Made from multi-layer plastic films, laminated paper film, and aluminum foil lamination. The laminated film provides an extra protective layer to prevent the bag from being weakened by creases, and ensure the products in the 3 side seal bag have a long shelf life.

Three-sided seal bags are the most convenient packaging solution for various products. These bags have three welds when received by the customers, these welds or seals have two sides and a top or bottom. In this case, these bags would have one side open for the filling thereof. Once the bag has been filled, a heat sealer is used to seal the bag. These bags are useful for the packaging of a wide range of products.
Features of 3 Side Seal Bag
Package Uniformity
One of the most appealing aspects of the three-seal-sided packaging is that it can easily be customized to fit the brand's needs. Designers love this style because the front and back of the packaging serve as ideal spaces to service the brand's vision. There are endless options, like a matte or glossy finish. Thanks to companies who can print digitally, the design choices are as simple as uploading a PDF, allowing brands to experiment with looks and colors without costly plate setups in a traditional printing setting.
Economical Storage & Transportation
Another reason is they're easy to store after being shipped to a facility for filling and when it's time to ship the product out to stores or a consumer. The bags themselves are easy to stand in a box and ship with little concern due to their tough exterior.
Sustainable
Compared to many other packaging options, pouch packaging is a much more sustainable choice. They can be produced to be widely recyclable and easy for your customers to sort after consuming your product. They're less resource-intensive to produce, cheaper on fuel to transport, and they feed into the circular economy. You can learn more about this by visiting our sustainability page.
Easy to Fill
Due to the shape and flexibility of pouch packaging, they're easy to fill with products without wasting any space. Having a high product-to-packaging ratio reduces wasted packaging, helps to keep the total weight of your goods down, and can be less frustrating for your customers!
Durable
Pouch packaging is usually made from several protective layers which provide physical durability throughout their life cycle. Whether this is in a factory, stored in supermarkets, or while in your customer's hands, the pouch will retain its shape, print, and surface finish.
Suitable For Retail
Pouches are an ideal solution for retail products that stand on shelves or hang on railings. You can customize your pouch to stand on its own, lie flat, and add features such as euro-punched handles with ease. Pouches also stand out from the crowd and will help catch your customer's attention as they browse.
Material & Finish Choices
As pouches are made from several layers, you have a choice over what materials and finishes are used. Whether that's aluminum, kraft, clear, matt, or glossy finishes, you can customize your pouch to match your brand or product being stored inside. You can print directly onto the surface of a pouch, removing the need for additional packaging inserts to get all of your important information across. Pouch prints are high-quality and won't fade during their usage.
Types of Pouches




Three-Side Seal Pouches
These pouches are sealed on three sides, leaving one open for filling and sealing. They offer a sleek and minimalistic appearance, making them a preferred choice for products that prioritize simplicity and clean design. They are versatile and suitable for various products, from dry goods to liquids.
Gusseted Pouches
These pouches have expandable sides or a gusset that allows the bag to expand. This feature provides extra space for products requiring more room, such as bulk items or products with irregular shapes. They offer flexibility and efficient use of space that ensures optimal packaging for various products.
Flat Bottom Pouches
A flat bottom pouch has a flat base, which allows it to stand upright on shelves. It is suitable for heavier products and provides a larger display area for labeling and branding.
K-Seal Pouches
A K-seal pouch is a type of stand-up pouch that has a unique seal shape that provides extra strength and stability, making it suitable for heavy products.
Spout Pouches
A spout pouch is a stand-up pouch with a small plastic spout that can be used for dispensing products. It is commonly used for packaging liquids, such as sauces and drinks.
Zipper Pouches

Window Pouches

Biodegradable Pouches
Biodegradable pouches are made from materials that break down naturally in the environment, reducing waste and promoting sustainability.
Laminated Pouches
Laminated pouches are made by laminating multiple layers of materials to create a barrier that protects the product and extends its shelf life.
Food Packaging
3 side seal pouches are commonly used to package dry goods, such as snacks, coffee, and pet food.
Personal Care Products
These pouches are ideal for packaging personal care products such as wipes, facial masks, and hand sanitizers.
Pharmaceutical Packaging
3 side seal pouches are used in the pharmaceutical industry to package medications and medical devices.


Industrial Packaging
These pouches are used to package industrial products such as chemicals, lubricants, and adhesives.
Garden
The agricultural sector applies the use of these pouches to pack seeds, fertilizers, herbicides, and pesticides.
Pet foods
Manufacturers of pet foods use 3-side seal pouches of different sizes to package dry pet foods such as dog biscuits.
Farm Fresh

Surface Finishing Methods of 3 Side Seal Bag
Not only do humans naturally respond enthusiastically to shiny things, making it likely that your pouch will attract plenty of attention, but a gloss finish can also be used strategically to highlight key logos, words, or images on your packaging. In addition to its high shelf impact, packages with a gloss finish can handle scratches and smudges, as well as dust and dirt, to keep them looking great over time. Going for a glossy finish is perfect for anyone who's not as concerned about projecting an all-natural image as they are about catching consumers' eyes and hooking them with bold colors and artwork. For instance, a candy manufacturer who wants to express high-energy fun with their packaging might benefit from the durability and vibrancy of a glossy finish.
In locations like supermarkets, glossy and shiny packages are the norm, which means that a matte finish stands out to consumers. And with most supermarket consumers spending as little as 3 to 5 seconds making a decision about what product to buy, being able to stand out is absolutely crucial for the success of your product. Its contents s are perceived to be more natural. A recent study demonstrated that packaged food products were perceived to be more natural when they were in matte packages than when they were in glossy packages. These customers also expected the more natural food to taste better and were more likely to buy it.
If your brand is all about luxury, soft touch finishing may just be the perfect choice for your product. Soft touch finishing is used to give products a silky-smooth look and soft, velvety feel that will register with your customers as high-end signifiers. Additionally, because the surface of a soft-touch package has a minimal sheen and appears to be almost matte from a distance, it has all of the benefits associated with a matte finish, such as a sophisticated appearance and all-natural essence.
Spot UV printing is a great way to add a touch of upscale sophistication to your packaging. Because UV printing uses ultraviolet (UV) light to cure varnish in specific areas, it not only produces vibrant, high-sheen packaging but also can be used to target only specific spots or areas. By mixing and matching a spot UV finish with, say, a matte finish, you can end up with a premium, high-end blend of textures.
Metalization is an advanced printing technique where very specific areas of your bag or pouch have a metalized effect applied to them. Using metallic effects on your bag is a great way to showcase a specific design element of your bag, and provides a striking visual effect that is sure to catch the eye of your customers as they browse the shelves at the store. Whether you sell dog treats, cookies, cosmetics, or cannabis, metalized bags and pouches will be sure to make your customers curious about what's inside.
Process of 3 Side Seal Bag
Plate Making
The plate-making process is the process of manufacturing a printing plate that transfers ink to the printing material during printing. Through the dots made on the printing plate, the color of the original image is reproduced.
Printing
The printing process is the process of using substrates, printing plates, inks, and printing machinery to achieve graphic reproduction. The graphics and text on the printing plate will be transferred to the substrate. According to the types of printing plates: gravure, flexo, silk-screen, letterpress, and offset printing methods.
Quality Inspection
The quality inspection process is a process in which the printed semi-finished products are checked out and rejected by the quality inspection machine. Reduce the production loss in the subsequent process and the difficulty of quality inspection.
Compounding
The compounding process is to combine two or more materials to form an integrated material. Most of the flexible packaging is produced by the dry compounding process. During production, the glued substrate is discharged into the gluing device through the unwinding device. The glue on the surface of the glue roller is scraped off by the scraper, and the glue in the dots is on the glued substrate. When the pressing occurs, it is transferred to the surface of the glued substrate and then enters the oven. The solvent component in the glue is volatilized in the heated and blown oven.
Curing Process
The curing process is a process in which the main agent and curing agent in the composite film complete the reaction. The newly compounded composite product cannot enter the next process because the adhesive layer is not cured and set. Therefore, the main agent and curing agent must be cured through the curing process to complete the reaction of the main agent and the curing agent, and the adhesive layer is set. The maturation is divided into room temperature maturation and heating maturation.
Slitting
Slitting is the process of slitting the laminated composite film or the printed film that does not need to be composited into the required width. During production, the slitting material is discharged through the unwinding device, and the photoelectric control system controls the longitudinal travel position of the slitting material to keep the cutting knife position of the slitting product constant. The winding device winds the cut product into a roll film.
Bag Making
The bag-making process is a process of heat-sealing the composite film into a bag shape according to customers' requirements. The inner layer of the composite film must be a film with heat-sealing properties.
