# Gusseted bags 18cm x 4cm gusset x 50cm, 20my The all-rounder among long gusseted bags: 18 x 4 x 50 cm in 20 my. Since 2007, we have been the go-to wholesaler for gusseted bags for long loaves, large bouquets and bulky bundles, and this is the size and thickness to start with. The film is transparent and food-safe. ## Gusseted bag 18 x 4 x 50 cm, 20 my ### The default for long and wide If your product is both long and fairly wide, this is where to start. The 18 cm width and 50 cm length take long loaves, large bouquets, curtain panels, bundles of leaflets, yoga mats, rolled textiles and collections of tools. The 20 my film strikes a balance between flexibility and strength. ### Bakery and florist Bakers use it for long loaves and stacks of rolls, florists for generous bunches. The clear film shows the contents, and the 4 cm gusset prevents the bag from collapsing against the product. The film is suitable for direct food contact. ### Choosing your thickness The same dimensions exist in 18 and 25 my. Use 18 my for light and soft goods, 20 my for general use, and 25 my when the contents are sharper or rougher. Thicker film is stiffer and more resistant to tearing and puncturing. Close the open bag with tape, a clip or a heat sealer; it is not resealable. Used bags can be recycled as LDPE, together with other clean plastic film. ## Specifications FeatureSpecificationTypeGusseted bag (side-gusset bag) MaterialLDPE (low-density polyethylene) ColourTransparent Thickness20 my (microns) Width18 cm Side gusset4 cm Length50 cm FinishStandard Food contactSuitable for direct food contact ClosureOpen bag, not resealable Packaging1000 pieces per box Browsing other bag types?

Switch to 18 my for light goods or to 25 my for sharper and rougher ones. Testing a sample with your own product settles the question. ### Will a yoga mat fit? A rolled mat might, depending on its diameter; the opening is 18 x 4 cm. Check the diameter of the rolled product and compare it with the bag before ordering a full box. ### How do I close a 50 cm bag neatly? Fold the top over a few times and use tape or a clip, or seal it with a heat sealer. A longer fold-over gives a firmer closure and keeps dust out of the bag. ### Are these bags recyclable? Yes, LDPE is a recyclable plastic. Offer clean bags with other plastic film, according to the collection rules where you are, and remove tape or labels if you can.
