Packing Tape Essentials: A Comprehensive Guide
Packing tape is an indispensable tool for securing boxes, sealing packages, and ensuring safe transportation of goods. Whether you’re moving homes, shipping products, or storing items, choosing the right packing tape can make all the difference. This guide covers everything you need to know about packing tape, from types and materials to application techniques and industry standards.
Types of Packing Tape
Understanding the different types of packing tape available will help you select the most appropriate option for your needs:
1. Pressure-Sensitive Tape (PST)
The most common type of packing tape, PST adheres when pressure is applied. It typically features a polypropylene or polyester backing with a rubber-based adhesive. Ideal for general-purpose packaging and shipping.
2. Water-Activated Tape (Gummed Tape)
This tape requires moisture to activate its adhesive. When wetted, the starch-based adhesive forms a permanent bond with the cardboard. Often used for security purposes as it leaves evidence of tampering.
3. Filament Tape
Reinforced with fiberglass filaments, this tape offers exceptional tensile strength. Commonly used for bundling heavy items or reinforcing packages containing sharp edges.
4. Void Tape
Designed to leave a patterned residue when removed, void tape provides tamper-evident security for high-value shipments.
Key Material Considerations
The performance of packing tape depends largely on its material composition:
Backing Materials
- Polypropylene (BOPP): Most common, cost-effective, good for general use
- Polyester: Higher tensile strength, more expensive
- PVC: Flexible and weather-resistant
Adhesive Types
- Rubber-based: Strong initial tack, good for most applications
- Acrylic: Better temperature resistance, clearer appearance
- Hot melt: Excellent cold temperature performance

Selecting the Right Tape for Your Application
Consider these factors when choosing packing tape:
1. Box Weight and Contents
Heavier boxes require tape with greater tensile strength. As a general rule:
- Light packages (under 10 lbs): 1.6 mil thickness
- Medium packages (10-30 lbs): 2.0 mil thickness
- Heavy packages (30+ lbs): 3.0 mil thickness or reinforced tape
2. Environmental Conditions
For packages exposed to:
- Cold temperatures: Choose acrylic or hot melt adhesives
- High humidity: Water-activated tape performs best
- UV exposure: UV-resistant polyester tapes
3. Security Requirements
For valuable shipments, consider tamper-evident options like void tape or water-activated tape that bonds permanently to cardboard.
Proper Tape Application Techniques
Correct application ensures maximum holding power:
1. Surface Preparation
Ensure the box surface is clean
