Cushioning Material for Fragile Items: Corner Protection for Ceramic Products

Cushioning Material for Fragile Items must protect ceramics in more ways than just surface abrasion. A mug can arrive with an intact body and a fractured handle; a plate can arrive with edge chips despite multiple layers of wrapping paper.

Packaging failures are typically caused by localized impact, insufficient clearances, and uncontrolled movement within the carton. In assessing ceramic packaging at GT GROUP, we evaluate material deformation, load distribution and structural protection as opposed to wrap thickness alone.

Ceramic Corners Fail During Shipping

It is because of ceramic materials' propensity towards brittle fracture that the failure of ceramic packages during transit is extremely prevalent.

•The strength of a thin rim between a body of a ceramic package and a support surface may not be sufficient to support the load, and may fail by contact stress.

•Cushioning may not be sufficient to prevent ceramic packages from coming in direct contact with the rigid walls of the carton.

•Vibration during transit can cause ceramic packages to collide with one another, and with the carton walls.

Edge chipping can be controlled by surface wrapping. Corner and other load concentrating regions can be supported and protected by internal reinforcing members.

How Cushioning Material for Fragile Items Controls Impact

Inherent in all protective cushioning is the ability to compress and slow down the load being carried. Peak transmitted force and acceleration are also limited to an acceptable range.

Cushioning Thickness, Static Stress, and Compression

The range of static stress supported by cushioning materials is estimated by dividing the supported load by the effective bearing area. This determines the lower bound for use of cushioning materials.

However, for dynamic deformation to occur, cushioning should have a certain thickness to limit hard contact with the protected corners. The thickness of cushioning can be estimated by dividing supported load by the allowable stress of the cushioning material.

•Insufficient Give: The material may transfer the force before it has the chance to deform enough to absorb shock.

•Inadequate Recovery: The cushioning may gradually lose its thickness and effectiveness with continuous impact.

Paper grammage (GSM) does not typically correlate with shock absorption. Other elements like the type and geometry of the fibers, humidity and the thickness of the material may affect shock absorption.

Honeycomb Structure and Load Distribution

The honeycomb structure is made up of interconnected cells, providing flexible wrapping and spacing.

If compressed, the cells may deflect and shock may be absorbed through bending and buckling. The response is dependent upon the cell geometry and degree of expansion.

Honeycomb paper may help protect vulnerable ceramic corners, but dedicated supports may be needed as well.

Cushioning for Fragile Items

Different materials provide different protective functions. Buyers should identify the functions such as surface protection, impact protection and structural fixing.

Can Paper Cushioning Replace EPE Foam?

Paper cushioning, like EPE foam, may absorb shock and protect packages, but equivalency needs to be validated through package testing. For heavier ceramics, for example, some type of foam may be better than paper-based cushioning. Protection may also require some type of support and/or clearance.

Material cost has to be weighed against packing time, shipping weight, dimensional weight and verified damage rates.

Designing Protective Packaging for Different Ceramics

The correct Cushioning Material for Fragile Items depends on product geometry, mass, fragility, and distribution conditions.

Four Packaging Design Requirements

Identify vulnerable contact points such as edges, handles, protrusions, and thin wall sections.

•Avoid clearance issues. Allow sufficient space for the product to deform the carton, but leave enough clearance for product to product contact.

•Avoid collisions. Use individual product wrappings, separators and supports to prevent product collisions instead of relying on loose fill to prevent collisions.

•Confirm adequate layers. Determine adequate layer count for product through testing and/or accounting for material compression and product weight.

Settling loose cushioning may allow edges to come into contact with other product edges.

Prevent ceramic to ceramic contact is especially critical when cartons contain multiple product items.

Testing Cushioning Material for Fragile Items

It is not possible to guarantee packaging reliability based on material specifications alone. Therefore, we suggest performing a qualitative evaluation of cushioning and a quantitative evaluation of complete packages.

ASTM D1596 can characterize cushioning behavior, but results depend on specimen thickness, contact area, and loading conditions. They do not guarantee equivalent performance inside a finished package.

•Product condition: Edge chipping, hairline cracks, and fractures

•Cushion conditions: Permanent compression, displacement, or collapse

•Package condition: Divider movement, carton deformation, and loss of clearance

Humidity conditioning and repeated-impact evaluation are especially relevant when selecting paper cushioning for international shipments.
