Common material vocabulary
- Across projects, Zanfeng commonly discusses LDPE, LLDPE, PO and PP.
- Whether a material suits a particular bag format and film structure is confirmed per project.
- PO here means polyolefin — a material family, not a specific resin recipe. Do not silently replace PO with HDPE.
What still needs confirmation
- Specific film grade or blend, thickness and tolerances.
- Opening, sealing process and printing requirements.
- Special oil contact, barrier, ESD or corrosion-protection needs.
- A numeric thickness limit in a browser helper only validates the field; it does not indicate an available film thickness or bag construction.
Avoid blanket claims
- A material name alone does not establish recyclability, food contact or a certification.
- Do not promise mechanical strength or barrier performance without evidence.
- If you have an existing specification, attach it for review.
