Pouches stand

In the lamination process, films of different materials are bonded using heat and/ or biodegradable adhesives [23, 34]. A metallized film (e.g., from PLA) with high barrier and stiffness can also be laminated on a Ecoflex /starch or Ecovio compound with good welding performance to produce e.g., a stand pouch for detergents.

Innovation in the fabric softener business not only focused on compositions, but also on packaging. As an alternative to plastic bottles, heat-sealed flexible polyethylene pouches were introduced to the market in the early 1980s [7], followed by several other containers free-standing flexible pouches with a solid base, different bag in a box rigid units, and refill cartons coated with chemically resistant polymers. These novelties led to a 40% reduction in plastic bottle consumption, the use of more biodegradable, renewable, easily recycled material, and a decrease in the packaging and distribution cost. New bottles made of 100% post consumer recycled plastic sandwiched between two layers of virgin resin also became available [7],... 

Pouches can be made in a variety of styles. However, the majority can be categorized into one of four groups pillow pouches, three-side seal pouches, four-side seal pouches, and stand-up pouches. 

Three-side seai pouches (Fig. 9.2(a)) contain two side seams and a top (or bottom) seam. The remaining side contains a fold. All seals are made between inner layers of the pouch material. If the pouch design incorporates gussets, these pouches can be capable of standing erect. In some applications, three-side seal pouches are used, but the side with the fold is also sealed, thus blurring the lines between three- and four-side seal pouches. 

The term stand-up pouch refers to a pouch that is able to support itself in an upright position when it is filled with product. Such pouches contain gussets that expand when the product is added, providing a relatively flat base to the pouch. Such pouches are increasingly replacing more rigid structures such as cans and bottles, for both dry products and liquids. 

Technological innovations in production of high barrier materials have also been important in the ability to use pouches for sensitive products. Many such pouches fall into the dual category of stand-up retort pouches, and will be discussed in Section 9.4.

These polymers are selected for the specific performance that they provide, and are combined in the final package design to meet all the requirements for the specific application in which they are being used. Often there are many different combinations of materials or film constructions that will meet the minimum performance requirements of an application. In these cases selection of the final packaging structure may be based on considerations such as availability from multiple suppliers and ability to provide differentiation over competitive packaging. For example a combination of a box and an inner liner may be used or a stand-up pouch may be used, each combination providing the minimum requirements for product protection and safety. One manufacturer may select to use a box and inner liner and other manufacturers may elect to package their product in a stand-up pouch for the same product. Or one manufacturer may choose to use a stand-up pouch and another manufacturer may choose to use a pillow pouch for the same product. 

Edible films are stand-alone thin layers of biopolymer materials. Films are generally used to determine the film properties, such as water vapor and gas barrier, mechanical properties, solubility, optical and other properties. Edible films are formed with less than 0.3 nun of thickness, while at higher thickness are called sheets. The films can also be placed on or between food components as a wrapper (McHugh, 2000) and they can be potentially formed as capsules, pouches, casings, and bags (Krochta, 2002). 

PP films are commercially available with different coatings (acrylic and PVEXT) to improve heat sealing, hanier, and optical characteristics, as well as to lower the coefficient of friction. Also, metallized PP films are available to provide extremely low values of permeability to gases and vapor." PP films are well suited for bag-in-box applications in cereals, crackers, soup mixes, and stand-up pouches. PP is also an excellent material to fabricate injection-molded closures for HDPE, PET, and glass bottles. 

Applications that benefit from these improved properties include gas barriers for bottles (beer bottles), food packaging (boil-in bags, stand-up pouches), fuel tanks, automotive applications, electronics and electrical applications (components, printed circuit boards), electrically conductive parts, wires, cables, and many others. Most major plastics companies and compounders are developing, manufacturing, and marketing such products.
