Introduction of Four Side Seal Packaging

Four-side sealing packaging is a kind of packaging form in which all the four directions of the seal are sealed up. It is generally divided into two forms: First, end sealing and cutting off four sides at the same time; and second, separated side sealing and end sealing. Four-side seal packaging equipment is mainly used in plasters, eye patches and other four-side sealing products. The equipment can be customized according to customer requirements, including notch type and location, multi-size products compatibility, easy product change, end seals numbers and forms.

Advantages of four side seal

A. Without 4 layers’ stacking, the sealability of four side seals is better compared to pillow packs.
B. Four side seals have a larger printing area and can be printed with explanatory text and other information.
C. Thin sheet products can be packaged in multiple rows to increase packaging speed.
D. The printing pattern will not be misplaced after the same roll of film being center-slit.

Industry Difficulties

With the rapid development of technology and economic, enterprises are more sensitive to the packaging appearance differentiation and cost. Four side seal has gradually became the preferred products of packaging equipment suppliers.
The main difficulty of four-side sealing is the lack of adaptability to the large-volume materials’ packaging. The whole film will be formed first before cutting so the formed bag is required to be relatively flat. And as a result, it is difficult to load large-volume materials. The utilization rate of the space in the bag is relatively low.
Meanwhile, four-side sealing requires a higher quality of heat sealing, thus realizing both the freedom of design in a larger layout and improving the aesthetics of the packaging products.
