4 Side Seal Pouch
When it comes to 4-sided Seal Pouch, the entire sheet of film is divided into two halves and then packaged relative to each other. Using heat sealing, the bags are first produced in an overall process, then individually cut. It only needs to be controlled on one side of the alignment to achieve a good packaging effect, so it is very adaptable to both package materials and equipment. Since each side is uniformly heat-sealed, the density of the product after bagging is better.
4-side Seal is still the main product of the mainstream packaging equipment suppliers in Europe, the main reasons are as follows: one is the pursuit of the quality of heat sealing and the second is the larger layout can be freely layout design, improve the aesthetics of the package. Especially for Europe and United States pharmaceutical companies, their use rate of more than 80 per cent.

What is the difference between a four-side seal bag and a three-side seal bag?
The disadvantage of four-side seal is the lack of adaptability to the packaging of large volume, due to the whole sheet of film first bag making and then cutting, bag body is flat after bag making, it is difficult to load the large volume of materials. The three side seal is commonly used in large volume packaging, three side seal is not as beautiful as the four side seal.
What is the difference between a four-side seal bag and a back seal bag?
Back-seal bags originated from Japan, with huge initial investment in equipment and high operation and maintenance costs. Because of the high difficulty of heat sealing, the bag sealing is lower than the four-side seal bag, and the risk of bag sealing failure is significantly higher than that of the four-side seal bag. The advantage is that it can be loaded with larger volume products.
