Rigid containers are solid, inflexible structures designed to hold and protect various types of materials, including liquids, solids, and gases. Common examples include glass jars, metal cans, and plastic bottles. These containers maintain their shape under pressure and are often used in packaging, storage, and transportation due to their durability and ability to provide a barrier against environmental factors. Their design ensures that the contents remain contained and secure during handling and shipment.
The uses of rigid polystyrene are containers such as cosmetic bottles, TV cabinets. etc. In its sheet form it is used to make disposable cups.
It depends on what the containers are made of. If they are made of very fine material that can be folded really small than possibly a few. But if they are rigid, then none.
See the links for a summary of the details of testing Rigid Plastic Containers which references IS 6312.
Flexible unit-load materials, like stretch wrap or shrink film, offer benefits such as reduced weight, increased flexibility in packaging shape and size, improved space utilization during transport and storage, and potential cost savings due to lower material and transportation expenses compared to rigid containers.
The growth of flexible bags, pouches, and wraps, as well as rigid carriers and containers made from plastics, has created a serious challenge to the dominance of the folding paperboard box.

Rigid is immovable, unbending. Semi-rigid can move in a limited way.
Model 1 containers could be made from glass or metal to ensure that they are nonflexible. These materials are rigid and do not deform easily under pressure, making them suitable for maintaining the container's shape without flexing.

no they are not rigid.
Rigid polystyrene plastic is a closed cell of light weight, rigid & foam plastic that is derived from petroleum and natural gas by products. It is hard plastic in one word. This is used to make plastic containers and insulators. On the other hand, expanded polystyrene is derived by expanding the regular foam molecules by 50 times their volume using a blowing agent (pentane gas). This is used to make packaging materials.
