Ziplock bags – also called resealable or press seal bags – open and reclose airtight as often as you like. The zip closure is formed by two profiles that interlock when pressed together. Ideal for storing food, sorting small parts, posting jewellery, pharmacy samples and much more.

Available transparent for visible contents, food-grade to EU 10/2011, extra strong for sharp-edged contents, with a write-on panel for labelling, or as a mini format and XL. For a slider closure, see slider bags.

Made from LDPE in standard thicknesses of 60–120 µm. For workshop use we recommend at least 90 µm. Custom printing available on request.

What are ziplock bags?

Ziplock bags are flexible packaging bags with an integrated zip closure made of two profiles that interlock tightly when pressed together. The closure opens and recloses as often as needed – no tools, no adhesive, no wear.

The standard material is LDPE (low-density polyethylene) – flexible, tear-resistant and recyclable. Food-grade versions are additionally certified to EU 10/2011.

Ziplock bags are also known as resealable bags, press seal bags or grip seal bags – all referring to the same product with similar properties.

What are ziplock bags suitable for?

  • Small parts: screws, nuts, fuses, jewellery, sorted goods
  • Food: spices, dried fruit, tea (food-grade variant)
  • Travel: cosmetics, tablets, liquids for hand luggage
  • Industry: spare-part shipping, sample bags, material storage
  • Workshop: sorting repair parts, drill bits, hex nuts
  • E-commerce: shipping small parts, sample bags to enclose
  • Pharmacies & medical: tablets, pills, sterile packaging
  • Private use: jewellery storage, travel toiletries, craft materials

  • Transparent for visibility, or with a write-on panel for identification.
  • Tear-resistant: reliably sturdy even in thinner wall thicknesses.
  • Printable with your logo, branding or mandatory labelling.
  • Private & commercial: all customers — B2B and B2C alike — receive volume pricing directly in the order table.
  • Recyclable: LDPE can be recycled as a single material; available in recycled material on request.
  • Fast shipping from our German warehouse.

Material properties of ziplock bags in detail

Ziplock bags (colloquially also press seal bags or Minigrip) are made from LDPE film with an integrated ziplock closure. The material thickness determines tear resistance, light protection and the stability of the resealable closure.

LDPE 50 microns — standard transparent variant

Crystal-clear polyethylene film for light contents: small parts, spare parts, jewellery, screws, samples. Stable up to approx. 200 g fill weight. Tear-resistant, flexible, cost-effective. Ziplock closure with a double lip for a secure seal across repeated openings.

LDPE 90 microns — extra-strong for commercial use

Reinforced film thickness for heavy or sharp-edged contents: metal parts, tool spare parts, industrial products. Higher puncture resistance and longer service life with repeated reuse. Suitable for warehouse packing and shipping.

LDPE with write-on panel

Variant with a matt strip at the top right on the front of the bag — can be written on with a ballpoint pen, pencil or marker. Practical for workshops, laboratories, pharmacies and shipping with individual content labelling without a separate label.

LDPE with Euro hole

Reinforced punched hole at the head of the bag for display on slat walls in retail. Compliant with the standard 4 mm Euro hole norm.

Food-grade variant

LDPE film certified for direct food contact in accordance with EU Regulation 10/2011. Declaration of conformity available on request. Suitable for dry foods, spice samples and herb blends.

Ziplock mechanism: double-lip system for a secure seal, opened manually with thumb pressure or by machine.

Custom options — bespoke sizes and printing

Ziplock bags can be produced with brand printing and in bespoke sizes.

Printing process

Printing using the flexographic process with up to 4 colours, including simple Pantone colours. The printable area is below the ziplock closure; the closure zone remains unprinted.

Bespoke sizes

Freely selectable bag formats in width (40–300 mm) and height (50–400 mm). Material thickness optionally 50, 60, 70, 90 or 100 microns. Optionally with a Euro hole, hanging tab or write-on panel.

Sustainability and recyclability

Ziplock bags made from pure LDPE are mono-material and therefore recyclable. The ziplock closure is made from the same polyethylene as the film and does not interfere with recycling.

Mono-material recycling

In the German sorting system, pure LDPE bags are identified via NIR detection and fed into the PE recycling stream. Dispose of them via the yellow recycling bag. Ideally remove food or dirt residues before disposal.

Reusability

The ziplock closure allows repeated opening and closing without loss of function. In the home and workshop, one ziplock bag often replaces 5–10 single-use film bags — material efficiency through reuse.

PPWR compliance from 2030

LDPE bags already meet the EU Packaging Regulation today, as they are fully recyclable as a mono-material. For sustainability-focused brands we additionally recommend the use of recyclable printing inks in line with the RecyClass design guideline.

Recycled-content variant (in preparation)

On request we can assess processing with post-consumer recyclate (PCR content up to 30%), depending on the required food contact. For commercial applications without food contact, a higher PCR content is possible.

Frequently asked questions about ziplock bags

What is a ziplock bag?

A bag with an integrated zip-profile closure that seals tightly when pressed together and can be opened as often as you like. Synonyms: resealable bags, press seal bags, ziplock pouches, Minigrip bags.

Press seal or slider closure – which is better?

Press seal: cheaper, tighter, the standard. Slider closure: more convenient, faster to open and close. Detailed comparison in the ziplock bag guide.

Are ziplock bags food-grade?

Only the explicitly certified variants meet EU 10/2011 → food-grade variant. Declaration of conformity available on request.

How often can I open a ziplock closure?

High-quality ziplock closures withstand 500+ opening cycles. The tightness gradually decreases but remains usable for a long time.

Which wall thickness for screws / sharp-edged contents?

At least 90–120 microns. For particularly sharp-edged contents (sheet metal, split pins), choose extra-strong bags from 150 microns.

Which sizes are available?

From mini (40×60 mm) to large format (400×600 mm). Detailed overview in small ziplock bags and large ziplock bags.

Write-on panel for labelling?
