Contradiction on flexible and rigid packaging

Both the options have their own benefits but there are no cons, it is just on the usage demand by the company.
Its a general term that means rigidity, which is sabotage or an individual’s capability to respond, grow and develop.
Over the two decades, flexible packaging has developed a lot. Since its origins as a single-use packaging, the most significant introduction to the pouch has been the cap, which allows opening and closing of the package with ease, while providing the product to continue conserved and well-stored.
