Description
Sample bags with zip closure measuring 70 mm wide by 100 mm long are reclosable PE pouches intended for routine laboratory sample handling and short-term storage. They are produced from low-density polyethylene (LDPE) with a 50 µm film thickness, giving a flexible, transparent bag that shows contents at a glance. The zip closure allows multiple open–close cycles without ties or heat sealing, which is useful during preparation, weighing, labelling and internal transfer of dry or solid materials. Supplied as 10×100 pieces (1000 bags), the pack size matches high-consumption environments such as central sample reception, QC laboratories and teaching facilities. The 70 × 100 mm dimensions accommodate a wider range of specimen volumes than smaller minigrip bags while remaining easy to store in trays and cabinets. These bags from manufacturer Labbox fit standard workflows where simple LDPE containment and reliable resealing are sufficient. Consistent film gauge and a practical bulk format help laboratories maintain a steady supply of disposable sample pouches.

Questions about Zip-lock bags, 70x100 mm, polyethylene, 10x100 pcs
What is this article?
Zip-lock bags, 70x100 mm, polyethylene, 10x100 pcs is the article on this page. Luminix Health distributes Labbox for laboratory use. It sits in Screw caps & closures, inside Stoppers, caps & closures, in Matériel de laboratoire.
A screw cap has a thread and a liner. The thread has to match the bottle. The liner has to survive the liquid: a pulp liner fails in a solvent that a PTFE-faced liner ignores. The colour of the cap is not the specification.
A closure is the part that decides whether a bottle stays shut and whether the contents attack the seal. A ground-glass stopper matches a ground neck. A screw cap needs the right thread and a liner that survives the liquid. Rubber and silicone stoppers push into a mouth. The liner, not the colour of the cap, is the chemical choice. The vessels they close are indexed under ISO laboratory glassware.
