The field of food and beverage packaging has been exploring and looking for high-quality packaging solutions. Are you looking for different types of packaging materials? This article will analyze in detail the differences between different Beverage Packaging Bags. I wish you to choose the most suitable packaging material and type.

Ordinary plastic soft bags are a common packaging method in the beverage market. This type of packaging bag usually uses PE/PP/PA/PVC and other materials, a single-layer structure, general sealing, and a relatively affordable price. However, it should be noted that it does not have light-shielding and UV-resistant functions. This type of plastic soft bag is characterized by soft texture, lightness, translucency, and is also relatively fragile and easy to break.

Tetra Pak (Tetra Pak, Tetra Pak Pillow) is a Beverage Packaging Bag invented by Tetra Pak of Sweden. It is widely praised worldwide for its unique six-layer composite material structure. This packaging form covers a variety of types such as Tetra Pak Pillow, Tetra Pak Brick and Tetra Pak House, which are suitable for both pasteurization and UHT instant high-temperature sterilization. In Tetra Pak packaging, the cubic shape is a common form. Small-sized packaging often has a straw hole and comes with a sticky straw for easy drinking; while large-sized packaging mostly adopts a screw-on cap design to provide a convenient opening method. At the same time, the soft bag of Tetra Pak packaging is thick and durable. Compared with traditional packaging methods, the composite material structure of Tetra Pak packaging is its uniqueness, which includes multiple layers such as aluminum foil layer, PE layer and cardboard layer, each of which plays multiple functions such as insulation, sealing, support and strength. In addition, this material can also be printed, giving the packaging a more outstanding appearance. Tetra Pak pillow, as a packaging form with a very high cost-effectiveness, is deeply loved by the mid- and low-end product market and has become one of the most respected packaging solutions in the industry. 

Combibloc is derived from German technology and belongs to the Swiss SIG Group. As the biggest competitor of Tetra Pak packaging, Combibloc's market share in many regions around the world has even surpassed Tetra Pak. Its structure also adopts a multi-layer composite design, but the cost is more affordable. In terms of printing quality, Combibloc has demonstrated a differentiated competitive strategy from Tetra Pak, standing out with higher printing process flexibility. Although it feels more firm, it is slightly thin. Its large-size packaging is also equipped with a screw cap or a tear-off design like Huiyuan Juice, providing a convenient way to open. 

Plastic stand-up bags are also a commonly used Beverage Packaging Bags. This type of plastic stand-up bag is usually made of materials such as PP, PA or PET, has a single-layer structure, a thick texture, and relatively good sealing performance. Most plastic stand-up bags are designed with PET bottle mouths and screw caps for easy closure and carrying. The selection of these materials is mainly based on their physical and chemical properties to ensure the safety and stability of beverages during storage and transportation. Its unique bottom design allows the product to stand firmly. At the same time, its surface gloss is high and the printing process is fine, making the overall appearance more exquisite.

The PrePak bag, derived from the patented design of the French PrePak company, is known for its unique multi-layer composite structure. It is mainly made of PE material, and a black film layer is added to effectively isolate light and ultraviolet rays to ensure that the product is not affected by the outside world. For high-end products, an aluminum film layer is further used to provide a higher level of protection. They are usually presented as opaque soft bags with a relatively weak texture and easy to break. This packaging is widely used in dairy and plant protein drinks, especially in the mid- and low-end markets. 

The Shell Bag is a unique patent of Ecolean, Sweden, and is made of a composite material of PE and calcium carbonate. It is worth mentioning that calcium carbonate, which is the same main component of egg shells, is added to this material, so it is figuratively translated as "Shell Bag". Due to its unique environmental protection characteristics, this packaging is more easily degradable than other pure polyolefin packaging, making it highly anticipated in the market. This packaging presents the characteristics of a soft bag, and its overall shape is quite similar to a Western milk jug. It is particularly worth mentioning that it is equipped with an inflatable handle, and the design of the bottom is even more ingenious, which allows it to stand steadily.
