as zip sliders, added further benefit for product manufacturers by increasing the longevity of their products freshness after initial opening, giving further reason for the stand-up pouches growth in usage as a core packaging option.
All of the Line Equipment range of VFFS packaging machines are capable of producing Doy style stand-up pouches, with the added benefit/option of adding a resealable closure in conjunction with our Reseal 360 Crossweb re-seal zip applicator.
Doy Pack History
Louis Doyen, CEO of the French packaging machinery manufacturer Thimonnier, obtained a US Patent for a stand-up pouch design in 1968. This design still forms the basis of stand-up pouch design today. The basic Doyen design consists of two flat sheets seamed together along their sides, with a “W” fold running along the bottom and sealed to the tube wall with an upside-down U-shaped area. When the pouch is filled, the “W” (also called gusset) opens and provides a circular base on which the pouch can stand.

The Reseal 360 is the packaging industry’s leading trans-directional resealable zipper applicator. Using Zip-Pak® resealable transverse zippers from Zip-Pak®, it is the ideal cross-web technology, capable of running narrow or wider flange transverse zippers for bag resealability on vertical or horizontal form-fill-seal. Designed for simple and trouble-free installation, talk to Line Equipment packaging machinery about adding the Reseal 360 crossweb zip applicator to your existing host vertical form fill and seal bagging machine. All prospective host vertical form fill and seal bagging machinery will be inspected by qualified engineers to assess the level of refurbishment required and to maximise the compatibility of the Reseal 360 system.
