BOPP Resealable Bag Sealing Tape for PE Bags

12/5/7mm × 1540m | Double-Sided Acrylic Adhesive | Resealable Closure Tape for PE Plastic Bags

Our BOPP resealable bag sealing tape is designed for manufacturers of PE self-sealing plastic bags. It uses a double-sided pressure-sensitive acrylic adhesive system that bonds securely to the bag while allowing the finished bag to be opened and resealed multiple times.

The 12/5/7mm × 1540m specification is suitable for garment bags, stationery bags, gift packaging, retail bags and other reusable PE packaging.

Unlike permanent bag sealing tape, this resealable version is intended for packaging that needs repeated opening and closing without destroying the bag.

Product Specifications

What Does 12/5/7mm Mean?

12 mm refers to the release-film width, while 5 mm and 7 mm refer to the two adhesive-track widths. The wider liner leaves an easy-to-grip finger-lift area, making the protective film easier to remove.

Tape Construction

Resealable bag sealing tape is not an ordinary double-sided tape. Its layered construction is designed specifically for plastic bag manufacturing.

Typical construction:

BOPP Release Liner

Resealable Acrylic Adhesive

PET Carrier Film

Permanent Acrylic Adhesive

PE Bag Film

One adhesive side bonds the tape firmly to the plastic bag during bag production. The other side creates the resealable closure used by the final customer.

The extended BOPP liner provides a finger-lift edge so users can easily peel away the release film before closing the bag.

Resealable Tape vs. Permanent Bag Sealing Tape

If your application is for courier bags, security bags or one-time shipping envelopes, ask us about Permanent Bag Sealing Tape instead.

How to Choose the Correct Tape

Tell Us Your Bag Material - Confirm whether your bag is PE / LDPE / HDPE / CPE / PP / OPP / CPP or another plastic film. Different films and surface treatments can produce different adhesive results.

Tell Us the Bag Film Thickness - For example: 30 μm / 40 μm / 50 μm / 60 μm / 80 μm. Bag thickness, additives and surface treatment can affect adhesion, so sample testing is recommended before mass production.

Select the Tape Width - The standard reference specification for this product is 12/5/7mm. Other widths can be discussed for OEM production depending on your bag design and production requirements.

Confirm Adhesive Direction - Please specify Left / Right / Center. The correct glue position depends on the installation direction of your bag-making machine.

Confirm Roll Length - The standard specification is 1540 m/roll. For continuous production or special equipment, tell us your required roll format when requesting a quotation.

Confirm Printing - Options may include Blank liner / Colored line / Logo printing / Customized text. Please send artwork if custom printing is required.

Suitable for Automatic Bag Production

This sealing tape can be integrated into plastic bag converting and bag-making processes.

For machine applications, please provide:

Machine type

Maximum roll diameter

Tape feeding direction

Production speed

Required glue position

This information helps us recommend the correct roll format and tape orientation before shipment.

Quality Control for B2B Orders

For bulk orders, the most important factor is not simply whether the tape feels sticky by hand. Tape performance should be checked on the actual plastic film.

We recommend confirming:

Adhesive position - consistent throughout the roll

Tape width - within agreed tolerance

Roll length - according to specification

Liner release - smooth and easy to peel

Bag adhesion - stable bonding to the target film

Resealing performance - suitable for the intended packaging

Roll winding - flat and suitable for machine feeding

Printing position - consistent for customized orders

For new bag materials, we recommend sample testing before placing a large production order.

Storage Recommendations

Keep unused rolls in the original packaging and store them in a clean, cool and dry environment.

Avoid direct sunlight, excessive heat, high humidity, dust and contamination of the adhesive surface.

For long-term inventory or applications with special temperature requirements, please request the applicable product specification before ordering.

Important Material Compatibility Note

Adhesion performance depends on more than the tape itself. PE film formulation, recycled-content level, slip additives, corona treatment, film thickness and surface contamination may all affect bonding performance.

For this reason, we strongly recommend testing the sealing tape on your actual production film before mass production. A tape that performs well on one PE film may behave differently on another PE formulation.

FAQ

1. Is this BOPP resealable bag sealing tape suitable for PE bags?

Yes. This product is designed for PE plastic bag applications. Because PE formulations vary, testing on the customer's actual film is recommended before bulk production.

2. Why is a BOPP release liner used for PE bag applications?

The BOPP release film provides good dimensional stability and works well in PE bag production and converting processes. Tape selection should still be confirmed against the actual bag film.

3. What does 12/5/7mm mean?

It refers to the liner width and the two adhesive-track widths: 12 mm liner / 5 mm A-side adhesive / 7 mm B-side adhesive.

4. What is the standard roll length for this product?

The standard specification referenced for this BOPP resealable bag sealing tape is 1540 meters per roll.

5. Can the adhesive position be left, right or center?

Yes. Left, right and center adhesive positions can be produced according to the bag structure and machine feeding direction.

6. Can this tape be used on an automatic bag-making machine?

Yes. Please provide the machine type, maximum roll diameter, tape feeding direction, production speed and required glue position so the roll format and tape orientation can be matched to your line.

7. Can I customize the width, roll length or liner printing?

Custom tape width, adhesive width, roll length, liner color, printed lines, logo printing and other OEM options can be discussed according to your bag design and order requirements.

8. Should I test the tape on my PE film before placing a bulk order?

Yes. Film formulation, recycled content, slip additives, corona treatment, thickness and surface condition can affect bonding. Testing on the actual production film is strongly recommended.

9. Is this the same as permanent bag sealing tape?

No. This version is designed for resealable packaging. If you require a one-time tamper-evident closure for courier or security bags, permanent bag sealing tape is the more suitable option.

10. Is this tape automatically suitable for direct food contact?

No. Do not assume direct-food-contact compliance simply because the tape is used on a food packaging bag. If FDA, EU food-contact or another specific compliance standard is required, confirm the target market and regulation before ordering so the applicable product and documentation can be checked.
