Bag Sealing Tape

Permanent Bag Sealing Tape?

is a pressure-sensitive tape designed specifically for permanently sealing bags and envelopes. It uses an extremely aggressive adhesive that creates an instant, high-tack bond to materials like plastic, paper, and cardboard. Once applied, the tape cannot be removed without cutting and destroying the bag.

It is composed of backing material such as PEPA,OPP, PET, HDPE, Aluminum film, Glassine Paper or other plastic films topped with hot melt and acrylic adhesive. They often have an easy-release liner that peels off to expose the adhesive. Tapes are available in various widths and thicknesses for different applications.

Key Features:

Bonds instantly and permanently
Destructive removal
Tamper-evident seal
Available in various liner materials, widths, adhesives
Easy-release liner

Types :

There are a few main varieties of permanent type tape:

Standard acrylic adhesive tapes for general use
Reinforced tapes for high-performance
Sizes 12mm, 15mm ,18mm and 25mm available
Custom adhesive formulations optimized for specific surfaces

Common Backing Materials

The most common backing materials used include:

Biaxially-oriented polypropylene (BOPP) – Excellent clarity, durability, strength
Polyethylene terephthalate (PET) – High tensile strength, temperature resistance
PEPA – Flexible, conformable
Aluminum foil – Excellent barrier, reflective, insulating
Glassine Paper – Cost Effectiveness, tear and heat resistance

Applications:

Permanent bag tapes are widely used in packaging and shipping operations such as:

Sealing courier bags/express bags/security bags
Sealing padded envelopes and bubble mailers
Tamper-evident seals on evidence, security bags

Resealable sealing tape is a kind of tape that can be used many times to seal and re-open plastic bags. It has different types of adhesive and material depending on the kind of plastic bag it is applied to. It can also have custom printing and anti-static features.

PE Sealing Tape

The PE sealing tape is a double-sided adhesive tape used for sealing plastic bags. It uses HDPE film as a release protective film, and is known for its easy tear feature, repeatable adhesion, and suitability for machine cutting and large-scale production of self-adhesive packaging bags. Our tape is made with a PET base material, making it more sturdy and less likely to break. Additionally, we use acrylic (acrylic acid) as the adhesive.
