Whats the usage of K seal bottom? Similar to the triangular stability theorem, the K-seal bottom enables the packaged product to support the stand up bag, which means the K-seal bottom helps the bag to be more stable. Besides, since there is like a one more sealing bessides the bottom sealing itself, the bottom will be firmer so that the powder inside wont be leaked easily. Whats more, since we seal the bottom, there wont be dead space for the left and right corners of the bag, it will be easier for customers to get the whey protein out, too.

Also besides the K-seal bag, we can do other bags for whey protein, like small daily use flat bag, common stand up zip lock bag, side gusset bag, eight side seal bag, and even spout bag. For spout bag, you can carry them instead of a bottle together with you when you go outside. Once you need to have some whey protein, just put the powder into it and pour water inside, then shake it, finally you can have it.
