Extra strong ziplock bags have a film thickness of 90 to 100 microns – almost twice as strong as the 50-micron standard. This increased material thickness gives the bags crucial robustness for applications where standard stock fails: heavy contents from 500 g, sharp-edged screws or metal parts, rough storage and shipping conditions or frequent reuse in everyday workshop life.

Besides the film thickness, the zip closure itself is built to be more robust. While standard zips can wear out after 100–300 closing cycles, extra strong closures withstand several hundred to a thousand cycles. That makes them ideal for reusable applications: workshop bags from which components are removed again and again over weeks or months; storage bags for screw or small-hardware assortments; food storage bags that are opened frequently.

The LDPE film remains transparent and food-grade (in accordance with EU 10/2011), so extra strong bags are suitable for all areas of use – from industrial shipping packaging to kitchen storage of heavy foods such as hard cheese, frozen meat or pre-portioned dried fruit. They are available in the common standard formats from 80×120 mm to 300×400 mm.

• Shipping heavy small parts: screw assortments, spare parts, workshop consignments
• Workshop storage with frequent opening: daily service use, hard-wearing reusable bags
• Sharp-edged components: metal strips, etched sheets, springs, blade spare parts
• Heavy foods: hard cheese, frozen meat, pre-portioned dried fruit
• Industrial granulates: threaded goods, pellets, plastic granulate in 1–5 kg quantities
• Outdoor and travel use: waterproof packaging of sensitive devices or documents

• 90 microns: standard extra strong, considerably more hard-wearing than 50 microns, cost-effective
• 100 microns: premium robustness for extreme loads or reuse
• Sizes: from 80×120 mm (small shipping sets) to 300×400 mm (bulk packs)
• With or without write-on panel: a write-on panel makes storage and shipping handling easier
• Transparent: all extra strong bags are clear – contents recognisable at once
• With Euro hole: for hanging display in retail or on a storage pegboard
• Food-grade: EU 10/2011-compliant for food contact
• Combined with vacuum sealing: extra strong films are partly vacuum-suitable

We have imported ziplock bags since 1976 and know the quality differences in detail: a 90-micron film is not automatically a good 90-micron film – the impact strength, puncture resistance and closure quality vary considerably between suppliers. Our suppliers meet the strict requirements for consistently high material quality, so you can rely on reproducible performance.

In shipping applications in particular, material quality is a direct cost factor: every torn bag in shipping means the cost of a complaint, reputational damage and re-dispatch. With extra strong bags you significantly reduce the risk of damage – at a small surcharge over standard stock. Our packaging specialists help you find the right film thickness for your weight-to-volume ratio.

Dispatch is from our German warehouse. Extra strong standard sizes are usually available immediately. All customers – B2B and B2C alike – receive volume pricing for bulk-pack quantities. Free samples are available on request – so you can run a stress test with your real application before placing a main order.
