A Complete Guide to Tapes Used in the Packaging Industry
Tape is one of the most essential yet often overlooked components in the packaging industry. From sealing corrugated boxes for shipment to protecting products against tampering and environmental exposure, the right tape plays a critical role in package integrity, efficiency, and brand presentation. This article explores the main types of tape used in the packaging industry, their materials, applications, and the advantages of each.
1. Carton Sealing Tape (Pressure-Sensitive Tape)
Carton sealing tapes are the most commonly used tapes in packaging operations. They are “pressure-sensitive,” meaning they adhere when pressure is applied—no heat or water required.
Polypropylene (PP) Tape
Polypropylene tape is the industry standard for most box-sealing applications. It is lightweight, cost-effective, and suitable for high-volume shipping.
Key features:
- Acrylic, hot-melt, or solvent-based adhesives
- Suitable for automated and manual application
- Ideal for lightweight to medium-weight cartons
PP tape is widely used in e-commerce, retail distribution, and manufacturing environments where speed and cost efficiency are priorities.
Polyvinyl Chloride (PVC) Tape
PVC tape is more durable and conformable than polypropylene, making it better suited for heavier cartons or irregular surfaces.
Key features:
- Smooth, quiet unwind (preferred in office or retail settings)
- High tensile strength
- Strong adhesion over a wide temperature range
Although more expensive, PVC tape is often chosen for premium or heavy-duty packaging.
2. Water-Activated Tape (Gummed Paper Tape)
Water-activated tape (WAT), also called gummed paper tape, is a paper-based tape that uses a starch or synthetic adhesive activated by water.
Non-Reinforced Paper Tape
Used primarily for lightweight cartons, this tape bonds aggressively to corrugated fiberboard and becomes part of the box itself.
Reinforced Water-Activated Tape
Reinforced WAT contains fiberglass filaments for added strength, making it suitable for heavy or high-value shipments.
Benefits of water-activated tape:
- Creates a tamper-evident seal
- Performs well in dusty or cold environments
- Often considered more sustainable due to paper backing
WAT is increasingly popular in fulfillment centers focused on security and sustainability.
3. Filament Tape (Strapping Tape)
Filament tape is reinforced with continuous fiberglass strands running lengthwise, crosswise, or in both directions.
Common applications include:
- Bundling products or cartons together
- Reinforcing heavy boxes
- Securing pallets or large items
Key characteristics:
- Extremely high tensile strength
- Resistant to abrasion and tearing
- Available in pressure-sensitive and water-activated versions
Filament tape is frequently used as a replacement or supplement to plastic strapping.
4. Masking Tape
Although not typically used to seal packages for shipment, masking tape plays an important role in packaging operations.
Uses include:
- Temporary holds during packing
- Labeling or marking cartons
- Protecting surfaces during manufacturing or finishing
Masking tape removes cleanly and is designed for short-term applications rather than long-term sealing.
5. Double-Sided Tape
Double-sided tape has adhesive on both sides and is used when a hidden bond is required.
Packaging-related uses:
- Attaching promotional materials or inserts
- Sealing envelopes, cartons, or mailers without visible tape
- Temporary positioning of products within packaging
It is commonly used in retail packaging, printed materials, and point-of-sale displays.
6. Foam Tape
Foam tape includes a compressible foam backing between adhesive layers.
Primary functions:
- Cushioning and vibration dampening
- Filling gaps between uneven surfaces
- Protecting fragile items during transit
Foam tape is often used in protective packaging, electronics, and specialty shipping applications.
7. Security and Tamper-Evident Tape
Security tapes are designed to show visible evidence if a package has been opened or altered.
Types of security tape include:
- Void message tape (leaves text when removed)
- Color-changing or destructible tape
- Custom-printed security tape
These tapes are commonly used for pharmaceuticals, electronics, confidential documents, and high-value goods.
8. Specialty Packaging Tapes
The packaging industry also relies on specialty tapes designed for specific environments or challenges.
Cold-Temperature and Freezer Tape
Engineered to adhere in low-temperature environments, these tapes are used in food distribution and cold storage.
High-Tack and Heavy-Duty Tape
Designed for recycled or dusty corrugated boxes where standard adhesives may fail.
Printed and Branded Tape
Custom-printed tape acts as both a sealing solution and a branding tool, reinforcing brand identity throughout the supply chain.
Sustainable and Eco-Friendly Tape
Includes paper tapes, recycled plastic tapes, and bio-based adhesives aimed at reducing environmental impact.
Choosing the Right Tape for Your Packaging Operation
Selecting the appropriate tape depends on several factors:
- Carton weight and material
- Shipping and storage conditions
- Level of security required
- Automation versus manual application
- Sustainability goals
Using the wrong tape can result in damaged products, increased returns, and higher operational costs.
Conclusion
Tape may seem like a small component of packaging, but its impact is significant. From basic carton sealing to specialized security and sustainability solutions, the wide variety of packaging tapes available allows businesses to optimize performance, protect products, and support operational efficiency. Understanding the different types of tape—and when to use them—is essential for anyone involved in packaging, logistics, or supply chain management.
