2 and 3 Side Seal Pouch

2 Side Seal pouch is made folding the web along the larger side. The shorter side is sealed thanks to the sealing characteristics of the film internal layer.  This type of pouch is normally not big in size, but with good resistance and it is used to pack powders or semi liquid. 3 Side seal pouch is made folding the web along the larger side or using 2 different webs and then sealing the bottom and the 2 sides.


Bag-in-box

A Bag-in-Box or BiB is a type of container for the storage and transportation of liquids. It consists of a strong bladder (or plastic bag), usually made of several layers of metalized film or other plastics, sealed inside a corrugated fiberboard box. The bag is supplied to the 'filler' as an empty pre made bag. The 'filler' then generally removes the tap, fills the bag and then replaces the tap.
The primary purpose of the bag-in-box, when it was conceived in the '50s, was that for the transport of acid present in the batteries. Today the bag-in-box are widely used in the food industry and in particular the beverages (Eg it is widely used as a dispenser for wine and concentrates for juices).


Center-seal pouch

It is a pouch with a center seal running the full length of the pouch and seals forming both the top and bottom of the pouch. The sealing is done through heat sealing and can be either overlapped (in this case the material must have sealing characteristics on both sides) or fin sealed, making match the internal surface of the material used as a fin. In this way is possible to obtain a more robust seal, which is then folded on the body of the pouch.
The center-seal pouch may have two variants: the first as tubular flat pouch and second with side gussets; in both cases is always manufactured from a single film.


Cheer Pack

The Cheer Pack® pouch is a gusseted bag, featuring by an easy-flow straw with a reclosable, tamper-evident, screw-on top. The pouch is made from a multi-layer laminate material, with 3-4 layers in a standard configuration. An outer layer of glossy polyester is used to protect the printing. The next layer is selected based on the barrier properties required. An additional layer of nylon is added to increase the strength properties of larger package formats. The internal or final layer is a polyethylene or polypropelene sealing layer.
The Cheer Pack® is ideal for packaging squeezable liquids, gels, pastes and purees and is widespread used for energy drinks, beverages, sauces,…


Chevron Peel Pouch

These kinds of peelable pouches, called also see-through bags, are widespread used in the packaging of sterile medical products, especially hospitals and dentists or everybody wants to sterilize instruments or any other medical devices with steam or gas procedures. The chevron peelable pouch is composed by two separate films: the most popular  materials used are medical grade paper or Tyvek® (Dupont) for the back part of the pouch and a plastic film (clear film) composed by polyester/polypropylene for the face. Chevron pouches can also be made of a different polymer composition: it refers to these pouches generally as "film to film” or “foil to foil” and are not suitable for sterilization gas as both sides of the bag are made with non-porous materials.

Chevron pouches characterize by an entire peelable side with a seal pattern shaped like a back jean pocket. The sealing is multiline, continuous and has been affected to prevent risk of contamination during the stocking operations and when the pack is open: the final pack creates an effective barrier against bacterial penetration and allows aseptic presentation of the packed item. The identification of packed instruments is easy because of the transparent plastic film, moreover thanks to the colored paper film used; it is possible to visually control the seal integrity.


Corner peel pouch

These kinds of peelable pouches, called also corner peel bags, are widespread used in the packaging of sterile medical products, especially hospitals and dentists or everybody wants to sterilize instruments or any other medical devices with steam or gas procedures. The corner peelable pouch is composed by two separate films: the most popular materials used are medical grade paper or Tyvek® (Dupont) for the back part of the pouch and a plastic film (clear film) composed by polyester/polypropylene for the face. Chevron pouches can also be made of a different polymer composition: it refers to these pouches generally as "film to film” or “foil to foil” and are not suitable for sterilization gas as both sides of the bag are made with non-porous materials.

Corner peel pouches are used when it is desirable for the product fit close to the top seal of the pouch or for bulky products; the final pack creates an effective barrier against bacterial penetration and allows aseptic presentation of the packed item. The identification of packed instruments is easy because of the transparent plastic film.


Degassing valve

The one-way degassing valve (often called freshness valve, aroma valve, or coffee valve) consists of a valve placed on the pouch, which effectively vents CO2 gas build-up while sealing-out environmental oxygen, moisture and contaminants.
Degassing valves are widespread used for the packaging of roasted coffee mostly in side gusset bags and allows coffee to be packed immediately after roasting without the concern of coffee degradation.
Different types of degassing valves are present on the market: the inner valve is for example hidden beneath the laminate; the outer valve on the contrary is designed to be seen on the package surface. There are moreover most dedicated valves as for example high flow valves, high pressure valves, extra fin valves,…


Doypack

A Doypack® is a pouch that is designed to stand upright. Doypack® are commonly used for powders or ready to drink beverages. They can be aseptically filled or filled on normal packaging lines.
The Doypack® was invented in 1962 as a packaging for fruit juice and olives, by the French inventor Louis Doyen, president of Thimonnier Company. The trademark "Doypack" (from DOYen PACKaging) is filed internationally and is owned by Louis Doyen.

Flanged zipper

It is a system composed of two grooved and flanged strings to fit through pressure one inside the other ensuring proper closure
Flanged zipper contains, as the name suggests, the addition of flanges to the locking mechanism of the flangeless zipper. The flanged zipper is easier to attach to packaging materials and can be used to add functionality. For example, it can be used to adjust the locking strength of the zipper.
