Material Notes

Made from 100% virgin Low Density Polyethylene (LDPE) resin. Flexible and moisture-resistant at 4 mil. Nominal gauge — actual thickness may vary within standard manufacturing tolerances. FDA compliant for indirect food contact applications.

Use Case Notes

The 20″ × 30″ format accommodates items up to approximately 19″ × 29″. Standard base cabinet doors (typically 12–18″ wide × 24–30″ tall) fit within this format. For taller doors (34″ tall) or full-height panels, consider a longer bag format. The 4 mil gauge is recommended for finished surfaces where edge contact could damage lighter-gauge bags.

Common Questions

Q: Are these appropriate for protecting painted or stained cabinet doors?
A: Yes. The 4 mil LDPE film provides a protective enclosure that prevents surface contact, dust contamination, and moisture exposure for painted and stained wood cabinet doors during storage or transit.

Q: Can these hold large framed artwork safely?
A: Yes. For framed artwork up to 18 × 28 in., these bags provide a clean poly enclosure. For frames with glass, cushioning material should be added separately before bagging.
