Hello Packaging people,

I need some help of anyone dealing with liquid paperboard cartons, or customer keeps complaining about corner tears ( now this was done before I was at the company) putting a frozen smoothie in a paperboard carton. 

When asking evergreen they said it shouldn't be happening but they can not offer any solution.  I have increased the shipper ECT, lowered the TiHi. My last statement was to put it in a HG plastic bottle but we underfill it so I fear that would create more headache.

Thought?

Kyle, some questions first. 
- does this product ship frozen or ambient? 
- Did the exterior of the shipping case show any signs of compression damage from top load or impact? is there staining in the exterior of the shipping case? 
- how big of an issue is this? One carton in a pallet or multiples? 
- we use to pack millions of 64oz gable carton and it is rare to see this issue coming into your facility with this damage. 
- have you done instections on the production line to see if the issue is caused by something on the line? Potentially a stop or diversion mechanism on line? 
- hive are the cartons packed into the carton? Are they end loaded, wrap around, drop packed etc? 
- have you audited the production line to see if you can find this damage on line? Take a case every so often and 100% inspect for damages. 
- have you go out to the distribution centers and inspected pallet loads of product to see if you can find the issue. 

Overall, Evergreen has been making cartons for a long time and their quality is good. Unless you can see physical damages to the shipping case, my gut would tell me that this is being done by something on the production line. 

hope this helps, Bob

Hi Kyle,

Since this is meant to be a 6-ply structure, please check the PE layer thickness. If the PE is on the thinner side, it might be contributing to corner tears

One possibility is that the dieboard tooling used to form the box may be creating very sharp or deep creases.  I have a strong feeling this could be an issue! Under high filling pressure, those creases can become stress points and lead to tearing. After the creases are made, the supplier may be stacking them flat to manage space in pallets, which makes the corners vulnerable and punctures the crease. 

Another factor to consider could be the pH of the juice. If it's causing slight expansion of the pack, that added stress at the corners could be making them more prone to tearing.

Please let me know once this is resolved.
