In recent years, the main aseptic packaging forms in the Chinese market are: Bailibao, Tetra Pak/Tetra, Kangmei, plastic cups/plastic bottles.

Compared with these other packaging forms, plastic bag packaging has a greater comprehensive advantage:

1, aseptic plastic-based material bag packaging (commonly known as plastic bags) in the choice of their own material is relatively large. It can be a plastic co-extruded composite film, such as a three- and five-layer coextruded composite film commonly used in milk packaging, and can also be a plastic-based aluminized film, a plastic aluminum composite film, etc., which can be based on the shelf life of the packaged product, Appearance requirements, costs and other factors to choose the right packaging materials.

2, the plastic bag packaging size is more flexible, can be made into a variety of packaging bags, as large as a few hundred milliliters family packs large bags of beverages, as small as a few milliliters of promotional use of exquisite pouch drinks, to various types of consumers Larger choice of space, but also greatly facilitates sales; while plastic cups/bottles, Tetra Pak and SIG Combibloc are mostly fixed in a few specific capacity specifications subject to the constraints of their packaging materials and mechanical equipment, so that producers are not too More choice space.

3, plastic bag packaging because of its own characteristics of the material, can be processed into a variety of shapes to meet the packaging's appearance requirements (functional or packaging design appearance requirements), can also be used to attract the majority of new packaging shape The attention of the person and aroused their desire to buy. Plastic cups/bottles, Tetra Pak and SIG Combibloc are mostly fixed in their blow molding systems and forming systems. To change their initial settings, a large amount of capital is required to increase the cost and reduce profit margins.

4. The biggest advantage of plastic bag packaging compared with other packaging forms lies in its lower cost (including materials and filling equipment) and the existence of greater price advantage, and prices have played a major role in a large extent. In the absence of much difference in product content, product quality, product flavor and nutritional value, most consumers still choose plastic bag packaging.

5, plastic bags have good mechanical strength, not broken, can withstand extrusion. In other aseptic packaging forms, the mechanical strength is not very strong, and it is not too able to withstand too much compression and deformation. These deformations can occur during transportation and handling, which in turn affect their appearance and aesthetics, and are not conducive to sales.

The shelf life of plastic bags is generally around one month. According to the market research of relevant experts, the vast majority of long-term milk sold by the market is consumed within half a month to one month. And nowadays, the transportation is more and more developed, and the products produced can reach consumers' hands in a very short time. Therefore, although the shelf life of plastic bag packaging is relatively short, the sales of products are basically not generated. Great influence.

In short, considering synthetically, plastic bags have more advantages than other aseptic packaging forms in the Chinese market, which is more conducive to competition in the Chinese market environment.
