In short: Most jewelry and small-accessory brands order press-to-close zip lock bags between 5 x 7 cm and 10 x 15 cm in 0.05–0.08 mm clear PE or PP, printed with a one- or two-color logo. Use 0.05 mm PE for studs, rings and beads, 0.06–0.08 mm high-clarity PP for display-grade necklaces and bracelets, and 0.08 mm frosted CPE for boxed sets or watches. Order one size for most SKUs and one larger size for chains and bulk packs.

Material and Thickness by Product Type
| Product | Material | Thickness | Why |
|---|---|---|---|
| Studs, rings, beads | Clear LDPE | 0.04–0.05 mm | Lowest cost, soft enough for a tight zip seal |
| Necklaces, bracelets (retail display) | High-clarity PP | 0.06–0.08 mm | Glass-like clarity for photos and hang-sell display |
| Boxed sets, watches, gift items | Frosted CPE | 0.08–0.10 mm | Softer matte feel, hides scuffs on the film |
| Bulk inner packs for wholesalers | Clear LDPE | 0.05–0.06 mm | Reclosable for picking and repacking |
PP zips are stiffer than PE zips, so specify PP only when the bag is part of the retail display; PE seals more reliably on a packing line. For micron and mil equivalents, see the thickness conversion guide.
Printing Specs That Work at Small Sizes
Keep the logo to one or two Pantone colors and at least 1.5 cm wide on bags under 7 cm. Print on the front panel only, at least 5 mm below the zipper line, because the zipper area cannot hold ink. A 3 x 2 cm white block serves as a write-on SKU label. A 6 mm hang hole or euro slot above the zipper is standard on 7 x 10 cm and larger bags. For press-to-close versus slider closures, see our zipper type comparison.
How to Write the Purchase Spec
- Size: width x height in cm, stating whether height includes the 1–1.5 cm lip above the zipper.
- Material and thickness: LDPE 0.05 mm, PP 0.07 mm or frosted CPE 0.08 mm; single-material PE if the bag must be recyclable in one stream.
- Zipper: single-track for bags under 10 cm, double-track for larger bags or contents over 50 g.
- Print: number of colors, Pantone codes, logo position in mm from the bottom edge.
- Packing: bags per inner pack (100 or 200 is standard) and inner packs per carton.

FAQ
What thickness should a jewelry zip lock bag be?
Use 0.04–0.05 mm for studs and rings, 0.06–0.08 mm for necklaces and bracelets, and 0.08–0.10 mm for sharp metal parts or gift boxes.
Is PE or PP better for jewelry bags?
PP gives higher clarity for retail display, while PE is softer, cheaper and seals more easily, so PE is the default for packing-line use.
Can a logo be printed on a 5 x 7 cm bag?
Yes, a one- or two-color logo at least 1.5 cm wide prints cleanly on a 5 x 7 cm bag as long as it sits at least 5 mm below the zipper.
