Printable Permanent Bag Sealing Tape
Permanent Bag Sealing Tape Printable Release Liner
Product Overview
Printable Permanent Bag Sealing Tape is a double-sided pressure-sensitive sealing tape designed for permanent closure of courier bags, poly mailers, bubble mailers, express bags and other flexible packaging.
Permanent Bag Sealing Tape creates a strong bond between overlapping bag surfaces. Once the release liner is removed and the bag flap is pressed down, the high-tack adhesive creates a secure permanent closure. When the tape, adhesive and bag film are correctly matched, reopening the package may stretch, tear or visibly damage the sealing area, helping provide evidence of unauthorized opening.
Printable Permanent Bag Sealing Tape features release liners that can be customized with your logo, brand name, warning message, opening instructions or other repeating printed designs. It is suitable for packaging manufacturers, custom bag factories and private-label packaging projects.

Product Construction
A typical permanent bag sealing tape consists of several functional layers:
Release Liner – This is the layer that touches the adhesive side of the tape during storage. It protects the adhesive until the bag is ready to be sealed. Options include PEPA, PET, OPP, HDPE or other liner materials depending on the end use.
Hot-Melt Adhesive Side – This adhesive creates a high initial tack to help secure the tape to the bag during bag production.
Carrier Film – The carrier film provides dimensional stability during the coating, rewinding and application process.
Acrylic Adhesive Side – The acrylic adhesive is engineered to provide a permanent bond when the package end user seals the bag.
Finger-Lift Area – An extended liner edge can be provided so users can easily remove the release film before sealing.

Permanent Bag Sealing Tape vs. Resealable Bag Sealing Tape
| Feature | Permanent Bag Sealing Tape | Resealable Bag Sealing Tape |
| Opening Frequency | One-time closure | Multiple opening and closing |
| Adhesion | High permanent tack | Controlled removable/resealable tack |
| Main Purpose | Security and shipment protection | Convenience and repeated access |
| Typical Bags | Courier bags, poly mailers, security bags | Garment bags, retail bags, stationery bags |
| Opening Result | May damage or distort sealing area | Normally opens without damaging bag |
| Typical Buyer | Courier bag and mailer manufacturers | Garment and retail packaging manufacturers |
In most cases, if your customer will need to open and close the bag again, a resealable bag sealing tape should be used.
Suitable Bag Materials
Compatible bag materials include:
PE bags
HDPE bags
LDPE bags
PP bags
BOPP bags
Poly mailers
Bubble mailers
Courier bags
Express bags
Security packaging
Compatible coated paper or kraft mailers
Because PE, PP and other plastic films have different surface energies, adhesion should be tested on the customer's actual bag material before mass production.
For best results, please provide the bag material, film thickness and surface-treatment information when requesting a sample.
Typical Applications
Courier & Express Shipping Bags
Used on courier envelopes and express mailing bags requiring secure one-time closure.
Ecommerce Poly Mailers
Suitable for apparel, accessories, documents and other products shipped through online retail channels.
Bubble Mailers
Provides a convenient peel-and-seal closure for padded mailing envelopes.
Security Bags
Can be used where visible opening or bag damage is preferred after the package has been sealed.
Takeout & Food Delivery Bags
Suitable for selected disposable delivery packaging requiring a strong closure.
Document & Election Mail Bags
Use where repeated opening is not required.
How to Select Printable Permanent Bag Sealing Tape?
For B2B projects, selecting tape by width alone is not enough. Please check the following information before ordering:
1. Bag Material
Tell us whether your bag is PE, HDPE, LDPE, PP, BOPP, kraft paper or another material.
2. Film Thickness
Thin films and thick films react differently when permanent adhesives are applied.
3. Surface Treatment
Surface treatment such as corona treatment can affect adhesion on PE and PP films.
4. Tape Size
Confirm the required liner width and adhesive width according to the bag flap design.
5. Application Method
Please tell us whether the tape will be applied manually or by an automatic bag-making machine.
6. Roll Length
Short rolls are convenient for sampling and smaller production runs, while long rolls or bobbins reduce machine changeover frequency during continuous production.
7. Required Opening Result
If you need the bag to tear or show obvious damage after opening, tell us before sampling so the tape can be matched to the bag film.
Recommended Sample Testing Before Bulk Order
For professional packaging buyers, we recommend testing the tape on the actual production material before placing a large order. The sample test should check:
Initial tack
Bond strength
Liner release
Bag film compatibility
Adhesive transfer
Edge lifting
Sealing consistency
Performance after storage
Performance under transport conditions
Machine feeding and unwinding
Cutting performance
Final opening result
Testing the actual tape + bag film + production process is more meaningful than comparing adhesive specifications alone.
Machine Compatibility
Permanent bag sealing tape can be supplied for different production environments.
When purchasing tape for an automatic bag-making line, please provide:
Machine brand and model
Maximum roll diameter
Core size
Tape width
Unwinding direction
Maximum production speed
Flat roll or bobbin requirement
Tape application position
Cutting temperature if heat cutting is used
Hot-Knife / Heat Cutting
If heat cutting is used on the bag-making machine, please provide the cutting temperature when requesting samples or a quotation. Cutting performance should be checked during sample testing together with the actual tape, bag film and production process.
This information allows us to match the tape construction to your equipment and reduce machine adjustment during production.
Flat Roll vs. Long Roll / Bobbin
Flat Roll
Ideal for:
Sampling
Trial production
Manual operation
Small and medium production runs
Frequent product changeovers
Long Roll / Bobbin
Ideal for:
Continuous production
Automatic bag making lines
Large-volume packaging factories
Reducing roll change frequency
Improving production efficiency
Please specify your equipment requirements when asking for a quotation.
FAQ
Is permanent bag sealing tape the same as resealable tape?
No. Permanent tape is designed for one-time secure closure. Resealable tape is designed to allow the package to be opened and closed multiple times.

Can the liner color be customized?
Yes. Liner color and printed design can be customized according to order requirements.
What bag materials can the tape be used on?
It can be developed for PE, HDPE, LDPE, PP, BOPP and other compatible packaging materials. Because film surface characteristics vary, sample testing is recommended.
