A rigid box stands out in the packaging industry for its sturdy construction and ability to keep its shape. Companies often choose a rigid box when they need packaging that offers both protection and a premium look. These boxes do not bend or crumple easily. They use materials like rigid plastic, glass, or thick paperboard. The California Rigid Plastic Packaging Container Law describes rigid containers as those made entirely of plastic, designed to maintain their shape, and capable of at least one closure. Examples include buckets, pails, tubs, tubes, jugs, clamshells, and folding cartons. Many brands select custom rigid boxes for luxury products, electronics, or fragile items because these containers provide strong structural integrity and a high-end appearance.
Note: Rigid boxes often require more material and cost more to produce, but they deliver unmatched durability and product safety.
Key features of a rigid box:
Maintains firm shape and structure
Made from PET, HDPE, PP, PS, glass, or thick paperboard
Used for containers, bottles, trays, and clamshells
Offers durability, reusability, and a premium feel
A non-rigid container, also called flexible packaging, bends and adapts to the shape of its contents. This type of packaging uses lightweight materials such as LDPE, PE films, PP films, and PVC. Non-rigid containers include plastic bags, pouches, and shrink wraps. Companies favor flexible packaging for its affordability and ease of transport. These containers take up less space and reduce shipping costs. Unlike a rigid box, a non-rigid container does not provide the same level of protection or structure, but it works well for products that do not need extra support.

Tip: Brands that want to balance protection and sustainability should consider paperboard or recyclable plastics as their rigid stock choice.
The structure of a container determines its ability to withstand pressure, stacking, and handling. Rigid stock forms the backbone of rigid containers, giving them a solid, unyielding shape. Manufacturers use thick, layered materials such as chipboard, cardboard, and greyboard, sometimes reinforced with plastic fillings. These materials are glued together, creating a tough shell that does not bend or collapse. Rigid stock allows a rigid box to keep its shape even when empty, unlike flexible packaging, which lacks inherent structure.
Rigid containers use multi-layered construction for maximum strength.
Thick, non-bending boards act as a barrier against crushing and external forces.
Precision in cutting, grooving, and forming ensures the container maintains its shape and premium appearance.
The strength of rigid stock stands out in load-bearing tests. The following table compares the typical load capacities of rigid and non-rigid containers:
Container Type | Structure Characteristics | Typical Load Capacity (CFT) | Notes on Load-Bearing Capacity and Cargo Protection |
|---|---|---|---|
Dry Storage (Rigid) | Fully enclosed, rigid roof, walls, and floor | 20-foot: ~1,172 CFT | High load-bearing capacity due to rigid, enclosed structure |
40-foot: ~2,390 CFT | |||
Refrigerated (Rigid) | Enclosed with refrigeration unit | 20-foot: ~1,172 CFT | Similar load capacity, requires external power, rigid structure |
40-foot: ~2,040 CFT | |||
Open-Top (Rigid) | Like dry containers but with removable top | 20-foot: ~1,172 CFT | Rigid but open top requires tarpaulin for weather protection |
40-foot: ~2,390 CFT | |||
Half-Height (Rigid) | Half the height, robust for heavy bulk cargo | N/A | Designed for heavier loads with low center of gravity |
Flat Rack (Non-Rigid) | No rigid walls or roof, collapsible sides | 20-foot: ~1,154 CFT | Lower load capacity, cargo must be lashed and protected from weather |
40-foot: ~1,860 CFT |
Rigid stock provides the strength needed for containers to carry heavy loads and protect valuable goods. Non-rigid containers, which use flexible films, cannot match this level of strength or load-bearing ability. The robust nature of rigid stock significantly lowers the risk of damage during transit or storage. Quality materials and precise manufacturing help the container maintain its shape and appearance over time. Custom rigid boxes arrive pre-assembled, holding their shape without folding, which further enhances their strength and durability.
Product protection is a top priority for brands shipping fragile or high-value items. Rigid stock creates a sturdy shell that shields products from crushing, moisture, light, and air. This barrier preserves product integrity and extends shelf life. The thick, non-bending boards used in rigid stock act as a protective wall, reducing the risk of damage during shipping and storage.
Manufacturers test rigid containers using the ASTM D5276 drop test standard. This test involves dropping filled containers from controlled heights onto hard surfaces. Rigid containers, such as hard plastic jars, bottles, and glass jars, must withstand these drops without rupturing or losing contents. Regulations require that rigid large packagings be filled to near capacity and conditioned before drop testing. The container passes if it shows no loss of contents and no ruptures that allow spillage. These strict requirements ensure that rigid stock delivers optimum product protection during handling and transportation.
Non-rigid containers do not offer the same level of protection. Flexible packaging can bend or crumple, exposing products to external forces. Rigid stock, with its superior strength, stands out as the best choice for optimum product protection, especially for luxury, fragile, or high-value goods.
Tip: Brands seeking maximum strength and protection should choose rigid stock for their packaging needs.
