Why does tape peel off cardboard? Learn about the causes and effective solutions

You secure a package, set it aside, and a few minutes later notice that the tape edges are starting to peel dangerously from the cardboard. This situation directly affects the safety of the shipment and creates a risk of damage to goods during transit.

Instead of accepting this state of affairs, it is worth analyzing the technical aspects of adhesion so that every shipment leaves your warehouse in perfect condition and with a guarantee of lasting protection.

The most common reasons why tape loses its adhesion

Before assessing the quality of the tape itself, it's worth looking at external factors. Even a high-quality product may not perform its function if exposed to conditions for which it was not designed.

  • Cardboard dust: Cardboard, especially that made from recycled materials, tends to leave microscopic fibers and dust on the surface. These, like an insulating layer, separate the adhesive from the substrate.
  • Temperature and humidity: Damp cardboard or working in an unheated warehouse is a challenge for standard adhesives. In such conditions, the adhesive, instead of bonding with the cardboard, simply "hardens" and loses elasticity.
  • Improper storage: Dalpo tapes, like all professional tools, are best stored at room temperature. If the roll is frozen, its technical parameters may decrease.

What to do to prevent tape from peeling off cardboard?

1. Match the tape to the type of cardboard

Currently, the biggest challenge ispackaging made from recycled materials.Their porous structure means that standard tapes often lose contact with the surface. Even the strongest all-purpose tape may not be able to cope with the shorter fibers of recycled cardboard.

At Dalpo, after a series of specialized tests, we have prepared a solution dedicated to such tasks.Dalpo rPET 70% transparent packaging tapeis a product with a modified formula that we recommend for recycled cardboard. It guarantees the stability of the shipment where other solutions fail.

2. Proper pressure is key

Most packaging tapes are products thatactivate under pressure. Simply running your hand over it is often not enough. By using a professionalDalpo tape dispenser, you ensure even pressure along the entire length, which eliminates the risk of air bubbles and peeling edges.

3. Eliminate contaminants

Ensure that the cardboard surface is clean and dry. For heavy shipments, it is worth considering mechanical reinforcements. A high-strength solution isDalpo fiberglass-reinforced packaging tape.

4. Consider paper alternatives

If you are looking for a solution that permanently bonds with the packaging, the ideal choice will beDalpo paper packaging tapes. In particular,Dalpo water-activated paper tape, which penetrates deep into the cardboard fibers, creating a bond that cannot be removed without visible damage to the cardboard.

Pack with confidence and forget about peeling packages

Properly selected tape is not just a technical detail, but primarilythe basic protection of your goods. Choosing the right product will allow you to forget about the problem of peeling edges and unsightly packages. If you are planning to send unusual loads, it is also worth checking our tips onhow to properly pack a parcel.
