Write-On Panel Grip Seal Bags – 140 Gauge (35 Micron)

Our write-on panel grip seal bags provide a practical way to package, organise and identify products without applying separate adhesive labels. Manufactured from high-clarity 140 gauge (35 micron) LDPE polythene containing 30% recycled material, these resealable bags combine clear product visibility with convenient writable panels.

The white panels provide a visible area for recording important information such as product names, stock codes, batch numbers, quantities, dates, order references and storage instructions. This makes the bags particularly useful in warehouses, workshops, stockrooms, production areas, offices and fulfilment centres where products must be identified quickly and accurately.

Each bag features an integral press-to-close grip seal. The fastening can be secured by pressing firmly along the top of the bag and reopened whenever access is required. No heat sealer, tape, staples or separate fastening materials are needed.

The contents remain visible through the clear sections of the polythene, while the write-on panels make it easy to distinguish between similar products. This combination helps improve organisation, reduce identification errors and make stock handling more efficient.

Available in a comprehensive selection of sizes, our panelled grip seal bags are suitable for everything from jewellery, fixings and electrical components to documents, clothing, accessories and larger commercial products.

Easy-to-Use Write-On Panels

The white write-on panels provide a contrasting surface for recording important product and storage information. Depending on your requirements, the panels can be used to add:

• Product names and descriptions
• Stock codes and SKU numbers
• Batch and lot numbers
• Quantities
• Packing or inspection dates
• Order and customer references
• Storage locations
• Staff initials
• Quality-control information
• Handling instructions

For the clearest result, write on the panel before filling the bag and use a suitable pen, pencil or permanent marker. Allow the writing to dry before handling the bag to reduce the possibility of smudging.

We recommend testing your chosen writing instrument on one bag before labelling a complete batch. The number, size and positioning of the write-on panels may vary depending on the dimensions of the bag.

Secure and Convenient Resealable Packaging

The integrated press-to-close fastening makes these grip seal bags quick and easy to use. Place the product inside and press firmly along the complete width of the seal until the fastening is fully closed.

When access is required, gently pull the two sides apart above the seal. The bag can then be closed again, making it suitable for products that must be inspected, counted, handled or used on multiple occasions.

This resealable design is particularly useful for component storage, order picking, production work, repair kits and stock management. Products remain grouped together, clearly labelled and easy to identify.

How to Measure Write-On Panel Grip Seal Bags

Grip seal bag dimensions are shown as:

Width × Height To Seal

The height measurement represents the usable internal space from the bottom of the bag to the closure. The material above the grip seal is not included in the usable bag length.

For the best fit:

• Measure the widest part of your product
• Measure its full height or length
• Allow additional space for the product’s thickness or depth
• Leave enough room above the contents to close the grip seal
• Consider the space required for writing on the panels
• Select a larger size for bulky or irregularly shaped products

Grip Seal Bags for A5, A4 and A3 Documents

Our write-on panel grip seal bags include practical sizes for storing and protecting standard A5, A4 and A3 paperwork:

• 6 × 9 inch / 150mm × 225mm grip seal bags – suitable for A5 documents measuring 148mm × 210mm
• 9 × 12.75 inch / 225mm × 323mm grip seal bags – suitable for A4 documents measuring 210mm × 297mm
• 13 × 18 inch / 325mm × 450mm grip seal bags – suitable for A3 documents measuring 297mm × 420mm

These resealable document bags are ideal for protecting and identifying paperwork, instruction manuals, catalogues, certificates, photographs, artwork, technical drawings and printed materials.

The write-on panels can be used to add document titles, project numbers, dates, departments, customer references or filing information. The clear areas allow the paperwork to remain visible without opening the bag.

If you are packaging thick document bundles, catalogues, folders or rigid items, measure the complete contents and consider selecting a larger bag to provide sufficient space.

How to Use Write-On Panel Grip Seal Bags

For the best results:

1. Place the empty bag on a smooth, flat surface.
2. Add the required information to the white write-on panels.
3. Allow any ink to dry fully.
4. Insert the product without overfilling the bag.
5. Remove excess air if required.
6. Press firmly along the complete grip seal until it is closed.
7. Check that the fastening is secure before storing or transporting the bag.

Avoid using excessive pressure or sharp writing instruments that could puncture the polythene.

Clear 140 Gauge Polythene Construction

Manufactured from clear 140 gauge polythene, equivalent to approximately 35 microns, these standard-duty panelled grip seal bags are lightweight, flexible and easy to handle.

The material provides dependable everyday protection for lightweight products without the additional bulk or cost of heavier packaging. Clear sections allow the contents, barcodes and enclosed paperwork to remain visible.

For heavy, bulky or sharp-edged products that require greater puncture and tear resistance, a heavyweight grip seal bag may be more appropriate.

Made with 30% Recycled Content

Our write-on panel grip seal bags are manufactured using 30% recycled material, helping reduce the amount of virgin plastic required while maintaining the clarity, flexibility and performance needed for everyday commercial packaging.

The resealable design also allows the bags to be used repeatedly where they remain clean and undamaged, helping businesses make more efficient use of their packaging materials.

Why Choose Our Write-On Panel Grip Seal Bags?

Our panelled grip seal bags combine secure packaging, clear visibility and convenient product identification in one versatile solution. They are an excellent choice for manufacturers, retailers, distributors, warehouses, workshops, offices and eCommerce fulfilment operations.

The integrated panels can reduce the need for separate adhesive labels, while the resealable closure helps make packing, inspection and stock handling faster and more convenient.

These bags are especially useful where similar-looking components must be separated or where products need to be identified using dates, quantities, batch numbers or reference codes.

With a comprehensive selection of dimensions available, it is easy to choose a suitable bag for anything from small components and accessories to larger documents and commercial products.

What Are Write-On Panel Grip Seal Bags Also Known As?

Write-on panel grip seal bags are described using several different names depending on the supplier, industry or application. Customers may also search for them as:

• Panelled grip seal bags
• Grip seal bags with write-on panels
• Write-on gripseal bags
• Write-on self seal bags
• Self-sealing bags with writing panels
• Resealable labelling bags
• Writable plastic bags
• Write-on polythene bags
• Write-on poly bags
• Press seal bags with writable panels
• Clear identification bags
• Resealable stock-control bags
• Component bags with writing panels

Unlike adhesive labels, the write-on panels form part of the bag and cannot become separated from the contents. Unlike permanent adhesive self-seal bags, the grip-seal closure can be opened and resealed repeatedly.

Whether referred to as panelled grip seal bags, write-on self seal bags or resealable labelling bags, they provide a convenient solution for packaging products that must remain both visible and clearly identified.

Important Usage Information

These bags are designed to help protect products from everyday dust, dirt and moisture. They should not be relied upon as completely waterproof, airtight, leakproof or tamper-evident packaging. Avoid packing sharp-edged or excessively heavy products in standard 140 gauge bags, as these may puncture or damage the material. Choose a heavyweight grip seal bag where additional strength is required.

Handwritten information may smudge or fade depending on the writing instrument, storage conditions and handling. Test the chosen pen or marker before labelling a complete batch.

PPWR Compliance Information

Material specifications and supporting product documentation are available for our polythene and polypropylene products to help customers complete their compliance assessments. However, material type, recycled content or food-contact suitability alone does not confirm full PPWR compliance. The responsible economic operator must assess the finished packaging and its intended use against all applicable requirements, including packaging minimisation, substances of concern, recyclability, recycled content, labelling and technical documentation. Customers intending to place these products on the EU market should email sales@expresspackaging.co.uk to request the latest available documentation and confirm suitability for their application before making a PPWR compliance claim.
