How does bulk size impact the stability of a product during transit?

I have 2 bulks of emulsion (lotion, cream, yoghurt, sauce): 1kg and 0.030g. While in transit (plane and truck) the bigger bulk separated (oil pooled on top) and the smaller one stayed as is, with no changes to the appearance of the product.

In general, larger volumes of emulsion are more prone to instability and I understand the reason, but need some help in explaining it for a report. Something like stronger forces applied to the larger bulk and caused more stress, thus led to more strain?

Or do you think that in smaller volumes, the ratio of surface area to volume is higher?
Overall, what good engineering/physics explanation can anyone suggest here?

Thanks!

Temperature/thermal effects are usually(?) the culprits in "breaking" emulsions; smaller packages may be better insulated/more fluffily packed; less room to establish gradients. YMMV

Thank you, I can definitely add that aspect and elaborate more as I am familiar with it.
But I would like to know more about the impact of the shaking during transit as that part is more unfamiliar to me.

A lot may depend on the type of container: If it transfers vibration, especially resonant vibration, to contents, the frequency etc may induce separation / segregation rather than better dispersal...

Cue the old story of why eg Cornflakes and Muesli settle out faster in larger, 'Family Sized' packs...

You may need to cushion afflicted IBC with compliant mat / vibration isolators. IIRC, there are 'vanes' which may be fitted as internal dampers. Sorry, not my scene...

FAQ: How does bulk size impact the stability of a product during transit?

How does bulk size impact the stability of a product during transit?

Bulk size can significantly impact the stability of a product during transit. Larger bulk sizes often require more robust packaging and support to prevent shifting and damage. Smaller bulk sizes might be easier to stabilize but can lead to increased movement if not properly secured.

What are the common issues faced with large bulk sizes during transit?

Common issues with large bulk sizes include increased risk of tipping, shifting, and damage due to the higher center of gravity and larger surface area. Additionally, large bulk sizes may face challenges with fitting into standard transport containers, leading to inefficient space utilization and potential instability.

How can the stability of products with large bulk sizes be improved during transit?

Stability can be improved by using appropriate packaging materials such as reinforced boxes, pallets, and strapping. Additionally, using cushioning materials like foam or airbags can help absorb shocks and vibrations. Proper stacking techniques and securing the load within the transport vehicle are also crucial for maintaining stability.

Are there specific transportation methods better suited for large bulk sizes?

Yes, specific transportation methods such as flatbed trucks, rail transport, and cargo ships are often better suited for large bulk sizes. These methods provide more space and can accommodate larger and heavier loads more effectively. Additionally, specialized equipment like cranes and forklifts may be required for loading and unloading.

What role does weight distribution play in the stability of bulk-sized products during transit?

Weight distribution is critical for the stability of bulk-sized products during transit. Uneven weight distribution can lead to imbalances, increasing the risk of tipping and shifting. Ensuring that the weight is evenly distributed and properly secured helps maintain the center of gravity and enhances overall stability.
