What makes SUNWRAP a different kind of cling film manufacturer
Most "cling film manufacturers" on Alibaba are actually trading companies or converters who buy jumbo rolls from someone else and repackage them. A real manufacturer controls the entire process — and that matters because cling film quality depends on formulation decisions made at the resin-compounding stage, not at the slitting stage.
SUNWRAP is a full-process cling film manufacturer. We receive PVC resin and food-grade plasticiser (ATBC / DEHA) as raw materials and produce finished cling film through calendering, stretching, ageing, slitting, and packaging — all under one roof. This gives us three advantages that converters and traders cannot match:
- Formulation control. We adjust plasticiser ratio, anti-fog additive concentration, and stretch characteristics for each customer's end-use — supermarket hand-wrap, machine tray overwrap, HORECA catering, or industrial processing.
- Batch traceability. Every roll traces back to a specific resin lot, plasticiser batch, and production line run. When a quality question arises, we isolate the root cause in hours, not weeks.
- Price stability. No middleman margin. Our FOB price reflects resin cost + manufacturing cost + margin — nothing else. When resin prices drop, our prices follow.
Product range
As a vertically integrated cling film manufacturer, we produce:
- PVC Cling Film — 8–16 μm, 20–180 cm width, anti-fog, high-cling. Our flagship since 2004.
- PE Cling Film — LDPE/LLDPE alternative for PVC-restricted markets (EU, parts of UK/NZ).
- Jumbo Rolls — master rolls for buyers who slit and rewind to their own retail format.
- Food-Grade Retail Rolls — 1-pack, 2-pack, 6-pack retail cartons, ready for supermarket shelf.
- Industrial / Catering Film — 45 cm wide, 300–1500 m length, with or without slide cutter.
- OEM / Private Label — custom print, custom size, multilingual packaging.
Manufacturing capacity
The SUNWRAP facility in Ningbo Qianwan New Area covers 13,000+ m² with multiple calendering and extrusion lines. Monthly output capacity exceeds 2,000 tonnes of finished cling film — enough to supply a national supermarket chain's annual programme from a single factory. The 2025 relocation added a dedicated PE line alongside the established PVC programme.
Certifications & compliance
Every batch ships with full documentation:
- SGS food-contact migration test reports (heavy metals, overall migration, specific plasticiser migration)
- FDA 21 CFR 177.1975 compliance declaration (US-bound shipments)
- EU Regulation (EU) No 10/2011 Declaration of Conformity
- ISO 9001 quality management system
- Market-specific: SONCAP (Nigeria), SFDA/SABER (Saudi Arabia), BPOM (Indonesia), BIS/FSSAI (India)

Frequently Asked Questions
What does a cling film manufacturer do differently than a trader or converter?+
A manufacturer controls the entire production process from resin compounding through extrusion, stretching, slitting, and final packaging. This means full traceability of plasticiser type and dosage, consistent cling force batch to batch, and the ability to adjust formulation for specific end-use requirements. A trader resells film produced elsewhere — they cannot modify the product. A converter buys jumbo rolls and slits them, but has no control over the base film quality. SUNWRAP is a full-process manufacturer: we receive PVC resin and plasticiser as raw inputs and ship finished cling film.
How do I verify that a cling film company is a real manufacturer?+
Request three things: (1) the business licence showing PVC/PE film production in the registered scope, (2) a live video walk-through of the extrusion lines — not just a warehouse, (3) a third-party test report (SGS or CMA) issued in your company's name, not a generic PDF. A real factory will welcome a physical audit. SUNWRAP (Ningbo Sanrong New Materials Co., Ltd.) has been in continuous production since 2004 and hosts buyer audits regularly.
What is the typical MOQ when ordering from a cling film manufacturer?+
Standard export MOQ is one 20-foot container — approximately 18–22 tonnes for jumbo rolls or 8,000–12,000 retail cartons for consumer packs. However, most manufacturers (including SUNWRAP) accept trial orders of 3–5 tonnes or a few hundred cartons for first-time buyers. Trial orders help both parties validate specifications, logistics, and customs clearance before committing to a full container programme.
What certifications should a cling film manufacturer hold?+
At minimum: SGS or CMA third-party food-contact migration test reports covering heavy metals (Pb/Cd/Hg/Cr), overall migration, and specific migration of plasticisers. For US-bound shipments: FDA 21 CFR 177.1975 compliance. For EU: Declaration of Conformity per Regulation (EU) No 10/2011. ISO 9001 quality management is standard. Additional market certifications (SONCAP for Nigeria, SFDA for Saudi Arabia, BPOM for Indonesia) are available on request.
Can a cling film manufacturer produce private-label or OEM packaging?+
Yes. Full OEM services include custom colour-box printing (typically 4-colour offset), shrink-wrap bundling, bilingual or multilingual labelling (Arabic, Spanish, Vietnamese, Bahasa, French, Portuguese, and more), custom paper-core inner diameter, and custom roll dimensions. Minimum for printed retail packaging is usually 10,000 boxes, driven by printing plate economics. Artwork lead time is 5–7 working days after proof approval.
