Resealable Bag Sealing Tape RFQ Information Checklist
Resealable Bag Sealing Tape RFQ Information Checklist
Resealable bag sealing tape is a double-sided Adhesive Tape for sealing plastic bags. HDPE, OPP, PE and aluminum film are named film-material options. Right- and left-side glue orientations are available. For a bag converter or packaging buyer, those are not minor details: they define the tape's relationship to the bag construction and the converting process.
The stated film-width options are 9 mm, 12.5 mm, 17 mm, 18 mm, 20 mm and 25 mm, or customized. The stated roll length is 500 m or customized. A useful quotation request should therefore name the actual bag, closure layout, orientation, width and roll requirement rather than ask for a generic price for “resealable tape.”
Start With the Bag, Not the Tape Roll
The tape needs to be selected around the bag it will help close. Before drafting an RFQ, collect the information that exists on the converter's drawing, bill of materials or current production sample.
| Bag input | What to provide | Why it matters |
|---|---|---|
| Film construction | The bag film material and relevant layers | The proposed tape configuration must be discussed against the actual film. |
| Bag format | Bag width, length, opening location and closure position | The supplier can understand how the closure is positioned. |
| Conversion process | Manual, semi-automatic or line-based steps used by the buyer | The sample plan can reflect the real interface. |
| Orientation | Required right- or left-side glue orientation | Orientation must match the bag design and process direction. |
| Commercial scope | Sample quantity, expected order quantity, destination and timing | The RFQ can be scoped to the buyer's purchasing need. |
This preparation avoids a common sourcing problem: comparing offers that use different assumptions about film, side orientation or roll format. When those inputs are stated in the first message, the buyer can compare answers on the same basis.
Confirm the Closure Orientation
Right- and left-side glue orientations are available. The correct choice depends on how the bag is designed, presented to the converting process and opened or closed in the buyer's workflow. Do not leave this field as “standard” unless the buyer's team has checked the current bag sample and process drawing.
Use a simple orientation check before requesting samples:
1. Place a marked sample bag in the same direction used on the line or at the workbench. 2. Mark the intended closure location and which side must carry the functional adhesive relationship. 3. Record whether the bag is viewed from the front, back, opening side or machine feed direction. 4. Include a sketch or photograph of the marked bag in the RFQ when possible. 5. Ask for the proposed orientation to be identified clearly on the sample record.
The point is not to make a process promise from a drawing. It is to ensure that a sample is sent for the correct side and bag layout. A small orientation error can make a technically plausible quote impossible to assess on the buyer's equipment.
Specify Film Material, Width and Roll Format
The named film-material options give the buyer a starting point: HDPE, OPP, PE and aluminum film. State which material is present in the current bag and identify any layers or treatment that may affect the converting discussion. If the bag uses another material or a multi-layer construction, present it as a changed condition and ask for a configuration-specific evaluation.
For width and roll format, build the RFQ from the machine or process needs rather than a guess:
- specify the required film width or the closest listed starting option;
- state the target closure position and any dimensional tolerance used by the buyer;
- identify the preferred 500 m roll length or explain the required alternative;
- add core, winding, packaging and handling requirements if the buyer's equipment depends on them;
- state whether the project needs a standard sample, a pilot sample or a production-oriented discussion.
CONPAIN invites discussion of customized resealable bag sealing tape specifications. That invitation is most useful when the buyer supplies the actual bag film, orientation, width, roll format, process condition, quantity and destination. It is a route to discuss options, not a substitute for confirming a specific line or performance requirement.
Plan a Process-Representative Sample
The sample should be applied to the bag and reviewed through the buyer's intended converting or packaging sequence. Create a brief record that can be shared with procurement and technical teams:
| Sample record | Information to capture |
|---|---|
| Tape identification | Proposed film material, orientation, width and roll reference |
| Bag identification | Material, dimensions, closure layout and relevant drawing reference |
| Application process | Equipment or manual sequence used, with the direction of travel |
| Inspection points | Alignment, handling observations, closure position and buyer-defined checks |
| Next decision | Accept for further evaluation, request a changed configuration or stop the trial |
Any requirement for repeated opening, special surface behavior, antistatic properties, printing or a particular line speed should be defined as a project-specific test question. Do not infer that outcome from a general product description. Put the needed condition in the RFQ and request the relevant sample or documentation.
RFQ Checklist
Use this checklist when contacting CONPAIN about resealable bag sealing tape:
- bag use, dimensions and closure location;
- bag film construction and any relevant layer information;
- required right- or left-side glue orientation;
- target film width and roll format, including whether 500 m is suitable;
- converting process, line or workbench interface and direction of travel;
- preferred sample configuration and buyer-defined acceptance checks;
- printing, color, packaging or documentation requirements if applicable;
- expected order quantity, destination and requested delivery window.
If the listed options do not fit the bag or process, request a customized-specification or tailored-option discussion. Include the changed film, desired width, orientation, roll interface and sample objective so the next conversation stays tied to a real converting need.
Frequently Asked Questions
What is resealable bag sealing tape?
It is a double-sided adhesive tape for sealing plastic bags. The selection should be made around the bag construction and converting interface.
Which film materials can be specified?
HDPE, OPP, PE and aluminum film are named film-material options. Confirm the exact proposed material against the buyer's bag film.
Why does glue-side orientation matter?
Right- and left-side glue orientations are available. The correct choice must match the bag layout and process direction, so it should be explicit in the RFQ and sample record.
Which widths and roll length should be stated?
The listed widths are 9 mm, 12.5 mm, 17 mm, 18 mm, 20 mm and 25 mm, or customized, and the listed roll length is 500 m or customized. Confirm the required interface before ordering.
What should a converter include in an RFQ?
Include the bag film, bag dimensions, closure position, orientation, target width, roll format, process details, sample criteria, quantity and destination.
