# Gusseted bags 18cm x 4cm gusset x 35cm, 25my

When 20 my feels too light, go for 25 my. Since 2007, we have been the go-to wholesaler for gusseted bags in robust grades such as this 18 x 4 x 35 cm bag. The thicker film is stiffer and more tear-resistant, which suits tools, hardware and goods with sharp edges.

## Gusseted bag 18 x 4 x 35 cm, 25 my

### A sturdier film

Film thickness is the main difference from the 18 and 20 my bags of the same size. A 25 my bag is stiffer, keeps its shape better when standing and resists tearing and puncturing better. It is the grade to choose when contents have corners, points or rough surfaces.

### Typical contents

Think of hardware such as brackets, hinges and fittings, hand tools, hose clamps, boxes of screws, spare parts, sharp-edged plastic parts or sets of kitchen knives in their sleeves. With the 18 cm width these bags also hold bundled profiles and larger sets.

### Using it well

Fill the bag with the heaviest side down, fold over the top and close it with tape, a clip or a heat sealer. The bag is open and not resealable. The stiffer film makes the fold stand more firmly, which gives a neat result with a heat sealer.

The film is transparent and suitable for direct food contact, so the same bag can also hold bread, vegetables or dry goods. LDPE is a recyclable plastic. If the contents are light and smooth, the same size in 18 or 20 my is the more economical choice.

## Frequently asked questions

### Why choose 25 my over 20 my?

25 my is stiffer and more resistant to tearing and puncturing. It is a better choice for hard, angular or sharp contents, and it keeps its shape better when the bag is standing.

### Can I use the bag for tools?

Yes, tools and hardware are typical contents. Test a sample with your sharpest or most angular item to be sure the thickness is right for your goods before ordering a full box.

### Does the thicker film affect sealing?

A heat sealer may need a slightly longer sealing time for thicker film. Test and adjust your sealer on a few bags, or use tape or a clip if you pack by hand.

### Is 25 my food-safe?

Yes. The LDPE is suitable for direct food contact in every thickness. The thicker grade is simply stiffer and more resistant, which can be handy for heavier food items.
