Shipping Bag Sealing Tape is intended for use by manufacturers of courier bags, shipping bags, poly mailers, shipping envelopes and other flexible shipping bags where the closure must be factored into the bag production process.

Performance for shipping bag manufacturers includes more than the ability of the tape to create adhesive bonds. The sealing tape must function properly with the entire packaging design.

This includes:

The bag film

Flap design

Sealing location

Liner handling

Handling of the final package after filling

Zhuolv offers shipping bag sealing tape for manufacturers that require repeatable sealing performance during high volume flexible packaging production runs.

Shipping bag sealing tape is designed to allow manufacturers to:

Achieve repeatable closure during bag production

Create consistent sealing results batch-to-batch

Enable smooth liner handling during sealing

Ensure a clean finished bag appearance

Achieve reliable handling of filled shipping bags

Choosing the correct sealing tape for shipping bags will depend on the production method and desired characteristics of the finished shipping package.

Closure Performance Considerations for Shipping Bags

Shipping bag manufacturers need to focus on more than adhesive bonds when selecting a tape.

Closure stability from package production to shipment handling is critical for shipping success.

There are three key areas to focus on when evaluating Shipping Bag Sealing Tape.

---

1. Closure During Bag Conversion

Shipping bag conversion is the process of turning flat bag materials into finished shipping bags.

During this process the sealing tape is integrated into the bag manufacturing process.

Factors to consider include:

Placement of the tape during bag formation

Sealing location accuracy

Liner tear away mechanics

Compatibility with bag production methods

Shipping Bag Sealing Tape should allow the manufacturer to reproduce the same closure quality during every production run.

---

2. Closure Reliability After Bag Fill

Conditions often change after shipping bags are filled with products.

After filling, the seal location can be subject to:

Flap movement

Package expansion

Handling during shipment preparation

For this reason, closures should be evaluated on a filled shipping bag instead of only on a blank film sample.

---

3. Finished Shipping Bag Appearance and Handling

Courier bags and e-commerce shipping packages are often judged on appearance by the end customer.

Factors that are often considered include:

Clean sealing lines

Uniform flap closure

Box-like shape after handling

Shipping Bag Sealing Tape should allow manufacturers to maintain a consistent package quality from production to delivery.

---

Shipping Bag Sealing Tape versus Other Types of Bag Sealing Tape

Each available sealing tape product is optimized for different packaging applications.

The following matrix is provided to help buyers select the right tape for their production.

Buyer Need	Tape Recommendation
Standard production of courier bags and shipping envelopes	Shipping Bag Sealing Tape
Single use closures where reopening is not expected	Permanent Bag Sealing Tape
Applications where openings and closings will occur multiple times	Resealable Bag Sealing Tape
Where printing is required on the same tape	Printing Bag Sealing Tape

Shipping Bag Sealing Tape is differentiated by its use in shipping packaging production.

Buyers that choose Shipping Bag Sealing Tape are typically doing so for a reliable production sealing solution, not a tape that will be repeatedly opened by consumers.

Shipping Bag Seal Tape Applications and Considerations

Courier Bags Manufacturers

Couriers bag manufacturers will usually need sealing tape that can perform reliably during high volume production.

Factors to consider include:

Ability to consistently achieve flap closure

Ease of use during the production process

Ability to achieve the same finished bag quality every time

Sealing tape should be conducive to the manufacturers production process rather than create unnecessary process adjustments.

---

Poly Mailer Manufacturers

Poly mailers used for e-commerce shipping packages should have both reliable closure and a clean appearance.

Factors to consider include:

Ability to work with flexible mailer designs

Achieve consistent sealing after package fill

Allow for easy opening by customers

The chosen sealing tape should work with how the poly mailers will be used.

---

Express Envelope Manufacturers

Express envelopes may need lightweight sealing solutions that can be easily integrated into production.

Focus on:

Closure reliability

Production speed

Finished package quality

---

Selecting the Right Shipping Bag Sealing Tape

Choose a Shipping Bag Sealing Tape that works with the entire shipping bag design.

---

Bag Design

Share information about:

Bag film

Bag construction

Flap design

Sealing location

---

Production Process

Confirm:

Application method

Production speed

Liner tear away method

Exact tape placement

---

Final Conditions

Define:

Expected handling of the final package

Transportation conditions

Desired opening experience

The goal should not be to find the strongest tape.

Rather, manufacturers should seek a tape solution that works with their entire shipping bag design.

---

Sample Approval for Shipping Bags

Before placing bulk orders, it is highly recommended that sealing tape be approved using the actual bag design and production conditions.

Conditions to consider include:

Evaluation Criteria	Purpose
Bag film chosen	Verify sealing performance on actual bag material to be used
Flap seal result	Check consistency and accuracy of flap seal after bag formation
Liner tear away mechanics	Verify manufacturing compatibility with liner handling method
Filled package handling	Ensure seal quality after filling

Sample approval should be based on performance of the final shipping bag rather than tape properties.

---

Shipping Bag Sealing Tape Quality Points

Important quality aspects of Shipping Bag Sealing Tape include:

Consistent core build

Stable adhesive

Reliable liner release characteristics

Uniform roll production

These are just a few of the characteristics that allow us to ensure consistent performance for customers producing shipping bags at scale.
