In short: For phone cases, cables and chargers, use a 0.04–0.05 mm OPP header bag with a hang hole for peg-hook retail, a 0.03–0.05 mm clear OPP self-seal bag for inner packing, and a 0.06–0.10 mm frosted CPE or clear PE zipper bag when the brand wants a reusable, premium feel. Sizes run from 8 × 12 cm for earbuds and adapters to 14 × 22 cm for power banks and cable sets.

Film and Closure Choices
OPP gives the clearest, glossiest window and prints sharply, but it is stiff and can crack if folded; use it for flat, light items on a peg. PE and CPE are softer and do not crack, so they suit chargers, plugs and anything with hard edges. Choose a press-to-close zipper for items under 300 g and a slider zipper for heavier bundles or bags over 15 cm wide. Standard OPP, PE and CPE films are not anti-static; housed accessories do not need it, bare circuit boards do, so state that requirement separately.
Printing and Compliance Details to Put in the Spec
- Print: up to 10 colours with Pantone matching; a 1–2 colour logo on frosted CPE or a full-colour header on OPP are the usual briefs.
- Header bag: header height (3 cm standard), hole type (6 mm round or euro slot), adhesive strip on body or flap.
- Suffocation warning: required for the USA on bags with an opening of 12.7 cm (5 in) or more; see our suffocation warning guide for wording and font size.
- Eco options: PCR recycled PE, mono-material PE, or PLA/PBAT compostable film.
FAQ
What thickness should a phone case bag be?
A phone case bag works at 0.05 mm in OPP for peg display and 0.08 mm in frosted CPE or clear PE as a reusable zipper bag; both hold a 30–60 g case without puncturing.
What size bag fits a 1 m charging cable?
A coiled 1 m USB cable fits a 10 × 15 cm bag; use 12 × 18 cm if the cable is 2 m or packed with a wall adapter.
Should electronics accessories use OPP or PE bags?
Use OPP for clarity and peg display of flat, light items, and PE or frosted CPE for chargers and plugs with hard corners, because the softer film does not crack or puncture.
Do phone case and cable bags need anti-static film?
No, housed accessories such as cases, cables and chargers ship in standard OPP, PE or CPE bags; only bare boards and unhoused components need anti-static or shielding bags.
