What is Soft Packaging Bag

Benefits of Soft Packaging Bag
Protects your products
Flexible packaging features a multi-layer construction that keeps food safe, keeps oxygen out, and keeps aroma in. Each layer works to prevent and reduce spoilage by keeping products together, ensuring fresh food for you to enjoy. Flexible packaging is resistant to denting and breakage, so it protects products throughout the shipping process!
Reduces food waste
Flexible packaging simultaneously protects and extends the shelf life of products without the use of preservatives. As shelf life increases, food waste decreases. This is a key benefit, as food waste is a major challenge in the United States, where approximately 1.3 billion tons of food is thrown away annually. Visit this link to see how dramatic the impact is for a number of everyday foods stored in flexible packaging!
Material and resource efficiency
Compared to traditional forms of packaging, flexible packaging can be made with less material, so it conserves resources and contributes to sustainability. It also requires fewer trucks for shipping and uses less energy to transport. This means conservation begins before you even purchase it!
Sends less materials to landfills
Although some materials such as glass and steel are recycled at higher rates than flexible packaging, they are bulky and send more package material to landfills than flexibles. Because flexible packaging is lightweight, made with fewer raw materials than traditional forms of packaging, and has recycling capabilities, less plastic ends up in landfills!
Convenience is KING
Flexible packaging can go places that other packaging cannot. It is easy to open, carry, reseal, and store! You can easily throw it in your bag and take it with you on the go. Since it is lightweight and easy to store, it also saves space in your kitchen and throughout other areas of your home.
Reusable
Along with reducing food waste and being environmentally friendly, flexible packaging is also reusable! According to the U.S. EPA Waste Hierarchy, the most preferred method for waste management is using fewer resources to produce and reusing the packaging. There are many ways to reuse flexible packaging. Get started today by checking out our blog post for 16 ways to reuse flexible packaging.
Types of Soft Packaging Bag
Three-sside seal bag (flat bag pouch)
The three-side seal bag style is sealed on three sides and open on one side (sealed after bagging at the factory). It can keep moisture and seal well. The bag type with good airtightness. It is usually used to keep the freshness of the product and is convenient to carry. It is an ideal choice for brands and retailers. It is also the most common way to make bags.
Stand-up bag (doypak)
Stand-up bag is a type of soft packaging bag with a horizontal support structure at the bottom. It can stand on its own without relying on any support and whether the bag is opened or not. It has advantages in many aspects such as improving product grade, enhancing shelf visual effects, being light to carry and convenient to use.
Zipper bag
Zipper bag refers to a package with a zipper structure at the opening. It can be opened or sealed at any time. It has a strong airtightness and has a good barrier effect against air, water, odor, etc. It is mostly used for food packaging or product packaging that needs to be used multiple times. It can extend the shelf life of the product after opening the bag and play a role in waterproofing, moisture-proofing and insect-proofing.
Back-sealed bags ( quad seal bag / side gusset bags)
Back-sealed bags are packaging bags with sealed edges on the back of the bag body. There are no sealed edges on both sides of the bag body. The two sides of the bag body can withstand greater pressure, reducing the possibility of package damage. The layout can also ensure that the pattern on the front of the package is complete. Back-sealed bags have a wide range of applications, are light and not easy to break.
Eight-side seal bags / flat bottom bags / box pouches
Eight-side seal bags are packaging bags with eight sealed edges, four sealed edges at the bottom and two edges on each side. The bottom is flat and can stand steadily regardless of whether it is filled with items. It is very convenient whether it is displayed in the cabinet or during use. It makes the packaged product beautiful and atmospheric, and can maintain better flatness after filling the product.

Special-shaped bags refer to unconventional square packaging bags that require molds to make and can be made into various shapes. Different design styles are reflected according to different products. They are more novel, clear, easy to identify, and highlight the brand image. Special-shaped bags are very attractive to consumers.
Spout pouches
The spout bag is a new packaging method developed on the basis of the stand-up bag. This packaging has more advantages than plastic bottles in terms of convenience and cost. Therefore, the spout bag is gradually replacing plastic bottles and becoming one of the choices for materials such as juice, laundry detergent, sauce, and grains.
Process of Soft Packaging Bag
One of the most important processes to ensure that you pay great attention to is designing. This is where you get all the specifications from your clients to ensure you get it right before the manufacturing process begins. Some of the specifications may include adding their brand name, address, and the sizes they want to work with. Doing this beforehand saves you the stress of having to redo all the work if your client is not satisfied. Once you are done with the design, it should then be approved by the client to facilitate the rest of the processes.
The cylinder printing process is essential seeing as it provides the dye required for the manufacturing process. Each cylinder is meant to provide a certain color that you can work with. This goes to show that the number of cylinders being produced will depend on the design earlier created. You have to ensure that you get all the colors settled upon in the design stage and create the cylinders you’ll use. For some manufacturers, you’ll find that these cylinders are offered to the clients after the process is done. If that’s not the case, if the same client goes back for the same design, they’ll not have to add more money to cater for this step.
In this process, the printing cylinders are loaded onto the printing machine to begin the printing process. Once the printing cylinders are in place, a transparent polyester is loaded. The printing process can then begin to ensure that all the details are well articulated.
In this process, you have two choices when it comes to the type of lamination you’ll use. You could either use LD lamination or metallic polyester lamination. The lamination process ensures that the products produced are durable and of high quality.
After the lamination process, the Polyester is then loaded onto a slitting machine. This machine works to ensure that all the excess material is removed from the roll. This ensures that the roll is left smooth and without any rough edges.
Lastly, the rolls are loaded on to a pouch making machine which produces the final product. This is where the flexible packaging pouches and bags are finally produced for use. After this, they are then packed and delivered to the client as the final products.
Customization Options for Soft Packaging Bags

Fitments and closures
The first type of customization we will look at are the fitments and closures. These customizations contribute to the longevity of your product by determining how the pouch dispenses your product and whether it can be closed again. Popular options include:
Easy dispensing pouches with a tear notch are ideal for liquid, gel or lotion samples.
A tear notch or slit is a perforated top that allows for an easy opening process. You can also feature tear notches with other options like zippers for resealability.
Press-to-close zippers are an excellent and cost-effective option that allows your pouch to be conveniently closed and reopened.
Sliders are easy and fast to open and reclose. They offer your consumers the convenience and assurance that the pouch is closed correctly.
A spout pouch features a re-closable nozzle for easy access to liquid products.
Resealable films allow consumers to open and reseal a pouch using tamper-evident methods for safety and convenience.
A degassing valve is excellent for products like coffee that use stand-up pouches. The one-way valve vents CO2, allowing products to stay fresh for longer.
Tin ties add a quick way for consumers to close a pouch and are popular for baked goods.
Merchandising features
These customization options help display your pouch on store shelves and attract potential customers with convenient additions to your packaging. Options include:
Hang/peg holes that enable a pouch to be placed on hangars or hooks.
Display windows on a stand-up pouch lets consumers see the product inside the package.
Carry-hole handles provide an accessible and comfortable place for customers to carry a pouch bag without worrying about dropping it.


bARRIERS AND cOATINGS
Barrier and coating layers come in direct contact with the product and protect the pouch and its contents against contaminants by providing crucial barrier properties. These customizations improve packaging integrity and structure while increasing shelf life and preventing food waste. Barrier properties for stand-up and flat barrier pouches include:
Moisture Protection prevents food from losing moisture or protects against moisture for dry foods.
Grease Resistance/Grease-Proofing protects the package and maintains hygiene by resisting grease transfer from product to package.
Gas and Aroma Barriers prevent contaminants such as oxygen from entering a package and causing spoilage or prevent gasses from escaping.
Additional Heat Resistance gives a pouch extra resistance against hotter temperatures.
Typical coating materials to achieve the above barrier properties include aluminum foil, EVOH resin, transparent film, nylon, polyethylene terephthalate (PET), polyethylene (PE), and breathable or permeable barriers.
Material structures and layers
Pouches typically have multiple layers of material structure, all of which can be customized for different functions to market, protect, and preserve a product. Layers include:
The print/ink and coating layer is the outermost layer used for branding and design. It affects a package’s overall look and feel while providing product information to consumers.
Structural layers give a pouch its strength, durability and puncture resistance.
Barrier layers protect a product from odor, oxygen, light, and bacteria.
Sealant layers protect from leaks and provide functionality for other customizations like closures, fitments and resealability.
Tie layers are what bond structural and barrier layers together.
