The need for different modern packaging designs evolved because the previous ones caused leakages and spoilage of the products. This is because the packaging was loose and did not have a strong seal, so the moisture went inside and damaged the product. As the supply of products that have to be delivered on long routes increased, the demand for such packaging that could handle such long distances and keep the items fresh increased. This led to the production of back-heat-seal pouches that kept the products in the same condition. Thus, many brands prefer back-seal pouches in the USA. A wide range of businesses and industries use this, such as gourmet snacks, electronics, and even industries for storing their components. This bag preserves the food and also maintains brand identity.
The back-seal bag is rare and made up of a single sheet whose vertical ends are sealed together in the form of a tube so that the sealed and joined ends are on the back side of the bag. This creates a vertical seam at the back side of the bag and leaves the front side completely free. This gives a free canvas for designs to be printed on the front side without any barrier. The bottom and top of the bag are then sealed after the product is placed in them. This design is one of the very popular food-grade back seal pouches. Snacks, chips, biscuits, and many other products are used in this type of packaging.
There are two most popular types of back-seal food packaging bags. These are:
| Type | How it’s made | Best use |
| Fin seal | In this, the two vertical edges are joined together. They are sealed, and this creates a protruding flap on the backside of the bag. | Items that need strong protection, such as liquids. |
| Lap seal | In this, one vertical end of the sheet is overlapped and fused on the other side, thus leaving the back side flat. | Best when the printing on the packaging has to be break-free. |
This is usually made of three layers to give maximum protection. These are the layers and materials that they are made of:
This is made from Biaxially Oriented Polypropylene (BOPP) or Polyethylene Terephthalate (PET). This is the outermost layer and is made in such a way to protect the bag from heating.
This layer has aluminum foil or metallized PET (Met-PET). This protects the inner products from the outer environment.
The innermost layer has Cast Polypropylene (CPP) or Linear Low-Density Polyethylene (LLDPE) and is food-safe.
Plastic back-seal packaging bags are generally more used as compared to other types and styles of bags. Here is a comparison of other types with back-seal bags:
| Packaging type | Branding space | Material efficiency | High-speed machine compatibility |
| Back-seal bags | Uninterrupted panel | Very high | Exceptional |
| Three-sided seal bags | Bordered by side seams | Moderate | Moderate |
| Stand-up pouches | Broken by Bottom K-Seal | Low | Moderate |
The production of printed back seal bags is determined by complex industrial processes. These production methods help to make good-quality packaging tailored to your business needs.
High-speed machinery prints your tailor-made design onto the material from which back-seal bags have to be made.
This exterior, which is custom printed, is then attached to the middle and inner layers by strong lamination and adhesive.
The large-sized rolls are then cut to the specific width and size according to your requirements.
The ready-made orders are then passed through machinery for pouch-making lines. Here the heated bars apply thermal pressure to make a vertical center seal.
Most brands want minimal designs for their packaging. They prefer back-seal bags with logo, which gives their packaging a branded touch without overdoing it.
