How Does Resealable Bag Sealing Tape Work?

Resealable bag sealing tape uses two adhesive functions.

During bag manufacturing, one side of the tape is permanently bonded to the plastic bag. The opposite adhesive side allows the bag flap to be closed, opened and closed again.

This is different from permanent bag sealing tape, which is designed mainly for one-time closure.

For packaging that consumers may need to open several times, such as garment bags, stationery bags and accessory bags, resealable tape provides a more convenient closure solution.

Why Use BOPP Bag Sealing Tape for PE Bags?

When choosing bag sealing tape, it is important to match the liner construction to the bag film. This is especially important when the bag is produced using hot-cutting equipment.

BOPP resealable bag tape is commonly used with PE bags in hot-cut production because BOPP film offers good dimensional stability and resists deformation during processing better than many PE liner constructions.

Using a release-liner material that differs from the bag film can also help reduce the risk of the liner melting or sticking to the bag during cutting.

Main Features of Double Sided Resealable BOPP Bag Tape

Reliable Resealable Performance

Designed for bags that need to be opened and closed repeatedly without replacing the sealing tape.

Double-Sided Acrylic Adhesive

Acrylic pressure-sensitive adhesive provides stable bonding and clean application for compatible plastic packaging films.

Easy-Peel Finger Lift

An extended liner or finger-lift design makes the protective film easier to grip and remove during packing and final use.

Suitable for Automatic Bag Making

Long-length rolls can be integrated into continuous bag-manufacturing processes and help reduce roll-changing frequency.

Roll Format

Pancake and spool-wound formats are available for manual, semi-automatic and automatic bag-production lines.

Hot-Knife Cuttable

Suitable tape constructions can be used with hot-knife cutting processes commonly used for PE, HDPE and PP bag films.

Waterproof Bag Tape

The acrylic adhesive system provides reliable performance for normal plastic packaging applications exposed to moisture.

Clean Appearance

The narrow sealing strip integrates neatly into transparent plastic bags without significantly affecting the appearance of the finished package.

Available Tape Sizes

The standard Alibaba-listed specification for this tape is:

12/5/7 mm × 1540 m

The sizing format typically represents:

Film / liner width: 12 mm

Adhesive track A: 5 mm

Adhesive track B: 7 mm

Roll length: 15,400 meters

Other widths and adhesive-track combinations can be made to fit your bag design and bag-making machine. Common bag-sealing-tape widths in the market range from approximately 8.5 mm to 18 mm, with different A/B adhesive-track widths and left, right or center glue positioning available for different applications.

Custom Sizes

Send us your bag material, bag thickness, tape width, glue direction, machine type and required quantity, and we can recommend a suitable size specification.

---

Left Glue or Right Glue - Which One Do You Need?

Bag sealing tape can be manufactured with the adhesive track positioned on the left, right or center. The correct direction depends on how the tape feeds through your bag-making machine and where the sealing strip needs to sit on the finished bag.

Left Glue

Used when the adhesive track needs to be positioned toward the left side according to the feeding direction of your bag-making machine.

Right Glue

Used when the adhesive track needs to be positioned toward the right side according to the feeding direction of your bag-making machine.

Center Glue

Center adhesive tape is available for selected constructions and special bag-making-machine requirements.

To determine the correct glue direction, confirm:

Film feeding direction

Bag flap direction

Tape applicator position on the bag-making machine

Bag-making machine configuration

Location of the sealing strip on the finished bag

Not sure which direction you need? Send us a photo or drawing of your current tape and bag-making machine, and we can help identify the appropriate configuration.

Resealable Bag Tape vs. Permanent Bag Tape

Feature	Resealable Tape	Permanent Tape
Open Again?	Yes	Normally not recommended
Reclose Bag?	Yes	Not recommended
Main Use	Consumer / retail packaging	Courier / security bags
Typical Bags	Garment, stationery, retail bags	Courier, express, mailing bags
Adhesive Type	Permanent + removable/resealable adhesive	Permanent + permanent adhesive
User Experience	Easy access after initial opening	Security seal until final opening

Resealable tape is generally the better choice when customers need repeated access to the contents. Permanent tape is more suitable when the package should remain sealed until final opening.

Bag Sealing Tape for Automatic Bag-Making Machines

Our double-sided resealable bag sealing tape is suitable for manufacturing self-seal plastic bags on automatic production lines.

Before placing an order for automatic production, please confirm:

Bag material: LDPE / HDPE / other

Bag film thickness

Tape width

A/B adhesive width

Left or right glue position

Roll length

Core size

Maximum roll diameter

Bag-making machine model

Hot-knife or cold-knife cutting

How to Choose the Right Bag Sealing Tape

Step 1: Identify Bag Material

PE bags and PP/OPP bags may require different bag sealing tape constructions. BOPP resealable tape is a common solution for PE bags, particularly in hot-cut production.

Step 2: Confirm Bag Film Thickness

Film thickness, surface coatings and additives can affect adhesive performance. Testing the tape on your actual production film is recommended before placing a large order.

Step 3: Determine Glue Direction

Confirm whether your production line requires left glue, right glue or another adhesive position.

Step 4: Confirm Tape Size

If you already use bag sealing tape, send us a photo of the existing roll or provide the current specification.

Step 5: Test Ahead of Time

After the likely tape construction has been identified, test it with your actual bag film and equipment before bulk production.

Sample testing should confirm:

Adhesion to the actual film

Peel performance

Resealing performance

Machine feeding

Hot-knife cutting performance

---

Storage Guidelines

For best performance:

Store the tape in its original packaging until ready to use.

Keep the tape in a clean, dry indoor environment.

Avoid direct sunlight.

Avoid excessive heat or humidity.

Keep cartons away from water, dust and contamination.

Allow cold-stored rolls to return to normal production-room temperature before use.

If you have specific shelf-life requirements or need technical data about the adhesive and storage conditions, request the relevant TDS / specification sheet before ordering.
