About three bottom style of spout packaging bag
In our daily lives, the use of barrier packaging and laminate materials has led to the widespread use of spout packaging bag for various products such as tea, powder, coffee beans, nuts, candies, and juice. However, it is important to note that not all spout packing bags are the same, as there are three basic types: round bottom, K-seal bottom, and plow bottom.
The round bottom type is the most common in the market, with its round bottom and corner welding edge providing support for the bag to stand on its own on the shelf. This type is suitable for lightweight products weighing less than 1 KG, and its standard size is usually small.
On the other hand, the K-seal bottom type is ideal for products weighing between 1 pound and 5 pounds. The bottom of the bag resembles the letter K, providing stability for the bag to stand while maintaining its aesthetic appeal. Molds are usually not required to make this type of spout package bags, and it is mainly suitable for powder or granular products.
Lastly, the plow bottom type, also known as corner bottom or folded bottom spout packaging bag, is recommended for products heavier than 5 pounds. The bottom is not sealed, and the product lies flat on the bottom of the pouch. This type has gained popularity in the food industry and is used for holding granular products such as salt and white granulated sugar.
It is important to note that the weight recommendations for each type of bag are based on experience and estimates. For specific bag choices, it is advisable to consult sales staff or take sample measurements according to individual needs.
In conclusion, the use of spout packaging bag has become increasingly prevalent in various industries, and understanding the different types available can help in making informed packaging decisions.
