Plastic Standing Pouch

What is Plastic Standing Pouch?

A plastic standing pouch is a flexible package made of plastic film that can stand up on its own due to its shape and design. It typically has a flat bottom, gusseted sides, and a ziplock or heat seal at the top for easy opening and closing. Plastic standing pouches are commonly used for storing and packaging food products, such as snacks, dried fruits, or powder mixes, as well as non-food items like pet food, cosmetics, or laundry detergents. They are lightweight, durable, and can be customized with various printing options to meet branding or marketing needs.

Advantages of Plastic Standing Pouch

Durability and strength

Stand up pouches are durable due to the materials used and the manufacturing process. Their strong, laminated, foil or plastic materials are less prone to tearing or puncturing compared to other packaging types, making them ideal for goods that may require that extra level of strength. They can withstand transportation, being filled with heavy products, placement in retail stores, and being handled by your customers.

Versatility

In addition to their durability, stand up pouches offer versatility in that they can be utilised for products of all types, shapes and weights. Whether that’s food items, such as nuts, supplements, fishing goods, pet food, cosmetics or just about anything else - stand up pouch packaging can be adapted and customised for a variety of products.

Convenience for retailers and consumers

Stand up pouches have a unique aesthetic that helps them stand out when they’re stored upright on shelves, lying flat, or hung on product railings. This makes it easier for retailers to display them and, in turn, easier for shoppers to find the goods they’re looking for.

Uniqueness

How you package your products can be the difference between attracting your customers’ attention and missing out on a sale. The customisation options allow you to create something truly bespoke that works for your product and brand. Even if your competitors are using pouches, the variations in size, shape, print and materials mean you’ll always have something unique on display.

Types of Plastic Standing Pouch

Gusseted pouches:Gusseted pouches are a variation on stand up pouches. With gusseted pouches, there are semi-oval shaped indents on both sides of the pouch which make for a square or rectangle base.This allows them to stand up but in a different fashion from traditional stand-up pouches. The tops of the bags often feature a different kind of resealability.The tops of the pouches are pushed together and then folded down repeatedly until they reach a section with a glue or other sticky material. The fold sticks to the glue and is sealed until your customer opens the pouch.When the seal is broken and then unfolded, two tabs can be revealed from the sides at the top of the pouch. The unsealed pouch can then be closed, folded back down, and the two tabs can be pushed over the fold to keep the bag sealed until next use.Some gusseted pouches feature package valves, which are small circular valves made of plastic. These valves allow oxygen and scent to escape the pouch. This prevents air from getting inside from the outside of the pouch. The point of these valves is two-fold.

Pillow pouches:Pillow pouches are one of the longest-running types of flexible pouches on the market. For decades products like potato chips, crackers, individual snack packs, single-serving coffee, and other types of smaller servings of food have been packaged this way.As one of the most affordable and straightforward pouches currently available, they are popular with many companies in the food industry, particularly those businesses that package snack foods such as chips and candy.
Their longevity in the market has made them exceptionally well known in households throughout the world. Pillow pouches come in resealable and non-resealable varieties.They feature heat seals at the top and bottom of the pouch. There is also a center seal that runs up the back of the pillow that has a short flap running vertically from the top to bottom seal. Some pillow pouches have a small die-cut oval shape on the top seal. This allows them to hang on metal pegs in a retail setting.

3 side seal pouches:Three side seal pouches are made of two pieces of metal foil or one side being a metal foil and the other clear plastic. This style of pouch is sometimes made of paper as well. The two sheets of material are placed on top of each other and then heat-sealed on three sides.The top or bottom of the pouch is left open for filling. Afterward, the pouch is completed with a tear-away lid. This makes it easy for the consumer to open the pouch after purchase.Three side seal pouches are often used for packaging beef jerky, spices, pet food, cannabis and other edible and non-edible products. Three side seal pouches can also be equipped with hang holes and resealable zippers similar to those found on stand up pouches.Three side seal pouches may be a good option for people looking for a sturdy pouch that allows for the consumer to see the product inside (if it has the clear window) and simple opening capabilities via a tear away lid.

Side gusseted pouches vs bottom gusseted pouches:Now when it comes to gusseted pouches, there are two main varieties: side gusseted pouches and bottom gusseted pouches. Side gusseted pouches are the ones usually used for coffee and feature the two flat panels on the front and back with the gussets on the left and right side.The flat panels on the back and front are where the central imagery, branding, and graphic art aesthetics are focused. The front panel is pointing outward on store shelves, facing anybody walking down the aisle. The back panel usually has text explaining the product, nutritional information, and consistent branding to the front of the pouch.Bottom gusseted pouches are generally larger than side gusseted pouches and can contain larger amounts of product. Bottom gusseted pouches have more shape and size possibilities than side gusseted pouches because they only have one gusset (on the bottom). This allows for the overall shape to be more fluid in design.

Material of Plastic Standing Pouch

They provide a great barrier against moisture, air, and other external contaminants, which keeps food fresh for a longer period of time.

Beauty and cosmetics

The beauty and cosmetics industry can greatly benefit from flexible packaging for products like shampoos, lotions, soaps, facemasks, and other products. The pouch’s flexibility and durability make them a great option for products that require a longer shelf life, are sensitive to light, and need to be protected from air and moisture.

Process of Plastic Standing Pouch

Material Selection

The first step in the process of making plastic standing pouches is selecting the type of material that will be used to manufacture the pouches. Common options include polyethylene (PE), polypropylene (PP), and polyester (PET), which are available in various thicknesses and finishes.

Printing

After the material has been selected, the next step is to print the design and branding onto the film. This is typically done using a flexographic printing press, which can print up to 8 colors at once.

Laminating

Once the film has been printed, it is laminated to a layer of adhesive or plastic film. This helps to ensure that the pouch is durable and moisture-resistant.

Slitting

After the film has been laminated, it is slit to the appropriate size and shape for the pouches. This can be done using a slitting machine, which uses a rotating blade to cut the film into strips.

Forming and Sealing

The final step is to form the standing pouch and seal the edges. This is typically done using a form-fill-seal machine. The machine forms the pouch by folding the film into the desired shape and sealing the edges using heat or ultrasonic welding.

Quality Control

Once the pouches are formed and sealed, they are inspected for quality control. This involves checking for any defects, such as air pockets, wrinkles, or misaligned seams.
