seal design

As we all know, once some food packages are opened, the food inside is easy to damp and deteriorate just because it’s exposed to the air and we can’t seal the open place again. So we should consider this shortcoming when we design the package. A solution to this problem is that using the two angle folds in the seal place and folding them inside after we getting the things inside. Combined with the way traditional Chinese packing drugs, this method can avoid air to enter effectively and keep the food flesh.
