회사 소식 Is kraft tape the same as masking tape?

Here’s a breakdown of the key differences:

1. Primary Purpose and Function:

• Kraft Tape: This tape is engineered for permanent sealing and strength. Its primary job is to securely close boxes and packages for shipping, storage, or moving. It is designed to create a strong, durable hold that can withstand handling and transit without breaking.

• Masking Tape: This tape is engineered for temporary holding and protection. Its primary job is to mask off areas (like window frames or trim) during painting to create clean lines.

It is designed to be removed easily and cleanly after the task is complete without damaging the underlying surface.

2. Adhesive Properties:

• Kraft Tape: It uses a strong, aggressive adhesive—often rubber-based or acrylic-based. This adhesive is meant to bond permanently to surfaces like corrugated cardboard. Removing kraft tape will almost certainly tear the surface of the box or leave a very stubborn sticky residue behind.

• Masking Tape: It uses a pressure-sensitive adhesive with a much weaker tack. This adhesive is specifically formulated to hold securely yet release cleanly when peeled off. High-quality masking tape (like painter's tape) is defined by its ability to be removed without leaving any residue.

3. Backing Material and Strength:

• Kraft Tape: The backing is made from kraft paper, which is known for its durability and high tensile strength. Many kraft tapes are also reinforced with fiberglass filaments, making them incredibly difficult to tear by hand and highly resistant to snapping under tension.

• Masking Tape: The backing is made from a thin, crepe paper that is flexible and easy to tear by hand. It is not designed for structural strength; it is designed for conformability and easy application/removal.

4. Result of Removal:

• Kraft Tape: It is not meant to be removed. Attempting to remove it will result in a messy, difficult process that typically destroys the tape and likely damages the surface it was applied to.

• Masking Tape: Removal is its intended function. When pulled off, it should come away in one piece, leaving a clean, undamaged surface beneath it.

In summary: Think of it this way:

• You use kraft tape to seal a box you are shipping. You want it to stay closed until the recipient forcefully opens it.

• You use masking tape to protect a window frame while you paint a wall. You want it to hold just long enough for you to paint and then come off cleanly without pulling any paint off with it.
