Ziplock Bags with Write-On Panel – Label Them with a Pen

Writable ziplock bags are particularly handy in specific industries and application contexts. Here is an overview of suitable ranges:

• Ziplock bags for spare parts – workshop sorting with screw and split-pin descriptions on the write-on panel
• Ziplock bags for small parts – screws, nuts and washers in industry
• Ziplock bags with Euro hole – with a hanging opening for the retail shelf and POS display

Background knowledge on the closure mechanism, material comparisons and application cases can be found in our detailed guides: zip bags compared (press-seal vs. slider vs. double zip), resealable bags overview (all five main variants explained), PE bag guide (LDPE vs. HDPE material comparison).

Not sure whether the film thickness or size suits your application? We are happy to send free samples before your first order – you can test the ziplock bags with write-on panel in your specific environment before ordering larger quantities.

For individual requirements we offer custom production: bespoke dimensions (outside the standard sizes), an alternative number of write-on strips, individual printing with your logo or special film thicknesses. For food applications with a declaration of conformity to EU 10/2011 → request a custom production.

Ziplock bags with a write-on panel are resealable zip bags with printed white strips for labelling directly. The strips are available as a 1-strip or 3-strip variant and can be written on with all common pens – permanent marker, ballpoint pen, felt-tip pen or pencil. This does away with separate adhesive labels and keeps the labelling firmly attached to the bag.

The zip closure consists of two small profiles that interlock tightly when pressed together. You can open and close the bag as often as you like – typically 500+ cycles without any noticeable loss of seal integrity. Handy for storing food with type and best-before details, workshop sorting with screw descriptions, or pharmacy samples with patient identification.

The material is LDPE (low-density polyethylene) – flexible, tear-resistant, recyclable in the PE stream. Film thicknesses are typically between 60 and 100 microns; for workshop use we recommend at least 90 microns. Food-grade certification to EU 10/2011 is available on request.

Compared with classic bags without a write-on panel, these variants have the decisive advantage of permanent content labelling. Instead of sticking on labels afterwards (which come loose or get dirty), you write the contents, date or patient data directly onto the bag – clearly legible and tamper-proof.

Ziplock bags with a write-on panel are used wherever the contents of a bag need to be clearly identified – without having to rely on separate labels. In the workshop, practice, kitchen and hobby spheres they are one of the most practical sorting solutions there is.

• Workshop sorting of spare parts – label screws, split pins and small mechanical parts with size and type so the right screw is always found quickly.
• Pharmacy and practice documentation – patient samples, tablet portions and dosing packs with patient name and date, hygienic and tamper-proof.
• Kitchen spice storage – spices and baking ingredients with type and best-before details, ideal for a clearly organised pantry.
• Jewellery and collector sorting – gemstones, coins and stamps with type or value labelling in the hobby collection.
• Sample packaging in marketing – product samples with type or batch number for trade fairs and direct marketing campaigns.
• Craft and hobby use – beads, buttons and small materials sorted by colour or size, always labelled and easy to find again.

Thanks to their resealable design, the bags are practical for all applications where contents have to be removed and resealed tightly more than once – without losing the content labelling.

You choose the right variant according to the number of strips, bag size, film thickness and food-grade requirement. Here is an overview of the most important selection criteria:

• Number of write-on strips – 1 strip for simple labelling (type or date), 3 strips for detailed information (type, best-before date, batch).
• Bag size by contents – 40×60 mm for tablets/jewellery, 80×120 mm for screws/small materials, 200×300 mm for spice supplies or larger workshop sorting.
• Film thickness by load – 60–80 microns for light contents (powders, tablets), 90–120 microns for workshop screws, from 150 microns for sharp-edged contents (see extra strong).
• Food-grade certification – for direct contact with food (spices, kitchen supplies) request the EU 10/2011 certified variant.
• Material variant – standard clear LDPE or food-grade for food applications. For sustainable brands, recycled LDPE with a GRS certificate is also available.
• Special sizes and printing – individual dimensions, an alternative number of strips or printing with your company logo as a custom production.

Not sure? We send free samples in advance – this way you can test the right film thickness and size on your specific application before ordering larger quantities.

The decisive advantage of this bag variant is the integrated labelling without separate stickers. Stickers come loose over time, get dirty, leave adhesive residue or can easily be removed by children. The printed write-on strips, by contrast, are firmly attached to the bag and stay legible permanently.

In practice this means: cleaner organisation in the workshop and kitchen, less risk of mix-ups with patient samples in the practice and tamper-proof sample-shipping packaging in marketing. Anyone who has once used the benefits of write-on panel bags is reluctant to go back to working with adhesive labels.

Economically, the bags are convincing thanks to their reusability (500+ opening cycles) and the savings on label costs. With careful handling they last for many years without the write-on strips or the zip closure losing their function. For food applications, conformity to EU 10/2011 is maintained – provided the bags are kept clean.
