Marbig Resealable Polybags 40mm x 50mm Pack of 50

Each bag measures 40 x 50mm, making them suitable for very small items such as screws, beads, seeds, small jewellery pieces, and laboratory samples. They are not intended for larger components - if you need a bigger bag, Marbig offers the same range in several other sizes.

The press-seal closure interlocks along the top of the bag and reseals cleanly when pressed together. The bags are reusable and can be opened and closed multiple times without the seal degrading under normal use conditions.

The 45-micron clear polypropylene material and press-seal closure provide solid protection against dust, light moisture, and incidental spillage. They are not rated for full immersion or prolonged liquid contact, so for waterproof storage you would need a purpose-made waterproof bag.

Each pack contains 50 resealable polybags. This listing is for a single pack of 50.

Yes. The smooth polypropylene surface accepts most permanent markers directly, and standard adhesive labels adhere well to the exterior. This makes them practical for sample identification in laboratory or inventory settings.
