Can you use any tape on a package USPS?

When mailing packages through the United States Postal Service (USPS), it’s important to use the right kind of tape to properly seal the package. Not all tapes are created equal when it comes to shipping. The tape you use needs to be strong enough to withstand the automated processing machines used by USPS.

Quick Answers

Here are some quick answers to common questions about using tape on USPS packages:

• No, you cannot use just any tape on packages sent via USPS. They have guidelines on proper tapes to use.
• Recommended tapes include pressure-sensitive plastic tape, water-activated paper tape, and reinforced kraft paper tape.
• Avoid using cellophane tape, duct tape, masking tape, or string to seal packages.
• Tape should be at least 2 inches wide for sealing seams and 3 inches wide for reinforcing edges.
• Apply tape evenly and securely, with no wrinkles or bubbles, sealing entire seams and overlaps.

USPS Guidelines on Tape

The United States Postal Service provides guidelines on which types of tapes can and cannot be used for sealing packages processed through their system. Here are some key points from the USPS regulations on tape:

• Pressure-sensitive plastic tape with a minimum thickness of 1.5 mils is recommended for sealing and reinforcing packages.
• Paper tapes such as water-activated paper tape and reinforced kraft paper tape can also be used.
• Cellophane tape, duct tape, string, and masking tape are all prohibited by USPS due to not being secure enough.
• Tapes should adhere firmly to surfaces without curling, wrinkling, or bubbles.
• Sealing tapes must be at least 2 inches wide; reinforcement tapes must be at least 3 inches wide.
• Tapes must extend at least 6 inches onto each side of the package for proper adhesion.

Following these guidelines ensures your package can withstand the rigors of automated USPS processing without coming undone. Using substandard tape greatly increases the chances of a package failure.

Recommended Tapes

Based on the USPS requirements, here are some of the best tape options for sealing your packages:

Pressure-Sensitive Plastic Tape

This is one of the best all-purpose options as it meets all the USPS guidelines. The plastic material and pressure-sensitive adhesive allow it to adhere firmly to different surfaces. Look for tape that is at least 2 inches wide for seams and reinforced 3 inch wide tape for edges.

Water-Activated Paper Tape

Water-activated paper tape provides a secure seal and the paper construction allows for easy recycling. It provides a good alternative to plastic tape. Apply water or a wet sponge to activate the adhesive. Using reinforced kraft paper tape gives it added durability.

Reinforced Kraft Paper Tape

For heavier packages, a reinforced kraft paper tape is a good option. It has a strong paper backing with reinforced yarn or fiberglass filaments for added strength. Make sure to apply adequate pressure when sealing with this tape.

Tapes to Avoid

On the flip side, here are some common tapes that should be avoided for USPS packages:

Cellophane Tape

While easy to use, cellophane tape does not have the adhesive strength needed for shipping packages. It can easily detach in transit.

Duct Tape

Duct tape seems sturdy but it lacks enough adhesion to consistently hold shipping boxes sealed. The adhesive can fail when packages are processed on high speed conveyor systems.

Masking Tape

Masking tape, designed for painting projects, does not provide a reliable seal for shipping. It can easily peel off during handling and transportation.

String

While sometimes used for wrapping packages, string is prohibited by USPS because it can get caught in processing machinery. Only appropriate tapes should be used.

Proper Tape Application

Using the right tape is only half the battle – it also needs to be applied properly to work effectively. Here are some tips for applying tape to packages for USPS:

• Clean all box surfaces before applying tape and ensure surfaces are dry
• Place tape evenly over seams with no wrinkles or bubbles
• Press down firmly along the tape edges to maximize adhesion
• Extend tape at least 6 inches onto each side of box
• Cover corners and seams with 3 inch reinforced tape for strength
• Consider using a tape gun applicator for even, consistent tape placement

Taking the time to carefully seal the entire box with quality tape will ensure it stays closed throughout the shipping process.

Special Tape Considerations

For some types of packages, you may need to take special precautions when it comes to taping for USPS shipping. Here are some examples:

Irregular Shaped Items

For oddly shaped items that require a box with flaps and seams at various angles, be sure to seal all the edges, corners, and gaps with 2-3 inch reinforced tape for maximum sealing.

Heavy Items

A heavy item in a box puts added stress on the seals. Use 3-4 inch wide reinforced kraft paper tape or plastic tape on the seams and corners to distribute the weight.

Liquid Filled Boxes

When taping a liquid filled box, tape over the seam where two flaps meet for double protection against leaks. Plastic seam sealing tape works well for this.

Perishable Items

If shipping perishable items, moisture resistant reinforced kraft paper tape adheres better to cardboard than plastic tape. This prevents seals failing if condensation forms.

FAQs

Can you use packing tape for USPS packages?

Yes, standard plastic packing tape is acceptable if it is a pressure-sensitive type and at least 1.5 mils thick. Ensure the tape width is at least 2 inches for sealing seams.

What kind of tape does USPS recommend?

USPS recommends pressure-sensitive plastic tape at least 1.5 mils thick or paper tapes such as water-activated or reinforced kraft paper that meet their adhesion standards.

Does USPS prohibit any types of tape?

Yes, USPS prohibits using cellophane tape, duct tape, masking tape, string, and other substandard tapes to seal packages based on their potential to fail.

Can you reuse boxes with old tape?

No, old tape should be removed from recycled boxes and new tape should be applied to ensure adequate adhesion. Old tape can lose integrity over time.

Is reinforced tape required for USPS packages?

Reinforced tape is not required but is highly recommended for sealing the edges and corners of packages as added protection against seam failures.

Key Takeaways

• Use only approved tapes for USPS like pressure-sensitive plastic, water-activated paper, or reinforced kraft paper.
• Avoid cellophane, duct, masking tapes and string that lack proper adhesive strength.
• Apply tape evenly and firmly over entire seams and overlaps.
• Reinforce edges and corners with 3 inch wide tape.
• Make sure tape extends at least 6 inches onto each side.
• Follow special taping tactics for heavy, liquid filled, or irregular boxes.

Following USPS guidelines and best practices for applying mailing tape will minimize chances of packages failing in transit. Take the time to properly seal all boxes and packages using quality tapes designed for shipping for best results.

Conclusion

Sealing packages properly for shipping via USPS requires using approved tapes designed to withstand transit and automated processing. Pressure-sensitive plastic tape and reinforced kraft paper tape are recommended for meeting USPS standards. Special care should be taken when taping irregular shaped, heavy, and liquid filled packages. Avoid inferior tapes like cellophane and duct tape that can fail. Following USPS guidelines and taping best practices ensures your packages make it to their destination securely sealed.
