ARE YOU SEEING A RISE IN TAPE FAILURES?
Tape failures have been increasing due to the higher recycled content in corrugated boxes and uneven carton surfaces. Other factors include tape stretching, lifting, and stress from shipping and handling. AF2K testing can help identify weak seals and guide improvements before packages leave your facility.
Opensend reports that the number of packages compromised during shipping rose by 30% year-over-year, affecting 85 million parcels in 2024. Tape failures are a key reason for these compromised shipments, leading to delays, damaged goods, and customer dissatisfaction. Your distribution business might face returns, extra labor, and a damaged reputation when packages arrive compromised. Reducing tape failures protects products, improves reliability, and keeps operations running smoothly.
WHY ARE TAPE FAILURES INCREASING?
Tape keeps packages secure during shipping, protecting products from damage and tampering. When tape fails, it can lead to:
Product Damage |
Lost Items |
|
Delayed Delivery |
Returns & Rework |
Your distribution business needs to understand the causes of tape failures to take proactive actions. Identifying weak seals and addressing them early helps maintain reliability and reduces operational disruptions.

HIGHER RECYCLED CONTENT IN CORRUGATE
Boxes made with higher recycled fiber content often have rougher or uneven surfaces. Tape adhesive struggles to form a strong bond on these textures, making seals more prone to lifting, tearing, or failing under pressure.
Even small inconsistencies in the box’s surface can create weak points. These weak points increase the likelihood of compromised packages during shipping and handling.
INCONSISTENT CARTON SURFACE QUALITY
Not every box has a smooth, uniform surface. Several factors can prevent tape from sticking evenly, including:
- Texture
- Surface coatings
- Dust or debris
- Box finish
These inconsistencies create weak points along the seal, making it more likely to lift or peel. Uneven adhesion increases the risk of packages failing during handling or shipping.


TAPE STRETCHING AND LIFTING ISSUES
Improper tension or incorrect application can stretch tape, reducing its effectiveness and causing it to lift or pop. Even minor inconsistencies in placement or pressure create weak points along the seal.
These issues directly affect tape performance, leading to compromised packages and an increased risk of damage during transit. Ensuring consistent application helps maintain strong seals and improves overall shipping reliability.
SHIPPING AND HANDLING STRESS
During shipping, packages experience various stresses that weaken tape seals, including:
- Bumps
- Drops
- Vibration
- Compression
- Shifting
These forces test tape adhesion, often exposing weak seals that appear fine on the production line. Even minor weaknesses can lead to lifting, peeling, or complete seal failure, increasing the risk of damaged or compromised packages during transit.
