Choosing the right packaging for our products seems simple, but small details can lead to extra costs, damaged products or a poor customer experience. At Fxsanmartí, we have been manufacturing cardboard boxes for more than a century, and we have seen the same mistakes repeated time and again.
We explain them so you can avoid making them.
❌ Mistake 1: Choosing cardboard on price alone
The problem:
Choosing the cheapest cardboard without checking whether it suits your product. The result: boxes that deform, break or fail to provide proper protection.
How to avoid it:
Assess your product's weight, fragility and size. Not every item needs the same cardboard. Single-wall cardboard may be enough for lightweight products, while heavy or fragile products require double- or triple-wall cardboard. Weigh the cost of a damaged product against the saving on the box.
❌ Mistake 2: Overlooking the actual weight of the packed product
The problem:
Miscalculating the final weight (product + box + filling) can send shipping costs soaring or, worse, cause the box to give way during transport.
How to avoid it:
Test the complete package and always weigh it on scales. Make sure the chosen cardboard supports that weight without deforming. Our boxes are lightweight and strong, designed to optimise logistics costs.
❌ Mistake 3: Ignoring internal space or leaving the product too loose
The problem:
A product that moves around inside the box can suffer impacts and scuffing. An oversized box also increases shipping costs and requires more filling.
How to avoid it:
Measure your product carefully and add only the allowance needed (about 2–3 cm per side for protection). If the product needs extra protection, use suitable filling materials such as paper or bubble wrap. Remember: the perfect box protects without wasting space.
❌ Mistake 4: Forgetting the unboxing experience
The problem:
Many companies focus solely on protection and overlook how the customer receives the product. A box that is difficult to open or looks carelessly presented detracts from your brand.
How to avoid it:
Design your packaging with the person opening it in mind. Make it easy to open with tabs or pull tabs, pay attention to printing and visual finish, and ensure an enjoyable experience. Unboxing is the first physical impression of your brand.
❌ Mistake 5: Overlooking transport and storage conditions
The problem:
Boxes may encounter moisture, stacking, vibration or extreme temperatures during their journey. If you do not plan for these conditions, the product may arrive damaged.
How to avoid it:
Review the entire logistics chain: will the boxes be stacked? Could they get wet? Will they travel long distances? Choose cardboard suited to those conditions. If necessary, reinforce the corners or use special treatments such as varnishes or plastic coatings.
❌ Mistake 6: Failing to print the required information clearly
The problem:
Poorly printed or illegible instructions, barcodes, logos or legal warnings can confuse customers or lead to regulatory non-compliance.
How to avoid it:
Include all required information, such as origin, materials and recycling instructions. Use quality inks and check legibility. We use environmentally friendly inks and high-definition printing processes to ensure a professional result.
❌ Mistake 7: Misjudging delivery times
The problem:
Packaging is often the last thing ordered. If it does not arrive on time, production stops or sales are lost.
