LDPE ziplock bags without labeling strips 50 microns

The LDPE ziplock bags without write-on panels 50 microns are crystal-clear bags made of soft polyethylene with a double-lip press-to-close zip. The 50-micron film is the standard wall thickness for light to medium contents that you want to open again and again and reseal securely.

What the 50-micron ziplock bags are used for

This wall thickness is the all-rounder for packing and storing. Because the bag stays fully transparent, you recognise the contents without opening — practical in warehouse and workshop logistics. Typical uses are:

• Food portions: spices, dry products, powders, herbs
• Small and spare parts: screws, seals, electronic components
• Samples, specimens and set compositions for shipping

Material and food suitability

LDPE (low density polyethylene) is soft, tear-resistant and crystal-clear. The material is cold-resistant down to around -40 °C, so suitable for freezing, and stays dimensionally stable up to around 70–80 °C. The bag is food-grade per EC 1935/2004 and EU 10/2011 — we send you the declaration of conformity on request. As a pure mono-material it runs cleanly in the PE recycling stream and is thus PPWR-compliant from 2030.

50 microns or 90 microns — choosing the right thickness

At 50 microns you are well served for standard contents without extreme stress: light, transparent, cost-effective per bag. If you have sharp-edged, heavy or pointed contents that could puncture — such as metal parts with burrs — reach for the stronger 90-micron variant. If you need a writing surface to note batch and date, the version with three white write-on panels is the better choice.

Closure and reuse in everyday use

The double-lip press-to-close zip works on the press-to-close principle: you run the two profile lips together with your fingers until they audibly engage — without a slider or tool. Over 30 to 50 opening and closing cycles, the closure stays functionally reliable, so you can reuse the same bag multiple times instead of discarding it after a single use. This not only saves material but keeps powders, small parts or food residues protected from dust and moisture between removals. Because the film is a pure PE mono-material, the bag belongs in the recycling bin at the end of its life cycle and is cleanly recovered in the German recycling stream.
