Corrugated boxes play a vital role in protecting products throughout shipping, storage, and retail display. When cartons begin to fail, the results can include damaged products, unhappy customers, increased shipping expenses, and unnecessary waste. Fortunately, most packaging failures have clear causes that can be identified and corrected.
At Shrink Packaging Systems Corp. (SPS), helping businesses improve packaging starts with evaluating how products move through the supply chain. Through our expertise in Material Overview, SPS helps customers select materials and designs that improve performance while controlling costs.
Common Causes of Crushed Corrugated Boxes
One of the most common packaging failures occurs when corrugated boxes lose their strength during shipping or warehouse storage. Crushed cartons can damage products, create unstable pallet loads, and increase product returns.
Several factors often contribute to this problem:
- Choosing a board grade that is too light for the product’s weight.
- Stacking pallets higher than the cartons were designed to support.
- Exposure to excessive humidity that weakens paper fibers.
- Uneven pallet loading that concentrates weight on certain boxes.
Rather than simply increasing material thickness, SPS evaluates the entire package design to determine whether stronger board grades, improved box styles, or different material combinations would provide better long-term performance. Customers can also learn about available corrugated options through the company’s cartons and corrugate resources.
Weak Seams Can Lead to Product Damage
A corrugated box is only as strong as its joints. When seams split during handling, products may become exposed or fall from the package before reaching their destination.
Common causes include:
- Improper adhesive application during manufacturing.
- Manufacturer joints that are not designed for the product’s weight.
- Cartons that are too small or too large for the contents.
- Excessive stress created during pallet stacking.
Evaluating seam construction often reveals opportunities to improve carton strength without significantly increasing packaging costs.
Moisture Can Significantly Reduce Carton Strength
Paper-based packaging performs extremely well under normal conditions, but moisture remains one of its biggest challenges. Even quality shipping boxes lose strength when exposed to excessive humidity or water.
Warning signs include:
- Soft side panels.
- Sagging cartons.
- Warped flaps.
- Reduced stacking performance.
Possible improvements include:
- Selecting moisture-resistant board grades.
- Improving warehouse climate control.
- Protecting pallets during transportation.
- Choosing packaging materials designed for humid environments.

Products That Shift Inside the Box
Even when the carton remains intact, products that move during shipment can suffer scratches, breakage, or other damage.
This typically occurs because:
- The shipping box is oversized.
- Interior cushioning is inadequate.
- Products are not separated properly.
- Empty space allows movement throughout transportation.
Corrugated box inserts help stabilize products inside the carton, reducing movement while improving overall protection. SPS frequently works with customers to evaluate insert designs that improve performance without adding unnecessary packaging material.
Poor Print Quality Can Affect Your Brand
Packaging does more than protect products. It also represents your brand every time a customer receives or sees your package.
Print quality problems may result from:
- Inappropriate printing methods.
- Poor ink selection.
- Low-quality corrugated surfaces.
- Manufacturing inconsistencies.
Custom printed corrugated boxes help businesses improve shelf appearance while maintaining structural performance. High-quality printed corrugated packaging is especially valuable for retail-ready packaging, where presentation directly influences purchasing decisions.
The Wrong Box Design Creates Unnecessary Problems
Sometimes the issue is not the material at all. The carton simply may not be designed for the application.
Examples include:
- Shipping boxes that are larger than necessary.
- Boxes that place excessive pressure on the product.
- Standard cartons are being used where die-cut corrugated boxes would perform better.
- Inefficient designs that waste material and shipping space.
Rather than relying on stock packaging, SPS helps customers evaluate designs that better match their products, distribution methods, and storage environments.
Heavy Products Often Require Specialized Corrugated Packaging
Products with greater weight or unusual dimensions often require stronger packaging systems than conventional corrugated boxes.
Depending on the application, solutions may include:
- Reinforced shipping boxes.
- Corrugated bulk containers.
- Heavy-duty corrugated packaging solutions.
- Custom-engineered die-cut corrugated boxes.
Selecting the appropriate package design helps reduce damage while improving handling throughout the supply chain. corrugated
How SPS Helps Improve Corrugated Packaging Performance
Every product has unique packaging requirements. Product weight, shipping distance, warehouse conditions, and retail display all influence carton performance.
SPS helps businesses improve packaging through:
- Material evaluations based on real-world distribution conditions
- Recommendations for stronger corrugated packaging solutions
- Assistance in selecting shipping boxes and retail-ready packaging
- Design support for custom printed corrugated boxes
- Development of corrugated box inserts and die-cut corrugated boxes
- Guidance for printed corrugated packaging and corrugated bulk containers
- Ongoing education through comprehensive operator training and support
Instead of relying on trial and error, SPS uses a practical, consultative approach to improve packaging performance while controlling material costs.
The Right Expertise Can Help
Most carton failures can be traced to incorrect material selection, poor package design, environmental conditions, or shipping practices. Identifying these issues early can reduce product damage, improve customer satisfaction, and lower packaging expenses throughout your supply chain.
