# Freezer bags 11 x 4.5 side gusset x 30 cm. 70 microns - Transparent ## Extra-strong 70 micron freezer bags for bone-in products Small bones, shells and sharp edges easily puncture a thin bag. That is why this 11 x 4.5 x 30 cm freezer bag is made from extra-thick 70 micron LDPE. Since 2007, we have been the go-to wholesaler for freezer bags in both standard and heavy-duty grades. ### For chicken legs, prawns and game portions Think bone-in chicken thighs, portioned spare ribs, shell-on prawns or game. The thicker film absorbs the pressure from sharp parts, so the bag stays intact during stacking, transport and removal from the freezer. ### Longer storage life in the cold store A thick film lets less air and moisture through, helping to prevent freezer burn on products stored for months. Close the bag with a [cable tie](https://www.kortpack.nl/en/closure-materials/cable-ties) to keep it airtight. For lighter products, the same size is also available in a 50 micron version. ### Specifications Width11 cmGusset (per side)4.5 cmLength30 cmThickness70 micronMaterialLDPEColourclearPacked1000 bags per boxDo you have questions about which size of [plastic bags](https://www.kortpack.nl/en/wrapping-film-shrink-film-top-sheets-pallets/plastic-bags) is best suited to your situation?

This makes the bag more resistant to punctures from bones or shells and protects the contents from drying out for longer. ### Is this bag suitable for shellfish and crustaceans? Yes, the thick film is ideal for shell-on prawns, mussels and other products with hard, sharp edges. ### Is the thicker film harder to close? No, 70 micron LDPE stays supple. Simply twist the neck and close it with a cable tie or heat-seal it. ## Gerelateerde producten - [Transparent stretch film 20my x 50cm x 300m - 6 rolls](en/palletdeals/transparent-stretch-film-20my-x-50-cm-x-300m) --- Published: 2026-10-20 14:12:00 Source: https://www.kortpack.nl
