You are viewing this rangeFrom individual components to complete kits.
Select a bag around the contents' size and shape, and how they will be handled next.
Parts and accessories
Screws, connectors, small components and assembly parts. Clear film allows the contents to be identified without opening the bag.
Kits and instructions
Keep assembly components, accessories and accompanying documents together. The bag helps the kit stay complete.
Retail and warehousing
Organise stock, store spare parts and prepare products for further packing. Select a format that suits your storage system.
The right format makes packing easier.
Measure the contents, including thickness and irregular shapes. A flat item and a bulky kit of the same length may need different bags. Allow room to insert the product and fully close the zipper.
Check how dimensions and pack quantities are stated on the product card. For repeat packing, compare the selected format with your current bag. When changing ranges, compare the specification too.
How to choose zipper bags: read the guide →Three details to get started.
- Range and dimensions. Specify STRONG and the size in millimetres, or send the product link.
- Quantity and application. State the number of bags or packs and describe what you will pack.
- Destination and frequency. Include the delivery location and whether you need a one-off or recurring order.

Read the guide →STRONG zipper bags: customer questions
How do SMART and STRONG differ?+
SMART has a red line above the closure and is our core range for everyday packing. STRONG has no red line and carries an LDPE marking on the lip above the closure. Compare specifications on individual product cards.
How should I specify the size?+
Give the dimensions in millimetres and a product link. Describe the contents, particularly bulky or irregular items. Item length alone is not enough to choose a bag.
Can the bag be resealed?+
The zipper allows opening and reclosing. Keep the closure clear of contents and check that it is pressed shut along its full width.
Ile pieces zawiera opakowanie?+
Check packaging on the selected size's product card. Distinguish individual bags, inner packs and outer cartons in your enquiry so the quote matches your requirement.
Do Q40 and Q50 always state an exact thickness in microns?+
Q40 and Q50 are catalogue range designations associated with the batch's average film thickness. Do not treat the name alone as a guarantee of one fixed µm value; check the exact product specification.
Can I buy for resale?+
Yes. Protectmedical's business range also serves wholesalers and distributors. Tell us the ranges, sizes, quantities and customers you serve to discuss a trade partnership.
