PE Zip-Lock Bags

The highest-volume packaging consumable we source. PE zip-lock bags are used for food packing, hardware, jewellery and general retail, and the specification that actually matters is not the bag — it is the thickness, the closure quality and whether the material is food-contact grade. Two bags that look identical in a photo can differ by 40% in film weight.

Questions buyers ask

Straight answers on PE Zip-Lock Bags

How do I compare quotes on zip-lock bags?

Compare on the same size, the same film thickness and the same material grade — then on pieces per carton and carton dimensions. A cheaper quote is often a thinner film or fewer pieces per bag. We normalise the comparison so the numbers mean the same thing.

What does 'silk' mean in bag thickness?

It is the Chinese trade unit for film thickness — 1 silk = 0.01 mm. So 8 silk is 0.08 mm. Always confirm whether the figure is single-layer or double-layer thickness, because suppliers quote both.

Can the bags be food-contact certified?

Food-grade material is available and documents can be requested from the supplier. Tell us the destination market, because the document that matters differs by country.
