Packaging heat failure isn’t something you usually notice immediately. One day you’re manufacturing product, packaging it, and shipping it out to a warehouse. All of the packages are sealed and appear to have a good bond. That is, until the boxes arrive at the warehouse. They’ve popped open and are no longer sealed. What occurred between the packaging of the product and its arrival at the warehouse?

In some cases, exposure to excessive heat is the cause. For many, what is the perfect excuse to lie by the pool or enjoy a day out on the lake, is the source of frustration for manufacturers and those involved in the packaging process. Packaging failures can cause downtime, returned product and packaging reworks, costing your plant thousands of dollars.
What Indicates Packaging Heat Failure?
If you suspect heat resistance failure, you’ll notice an oily residue and adhesive present on both sides of the substrate. One key point to remember is that the failure doesn’t occur during the manufacturing process, but rather after. This is usually during transit or storage.


Troubleshooting Case & Carton Failures- Heat Resistance


How to Solve Packaging Heat Failure
Resolving heat failure is as simple as identifying an alternative adhesive designed to withstand high temperatures. This solution is the best since it doesn’t require changing anything about your storage and shipping process. Changing to an adhesive with higher heat resistance will allow your boxes to endure hot conditions during storage and shipping.  

As always, we recommend working with an adhesive supplier to properly identify the issue.
